Identification of Critical Thermal Environments for Aged Adults

• Status: Recruiting
• Trial end date: 2025-02-28
• Target enrollment: 0
• Participant gender: All

Summary

This study evaluates critical environmental limits (temperature and humidity) above which older adults are unable to effectively thermoregulate. Participants will exercise in a series of different environmental conditions to identify combinations of temperature and humidity above which age-related physiological changes cause uncompensable heat stress, resulting in increased risk of heat illness.

• Phase: Phase 4
