NCT ID NCT07138443

First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time

Summary

This study tests whether a single 3mg dose of melatonin, a common sleep supplement, can reduce the body's physical reactions to mental stress. Healthy adults aged 18-70 will take either melatonin or a placebo before a stressful public-speaking task. Researchers will measure changes in heart rate, blood pressure, and skin temperature to see if melatonin helps keep these responses in check.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
a 3mg oral melatonin tablet
What this could lead to
If it works, this could point toward a simple, over-the-counter way to dampen the body's physical stress response.
What could go wrong
This is a very small, early-stage trial with only 16 people, so results may not apply broadly. Melatonin can cause drowsiness, and its effects on stress are not yet proven.
