Dehydration From Prolonged Heat Exposure


Hot weather can lead to an increase in your body’s core temperature.

This usually results in a higher sweat rate, leading to the loss of both fluid and electrolytes. The loss of fluid and electrolytes causes mild to moderate dehydration.

Engaging in physical work or endurance exercise in high heat presents even greater risks of dehydration.

Important Note: Dehydration is not the only heat-related condition. Heat illnesses can range from muscle cramps and heat exhaustion to heat stroke (which is a medical emergency). Common symptoms of heat illnesses include dizziness, nausea/vomiting, confusion, cramps, lethargy, and headache.
