One More Reason to Get a Good Night’s Sleep

The brain uses a quarter of the body’s entire energy supply, yet only accounts for about two percent of the body’s mass. So how does this unique organ receive and, perhaps more importantly, rid itself of vital nutrients? New research suggests it has to do with sleep.

  • The body’s natural production of melatonin is critical to healthy sleep. Exposure to what we consider normal levels of light in the evening and at night delay the production of melatonin by up to 3 hours and on average 1-1/2 hours in everyone leading to profound health consequences including poor sleep as the most immediately obvious one. Others include increased risk of breast cancer, cognition deficit, diabetes, obesity, immune deficiency, and serious or fatal accidents. Incandescent lighting does this. Light produced by most LEDs and CFLs is worse.
