Summary

This trial aims to study the effectiveness of a 7-day passive heating protocol in older women to help them cope with indoor overheating. The study will involve warm-water immersion to see if it can reduce

Who is the study for?

This trial is for older females who may be vulnerable to heat-related issues due to lack of air-conditioning or reliable electricity. It's designed to help them become more resistant to heat by using warm-water baths. Participants should not have conditions that prevent them from safely experiencing increased temperatures.

What is being tested?

The study tests if soaking in warm water can make older women better at handling extreme indoor heat, without exercising. For seven days, they'll immerse in warm water with their core temperature maintained around 38.5°C for the last hour, and then face an 8-hour indoor heat challenge.

What are the potential side effects?

Potential side effects might include discomfort from prolonged warmth, dizziness or lightheadedness due to increased body temperature, and cardiovascular strain which could be risky for those with heart problems.

Experimental Treatment

Group I: Daylong exposure to indoor overheatingExperimental Treatment1 Intervention

Prior to and following the warm-water immersion protocol, participants will undergo a 10-hour passive heat exposure where they will remain in a climate-controlled chamber regulated at 36°C and 45% humidity (temperatures experienced indoors during extreme heat events in North America). During this time they will remain seated with the exception of hourly 5-minute breaks to stretch.
