## Objective hearing loss test tool,hearing damage letra en espa?ol xo,my ears are stuffy and ringing jobs - Step 3

In order to understand how the ear functions we need to know something about what a sound is and how it behaves. The vibration of an object, a sound source, causes waves to be transmitted through air (usually) to our ears. Air particles are in constant random motion, exerting very small pressure variations around the steady-state atmospheric pressure.
Air particles themselves do not move very far, they simply transfer pressure changes by what is referred to as sound propagation.
Reflected sound may encounter the original sound wave and, depending on the relative timing of the two, they may either reinforce or cancel one another.
Sound waves may also be diffracted, which means that, depending on the frequency of the sound, they are able to wrap around small or medium-size objects (like the head for example). We could use any of several physical quantities to describe the strength of a sound wave, but it is most convenient to use sound pressure, which is the extremely small alternating deviation above and below atmospheric pressure due to the propagated wave of compression and rarefaction. The frequency of a pure tone is the number of cycles or complete oscillations of condensation and rarefaction in one second. The period of a pure tone is the time required for one complete cycle, or the time that elapses between two successive condensation or rarefaction peaks.
Because the ear operates over a range of sound pressures (its dynamic range) which is greater than a million to one, stimulus strength is usually expressed in logarithmic units known as decibels (dB). If, for example, the sound pressure from one source (P1) is is ten times greater than that from a second (P2), the difference is 20 dB.
The chart below shows on a dB scale the sound pressure level of sounds common to our everyday environment. We also note on the graph the frequencies and sound pressure levels associated with normal conversational speech. The following information has been compiled to help spread the good news with the hope of placing more people onA the path to greater health, relaxation and happiness. I-1) Distribution of air particles when a sound source is vibrated as afunction of distance in the direction of sound propagation.
1) the wavelength is the distance between two successive peaks on the wave; it may be calculated by dividing the velocity of wave propagation by the frequency.
Using a far infrared sauna can help strengthen the bodya€™s immune system by stimulating increased production of white blood cells by the bone marrow and killer T-cells by the thymus.A 2. Far infrared rays improve blood circulation, stimulate endorphins, lower lactic acid, kill certain bacteria and parasites, and burn calories. Proponents of hyperthermia, also known as fever therapy, maintain that using far infrared energy to therapeutically induce higher body temperatures helps fight infections and even cancer. Their argument is supported by the human body itself, which radiates infrared energy for the benefits of warmth and tissue repair.A 3.
This is the heat you feel penetrate your skin when you stand in the sun and miss when you walk into the shade. When people do not receive adequate amounts of far infrared heat, they often can become ill or depressed.A 4. Far infrared saunas are recognized by health practitioners worldwide as perhaps the most effective method of removing both chemical and heavy metal toxins from the body.
Far infrared saunas are thought to be 7 times more effective at detoxifying heavy metals such as mercury, aluminium, and other environmental toxins than conventional heat or steam saunas. For many chronically ill patients as well as people who are well and wish to stay that way by reducing their toxic burden, the far infrared sauna is the detox method of choice.A 6. Bathing in a far infrared sauna in the early stages of a cold or flu has been known to stop the disease before symptoms occur.A 7. Far infrared heat can penetrate into the skin about an inch and a half to two inches deep and can have therapeutic benefits, such as helping to dissolve fat deposits under the skin. Since toxins may be stored in the fat, the deep penetrating heat of a far infrared sauna can help eliminate them, especially toxins such as heavy metals and acidic compounds.A 8. The radiant heat of a far infrared sauna is efficient because it warms the sauna bather directly. The body absorbs as much as 93 percent of the heat, causing perspiration and producing a vast array of health benefits.A 9. Far infrared saunas can help clear cellulite, the gel-like lumps of fat, water and debris trapped in pockets beneath the skin.
European beauty specialists routinely incorporate daily far infrared sauna baths in programs to reduce cellulite.A 10.
Generally speaking, far infrared saunas are less expensive, easier to install, and require less maintenance than traditional saunas.
They come in many sizes and are often quite portable, making them a great choice when limited space is available.A 11. Far infrared radiant heat provides all the healthy benefits of natural sunlight without any of the dangerous effects of solar radiation.A 12.
Far infrared saunas are more cleansing than conventional saunas because they are designed to generate more than two to three times the amount of perspiration.
Unlike in traditional saunas where temperatures range from 140 to 220 degrees Fahrenheit (60 to 105 degrees Celsius), the temperatures of far infrared saunas typically range from 100 to 140 degrees Fahrenheit (38 to 60 degrees Celsius).A 14. This allows a person to perspire faster and to tolerate a longer period of time inside the sauna. Typical sessions in a far infrared sauna last 20 to 30 minutes and can be repeated to maximize the benefits.A 15. The lower heat range of far infrared saunas is safer for people with cardiovascular risk factors or fragile health because lower temperatures dona€™t dramatically elevate heart rate and blood pressure.A 16. Far infrared saunas have been used to treat sprains, bursitis, rheumatism, muscle spasms, neuralgia and hemorrhoids. The effects of toxin, chemical and pesticide poisoning can be greatly reduced by the far infrared saunaa€™s detoxification action. People who work with chemicals, as well as home gardeners who frequently use fertilizers and pesticides, are advised to use far infrared saunas on a regular basis.A 18. Far infrared radiant heat is a form of naturally occurring energy that heats objects by direct light conversion. Direct light conversion warms only the object and does not raise the temperature of the surrounding free air.A 19.
