Melatonin can improve sleep, shorten the time before bed awakening and sleep time, and improve the quality of sleep, the number of awakening during sleep is significantly reduced, the light sleeping phase is short, the deep sleep phase is prolonged, and the threshold of the wake -up in the morning the next morning decreases. Have a strong adjustment time difference function. Melatonin is mainly used to increase white moisturizing cosmetics and is also commonly used in raw products. At home and abroad, the biological functions of melatonin have been widely studied, especially the health care functions of dietary supplements, indicating that it has a number of physiological functions such as promoting sleep, regulating time difference, anti-aging, regulating immunity, and anti-tumor.
Freedom bases may be generated when the body's enzymatic reactions and non-enzymatic reactions, and free radicals are closely related to aging. The generation and elimination of free radicals in the normal body are dynamic balances. Once this balance is broken, the free radicals will cause biocarbon damage such as lipids, proteins, and nucleic acids, leading to damage to the cell structure and aging of the body. Melatonin removal of free radicals, antioxidant, and lipid peroxidation reactions to protect cell structure, prevent DNA damage, and reduce the content of peroxide in the body. Objective effects caused by melatonin caused by peroxidation caused by melatonin to exogenous poisons and tissue damage caused by the generated free radicals have obvious antagonistic effects.
Melatonin has obvious protective effects on the body's peripheral lymphocyte chromosomal damage caused by the γ -rays of 137CS, and it has a dose-effect relationship; it has antagonistic effects on physical and chemicals caused by free radicals. Melatonin can reduce the formation of DNA bonuses induced by a chemical carcinogen to prevent DNA damage. Melatonin promotes endogenous granular white blood cells/macrophages through bone marrow T-cells and can be used as an auxiliary treatment for tumors.
Melatonin can antagonize the effect of mouse stress immunosuppressive effects induced by mental factors (acute anxiety), as well as paralysis and death caused by infection factors. Melatonin has the function of activating human monocyte cells, inducing its cytotoxicity and IL-1 secretion.
