Melatonin: What You Need To Know

The National Center for Complementary and Integrative Health (NCCIH) article "Melatonin: What You Need To Know" provides an overview of melatonin, a hormone produced by the brain in response to darkness, which regulates sleep-wake cycles. The article discusses the use of melatonin supplements for conditions like jet lag, delayed sleep-wake phase disorder, certain sleep disorders in children, and pre- and post-surgical anxiety. It emphasizes that while melatonin can aid sleep, its effects on other bodily functions are not fully understood. Potential side effects include daytime drowsiness, headaches, dizziness, and nausea. The article advises consulting healthcare providers before use, especially for pregnant or breastfeeding individuals, and highlights that melatonin can interact with various medications.Regarding brain health and cognitive performance, the article does not provide specific evidence linking melatonin supplementation to cognitive enhancements. However, by promoting better sleep, melatonin may indirectly support cognitive functions such as memory consolidation and attention, as quality sleep is essential for these processes. The NCCIH, as a reputable institution, offers credible information, but the article lacks detailed evidence connecting melatonin use directly to improved cognitive performance.For lifestyle changes to enhance brain health, the article suggests maintaining good sleep hygiene practices: keeping a consistent sleep schedule, creating a dark and quiet sleep environment, and limiting exposure to light at night, particularly from screens. These practices can naturally boost melatonin production and improve sleep quality, thereby supporting cognitive function. While melatonin supplements may assist with sleep issues like jet lag or shift work disorder, they should be used under medical supervision, especially since the article does not provide comprehensive evidence of their direct benefits on brain health.
