With a constant lack of sleep increases when the body does not compensate for lack of sleep, the risk of obesity, heart disease and depression, scientists say. A previous study showed the relationship between sleep deprivation and obesity. In this study, researchers tried to find out which is the primary cause, obesity or lack of sleep. To understand how could the lack of sleep for a long time to problems with weight, the researchers analyzed data from more than 10 thousand British officials involved in the study. Scientists gave the first estimate of the health of men and women in the period of 1985 - 1988 years ago, when the participants are between 35 and 55 years were. This review was carried out every 2 years thereafter. In the period 1997-1999, the researchers analyzed the duration of sleep and obesity index in 5021 participants of the experiment. In assessing the scientists came to a consensus that people who sleep less than 5 hours a night, the risk of obesity increased by 65% compared with those who slept 7 hours. But when. The weight of the body weight and waist circumference measured again from 2003 to 2004 in 3786 men and women who are obese during the previous assessment, there was no significant association between sleep duration and obesity Given all of the studies, the researchers concluded that sleep deprivation may be a risk of being overweight, but not the rule.
