Melatonin works mainly to improve sleep; its side effect is that it may have some dependence after long-term use and may interfere with the normal sleep rhythm.
Melatonin is a hormone secreted by the pineal gland of the human body, which has the effect of maintaining circadian rhythm, improving sleep and helping to fall asleep, and can reduce the duration of light sleep and increase the duration of deep sleep, so that a person can better regain energy during sleep.
The side effects of melatonin are not known, but it is important to note that melatonin is only indicated for people with poor sleep. Melatonin is contraindicated in children and adolescents, pregnant and breastfeeding women, people with autoimmune diseases, and people with depressive psychosis.
In addition, long-term supplementation of melatonin in large quantities may produce drug dependence, that is, the quality of sleep will be worse after stopping melatonin, or interfere with the normal sleep rhythm.
Before taking melatonin, patients are recommended to go to the hospital for consultation, and the doctor will decide whether to take melatonin and the dosage according to the patient’s sleep condition.
