Sleep - A True Gem of Health

In 1960 more than 80% of the American population got more than 7 hours of sleep a night. Today, it's barely 60% and we are paying very dearly for it. The average American sleeps 1 to 2 hours less than he or she did 40 years ago. On the average, we also weigh more and lack of sleep is definitely a part of the problem.

How is this so? When we sleep only 5 to 6 hours a night it seems to boost our appetite for high carbohydrate snack foods which contribute to poor endocrine (hormone) function. The consumption of low-fiber carbohydrates causes huge shifts in blood sugar levels which can lead to insulin resistence and ultimately diabetes. And what causes these cravings in people who get little sleep is an abnormal balance of two hormones that control appetite called ghrelin and leptin. Ghrelin increases your appetite and leptin quells these cravings. According to Kristen Kuntson, M.D., at the University of Chicago school of medicine, when they conducted a laboratory study to check these hormone levels, they found more ghrelin and less leptin in individuals who slept for four hours compared with individuals who were allowed to sleep for nine. When the sleep deprived individuals were asked to assess their hunger levels, they reported higher levels and their snacks amounted to 200 calories more than the longer sleepers.

So what's the take home for the American population? More sleep is critically important for several aspects of health. Getting a minimum of 7 hours of sleep each night can prevent a whole cascade of ailments which stem from poor hormone function. Make this a commitment on the top of your list and see how great you will feel!
