ATP and Sleep

Are you getting enough sleep? Rat studies, reported in the Journal of Neuroscience, showed that in the initial stages of sleep, energy levels increased dramatically in brain regions found to be active during waking hours. Adenosine triphosphate (ATP), the energy currency of cells, was found to surge during non-REM sleep. This surge of cellular energy may replenish brain processes needed to function normally while awake. Sleep appears to be necessary for this energy surge to occur.
