Should I take melatonin for sleep?
Melatonin is a timing signal, not a sleeping pill. Small doses (0.3–1 mg) taken early evening help body-clock (circadian) problems like jet lag or delayed sleep phase; large doses at bedtime are usually unnecessary and can disrupt rhythm.
Melatonin is a hormone the brain releases in darkness to signal night. As a supplement, it works best as a circadian tool, not a sedative. Small doses (0.3–1 mg) taken a few hours before desired sleep help shift the clock — useful for jet lag, delayed sleep phase, and shift work. High-dose bedtime melatonin (3–10 mg) is popular but rarely needed and can leave next-day grogginess or paradoxically delay the clock. Most over-the-counter products in the US contain far more than labeled. For chronic insomnia, cognitive behavioral therapy (CBT-I) outperforms melatonin.
What is it?
Melatonin is produced by the pineal gland; supplements are a synthetic form.
Why it matters
Used correctly, it can gently reset a disrupted clock. Used incorrectly, it wastes money and can worsen sleep.
Persian tradition
Persian medicine encouraged darkness, calm, and warmth in the hours before sleep — the natural conditions for melatonin release.
Modern scientific evidence
Low-dose melatonin (0.3–0.5 mg) is as effective as higher doses for phase-shifting and has fewer side effects.
Melatonin modestly reduces sleep-onset latency (~7 minutes) — a small effect.
CBT-I is first-line for chronic insomnia and outperforms all medications long-term.
Where tradition and science agree
- Persian tradition and modern medicine agree that natural darkness and steady rhythm are the real basis of sleep.
Where they differ — honestly
- Modern medicine has isolated the hormone; tradition trusted the night.
Practical daily use
- For jet lag: 0.5 mg at the destination bedtime for 2–4 nights.
- For delayed sleep phase: 0.3–0.5 mg a few hours before desired sleep, with morning light.
- Avoid taking large doses nightly for years without guidance.
Safety
- Not for regular use in children without medical guidance.
- Avoid in pregnancy unless prescribed.
- Purity varies widely in supplements — choose reputable brands.

Questions people actually ask
Is more better?
No. Lower doses shift the clock as well as high ones and cause fewer side effects.
Is it addictive?
It is not physically addictive but can become a psychological crutch.
Does it help staying asleep?
Modestly; other approaches (temperature, sleep pressure, CBT-I) work better.

Companion explains
Melatonin is a whisper to your clock, not a hammer for sleep. Use it small, use it early, and let darkness do the rest.
