Do you get Enough sleep? Girls are the worst offenders: Put down your phone

Are you scared? If you don't get enough rest and sleep, your body will change, so be careful.

What happens to your body when you don't get enough sleep? People who don't get enough sleep have thicker legs and arms, a study has found. A study in the international nutrition journal, Nutrients, found that where the "fat" grows, it is linked to sleep duration.

After accounting for sociodemographic characteristics, lifestyle, comorbidities and medications, people who sleep less than seven hours a day have higher fat mass indexes in the torso, arms, and legs than people who get seven to nine hours of sleep. But no difference was found when compared with those who slept more than nine hours a day.

For both sexes, the results were similar for sleep-deprived men and women, but the increased arm fat mass was only seen in sleep-deprived women.

In addition, among obese people, those who slept less than seven hours a day had higher fat mass indexes in both arms and legs than those who slept seven to nine hours a day, although no association was observed in nonobese people.

Lack of sleep, why can cause obesity? After a long period of sleep deprivation or staying up late, the body's ghrelin increases rapidly with energy expenditure, which tends to make people more likely to feel hungry and overeat.

At the same time, sleep for a long time, serum leptin (a hormone that can reduce appetite) and serum ghrelin (a hormone that promotes appetite) will gradually rise, leading to increased hunger and appetite, which can make people crave high-calorie food.

What should you not do before bed to get enough sleep? Don't overeat, be emotional, spend too much time with electronic devices, drink, smoke, etc.
