Melatonin is a hormone produced by the brain’s pineal gland that controls the body’s internal clock, helping regulate the sleep-wake cycle by signaling when it’s time to feel sleepy or alert. 1
Melatonin supplements are commonly used to treat circadian rhythm disorders like delayed sleep phase syndrome, helping people fall asleep earlier and wake at a more desirable or consistent time each day. 2
Bright screens and LED lights emit blue light that suppresses melatonin production, delaying sleep onset and disturbing normal sleep cycles, making screen time before bed a significant barrier to quality rest. 3
Travelers frequently use melatonin to manage jet lag, as it helps reset the internal clock more quickly when crossing time zones, reducing fatigue and restoring natural sleep patterns after long flights.
Shift workers often struggle to sleep during the day due to light exposure and body clock misalignment; melatonin can help cue the body into a sleep state at non-traditional hours. 4
Melatonin also functions as a powerful antioxidant, neutralizing harmful free radicals in the body, which contributes to reduced cellular stress and protection against damage linked to inflammation and aging. 5
Scientific studies suggest melatonin supports immune health by modulating immune cell activity, enhancing the body’s nighttime repair functions, and helping the nervous system recover from stress or environmental pressure. 6
As humans age, melatonin production naturally declines, which may be partly responsible for sleep difficulties in older adults; supplementing melatonin can help restore better sleep duration and quality. 7
When used appropriately for short durations, melatonin is generally considered safe, with limited side effects like dizziness, mild headaches, or next-day grogginess, especially when used in low, regulated doses. 8
Melatonin is not a sedative or tranquilizer—it acts as a chronobiotic, meaning it shifts or aligns your internal biological clock, allowing natural sleepiness to occur at the correct time. 9
Taking melatonin around 30 to 60 minutes before bedtime helps reinforce the body’s nighttime cues, making it easier to fall asleep for individuals suffering from insomnia or irregular sleep schedules.
Melatonin works by binding to MT1 and MT2 receptors in the brain, which influence how quickly you fall asleep and how well your body regulates daily cycles like sleep and mood. 10
Several foods, including tart cherries, grapes, and walnuts, naturally contain melatonin or its precursors, and eating them in the evening may help support better sleep without the need for supplements. 11
Melatonin may contribute to stress relief by lowering cortisol, the primary stress hormone; lower cortisol levels help promote feelings of calmness and reduce anxiety that might otherwise disrupt sleep. 12
In cases of chronic or short-term insomnia, melatonin can reduce how long it takes to fall asleep, although its effectiveness varies depending on individual biology and the type of insomnia experienced. 13
Children with autism or ADHD may experience better sleep through supervised melatonin use, as these conditions often involve disrupted melatonin cycles; pediatric guidance ensures safe outcomes in such cases.
High doses of melatonin do not necessarily improve sleep more than lower ones and may increase the risk of side effects; starting with minimal amounts allows for safer experimentation and adjustment. 14
People with seasonal affective disorder (SAD) may benefit from melatonin’s effects on the body clock, as winter’s reduced daylight hours often cause disruptions in mood and sleep that melatonin can ease. 15
Darkness is essential for melatonin release; even dim artificial lights can reduce its production. Creating a dark, screen-free bedroom environment helps the body maintain its natural rhythm and promotes deeper rest. 16
Although melatonin is available over-the-counter in many countries, the quality and concentration of products vary widely; choosing a reputable brand ensures you receive a consistent, safe dose without unwanted fillers. 17
