Care For Your Sleep

Posts Tagged ‘sleep duration and BMI’

Do you want to shed some pounds? American scientists found a good and very pleasant way to reduce weight. This technique does not require making great efforts, spending money or starving. All you need to do is just have a good 8-hour-long sleep every day without exceptions. According to the results of a recent study carried out by the experts from the Department of Psychiatry and Behavioral Sciences at the University of Washington, Seattle,  there is a strong connection between the duration of sleep and our BMI (Body Mass Index).

Th researchers are convinced in the fact that the shorter you sleep duration, the higher risks of being overweight you have. At that, this relationship is valid even in those situations, when people who live in constant lack of sleep do great amounts of physical activities during the day. More than 1,1 million people participated in the experiments. A group of the scientists was observing the people with various duration of sleep and came to the conclusion that increased sleep is connected with increased level of energy expenditure and is proportional to decreased BMI.

Numerous tests showed that the people who sleep less than 7-8 hours a day suffer from a certain hormonal disbalances. In particular, they have lower levels of leptin, a peptide hormone responsible for our appetite, food intake and energy balance. The experiments proved that those people who have decreased sleep duration have up to 75% increased risk of having extra weight. This research became an important step in studying the connections between our sleep and the levels of our metabolic hormones. Unfortunately, this scientific field is currently developed quite poorly.
