Does Melatonin Has Therapeutic Effect on Bad Sleep?
In recent years, many patients with insomnia have chosen to buy melatonin. What is melatonin? Can it be taken for a long time?
Melatonin is a hormone that regulates the biological clock in the human body. Under normal circumstances, the secretion of melatonin begins to increase at 8 o'clock in the evening, reaches a peak at around 2 o'clock in the morning, and gradually decreases after 4 o'clock in the morning, which has the function of helping the human body to adjust the circadian rhythm. In brief, when the secretion of melatonin in the body increases, it means that it is dark and it is time to sleep.
In vitro supplementation of melatonin is suitable for people with long-term night shift insomnia, jet lag and elderly patients with insomnia. If melatonin is taken in excessive amounts for a long time, it will affect the body's normal secretion of melatonin and cause sleep disorders.
He Ganchao, the chief physician of the First Ward of the Department of Brain Diseases of the First Affiliated Hospital of Guangxi University of Traditional Chinese Medicine, introduced that high-dose melatonin has side effects such as dizziness, headache, daytime sleepiness, and gastrointestinal discomfort. The impact on the brain is mainly reflected in the decline in memory, Inattention. Long-term use can also cause vasoconstriction, increasing the risk of stroke in the elderly, and adolescents can easily lead to precocious puberty. In addition, patients with liver and kidney dysfunction, pregnant women, and patients with cardiovascular and cerebrovascular diseases should be used with caution.
Long-term insomnia needs to find the cause and treat it symptomatically. Do not take melatonin blindly. To have a good quality of sleep, the most important thing is to develop regular work and rest habits.
