Summary

This trial will explore how work and rest times in hot environments affect the health and safety of workers, and how individual variation and next day effects should be considered.

Who is the study for?
This trial is for young (18-30 years) and older adults (50-69 years) who are generally active but not endurance-trained, do not smoke, and can understand English or French to give informed consent. It's designed to help workplaces manage the health and safety of workers in hot environments.
What is being tested?
The study tests how long people can safely work in heat before needing a break to avoid overheating. It will refine guidelines for initial stay times during moderate-intensity work in heat, considering individual variations and effects of rest periods like lunch breaks.
What are the potential side effects?
Since this trial involves simulated work in the heat, potential side effects may include symptoms related to heat stress such as increased core body temperature, fatigue, dehydration, dizziness or fainting.
