If you've ever pulled an all-nighter, or just stayed up too late or gotten up too early, you may have knocked off-kilter the relationship between insulin and sugar in your body. Even if you only did it once. One night of inadequate sleep can impair your ability to utilize insulin for processing of sugar. Blood sugar levels escalate, with adverse effects on arteries, eyes, heart, kidneys, nerves. In other words, not getting enough sleep increases the risk of type 2 diabetes.
The incidence of diabetes has been skyrocketing in recent years. There are approximately 180 million people who now have diabetes.
"A study by U.S. scientists published last year found that people who slept less than six hours a night were 4.5 times more likely to develop abnormal blood sugar readings in six years compared with those who slept longer."
The new research seems to show that insulin sensitivity is influenced by the amount of sleep that was had the night before.
