The temperatures this summer have been extremely hot – and heat exhaustion/heat stroke have been increasingly common problems. Heat exhaustion can occur if the body loses an excess amount of fluid through sweating and does not have it replenished. When left untreated, heat exhaustion may progress to heat stroke, a life-threatening condition. At this stage, your body temperature rises to a dangerous level and the body may no longer sweat due to extreme dehydration. A person suffering from heat stroke may be in a state of confusion and disorientation. If you suspect someone is experiencing a heat stroke, call 911 immediately and apply cold compresses on the body to lower body temperature quickly.
