Melatonin Basics - What It Is, How It Supports Sleep, and How to Choose a Quality Supplement

Sleep Stress

Melatonin is a naturally occurring hormone your body releases at night to help signal that it is time to sleep. Modern habits - late screens, travel, shift work, stress - can throw this rhythm off, leaving you restless. Used thoughtfully, melatonin supplements may help you fall asleep faster, support a steadier sleep-wake cycle, and wake feeling more refreshed, without relying on habit-forming sleep aids or next-day grogginess.

What Melatonin Does

Melatonin helps your internal clock recognize night versus day. When evening approaches, your brain releases melatonin to nudge the body toward winding down. Light exposure, late meals, and irregular schedules can blunt that signal. A thoughtfully chosen melatonin supplement may help reinforce the body's natural timing in certain situations.

Dim bright lights and avoid screens close to bedtime to let melatonin work with your natural rhythm.
Keep a steady routine: consistent sleep and wake times improve results.

Modern Stress Has Changed

Over the past hundred years, the sources of stress and the ways we respond to them have changed dramatically. Once tied mainly to physical survival and daily labor, stress is now driven by technology, pace, and constant mental stimulation. By understanding how stress responses have evolved, we can regain practical tools to build resilience, protect metabolic health, and live with greater clarity and calm. See A Century of Stress to explore how modern stress affects sleep and what you can do about it.

Sleep as a Mental Health Tool

Quality sleep does more than restore energy. It helps regulate emotions, process stress, strengthen memory, and support clearer thinking. If you are building better sleep to improve mood, reduce anxiety, and stay resilient, see Sleep as a Mental Health Tool for practical guidance on how consistent, restorative rest supports long-term well-being.

Beyond Melatonin: Build Better Sleep from the Ground Up

Supplements support habits - they do not replace them. Better sleep sticks when you nourish your body with whole foods, move regularly, breathe with intention to manage stress, and think with clarity to keep routines on track. These Four Foundations help your nights and days work together.
