How the Brain Heals: New Links Found Between Deep Sleep and the Prevention of Alzheimer's
The journalist, critic, and polemicist Christopher Hitchens, who amazed his friends by staying up until the wee hours of the night and then waking a few hours later to write pitch-perfect prose, said that he knew he burned the candle at both ends, “finding that it often gives a lovely light.” The problem is that, for most people, not sleeping can impair cognitive functions. Most of us can barely brew a pot of coffee without a solid six hours, much less write an essay on Proust. We all know that there is short-term damage done to our brains from lack of sleep, but recent studies have shown it could be far more damaging than that: lack of quality sleep might be a hidden cause of Alzheimer’s Disease and other forms of dementia.
