Athlete deaths from heat exposure are on the rise.  Warming summers have been accompanied by weekly reports of athletes young and old collapsing from severe heat-induced illness. OSHA is campaigning to prevent heat illness in outdoor workers and reports that every year thousands of workers become sick working in the heat, and some even die.  In every instance, accurate and localized measurement of heat stress conditions is a key component of any heat illness prevention plan.

Human heat stress results from a combination of many environmental factors, air temperature and humidity along with radiant heat from the sun and surfaces, balanced by the cooling effect of breezes or air flow. Anyone who has stood under welcome shade adjacent to a sizzling parking lot understands that these conditions must be evaluated exactly where peoples' activities are taking place. The most common composite measurement used to determine appropriate exposure to heat stress conditions is Wet Bulb Globe Temperature or (WBGT) The American College of Sports Medicine, the American Conference of Governmental Industrial Hygienists have published threshold limit values (TLV's) or reference guidelines for conditions, activity levels and hydration based on WBGT, clothing levels and acclimatization of participants.
