How does leaving earth affect the human body?

you may feel muscels soreness pain on weak bones. You will feel space motion sickness like you would get sick on a boat. And also radiation because you will be pretty close to the sun thats why they made space suits for all of us.

when your in orbit for a long time things will happen to your body you will lose whight lose muscle and they have developed cancer once they come back we dont know why. So being weight less has a long term effect. So if your ill and you go to which will never happen they will never let a sick person go in to space.Because you will get worse. So going to space unhealthy is pretty bad.
