Sleep Aids
From melatonin and magnesium to prescription medications and sleep-promoting foods — an honest, evidence-based look at what works, what doesn't, and how to use sleep aids safely.
Navigating Sleep Aids: A Starting Point
The sleep aid market is enormous, crowded, and often misleading. Products range from well-researched supplements with good safety profiles to poorly studied remedies and medications with significant risks. Knowing the evidence — and the limits of the evidence — is essential for making informed decisions.
One important context: for chronic insomnia, no sleep aid — prescription or otherwise — outperforms cognitive behavioral therapy for insomnia (CBT-I) in the long run. CBT-I produces durable improvements without the tolerance, dependence, or side effects associated with medications. Sleep aids can play a role in short-term management, but they are rarely the right long-term solution for ongoing sleep problems.

If you're considering a sleep aid, first consider whether these foundational issues have been addressed:
- Sleep hygiene: Is your sleep schedule consistent? Is the room dark, cool, and quiet?
- Caffeine timing: Caffeine's half-life is 5-6 hours — coffee at 3pm may still be active at 9pm.
- Alcohol: Even moderate alcohol disrupts REM sleep and causes nighttime awakenings.
- Light exposure: Bright light (especially blue light) in the evening suppresses melatonin.
- Stress and anxiety: Unaddressed psychological hyperarousal is one of the most common drivers of insomnia.
No supplement compensates for poor sleep fundamentals. That said, some supplements and foods have genuine evidence for providing incremental benefit when fundamentals are in place.
