Sleep mode: The energy cost of sleep deprivation
Date:1/12/2011

zzle.

One question arising from the study concerns why humans don't conserve more energy during sleep. 'There are other functions of sleep that are important and cost energy,' explains Wright. 'Some conserved energy may be re-distributed to support vital physiological processes like learning and memory consolidation, immune function, and hormone synthesis and release.'

Wright is also quick to caution that energy expenditure during sleep deprivation is neither a safe nor effective strategy for weight loss as other studies have shown that chronic sleep deprivation is associated with impaired cognition and weight gain. He hopes recently initiated research in his lab will shed further light on this relationship and generate useful findings for 'at risk' members of the public.
