Some serious health risks appear for astronauts living on a lunar base or going on deep space missions.
A 2014 study on 12 astronauts found that the heart becomes 9.4 percent more spherical after long exposure to microgravity, or weightlessness, in space. The researchers need to devise exercise regimens to keep deep space astronauts safe from these effects. A new five-year study is also underway to determine if space may speed up the development of atherosclerosis in astronauts.
Although NASA conducted an anonymous health care survey on its astronauts and ultimately dismissed concerns about excessive drinking, allegations were made in 2007 that drunk NASA astronauts were permitted to fly on the space shuttle and a Russian Soyuz spacecraft in two separate incidents.
At that time, NASA’s policy prohibited drinking for 12 hours before astronauts flew training jets.
One retired astronaut, Mike Mullane, said some astronauts drink alcohol before a flight to dehydrate themselves and make the countdown to launch more comfortable on their bladders. A 10-year sleep study showed that astronauts don’t get enough sleep for weeks before and during their space missions. NASA schedules 8.5 hours of sleep each night for astronauts, but most only get around six hours during their missions.
Studies have shown that even one shuttle mission could cause a substantial temporary hearing loss and a smaller permanent hearing loss, usually at the higher frequencies involved in hearing speech. Besides the noise levels, other factors that may contribute to hearing loss in space include atmospheric contaminants, higher intracranial pressure, and greater carbon dioxide levels. In 2015, NASA will study how to prevent hearing loss during a one-year mission to the International Space Station with two crew members. For astronauts, the risk intensifies because microgravity also causes a decline in blood volume. At least 14 American astronauts developed kidney stones shortly after their missions ended. Scientists have been working on an ultrasound machine about the size of a desktop computer to detect kidney stones and push them out of the kidney with short bursts of sound waves.
Although we don’t know what effects dust from other planets or asteroids will have on our astronauts, we do know that moon dust caused some problems on their lunar missions.
The most dangerous effect may be on the lungs if the fine particulates of moon dust are inhaled. But researchers admit they can’t duplicate the conditions of the Moon for their tests.
If necessary, NASA will use newer kinds of radiation shielding, nutrition supplements, and medications to counteract these changes to the immune system. An extremely unusual and long absence of solar activity is causing dangerous radiation levels in space. The effects of this type of exposure range from radiation sickness to cancer and organ damage. One mission to Mars could expose an astronaut to two-thirds of his or her safe lifetime limit of radiation.
When simulating deep space conditions, scientists discovered that exposure to high-energy particles, even in low doses, caused rats to react more slowly and become distracted. Also, plastics and other lightweight materials may provide astronauts with more protection from radiation than aluminum currently does. Some astronauts have developed serious, permanent vision problems from their time in space. Doctors at the University of Texas performed brain scans on 27 astronauts who’d been in space for over a month.

Scientists believe this may be another effect of the rise of fluid that occurs in a person’s body in a weightless, or microgravity, environment. If the problem is caused by intracranial pressure, one possible solution is to create artificial gravity for about eight hours each day by spinning the spaceship while the astronauts sleep. Kidney Stones can be very painful and discomforting, however if you know its early warning signs you can get them treated sooner. A kidney stone is a crystalline mineral stone like material formed inside the kidney or the urinary tract.
While some kidney stones, also known as silent stones, may not have any signs or symptoms, you will be able to notice the early signs of the problem. Kidney stones can damage the small tubes that carry urine out of the body which may result in changes in the appearance or smell of urine. Kidney stones may cause infections, especially urinary tract infections that may be accompanied by symptoms of fever and fatigue. One of the most characteristic early warning signs of kidney stones is the presence of blood in urine.
If kidney stones have been inside the kidneys for quite some time, they will often cause symptoms of fever and chills. Though all possible measures have been taken to ensure accuracy, reliability, timeliness and authenticity of the information; Onlymyhealth assumes no liability for the same. Lord Rhyolith was like a dog chasing his own tail and probably one of the easier bosses we have dealt with.
We also partied with the loots of Beth'tilac, but Krylon wasn't around for the kill (something about a date? We have yet to douse the wings of the firebird Alysrazor, but it is a work in progress and we should have it in due time.
Many threaten the astronauts’ lives, and at least one may jeopardize all deep space missions for the foreseeable future. Certain people on Earth, such as those on bed rest or with heart failure, may also benefit from this kind of exercise.
This happened even though flight surgeons and other astronauts allegedly brought their safety concerns to local managers. On the Skylab 4 mission, astronauts got so testy with mission control that they turned off their radio and ignored NASA for a day. They also get less than 6.5 hours of sleep each night during the three months of training before a flight.
Crews aboard the Soviet Salyut 7 and the Russian Mir space stations also registered temporary and permanent hearing losses after they returned. But NASA developed ways to reduce the noise levels with acoustic padding for the walls and quieter fans, among other measures.
They want to see how much hearing they can preserve for these individuals and determine an acceptable risk for hearing loss.
But that risk is far greater for astronauts in space because bones demineralize in a weightless environment. And in 1982, one Soviet cosmonaut doubled over in excruciating pain for two days on the Salyut 7 space station while his crewmate watched helplessly. Extremely sharp-edged moon dust can harm the heart and lungs, with effects ranging from inflammation to a heightened risk of cancer.
In fact, it’s been known to wear through multiple layers on a boot of Kevlar-like material. For example, on Earth, the dust particles are no longer in a vacuum or exposed to radiation.

The immune systems of astronauts on lengthy missions seem to change while in space, turning a simple cold or the flu into a potentially serious health risk. But the functioning of the cells may be higher or lower than normal, confusing the immune system. These radiation levels will also reduce the number of allowable days behind the shielding of a spacecraft by 20 percent. If that’s true for astronauts, the researchers believe they can devise a biological marker to predict which astronauts will experience these effects.
In this case, the pressure seems to build inside the skull from the increased flow of cerebrospinal fluid into the head. They usually form when there is an excess of stone-forming substances in the urine or the volume of urine is low.
If the urination is also accompanied by pain you should consider visiting your doctor to get yourself checked for kidney stones.
People with kidney stones often find it difficult to sit for long and begin to prefer standing.
With time the stones will frequently cause UTIs which usually bring along fever and chills. If you have or suspect having any medical condition, kindly contact your professional health care provider. Researchers are now studying the potential effects of a longer, more stressful deep space mission to Mars.
Ultimately, they want to figure out how to minimize hearing loss over an astronaut’s lifetime, not just one mission. Before the Soviets were able to launch a rescue for what they thought was appendicitis, the cosmonaut passed a small stone in his urine. Lunar dust can also scratch the cornea of an astronaut’s eye, causing an especially serious emergency in space.
Only more studies conducted on the Moon, rather than in a lab, will give scientists the rest of the information they need about lunar dust toxicity.
When the immune cell function slacks off, dormant viruses in a human body can reactivate, though without symptoms of sickness. Of the 300 US astronauts examined since 1989, vision problems developed in 29 percent of those on two-week missions and a whopping 60 percent of those who spent several months on the International Space Station. When kidney stones move from the bladder into the urethra, they usually cause frequent and painful urination along with UTIs.
If you are experiencing sudden, severe abdominal or back pain, you should visit your doctor soon. Concentrating in the kidneys, these salts may form stones that range in size from microscopic to as big as a walnut. When the cell function goes into overdrive, the immune system overreacts, causing allergies and rashes.
Researchers don’t know if this effect will diminish or intensify for astronauts in space longer than six months. But it’s critical to find out before sending a crew on a Mars mission that could last at least one year. But it’s also possible for the kidney to stop working if a stone blocks the tube that drains the organ.
