What is Heat exhaustion?

Heat exhaustion is a pathological condition in which the body becomes excessively dehydrated and deficient in essential minerals as a result of prolonged exposure to high temperatures. The body increasingly loses its ability to cool itself by perspiration as the health circumstances worsen. This causes an increase in body temperature, which can lead to heat stroke and death. Heat exhaustion is also caused by severe dehydration as a result of the lack of a substantial amount of body water, and may result in electrolyte imbalance in certain instances.
