“失眠睡不着吃片褪黑素就能解决”是真的吗？

Core Viewpoint - Melatonin is often perceived as a natural solution for insomnia, but its use carries significant health risks and is not a universal remedy for sleep disorders [2][6]. Group 1: Melatonin and Its Effects - Melatonin is a hormone secreted by the pineal gland, primarily increasing in production during the evening to promote sleep [4]. - Over-the-counter melatonin supplements are exogenous and act as "rhythm regulators," potentially effective for jet lag but not for insomnia caused by anxiety or other physical conditions [6]. - Long-term use of melatonin can suppress the body's natural production of the hormone, leading to rebound insomnia or dependency upon cessation [8]. Group 2: Risks of Self-Medication - Self-medicating with melatonin or combining it with other sleep aids, such as sedatives, can mask underlying conditions like depression or anxiety, delaying proper diagnosis and treatment [9]. - Anxiety and depression can exacerbate insomnia, and without addressing these root causes, sleep issues may persist, potentially leading to increased reliance on sleep medications [11]. Group 3: Recommendations for Sleep Improvement - For short-term insomnia, mild interventions like certain herbal supplements may be acceptable, but persistent symptoms lasting over two weeks should prompt a visit to a specialist for targeted treatment [12]. - A comprehensive approach to improving sleep includes timely medical consultation, adjustment of sleep habits, regular exercise, balanced diet, and emotional regulation [12][14].