Far infrared sauna use can help promote rebuilding of injured tissue by having a positive effect on the fibroblasts, the connective tissue cells necessary for the repair of injury. It also can help increase growth of cells, DNA syntheses, and protein synthesis, all of which is necessary during tissue repair and regeneration.A 21. In the electromagnetic spectrum, far infrared wavelengths measure between 5.6 and 1,000 microns. Wavelengths of between 6 and 14 microns are believed to be the most beneficial to humans and other living things on Earth.A  The human palm emits far infrared wavelengths of between 8 and 12 microns. The energy output from far infrared saunas so closely match the human bodya€™s radiant energy that nearly 93 percent of the saunaa€™s far infrared waves reach the skin.A 22.
Far infrared sauna therapy has helped people with cardiovascular conditions such as congestive heart failure and angina. It enhances endothelial nitric oxide, lowering blood pressure and improving cardiovascular function.A 23. The radiant heat of far infrared saunas has been shown to be especially beneficial to people with sports injuries, fibromyalgia, arthritis, and other chronic pain conditions.A 24.
There are some definite advantages to using far infrared sauna thermal heaters, such as no high heat claustrophobic reaction and better air circulation. Far infrared heaters heat the body, not the air, so a bather is more comfortable and cooler. Far infrared saunas require 90 percent less electrical energy than conventional saunas, and no plumbing is required for a far infrared sauna.A 26. A 20 to 30-minute session in a far infrared sauna has been touted to burn as many calories as a six-mile run.A 27.
Far infrared saunas are now used in health facilities for a range of health problems such as menopause, ulcers, insomnia, asthma, bronchitis, ear infections, and allergies.A 28.
You dona€™t have to worry about setting the sauna up on a waterproof floor or near plumbing, and you dona€™t have to worry about mildew.A 29. Unlike a traditional sauna, which requires a closed atmosphere to maintain heat levels required for therapeutic results, a far infrared sauna can be used with its door or window completely open if far infrared penetration is the only objective.A 30.
Infrared light lies between the visible and microwave portions of the electromagnetic spectrum. Infrared light has a range of wavelengths, just like visible light has wavelengths that range from red light to violet. Near infrared light is closest in wavelength to visible light, and far infrared light is closer to the microwave region of the electromagnetic spectrum. A far infrared sauna is usually warm within 10 or 15 minutes, whereas a conventional sauna can take more than an hour to reach optimal temperatures.A 33.
Another option, although quite costly, is to use far infrared bulbs, which can provide warming and stimulating color therapy.A 34. In addition to hemlock, wood choices for far infrared sauna construction include basswood, birch, oak, poplar, spruce and western red cedar. When a wood type is stated to be hypoallergenic, it means that the wood contains minimal allergens and is therefore less likely to cause an allergic reaction. When far infrared heat penetrates a bathera€™s body, he or she can experience a refreshed mind, relaxed mood, reduction of aches and pains, improved metabolism, and systemic regularity leading to an overall feeling of wellness.A 37. Hemlock is a very strong wood that is quite able to withstand the heat of a far infrared sauna. It is also abundantly available, which means the end cost to the consumer is less than it might be for another wood type.A 38. Far infrared radiation is believed to be the only antidote to excessive ultraviolet radiation.A 39. Certain alternative healing practices such as palm healing, a practice with some 3,000 years of tradition behind it in China, rely on the human bodya€™s ability to emit far infrared radiant energy.A 40. And weight gain, muscle loss, decreased libido, wrinkles in our skin, and a growing number of aches and pains are probably other distressing concerns.A Some people try to defy nature by undergoing cosmetic surgery, utilizing every a€?anti-aginga€? skin care product available, taking stress management or meditation courses, or relocating to less polluted areas. These actions may have merits worthy of consideration, but the fact remains that no one, no matter how determined he or she may be, can slow down the passage of time. We start aging even before we are born, and the process does not stop until the day we die.A While our efforts may not influence time itself, they can, however, affect how our bodies respond to and endure it.
Qualified health professionals agree, for example, that regular exercise and good nutrition can have a long-term positive impact on a persona€™s quality of life.
As well, avoiding the dangerous ultraviolet rays of the sun is universally regarded as an effective way to help maintain healthy, youthful skin. And leta€™s not forget how quitting smoking has been shown to improve respiratory health and reduce the risk of cancer in many vital bodily organs. A One activity that has been proven to be of great benefit to the lungs, heart, skin and other organs is far infrared sauna bathing.
The rays from a far infrared sauna can help improve cardiovascular functioning, strengthen the bodya€™s immune system, reduce fat and cellulite, revitalize skin cells, improve muscle tone and strength, improve nutrition and production of brain chemicals, and much more.A Far infrared sauna bathing also helps to flush toxic chemicals, heavy metals and other destructive agents from our bodies.
Penetrating as deeply as three inches into our bodies, far infrared rays improve blood circulation, stimulate endorphins, destroy certain bacteria and parasites, lower lactic acid, and burn calories.Advocates of hyperthermia, also known as fever therapy, contend that employing such deep-penetrating far infrared energy to therapeutically induce higher body temperatures helps combat infections and even cancer.
Their assertion is supported by the human body itself, which emits infrared energy for purposes of warmth and tissue repair.A Saunas have long been a tried, tested and true source of health benefits. For centuries, traditional saunas have helped to improve cardiovascular function, promote body detoxification, maintain general health, and foster greater relaxation in sauna bathers around the world.
For many sauna enthusiasts, the traditional hot sauna a€“ the Finnish sauna a€“ remains the preferred route to renewed health and a rejuvenated spirit.A Sometimes called radiant heat saunas, soft heat saunas or heat therapy rooms, far infrared saunas offer most of the same benefits that traditional Finnish saunas do, but they do so at lower, more tolerable temperatures.
While the air temperature in a typical Finnish sauna bath ranges from 170 to 200 degrees Fahrenheit (77 to 93 degrees Celsius), such temperatures arena€™t required in a far infrared sauna to induce optimal bather perspiration.A By penetrating the bathera€™s body and effecting a deep, satisfying heat of just 100 to 130 degrees Fahrenheit (38 to 55 degrees Celsius), the far infrared rays can create an enjoyably cleansing, detoxifying and revitalizing experience for the bather. In fact, many sources claim that the volume of sweat produced during a far infrared sauna bath can be as much as three times greater than in a Finnish sauna bath.

