Higher Diabetes Risk With Too Much Or Little Sleep

Don't get too much or too little sleep.

The study, authored by James E. Gangwisch, PhD, of Columbia University in New York, explored the relationship between sleep duration and the diagnosis of diabetes over an eight-to-10-year follow-up period between 1982 and 1992 among 8,992 subjects who participated in the Epidemiologic Follow-Up Studies of the first National Health and Nutrition Examination Survey. The subjects’ ages ranged from 32 to 86 years.

According to the results, subjects who reported sleeping five or fewer hours and subjects who reported sleeping nine or more hours were significantly more likely to have incident diabetes over the follow-up period than were subjects who reported sleeping seven hours, even after adjusting for variables such as physical activity, depression, alcohol consumption, ethnicity, education, marital status, age, obesity and history of hypertension.

The effect of short sleep duration on diabetes incidence is likely to be related in part to the influence of short sleep duration upon body weight and hypertension, said Dr. Gangwisch. Experimental studies have shown sleep deprivation to decrease glucose tolerance and compromise insulin sensitivity by increasing sympathietic nervous system activity, raising evening cortisol levels and decreasing cerebral glucose utilization. The increased burden on the pancreas from insulin resistance can, over time, compromise â-cell function and lead to type two diabetes, warned Dr. Gangwisch.

Too little sleep accelerates your aging.

Knowledge about how to slow your aging only helps if you act on it. Anyone going to change their sleep habits as a result of reading this?

The health effects of getting too little sleep have already been well-documented. The more relevant news in this article is the danger of getting too much sleep:

In other words, people sleep too long if they are already suffering from a pre-existing malady: for example, if they are chronically fatigued or depressed. Otherwise, I don't think human beings are wont to over-sleep.

Indeed, if I recall, in the days before electricity was available, farmers would sleep soon after nightfall and wake at dawn. This meant that during the winter, when the days were shorter and the temperature outside freezing, farmers slept 9-10 hours each night. I doubt that they were developing type 2 diabetes from staying in bed during that time.
