Scientists explain the increased risk of obesity due to lack of sleep

A study conducted by Japanese scientists from Waseda University and the company Kao Corporation has established a link between sleep deprivation and risk of overweight.

Scientists came to the conclusion that people who don’t get enough sleep, reduces the amount of hormones that regulate appetite and energy that is spent during the day, remains unchanged. With increased appetite that leads to weight gain, reports RIA “Novosti” with reference to the newspaper Asahi Shimbun.

The study was conducted on nine healthy young men aged about 23 years. They were in a special room, where they measured the speed of metabolism. Experiment participants first three days slept for seven hours. Then the next three days, sleep time was reduced in half.

It was recorded that after three days of lack of sleep the number of hormones that regulate appetite, has decreased by 10% in comparison with that recorded in normal sleep mode. Hormone levels will be restored to normal after the subjects returned to normal sleep mode.

According to the National sleep Foundation, people who do not adhere to the norms of sleep, are at risk of developing cardiovascular disease regardless of age, weight, smoker status and physical fitness.