The higher volume of sweat means a faster, more thorough, and thus more beneficial flushing of toxic chemicals and harmful heavy metals from the body.A Far infrared rays are a fundamental, indispensable part of life on Earth.
And now, with far infrared heat therapy rooms and other infrared applications becoming increasingly common, we humans are wisely taking action to benefit from those rays and improve the quality of our own lives.A Benefits of Far Infrared Sauna UseThere are many benefits to be derived from proper and regular use of a far infrared sauna. Far infrared sauna bathing can improve autonomic functions of the nervous system.Further Applications of Far Infrared EnergyFar infrared saunas are just one example of the application of infrared energy in contemporary society. Other uses of infrared energy have resulted in infrared hair dryers, infrared foot massagers, infrared pillows, infrared underwear, and even infrared leg wraps for horses. There are far infrared ray-emitting paints and wallpaper that combat mold as well as fast-cooking far infrared ovens that reportedly kill E. Far infrared rays are being utilized to purify polluted air, promote growth in plants, keep newborn babies warm in hospitals, treat injured athletes, and even encourage new hair growth.Far Infrared Is Essential to LifeFar infrared rays are a fundamental, indispensable part of life on Earth. And now, with far infrared saunas and other infrared applications becoming increasingly common, we humans are astutely taking steps to benefit from those remarkable rays and improve the quality of our own lives. Similarly, you may not pay much attention to far infrared saunas, but these fantastic devices offer health benefits that you may not be able to afford to ignore any longer.A As time progresses, it seems that the world is becoming an increasingly dangerous place. We live in an age of terrorist activities, nuclear weapons, dictatorships and religious fanaticism. Costly international conflicts show no sign of abating, and just about everyone feels more insecure and vulnerable than they did a decade ago. Even in our local neighborhoods, many of us worry about rising crime rates and growing threats to our personal safety.A And, as if those problems were not enough for us to worry about, many of us have major health issues with which we have no choice but to contend.
Not helping matters are all the poisons and contaminants that have found their way into our environment and into our bodies.
Fortunately, though, we are not powerless against these mighty and malicious microscopic menaces. In fact, we can start doing something about them right now - we can start fighting back with far infrared sauna detoxification therapy.A Far infrared saunas are revered by scientists and health professionals around the world for their ability to help flush out many of the toxic chemicals, heavy metals and other destructive agents that have accumulated deep within the bloodstream, skin and other vital organs of people from all walks of life. For individuals affected by mercury toxicity, lead poisoning, and other life-threatening exposures, the far infrared sauna is often viewed as an essential component of detoxification therapy.A If you think that only people in high-risk occupations qualify for far infrared sauna detoxification therapy, youa€™re wrong. Exogenous toxins, which can be absorbed through the skin, respiratory tract and gastrointestinal tract, are those not produced by the body itself, and examples include mercury, lead, zinc and cadmium. Sylver writes that a€?this category consists of waste produced by the body in the course of normal metabolic functioning and also pathogens (viruses, bacteria, fungi and parasites) and the waste they excrete.
Also known as chronic fatigue and immune dysfunction syndrome (CFIDS), CFS was once commonly referred to as the a€?yuppie flua€? after about 200 people, most of whom were white, wealthy, young females, come down with a strange illness in 1984.
National Institutes of Health claim that, for some people, chronic fatigue syndrome can first appear after a cold, bronchitis, hepatitis or an intestinal bug; for others, it can follow a bout of glandular fever.
CDC and CFIDS Association of America announced in 2001 that stress may exacerbate but most likely does not cause the disorder.A On the polemical subject of CFS prevalence, Dr.
Buist asserts that toxins can impede muscle metabolism, causing the pain and fatigability of muscles felt by many fatigued people.A Addressing the Well Mind Association in Seattle, WA, Dr. The affected persona€™s detoxification system is clogged up or destroyed, they get a backlog of chemicals, and their immune system goes down.a€?A Dr. Edelson and Deborah Mitchell, authors of What Your Doctor May Not Tell You About Autoimmune Disorders, put it like this: a€?The hallmark of CFIDS is overwhelming, persistent, incapacitating fatigue that leaves those afflicted unable to carry on their normal physical functions.
Schmidt writes, a€?Researchers at Uppsala University Medical School in Sweden reported that patients with chronic fatigue contain abnormal levels of mercury within their cells. Of patients with chronic fatigue, 45 percent showed mercury hypersensitivity and 49 percent showed lead hypersensitivity.
When the metal burden was removed from the body (in many cases, by removing mercury-containing silver dental fillings), 77 percent of patients reported improved health.a€?A If these conclusions are correct, how can sufferers retaliate after the damage of toxic build-up has manifested itself as chronic fatigue syndrome?
