Research on sleeping habits of people has shown that late sleeping time may lead to glucose intolerance and diabetes mellitus.
Experimenting with sleep hours and sleeping late in the night, these are the things that may have serious health repercussions, says a new study that was published in the new issue of Archives of Internal Medicine. For 722 men and 764 women in the age group of 53 to 93 years in the study, the mean sleep hours was 7 hours in the night , with 27% of the people sleeping for six hours or less in the nights. Compared to those who slept for five hours or less, people who slept for 7 hours or more had less risk of developing diabetes mellitus or glucose intolerance. One interesting result of the study was not only people who slept for 5 hours or less had a higher risk of diabetes and glucose intolerance, same was also true for people who slept for 9 hours or more.
Diabetes mellitus is a metabolic disorder that happens due to rising levels of sugar in the blood, and mostly is due to defects in insulin secretion, insulin function or both.
This may be the reason why often sleeping less is associated with high risk of cardiac arrest. The researchers feel that this probably also explains why doctors prescribe seven to eight hours of sleep in the night for maximum health benefits.
