An American study found that people who sleep for an average of 5 hours a day gain more weight than those who sleep for 6 hours, and those who sleep for 6 hours gain more weight than those who sleep for 7 hours. In other words, the less sleep, the easier it is to get fat.

If a person sleeps less than 4 hours for two consecutive nights, the leptin level will decrease by 18% and the hunger hormone will increase by 20%. Leptin can inhibit appetite, reduce energy intake, increase energy consumption and inhibit fat synthesis. When leptin is lowered, it will make you fat.

In addition, sleep time at night is shortened, activities are increased, and the probability of eating extra food such as midnight snack is also increased. In the long run, the weight will naturally soar!

Then I don't get enough sleep at night. Can't you make it up during the day? No way!

If the sleep time is insufficient, the physiological function of sleep can not be fully exerted, and the damage is often systemic. For example, the incidence of endocrine disorders, gastrointestinal motility disorders and hypertension will increase. At the same time, lack of sleep will also reduce memory, accelerate brain damage, and even more serious, there will be critical situations such as sudden death.

Experts say that if you don't sleep well for only one night, a short sleep during the day the next day can quickly restore your energy and physical strength, but remember not to sleep too long, otherwise it will affect your sleep that night. However, if it is a long-term lack of sleep, daytime sleep can not completely repair the damage to the body.

In addition, experts also suggest that lack of sleep will also affect sexual interest.

So, friends: read more books, read more newspapers, eat less snacks and sleep more.
