Do you think you got enough sleep last week? Can you remember the last time you woke up without an alarm, feeling refreshed and not needy? Coffee? If the answer to any of these questions is "no", then you are not alone. Two-thirds of adults in all developed countries do not get the recommended eight hours of sleep. I doubt that this information surprised you, but you may be stunned by the consequences of such a total lack of sleep. A regular night's sleep of less than six or seven hours destroys your immune system, more than doubling your risk of cancer. Sleep deprivation is a key factor in determining whether you are at risk for Alzheimer's disease. Even a moderate lack of sleep during the week disrupts blood sugar so much that a person can be diagnosed prediabetes. Chronic sleep deprivation increases the chance of blockage and thinning of the coronary arteries, leading to cardiovascular disease, stroke, and congestive heart failure. According to the visionary wisdom of Charlotte Bront?, who said that "an indignant spirit always threatens with insomnia", sleep disturbances contribute to the development of all serious mental conditions, including depression, anxiety, and even suicidal tendencies. Have you also noticed that you want to eat more when you are tired? This is not a coincidence. Lack of sleep increases the concentration of the hormone responsible for feeling hungry, and at the same time suppresses the paired hormone that signals satiety. So it turns out that you are already full, but it seems that you want more - and this is the surest way to gain weight with a lack of sleep for both adults and children. If you try to go on a diet and you still don't get enough sleep, your attempt will most likely fail, since most of the weight loss will come from lean body mass, not fat.
