how does sleep heal the body when you feel bad?


For example when you are sick, you’re told to rest. In some cases, one good nights rest can heal up many symptoms

In: Biology

It’s not that the rest itself helps you, it’s that you’re not putting extra exertion on your body when you’re sick. Your body is constantly busy renewing everything, clearing out sick and infection and waste all the time, usually most of your energy goes toward running your body normally.

When you become sick, your body tries to redirect resources to fighting off the uncontained infection. If you split those resources by not resting, you heal less quickly, and maybe not properly.