Lyon recommend far infrared sauna therapy.A a€?For the chronic fatigue patient, a consistent program of infrared sauna therapy will assist the problem of autonomic dysregulation, which is common to the condition,a€? states Dr. These symptoms are reduced, as regular sauna therapy induces normal autonomic functioning.A a€?Through extensive research, it has been shown that saunas greatly assist in the elimination of accumulated toxins,a€? Lyon adds. It has become well known that people who take regular saunas (2-3 per week) reduce their incidence of colds and influenza by over 65% (a study by the British Medical Association). While many people use saunas primarily for relaxation and stress reduction, the other health benefits are increasing the popularity of saunas. An often agonizing muscle disorder in which the thin film or tissue holding muscle together becomes thickened or tightened, fibromyalgia is characterized by widespread musculoskeletal aches, pains and stiffness, soft tissue tenderness, mild to incapacitating fatigue, and disturbed sleep.A The pain of fibromyalgia is typically felt in the neck, back, shoulders and hands, but it is not exclusive to those areas. Based on criteria set in 1990 by the American College of Rheumatology (ACR), a diagnosis of fibromyalgia requires a patient to have experienced widespread pain for a minimum of three months in 11 of 18 tender muscle sites. Among those 18 sites are the hips, knees and rib cage.A Other symptoms of fibromyalgia include allergies, anxiety, carpal tunnel syndrome, depression, dizziness, headaches, irritable bowel symptoms, numbness, and tender skin. Most sufferers of fibromyalgia are women of childbearing age, but it has also been known to strike men, children and the elderly.As for what causes fibromyalgia, many theories exist. The Alternative Medicine Guide to Chronic Fatigue, Fibromyalgia and Environmental Illness states that a€?post-traumatic fibromyalgia is believed to develop after a fall, whiplash or back strain, whereas primary fibromyalgia has an uncertain origin.a€? However, in her book Detoxify or Die, Dr. Nenah Sylver extols the sauna for its ability to increase cardiovascular activity and white blood cell, enzyme, and norepinephrine, beta-endorphin and possibly thyroxin production. As they, in turn, help to enhance circulation, increase waste removal and nutrient absorption, raise metabolism, and promote the elimination of toxins, foreign proteins and microbes, Dr.
Sylver deems the aforementioned benefits of proper sauna use crucial in helping people with fibromyalgia. She notes a€?there are actually very few health problems that cannot be helped (or would become worse) with sauna therapya€? but advises patients nevertheless to consult with their health providers before beginning sauna therapy.A Dr. Rogers and other health professionals insist that the far infrared sauna, radiant heat sauna or heat therapy room is of greater benefit to fibromyalgia sufferers than the traditional hot Finnish sauna because of a fundamental difference between the two styles of sauna. Rogers calls the far infrared sauna a€?infinitely more tolerable,a€? particularly for people with fibromyalgia, chronic fatigue syndrome or multiple sclerosis, because it can function effectively at a much lower temperature than a conventional Finnish sauna.A a€?Ia€™m convinced that the far infrared sauna is something that everyone should do to restore health,a€? declares Dr. That such an effective detoxification tool exists should be welcome news to anyone suffering the ill effects of excessive lead, mercury, cadmium, arsenic or aluminium in his or her body. A Not everyone may believe they have sufficient reason to worry about heavy metal and chemical toxicity, but many experts are urging the skeptics to think again. Lead is a highly toxic substance, exposure to which can produce a wide range of adverse health effects.
In adults, lead can reportedly increase blood pressure and cause fertility problems, nerve disorders, muscle and joint pain, irritability, and memory or concentration problems.
A Because their brains and central nervous systems are still being formed, young children under the age of six are especially vulnerable to leada€™s harmful health effects. National Safety Council (NSC), a€?Even very low levels of exposure can result in reduced IQ, learning disabilities, attention deficit disorders, behavioral problems, stunted growth, impaired hearing, and kidney damage. Lead can also be found in automobile exhaust, pesticides, hair dye, ink, and some glazed dishware.Mercury, a ubiquitous environmental pollutant that can be found in tuna and swordfish, latex paint, dental amalgams, vaccines, cosmetics, contact lens solution, fabric softener and tap water, has also been classified by researchers as posing a grave threat to human health. In fact, the World Health Organization (WHO) has declared that no level of mercury can be considered to be safe, as it is the most toxic non-radioactive element on Earth.A In their book What Your Doctor May Not Be Telling You About Autoimmune Disorders, Dr. Like so many other heavy metals, cadmium can be found in air, water, soil and food.A Noting that the highest contributor to cadmium toxicity is cigarette smoke, the Center for Environmental and Integrative Medicine (CEIM) in Knoxville, TN, states that a€?cadmium can weaken the immune system and allow bacteria, viruses, yeast and parasites to proliferate.
Cadmium may also promote skeletal demineralization and increase bone fragility and fracture risk. Department of Health and Human Servicesa€™ Agency for Toxic Substances and Disease Registry (ATSDR). Eating food or drinking water with very high cadmium levels severely irritates the stomach, leading to vomiting and diarrhea, and sometimes death.
Breathing air with lower levels of cadmium, or eating lower levels of cadmium, over long periods of time can result in a build-up of cadmium in the kidneys. This has been seen mostly in workers exposed to arsenic at smelters, mines, and chemical factories, but also in residents living near smelters and arsenical chemical factories.
Environmental Protection Agency (EPA), and the International Agency for Research on Cancer (IARC) have all classified inorganic arsenic as a known human carcinogen.A Since arsenic is found naturally in the environment, humans risk exposure to it when they eat food, drink water, breathe air, or come in contact with contaminated soil or water. The same can be said for aluminium compounds.A People may also be exposing themselves to aluminium compounds when they ingest medicinal products like certain antacids, laxatives and buffered aspirin or have skin contact with aluminium metal, antiperspirants, or other substances that contain aluminium or aluminium compounds. Mercola asserts that aluminium has been linked to serious illnesses such as osteoporosis, extreme nervousness, anemia, headache, decreased liver and kidney function, speech disturbances, and memory loss.
