What will happen if you never leave your bed
NASA wanted to study the effects of microgravity on the human body and paid a guy to lie in bed for 70 days. So what would happen if you never left your bed? Firstly, you will start to develop bedsores. After that your bones and muscles will lose around 40-70% of their mass. Your heart rate will increase, but blood volume will decrease. Because of this, less oxygen will be taken up by your cells, and you’ll get tired much more easily. There is also an increased risk of kidney stones and pneumonia.
So we all should definitely spend a limited time in bed.
