With warm weather bearing down on much of the world due to rising temperatures and climate change, it's no wonder that meteorologists and physicians alike are often warning people about the danger of too much heat exposure. Precautions are taken to protect children, the elderly, and animals from the dangers of extreme weather. Exposure to excessive heat can cause heat exhaustion, which can lead to serious health concerns.


1. What is Heat Exhaustion?

Heat exhaustion is a series of symptoms caused by prolonged exposure to temperatures outside the body's comfort zone, usually during physical exertion. Heat exhaustion is one of three stages of heat illness: heat cramps, heat exhaustion, and finally heat stroke. Heat exhaustion can also happen when someone is not exercising but simply in high heat for a long period, such as during tanning or while gardening.
