It is like a filing system, the
brain stores or discards what it
does or doesnt need. Also as soon as you fall asleep the
brain releases a chemical into your blood stream that tells the body to start repairing and healing all the little or big imperfections within you ie; cuts, infections, restoring and growing bone, making new cells etc etc..., and is the time that the body grows most. Sleep is essential for good health in both mind, body and spirit.