He also contends that people who have died from Alzheimera€™s disease have been found to have up to four times the average amount of aluminium accumulated in the braina€™s nerve cells.A Offering its view on the subject, the ATSDR states that exposure to aluminium is usually not harmful but notes that some people who have kidney disease store a lot of aluminium in their bodies. In these children, the bone damage is caused by aluminium in the stomach preventing the absorption of phosphate, (which is) required for healthy bones.a€?Lead, mercury, cadmium, arsenic and aluminium are just five of an intimidating number of toxins capable of severely compromising your health. Among the other heavy metals most often found at unacceptable levels in the body, according to Edelson and Mitchell, are nickel and tin. Sherry Rogers writes, a€?The lungs, urine, stool and sweat are the main vehicles the body has for getting rid of nasty chemicals, but by far sweat is the most efficacious. And Mayo Clinic studies show that (utilizing) far infrared energy is the safest way to induce healing sweata€¦ Far infrared sauna technology is the only proven, most efficacious way of getting rid of stored environmental chemicals.a€?A A far infrared sauna has been cited as the best place to sweat because, whereas bathing in a conventional hot air sauna produces perspiration that is composed of approximately 97 percent water and three percent toxins, soaking in a far infrared sauna has been shown to produce sweat composed of about 80 percent water and 20 percent toxins. As well, far infrared saunas can produce up to three times the sweat volume of a conventional hot air sauna while operating at a considerably cooler air temperature range of 110 to 130 degrees versus 180 to 235 degrees for hot air saunas. Ita€™s worthwhile to also note that, according to author and sauna historian Mikkel Aaland, a 15-minute far infrared sauna session can execute the same heavy metal excretion that would take the kidneys 24 working hours. In other words, sweating in a far infrared sauna can be a very efficient method of detoxification.A Even though sweating is a natural function of the human body, many people do not perspire properly because their skin has been damaged or deactivated by, among other culprits, chemicals in bath water, lotions, soaps and deodorants.
Fortunately for these people, far infrared sauna therapy can greatly help to restore the skina€™s eliminative powers. Ita€™s just one more way far infrared saunas work to heal bodies compromised by harmful chemicals.A If you are concerned about how harmful chemicals and heavy metals can affect your health, consider the many benefits of owning a far infrared sauna. Most people have a casual understanding of each of those three, but it is the mercury included in the periodic table of elements that demands greater public contemplation. For if contemporary society placed more of an emphasis on the pernicious effects of mercury exposure, perhaps fewer people would be victimized by related illnesses and diseases.A Mercury is the most toxic non-radioactive element on Earth, and the World Health Organization (WHO) has proclaimed that no level of mercury can be regarded as being safe. Centers for Disease Control and Prevention (CDC) announced in a 2001 study that one in every 10 American women of childbearing age is at risk for having a baby born with neurological problems due to mercury exposure.A There are three principal types of mercury, and each type presents a serious health hazard to humans.
The first type, elemental mercury, is a liquid that gives off mercury vapor at room temperature. Elemental mercury can also enter the bloodstream by permeating the skin.A Inorganic mercury compounds, the second type, can also be inhaled as well as pass through the skin. Unlike elemental mercury, though, inorganic mercury compounds can also be absorbed through the stomach if swallowed. Elemental mercury, if swallowed, is not absorbed and usually exits the body without causing any harm. Many inorganic mercury compounds are irritating or corrosive to the skin, eyes and mucus membranes.A The third type of mercury, organic mercury compounds, can enter the body by way of all three routes a€“ lungs, skin and stomach. Exposure to any form of mercury on a repeated basis, or even a very high single dose, can lead to chronic mercury poisoning. According to the New Jersey State Department of Health, chronic mercury poisoning is characterized by three major symptoms:Gum problems. People with chronic mercury poisoning frequently experience wide mood swings, becoming irritable, frightened, excited or depressed very quickly for no apparent reason. Some people may become extremely upset at any criticism, lose all self-confidence, and become apathetic. Memory loss, hallucinations, and inability to concentrate can also occur.Nervous system impairment. The earliest and most frequent symptom of chronic mercury poisoning is a fine tremor of the hand. A person with chronic mercury poisoning may also experience difficulty balancing and walking.A In What Your Doctor May Not Be Telling You About Autoimmune Disorders, authors Dr. Research has demonstrated that the bodya€™s tissues, especially in the brain, kidneys, jaw, lungs, gastrointestinal tract, and liver, absorb and store mercury.a€?A With such research findings having caught the publica€™s attention, some people have begun insisting that their dentists use composite fillings, also known as a€?white fillings,a€? as a non-toxic alternative to amalgam fillings. As well, some dental patients are demanding that their existing amalgam fillings be removed and replaced with composite fillings.A In her book Detoxify or Die, Dr.
Rogers writes, a€?Autoimmune disease, heart disease, high cholesterol and triglycerides, chemical sensitivity, allergies, antibiotic-resistant infections, depression, schizophrenia, multiple sclerosis, leukemia and just about any symptom you can think of have improved once sufficient accumulated mercury was removed from the teeth and body.a€?Going a step further, Dr. Daniel Royal, member of the Nevada State Board of Homeopathic Medical Examiners, states, a€?While removal of amalgam fillings stops further poisoning from mercury fillings, you still need to detoxify the body to eliminate the residual effect from mercury that remains behind in the body.
Royal calls the sauna a useful adjunct to safe mercury removal because it induces profuse sweating. One reason is that far infrared saunas, also known as radiant heat saunas or soft heat saunas, can effectively function at temperatures lower than those characteristic of traditional hot Finnish saunas.
The findings of this study make a strong case that far infrared saunas are simply better detoxification devices than conventional hot saunas.A Before you begin a sauna detoxification program, or if you suspect that you suffer from mercury poisoning, you should discuss your plans or share your suspicions with a qualified health professional. And if you decide to purchase a far infrared sauna for any of its many therapeutic properties, be sure to research your choices thoroughly, as satisfied sauna buyers are typically well-informed sauna buyers.A Opening the Sauna Door to Better Healthby Pertti Olavi Jalasjaa You may think of a home sauna as being little more than a luxury, an object that offers pleasure and comfort but is ultimately inessential to your well-being. However, the results of decades of research may just convince you of what sauna enthusiasts have believed for centuries a€“ that regular sauna bathing offers significant, perhaps even life-saving, health benefits.A A chief objective of any sauna bath is to make you perspire, and perspiration is a natural, necessary function of the human body.
