People are always lack of sleep will face greater consequences than fatigue and concentrate hard. According to the study, poor sleep habits in the long run increase the risk of obesity and type 2 diabetes.
Scientists investigating the reasons behind the increased risk. Some research suggests that our sleep patterns affect blood sugar levels, a hormone that controls appetite, and even the brain's perception of high-calorie foods.
A small-scale study published in the journal The Annals of Internal Medicine, adds to evidence, particularly at the cellular level. Lack of sleep apparently reduces the ability of fat cells to respond to insulin, the hormone that regulates metabolism and plays a major role in diabetes.
In the study the participants were asked to sleep 8 nights in a sleep laboratory. During the first 4 nights they sleep normal hours, and 4 hours of sleep the next night they were only limited to 4.5 hours.
Apparently, after 4 nights of sleep deprivation, insulin sensitivity fell 16 percent respondents. Furthermore, the insulin sensitivity of fat cells down to 30 percent at those experienced by the obese or diabetic.
"Fat cells require sleep, and if hours of sleep deprivation is metabolically they will be disturbed," said Matthew Brady, a senior researcher.
When insulin resistance that had temporarily become frequent, the excess blood sugar and cholesterol will accumulate in the bloodstream, triggering heart disease and diabetes.
Brady said it is not known how the fat cells to recognize when we are sleep deprived. Probably due to lack of sleep will give your body's stress response, causing the release of the stress hormone cortisol and neropinehrine, associated with insulin resistance.
