IN THIS ARTICLE
The Heat Index estimates how warm it feels as a result of air temperature and relative humidity. Heat stress assesses the risk level of outdoor activities using the Heat Index. The stress thresholds allow users to track when heat stress will be experienced, and determine the duration and intensity of outdoor activities. Thresholds are region-dependent.
