"Our bodies use energy when we are sleeping for . . .

* Keeping our lungs going so we can still breathe.This of course, happens involunterly.

* Keeping our brains working.They send out all of the vital messages and make sure our organs keepoperating.

They will register pain and present images in our subconsious i.e. dreams.

* Maintaining body temperature.

* The digestion of food.

* Regeneration. While we don't require energy for other things,

the body will use it to heal injuries and refresh the body."

Yes, you use energy while you sleep - after all, you keep warm don't you. And your brain will use a little energy as well, as will the muscles for breathing, heart, arteries and so on. And tossing and turning.

When you are asleep, you body is still working, including the brain. It takes energy to maintain body temperature and operate muscles such as the heart. You may be asleep or unconscious, but your brain is still operation at nearly full capacity. It is communicating with all your organs. When you are dreaming in your sleep your brain is doing its thing and using energy to do it.

The basal metabolic rate reflects the requirement of a constant heart beat and rate of breathing. The BMR is an adaptation of all mammals and is directly correlated to the surface area to volume ratio. Another way to think of it is that there is an adaptive advantage to being able to quickly start moving from a state of rest. Just as a car with the motor running can go from stop to start when the light goes from red to green quickly and efficiently the body is capable of responding to quickly to the environment because we are not totally in a stupor at any time.
