A chronic lack of sleep may cause far more serious problems than a tendency to nod off the next day. People who do not get enough sleep on a regular basis may become less sensitive to insulin which, over time, can raise the risk of obesity, high blood pressure and diabetes.

In fact, Dr. Eve Van Cauter at the University of Chicago found that chronic sleep deprivation--6.5 hours or less of sleep a night--had the same effect on insulin resistance as aging.

In Dr Cauters study, it was found that healthy adults who averaged 316 minutes of sleep a night--about 5.2 hours--over 8 consecutive nights secreted 50% more insulin than their more rested counterparts who averaged 477 minutes of sleep a night, or about 8 hours. As a result, "short sleepers'' were 40% less sensitive to insulin.

The researchers suggest that sleep deprivation, which is becoming commonplace in industrialized countries, may play a role in the current epidemic of type 2 diabetes. A poll by the National Sleep Foundation found a steady decline in the number of hours Americans sleep each night. In 1975, the average American slept 7.5 hours, down from 9 hours in 1910. Today, adults sleep about 7 hours a night.
