The Heat Stress Estimator is a JavaScript Exercise, and though it has been tested, no guarantees regarding the accuracy of the calculations are made.

The estimator is offered as a guide for estimating potential heat stress, to increase awareness of the effects that heat and humidity may have upon humans. Please use it that way.

The Heat Stress Estimator is © 2003 and may not be distributed or reproduced. The formula used in the estimator was based on one developed by the El Paso National Weather Service, later modified by the Florida Department of Forestry. Other info used in the Estimator is based on The USA TODAY Weather Book by Jack Williams.
