Melatonin and sleep

The sleep Foundation article "Melatonin: Usage, Side Effects, and Safety" provides an in-depth look at melatonin, a hormone produced by the pineal gland that regulates sleep-wake cycles. It discusses melatonin's role in circadian rhythms and its use as a supplement to address sleep disorders like insomnia and jet lag. The article outlines appropriate dosages, potential side effects—including headaches, dizziness, and daytime drowsiness—and emphasizes the importance of consulting a healthcare provider before starting supplementation. Regarding brain health and cognitive performance, the article notes that melatonin's primary function is to regulate sleep, which is crucial for cognitive functions such as memory consolidation and maintaining attention. By improving sleep quality, melatonin indirectly supports these cognitive processes. However, the article does not provide specific evidence directly linking melatonin supplementation to enhanced cognitive performance.The sleep Foundation is a reputable source for sleep-related information, and the article offers a balanced view of melatonin's benefits and potential risks. It suggests that lifestyle changes, such as maintaining a consistent sleep schedule, creating a comfortable sleep environment, and limiting exposure to screens before bedtime, can improve sleep quality and, consequently, cognitive health. While melatonin supplements may aid sleep onset, they should be used under medical supervision, especially since the article does not present detailed evidence of direct cognitive benefits.
