Space:A Hostile environment
Radiation
can cause cancer
Space radiation can also cause radiation sickness, which makes you feel sick and tired all the time
A closed habitat
viruses or sicknesses have no place to go
because astronauts are in a stressful situation and their bodies change to adapt to space, they may be more likely to get sick.
No atmosphere
if no air pressure,a person can’t live for even 10 minutes
Spacesuits protect the body, and they also provide air and air pressure
Zero gravity
the station is moving very fast, so really, the astronauts are always falling
it leads to muscle loss because their bodies don’t need to work very hard.Astronauts can become thin and weak
they need to exercise for at least 90 minutes every day to stay strong and healthy.
Circadian Rhythm
on a spaceship, astronauts experience a sunrise or sunset every 45 minutes, making for a 90-minute day
This throws off the natural rhythms of the body, including periods of wakefulness and sleep
Covering windows and using special lighting can help
Extreme temperatures
When the Earth blocks the sun temperatures can drop hundreds of degrees below freezing
when the sun hits the spaceship, the temperatures can swing 500 degrees in the other direction
