What is heat exhaustion?

If you’ve ever felt faint in a hot yoga class or looking for shade because those sun rays are making your brain bubble, you’re somewhat familiar with overheating. While you might not clinically suffer from heat exhaustion, those are warning signs. “Becoming overheated simply means your body cannot cool itself off or return to its normal optimal temperature, which is usually around 98.6 degrees Fahrenheit for most individuals,” explains Roger E. Adams, PhD, CISSN, a doctor of nutrition and owner of EatRightFitness. “An overheated state is usually caused by exposure to extreme heat over an extended period. When your body temperature rises, blood flow to the surface of your body increases. Additionally, sweat rate and respiratory rates increase, in order to cool your body off. All of this creates an extra workload on the heart, increasing your heart rate.”

Why is heat exhaustion dangerous?

Heat exhaustion is risky because it’s a prelude to other sun-induced trouble. Adams explains that when you’re overheated, you sweat more, quickly causing you to be dehydrated as your body loses large amounts of water via your pores in an effort to regulate. (Psst: These are the signs of dehydration.) “Dehydration further places a strain on the heart, and since the heart is already working hard at pushing blood flow to the skin, this can lead to a dangerous situation for your heart,” he says. “An overheated state puts the body’s most vulnerable and delicate tissues at risk: nerve cells in the brain and throughout the body. This can lead to confusion, memory impairment, and even loss of consciousness.”
