In Georgia's summer season, heat stress can cause problems for people, livestock and plants.
Dehydration is a main threat from heat stress.
An extreme form of heat exhaustion, heat stroke, can be fatal. To prevent dehydration, a person should drink plenty of fluids and take breaks often. A common heat stress index, called the heat index , was developed by R.G. Steadman in 1979. Use air temperature and relative humidity to determine the heat stress index below. There are other measures of heat stress but Steadman's heat stress index is a good composite of them all.
