AIHA Releases Updated Heat Stress App for Indoor and Outdoor Workers

Posted on 5/12/2025 by Lion Technology Inc.

AIHA recently announced the release of Heat Stress App 2.0, a free mobile application to help indoor and outdoor workers monitor and stay aware of risk factors for heat stress in their workplace. Users of the app enter details about their work environment—heat, humidity, time of day, workload, location, etc. to calculate the user's risk factor for heat stress. 

The app provides users with resources about heat stress prevention measures, warning signs, and best practices for acclimating to heat in the workplace. The newly updated app considers factors like indoor temperature, relative humidity, non-solar heat irradiance, wind speed, workload intensity, and clothing worn by the indoor worker.