Ita€™s a means by which the body can rid itself of extra heat and water and eliminate harmful toxins that have, over time, built up inside it.
Included among these toxins are mercury, lead, cadmium and aluminium.A The health benefits of sauna bathing, however, go beyond aiding detoxification. As your body increases sweat production to cool itself during a hot sauna bath, your heart increases blood circulation.
Heart rate, cardiac output and metabolic rate all increase, while diastolic blood pressure decreases, helping to improve overall cardiovascular fitness.A Sauna bathing may also contribute to healthy weight loss. A letter in a 1981 issue of the Journal of the American Medical Association asserted that a€?a moderately conditioned person can easily a€?sweat offa€™ 500 grams in a sauna, consuming nearly 300 calories, the equivalent of running two to three miles.
A heat-conditioned person can easily sweat off 600 to 800 calories with no adverse effects. While the weight of the water lost can be regained by rehydration with water, the calories consumed will not be.a€?A Most irrefutable are the claims that regular sauna bathing helps to relieve stress and promote relaxation. It has been demonstrated time and time again that spending just a few minutes in a hot sauna bath can reduce anxiety levels, sooth nerves and warm tight muscles. Not only has sauna bathing been shown to encourage deeper, more restful sleep, far infrared sauna therapy has proved effective in alleviating pain associated with arthritis, backache, bursitis, fibromyalgia, headache, sprains, strains and other muscular and skeletal ailments.A a€?I am convinced that the far infrared sauna is something that everyone should do to restore health,a€? contends Dr. And while the condition known as Raynauda€™s disease has perhaps not received as much attention as those previously mentioned, credible sources suggest that sauna bathing can benefit its sufferers as well.A Raynauda€™s disease is a condition that causes some areas of your body, such as your fingers, toes, ears, cheeks, tongue, and the tip of your nose, to feel numb and cool in response to cold temperatures or stress.

Named after Maurice Raynaud, the French physician who first described it in 1862, it is a disorder of the blood vessels that supply blood to your skin.
During a Raynauda€™s attack, these arteries narrow, limiting blood flow to affected areas.A Accurately discussing Raynauda€™s can be challenging for some people, as two types of it exist, and each type has two names.
What most laymen generically call Raynauda€™s disease could be either primary Raynauda€™s or secondary Raynauda€™s.A Primary Raynauda€™s, the most common form of the disorder, is what physicians and medical textbooks correctly refer to as Raynauda€™s disease. Although anyone can develop the condition, primary Raynauda€™s mainly affects women between the ages of 15 and 40. Ita€™s also more common in people who live in colder climates.A Secondary Raynauda€™s, also known as Raynauda€™s phenomenon, is caused by an underlying problem like scleroderma, Sjogrena€™s syndrome (both connective tissue diseases), lupus (an autoimmune disease), rheumatoid arthritis (an inflammatory disease), hypothyroidism (an underactive thyroid gland), diseases of the arteries (such as atherosclerosis and Buergera€™s disease), carpal tunnel syndrome, nerve damage, or chemical exposure. As well, people in certain occupations, such as those who operate vibrating tools, may be more vulnerable to secondary Raynauda€™s.A Most typically, cold temperatures provoke Raynauda€™s attacks. Just taking an item out of your freezer, putting your hands in cold water, or exposing yourself to cold air could trigger one. For some people, however, cold is not even necessary; emotional stress is enough to instigate an episode. In both cases, the body seems to exaggerate its natural response of trying to preserve its core temperature by slowing blood supply to its extremities. During an attack, which can last from less than a minute to several hours, affected areas of your skin usually first turn white.
As your blood circulation improves, the affected areas may turn red, throb, tingle or swell. Raynauda€™s attacks may grow more severe over time.A If the condition becomes severe, blood circulation to your extremities could permanently diminish, resulting in deformities in affected areas like your fingers or toes. Also, skin ulcers or gangrene could develop if an artery to an affected area becomes completely blocked.A Depending on the cause and severity of symptoms, treatment can take many forms. Medications may include alpha blockers, calcium channel blockers, or vasodilators, all of which help relax blood vessels.
For example, during a session in either type of sauna, the bathera€™s heart responds to the sauna heat by increasing blood flow and perspiration production to cool the bathera€™s body.
Around the globe, doctors, researchers and other professionals have discovered the tremendous value of using sauna heat to help increase the human bodya€™s white blood cell count, stimulate its immune system, facilitate detoxification, and produce a state of general relaxation that is vital to the healing process.A In many countries, experts continue to research the therapeutic properties of the sauna.
Chuwa Tei, professor of medicine and chair of the department of internal medicine at Japana€™s Kagoshima University, and his colleagues have demonstrated saunasa€™ usefulness in treating heart patients.A In one study, Tei and his colleagues compared 25 men with at least one risk factor for heart disease, such as diabetes, high blood pressure, high cholesterol or smoking, with a group of 10 healthy men. Each study participant spent 15 minutes in a 140-degree Fahrenheit (60-degree Celsius) dry sauna, followed by 30 minutes in a bed covered with blankets, once a day for two weeks. The researchers then measured how well the participantsa€™ blood vessels expanded and contracted, a sign of the health of the vessels.
The researchers also found that the sauna therapy lowered participantsa€™ blood pressure slightly. The results of the study should be encouraging to anyone concerned about blood vessel diseases like atherosclerosis (hardening of the arteries) and erectile dysfunction.In earlier studies, Tei and his colleagues demonstrated that sauna therapy improved the blood vessel function in hamsters with chronic heart failure.
The hamsters that received sauna therapy also lived about three weeks longer than those that didna€™t receive sauna therapy.A German researchers recently studied 22 kindergarten children who took weekly sauna baths and compared them to a group of children that did not take any sauna baths.
