1, lack of sleep reduces the secretion of growth hormone. Generally speaking, growth hormone, which will affect human metabolic rate, is secreted in large quantities at night 1 1- 1. Staying up late will reduce hormone secretion, which in turn will affect the basal metabolic rate. The basal metabolic rate decreases, and the excess calories after eating are easily converted into fat and accumulated in the body.

2. Lack of sleep inhibits leptin secretion. Leptin is a natural protein hormone, which can inhibit appetite, increase capacity consumption, inhibit fat synthesis, and of course is more conducive to weight control. However, when sleep time is insufficient, it will not only inhibit leptin secretion, but also increase the production of auxin.

In the state of leptin deficiency, it will be particularly difficult to resist high-sugar foods that are easy to gain weight. Studies have shown that people who don't get enough sleep consume an average of 350 to 500 calories a day, gain 1 kg in about 20 days, and gain nearly 20 kg a year.

3. Lack of sleep will increase physical stress. Long-term lack of sleep will lead to an increase in physiological stress, which in turn will lead to chronic inflammatory reactions in the body. If the body starts the protection mechanism, it will begin to accumulate water to store energy, leading to edema, increased fat synthesis and, of course, increased weight.

Extended data:

Solution: Proper sleep contributes to health. The best solution is to increase aerobic exercise for more than 30 minutes every day, which can effectively improve the basic consumption rate and cheer up the body from the inside out. Friends who don't get enough sleep should pay attention to going to bed early and getting up early, and try not to stay up late. If they stay up late, they should try to catch up on their sleep during the debris time.

In addition, during sleep, metabolites are removed from the extracellular space and do not accumulate in the brain. Therefore, a good sleep can promote the elimination of metabolic products such as dementia protein and have an important protective effect on cognitive function.
