    Do you think you got enough sleep this past week? Can you recall the last time you woke up without an alarm clock feeling refreshed, not needing caffeine ? 1.. Two-thirds of adults throughout all developed nations fail to obtain the recommended eight hours of nightly sleep.

2.. Routinely, sleeping less than six or seven hours a night destroys your immune system, more than doubling your risk of cancer. Insufficient sleep is a key lifestyle factor determining whether or not you will develop Alzheimer’ s disease. Inadequate sleep, even moderate reductions for just one week, disrupts blood sugar levels so profoundly that you would be classified as pre-diabetic.

Perhaps you have also noticed a desire to eat more when you’re tired? 3.. Too little sleep increases- concentrations of a hormone that makes you feel hungry while stopping a companion hormone that otherwise signals food satisfaction. Despite being full, you still want to eat more. It's a proven recipe for weight gain in sleep-deficient adults and children alike. Worse, 4., it is in vain, since most of the weight you lose will come from lean body mass(丢脂体重), not fat.

Add the above health consequences up, and a proven link becomes easier to accept: the shorter your sleep, the shorter your life will be. The old maxim “I’ll sleep when I m dead” is therefore unfortunate. Adopt this mindset, and you will be dead sooner and the quality of that (shorter) life will be worse. 5..