Both groups were followed for 18 months and closely monitored for any occurrence of ear infections, colds, or upper respiratory problems. The researchers found that the children who did not take the weekly sauna baths took twice as many sick days as their counterparts.A Other findings suggest that it may be more than the heat of a sauna that is so advantageous to human health. Tests have indicated that the practice of tossing or splashing water on heated rocks in a traditional Finnish sauna produces a high quantity of negative ions in the air.
Research has concluded that air abundant with negative ions offers great benefits, while a lack of negative ions or a higher ration of positive to negative ions in the air we breathe can cause physical harm.And while a June 2001 edition of The St. Lying above the 60th parallel, the southern boundary of the Arctic Circle, northernmost Finland receives little sunlight during the winter, which typically begins in November and lasts at least until May. Throughout all of Finland, winter days are remarkably short, with the sun low on the horizon even at midday. In the far north, the period known as a€?kaamosa€? or polar night, during which the sun never rises above the horizon, is nearly two months long.A Light deprivation is a serious concern during Finnish winters, particularly in areas where continuous darkness stretches several weeks. Many experts believe it could explain why Finland has one of the worlda€™s highest suicide rates. Each year, 14 percent of northern populations reportedly experience the a€?winter blues,a€? and another six percent suffer from the more serious Seasonal Affective Disorder (SAD), a type of clinical depression that, by definition, afflicts people only at certain times of the year. A In addition to depression, common symptoms of SAD include anxiety, fatigue and low energy, irritability, increased sleeping, difficulty concentrating, and changes in appetite, most notably carbohydrate cravings.A For many people, Seasonal Affective Disorder is a seriously disabling illness that prevents them from functioning normally without continuous medical treatment.
For others, it is a mild but debilitating condition that causes discomfort but not severe suffering.
This milder form of SAD, called Subsyndromal Seasonal Affective Disorder, is what most people perceive to be the aforementioned winter blues.A Yet another form of SAD is Reverse Seasonal Affective Disorder (RSAD), and it typically strikes during the late spring or early summer and lasts throughout the warmer months. Also known as summer depression, RSAD is characterized by decreased sleep, weight loss, poor appetite, and other symptoms.
Because treatment options can differ for SAD and RSAD, ita€™s important to note that the information in the following paragraphs pertains specifically to SAD a€“ in other words, winter depression.A According to the American Academy of Family Physicians, treatments for Seasonal Affective Disorder include monoamine oxidase inhibitors (MAOs), psychotherapy, and light therapy. Certain sources claim that, in addition to being used to treat SAD, insomnia and jet lag, light therapy can also be beneficial for people suffering from skin conditions such as acne, eczema, psoriasis and vitiglio.A For treating Seasonal Affective Disorder, the most commonly used phototherapy equipment is a portable lighting device known as a light box. The patient sits in front of the box for a prescribed period of time that can be as brief as 15 minutes or as long as several hours. The duration and frequency of light therapy sessions often depend on the patienta€™s physical needs and lifestyle. As one might surmise, light therapy sessions for SAD typically begin in the autumn months and continue throughout the winter, sometimes even into the early spring.A The light box may be mounted upright to a wall or slanted downwards and set on a table.
The light from a slanted light box is designed to focus on the table upon which it sits, so patients may look down to read or enjoy other sedentary activities during their phototherapy sessions. Patients using an upright light box must face the light box, although they dona€™t need to look directly into the light. As for the brightness of the light utilized, the light sources in these light boxes typically range from 2,500 to 10,000 lux (units of illumination).
In comparison, average indoor lighting typically ranges from 300 to 500 lux, and a sunny summer day is roughly 100,000 lux.A Before undergoing any light therapy treatments for Seasonal Affective Disorder, be sure to discuss your concerns and options with a qualified health professional. If you believe that you suffer from SAD, it is vital that you receive a proper diagnosis from a physician experienced in treating mood disorders. As well, certain risks (like potential eye strain, hypomania and headache, among others) are associated with phototherapy, especially for people who are photosensitive, so consulting with your doctor and an ophthalmologist could prevent additional problems from arising during or after your treatments.
If you decide to pursue light therapy treatments without the assistance of a qualified health professional, be aware that different companies hold decidedly different stances on exactly what constitutes light therapy.
A Among the health-related companies that are now making light therapy part of their business are manufacturers and retailers of home saunas. It is a logical development since far infrared sauna therapy has repeatedly been proven to be an effective form of light therapy. The light found in a far infrared sauna is, of course, far infrared light, a type of invisible light located below the optical color red in the electromagnetic spectrum.A An indispensable part of life on Earth, far infrared light has long been used by humans to purify polluted air, keep newborn babies warm in hospitals, promote growth in plants, and more. Little did the early sauna bathers of Finland realize centuries ago that their beloved heat baths might someday become a source of hope and healing, not just for the people of their own country but for everyone who finds the dark days of winter hard to weather.A Sweat and Far Infrared Saunas- Here's the Skinnyby Pertti Olavi Jalasjaa For whatever reason, most people feel uncomfortable talking about perspiration.
For example, ita€™s not unusual to hear someone remark that he or she a€?sweateda€? over an academic assignment, a€?worked up a sweata€? on the tennis courts, or a€?lost a pint of sweata€? while awaiting an important decision.
But these are simply colloquial expressions that many of us utilize to make a point about our mental or physical stress or exertion related to a particular undertaking or event.
After all, to do so, polite society decrees, would be in poor taste.A And yet much could be gained if people felt free to discuss the natural biological process of perspiration without fear of judgment or reproach. When we perspire in a far infrared sauna, we help our bodies rid themselves of the countless toxins like mercury, lead, cadmium and other contaminants that have accumulated within us over time.
As well, by intensely sweating in a far infrared sauna we benefit our hearts, lungs, kidneys and other organs that are essential to our survival.
