Heat exhaustion can occur when you have inadequate or unbalanced replacement of fluids caused by physical exertion during high temperatures. Many hikers, backpackers, and climbers who are participating in activities in the desert, high temperatures, and high humidity levels will be more susceptible to heat exhaustion. When the body temperature increases and is unable to cool itself properly heat exhaustion can occur. The best way to keep from getting heat exhaustion is to stay hydrated and do not hike or climb during the hottest part of the day. Heat exhaustion is a step above dehydration, but less severe than heat stroke. Heat exhaustion can be easily treated as long as the symptoms are noticed early and treatment administered as soon as the symptoms begin. If they symptoms continue this can be a a sign of heat stroke. Learn how to spot and treat heat exhaustion.
