Heat-related illnesses can happen when a person’s body is unable to cool itself as normal during hot summer temperatures, according to the Centers for Disease Control and Prevention. Symptoms of heat stroke are an extremely high body temperature, dizziness, a rapid pulse, no sweating and a throbbing headache. It can lead to death or permanent disability.

Hot temperatures can also cause heat exhaustion, cramps and a rash.

Those most vulnerable to high heat are older adults, infants and children, athletes and people who work outdoors.

Pets also can be susceptible to hot temperatures and humidity, according to The Humane Society of the United States. They should not be left alone in vehicles or exercise during times of high temperatures.