Far infrared sauna bathing has also been proven to promote pain relief, muscle relaxation, and emotional tranquility.A For people suffering from certain skin diseases, far infrared sauna bathing can be particularly therapeutic.
As the far infrared heat induces an increase in blood circulation to the skin, the bodya€™s defence against chronic skin conditions like acne, eczema and psoriasis is considerably bolstered.
As well, thorough sweating helps unclog the skin of whatever unhealthy remnants of soap, lotions, deodorants or makeup may be unnecessarily lodged in its pores.
Dead skin cells are also effectively flushed away by a good sweat in a far infrared sauna.A Increased blood flow and decreased toxins and foreign material in our skin mean more natural nutrients and fewer reasons for irritations and disease. Elasticity, texture, tone and color can all noticeably improve after just a few sessions in a far infrared sauna. These benefits are available even if your skin has suffered harsh damage from excessive exposure to the sun.A You dona€™t have to talk about perspiration if you dona€™t want to. If you live a mostly sedentary lifestyle and therefore dona€™t perspire much on a regular basis, you must take action for the sake of the health of your heart, lungs, skin and other vital organs. People face stress at home, at work, at school a€“ anywhere opportunities to react to internal or external stimulation exist.A That stimulation can come from a disagreement with a spouse, a conflict with a co-worker, criticism from a teacher, bad news from a doctor, and so on. And the stimulation need not be negative; people often become stressed when they start new jobs or enter into new relationships. Even a big, surprise win at the casino can cause stress.A A little stress isna€™t necessarily a bad thing.
Stress during a job interview can help you give the best answers to the people asking the tough questions. These hormones are not harmful in moderate amounts, but cortisol is secreted excessively in response to chronic stress and is extremely toxic in these larger amounts.A a€?Cortisol actually kills and disables your brain cells,a€? says Dr.
Chronic exposure to cortisol causes the mental haziness, forgetfulness and confusion that is associated with aging.a€?A People under stress may also be at higher risk of developing coronary heart disease.
Stress causes arteries to constrict and blood to become stickier, increase the probability of an artery-clogging blood clot.
As well, people who regularly experience sudden increases in blood pressure caused by stress may, over time, develop injuries in the inner lining of their blood vessels.A Studies suggest that chronic stress may increase a persona€™s chances for developing infections, having strokes, experiencing flare ups of multiple sclerosis, and suffering gastrointestinal problems like peptic ulcers, irritable bowel syndrome, and inflammatory bowel disease. Chronic stress has also been linked to the development of insulin resistance, a key factor in diabetes. And ask anybody who has ever suffered from headaches, insomnia, skin disorders or sexual dysfunction if they believe that stress was at least partly to blame for their woes, and then construct your own conclusions about how damaging stress can be to onea€™s health and well being.A If you think you have a serious condition that has been caused or made worse by certain stressors in your life, you should discuss your concerns with a qualified physician. If, however, youa€™d like to improve the quality of your life by learning how to better cope with stress, many options exist.
Perhaps your first focus should be on discovering the remarkable benefits of relaxation.Relaxation decreases blood pressure, respiration and pulse rates, releases muscle tension, and eases emotional strains.
In their quests for greater relaxation, some people choose biofeedback while others opt for massage therapy.
Studies indicate that soaking in a hot sauna bath can help improve respiratory function, increase cardiovascular strength, reduce and remove body toxins, strengthen the bodya€™s immune system, relieve headaches, and cleanse and beautify skin. Sauna bathing can also increase blood circulation, relaxing tight, tired or aching muscles by providing them with more oxygen.A If youa€™re searching for a healthy way to alleviate the stress in your life, consider purchasing a home sauna. Residential saunas are available in a range of styles and sizes, from pre-cut Finnish sauna kits to outdoor barrel saunas and far infrared heat therapy rooms. Seemingly ubiquitous advertisements and TV commercials for antiperspirants continue to convince generations of consumers that perspiration is an undesirable, offensive bodily function. While no one would dispute that sweat can be quite unwelcome in important social and business situations, it would be imprudent not to acknowledge the necessity of perspiration and understand the critical role it plays in human health.A Sweating is an essential function of the human body, as essential as eating, breathing and sleeping.
Skin is sometimes called a€?the third kidneya€? for this very reason.A Your body eliminates various toxins through a variety of metabolic processes, one being urination and another being perspiration.
The kidneys filter waste materials from the blood and excrete them, along with water, as urine. The temperature in a traditional Finnish sauna is usually between 180 and 200 degrees Fahrenheit (80 and 95 degrees Celsius). The two types of sauna operate differently, but, at their respective temperature ranges, working up a sufficient sweat in either type should be achievable for even the most inexperienced sauna bather.A Using high heat to induce perspiration has a great number of benefits. In addition to decreasing the amount of toxins and heavy metals, such as cadmium, lead, mercury, nickel and zinc, in your body, an intense sweat bath in a sauna can help cleanse it of other impurities like cholesterol, nicotine, sodium, and sulfuric acid.
By improving blood circulation, regular sauna bathing can help draw the skina€™s own natural nutrients to the surface, leading to better tone, texture and elasticity.
Thata€™s why sauna bathing is being increasingly included in high-intensity treatment programs for skin ailments like acne, eczema and psoriasis. Some beauty specialists in Europe even claim the sauna can be quite a powerful weapon in the war against cellulite.A As beneficial and therapeutic as sweating in a soothing hot sauna may be, however, it is imperative that bathers not allow the experience to dehydrate them. As well, be sure to discuss your plans and expectations with your personal physician before you take to the sauna for the first time, as he or she should know of any existing conditions or limitations that pertain specifically to your health and might impact your sauna use.A As for all those advertisements and TV commercials that say sweating is bad, forget about them, and start doing what you know is best for your health.
