NCT ID NCT07198334

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested whether taking a daily 5-minute bath in hot water (45°C) for two weeks could help healthy young adults adapt to heat. Researchers measured changes in body temperature, heart rate, and other signs of heat stress in 26 participants. The goal was to see if such a short, convenient routine could trigger the body's natural heat acclimation, potentially offering a time-saving alternative to longer heat exposure methods.

What this could mean

Active substance

Passive heat acclimation via whole-body immersion in 45°C water

What this could lead to

If successful, this could offer a quick and easy way for people to get used to hot environments, potentially benefiting athletes or workers in hot conditions.

What could go wrong

This is a small, early-stage study with only 26 healthy participants. The brief heat exposure may not produce lasting or meaningful heat adaptation, and results may not apply to older or less healthy individuals.
