Being an astronaut is no doubt an exciting life, but all of that flying and floating around in space takes its toll on the human body.

Being an astronaut is no doubt an exciting life, but all of that flying and floating around in space takes its toll on the human body.

Over the years, NASA has found that space travel can affect a person’s bones and muscles, and it may even heighten the risk for cancer and other serious illnesses.

Many of the problems are a result of spending extended periods of time in zero gravity environments.

Bones cease to produce the proteins that spur cell growth and replacement, resulting in effects much like those of osteoporosis.

Upon returning, astronauts remain less able to regenerate the necessary cells, making them more vulnerable to fractures.

The muscles are similarly significantly impacted, with shrinkage and weakening often occurring, which compromises space travelers’ strength and coordination.

Radiation exposure also presents a bevy of health problems.

On one end of the spectrum is a temporary bout of sickness and on the other, is an increase in the risk of developing cancer in the future.

The possibility that astronauts will eventually suffer from degenerative diseases and central nervous system issues are also escalated by the exposure.

NASA has put in place several means of prevention, including exercise regimens and carefully constructed nutrition plans.

The organization’s health experts have also called for measures that ensure improved sleep quality, early health issue detection, and ongoing regulation.
