Enhancing Natural Melatonin Levels: Techniques, Tips, and Additional Information
In the realm of health supplements, melatonin has been making waves due to its versatile benefits. A 2021 review reported that this hormone, primarily produced by the pineal gland in the brain, holds some efficacy for certain conditions, particularly hyperglycemia, preeclampsia, and intrauterine growth restriction during pregnancy. However, this article will focus on its more commonly known uses in treating sleep problems, migraines, and jet lag.
Melatonin's primary role is as a regulator of the body's circadian rhythm, the internal process that involves the sleep-wake cycle every 24 hours. This hormone plays a crucial part in signalling darkness, helping to regulate sleep patterns.
For sleep problems, particularly in individuals aged 55 and over, as well as in children, melatonin supplements can be beneficial. The hormone promotes the transition from wakefulness to sleep, making it an effective sleep aid.
In the realm of migraines, melatonin alleviates symptoms primarily by reducing neurogenic inflammation and restoring circadian regulation of immune responses. Clinically, melatonin supplementation can decrease monthly migraine days and has efficacy comparable to common migraine medications with fewer side effects.
Jet lag, a common problem for frequent travellers, can also be addressed with melatonin. By acting as a signal of darkness, melatonin helps reset the sleep-wake cycle disrupted by crossing multiple time zones. Low doses (around 0.5 mg to 5 mg) taken before bedtime at the destination improve sleep onset and quality. It works best for eastward travel across five or more time zones and is safe for occasional short-term use.
Preoperative anxiety is another area where melatonin shows promise. Its anxiolytic properties, partly by modulating central nervous system activity and neurotransmitters, can help reduce anxiety before surgery. However, this use is less extensively established than its role in sleep regulation.
Melatonin's multi-faceted actions—anti-inflammatory effects, circadian rhythm regulation, and nervous system modulation—underpin its benefits for migraines, jet lag, and preoperative anxiety.
While melatonin supplements are generally safe, potential side effects include feeling sleepy or tired in the daytime, headache, nausea, dizziness, irritability or restlessness, dry mouth, dry or itchy skin, pains in arms or legs, strange dreams or night sweats. In children, the side effects may include a risk of bedwetting, headaches, and dizziness, which usually resolve after stopping treatment.
Serious side effects of melatonin are rare and include blurry vision, eyes becoming more watery than usual, feeling faint or passing out, confusion or dizziness, vertigo, unexplained bruising, blood in the urine.
It's important to note that while melatonin supplements are widely available, the FDA does not approve melatonin for any use. However, melatonin receptor agonists such as ramelteon and tasimelteon are FDA-approved to treat sleep disorders such as insomnia.
In conclusion, melatonin, a naturally occurring hormone, offers a promising solution for various health issues beyond just sleep regulation. Its benefits for migraines, jet lag, and preoperative anxiety are backed by substantial evidence, making it a valuable addition to the arsenal of treatments for these conditions. However, as with any supplement, it's crucial to consult a healthcare provider before starting any new regimen.

- Melatonin's efficacy for migraines is substantiated by numerous studies, such as the one published in Cephalalgia in 2016, which reports a decrease in monthly migraine days with melatonin supplementation.
- In the review published in Sleep Med Rev in 2014, melatonin was found to improve sleep onset and quality during jet lag, particularly for eastward travel across five or more time zones.
- The neuroinflammatory effects, circadian rhythm regulation, and nervous system modulation of melatonin are highlighted in studies like the one published in Neuro Endocrinol Lett in 2015, which suggests a connection between melatonin and neuroinflammation in the pathogenesis of migraine.
- A systematic review published in Sleep Med Rev in 2013 concluded that melatonin can help manage jet lag, emphasizing its potential as a valuable tool for frequent travelers.
