Melatonin is an indispensable natural hormone in human body. It controls and affects the secretion of other different hormones. When melatonin in the body decreases, various functions of the human body will be affected, and various diseases will follow. Research shows that the secretion of melatonin begins to decrease after middle age, and its secretion is insignificant in old age. Early intake and supplementation of sufficient melatonin can improve the function of endocrine system, improve immunity, improve anti tension and anti-oxidation function, improve sleep, slow down the aging speed of human body and slow down the degradation speed of sexual organs; Melatonin can also help prevent and treat cancer, especially for habitual insomnia.
Melatonin can regulate the immune system. Neuroendocrine and immune system are interrelated. The immune system and its products can change the function of neuroendocrine. Neuroendocrine signals also affect the immune function. In recent ten years, the regulatory effect of melatonin on the immune system has attracted widespread attention. Studies at home and abroad have shown that melatonin not only affects the growth and development of immune organs, but also regulates humoral immunity, cellular immunity and cytokines. For example, melatonin can regulate cellular and humoral immunity, as well as the activities of a variety of cytokines.
Melatonin can adjust the circadian rhythm, and the secretion of melatonin has a circadian rhythm. After nightfall, the light stimulation decreases, the enzyme activity of melatonin synthesis in the pineal gland increases, and the secretion level of melatonin in the body increases accordingly, reaching a peak at 2-3 a.m. the level of melatonin at night directly affects the quality of sleep, but with the increase of age, the pineal gland shrinks until calcification, Cause the rhythm of the biological clock to weaken or disappear. Therefore, supplementing melatonin from outside the body can maintain the melatonin level in the body in a young state, adjust and restore the circadian rhythm, not only deepen sleep and improve sleep quality, but also improve the functional state of the whole body, improve the quality of life and delay the process of aging.
Melatonin also regulates the human respiratory system, digestive system and urinary system. In addition, melatonin has strong neuroendocrine immunomodulatory activity and free radical scavenging antioxidant ability, which may become a new method and way of antiviral treatment.
