1, lack of sleep reduces the secretion of growth hormone. 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.

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 and increased fat synthesis.
