Question

Answer 1

Explanation:

Yes, we need energy when we sleep because even when we sleep, most of our organs have to keep working. For example, heart needs to pump blood, we keep breathing, filtration is kidneys, etc. ... Energy is needed for those activities. So we need energy even when we sleep.

Answer 2

Answer:

The brain itself burns glucose4 for energy, accounting for about 20% of the calories we consume while at rest. Sleep is a time for the body to repair and regenerate5. In order to do this more effectively, our body temperature drops, our breathing slows, and our metabolism lowers.
