Question #b522b

Your body NEVER stops "working" (or you're dead)! It may slow down some processes while sleeping, but it doesn't turn off.
Explanation:
Energy is required to sustain all of our living functions - heartbeat, breathing - even while asleep! Sleep gives particularly active muscles rest for recuperation (including our brains), but it does not stop all of the continuing necessary life processes, all of which require energy.
Because your body is still working.
Explanation:
When you sleep, it is a reasonable assumption to make that your body stops working, isn't it? After all, you don't think or feel anything, except for instances when you dream, right?
This view is false, as the body uses energy even while sleeping. That energy might be a minimal amount, but the truth is the body doesn't stop working until death, even if you are in a coma. The body still needs to supply oxygen to your bloodstream, still needs to produce new cells to replace dead ones made during the day, still needs to digest proteins and food from days ago, still needs to keep the heart beating, etc. Imagine if these activities stopped for the hours you went to sleep; If they did, you would never wake up.

Even your brain, the part of the body that should be resting, is never shut-off. It is still communicating sub-consciously through the nervous system, telling the cells and organs to do this or do that, and when we have vivid dreams it is almost as active as when we are awake.

Obviously, to do any of these things the body needs energy, so this is why energy is required when you sleep.
