The Research of Rest, by developmental molecular biologist Dr. John Medina, gives you the facts-and the prescription to sleep well-in his signature engaging style. Modified from Medina’s Brain Rules for Maturing Well:10 Principles for Staying Essential, Happy, and Sharp, in this section you’ll learn how the rest cycle is born of the constant stress between human hormones and human brain regions vying to maintain you awake, and hormones and brain regions trying to cause you to fall asleep. This is known as opponent-process about The Research of Sleep theory. Sleep, researchers are finding, does not have as much regarding energy restoration since it does with processing thoughts and eliminating toxins in the brain. As you grow older, your sleep cycle becomes even more fragmented, specially the area of the routine during which toxins are flushed from the brain. Accruing good sleep habits by middle age (a stable rest routine; simply no caffeine, alcohol, or nicotine six hours prior to going to rest) is the best way in order to avoid sleep-related cognitive decline in old age. You may already be experiencing the sometimes-unpleasant effects of growing older. Or you might be deeply concerned about all your family members who are. In any event, The Science of Sleep is definitely for you.
