Heat Exhaustion

heat exhaustion

Heat exhaustion isn’t just something that happens in one afternoon, it can occur after you've been exposed to hot and humid temperatures for several days. Some of the first signs are excessive thirst, weakness, and headache. These are all signs of dehydration in the body, if untreated salt depletion can occur. With that you may experience nausea and vomiting, muscle cramps, and even dizziness. If you or anyone you are with experience these symptoms, it’s best to head inside or at least to a shady area, drink plenty of water, and remove any unnecessary clothing or items such as binoculars, backpacks, or photo vest. If symptoms don’t subside with these adjustments, seek medical help. Heat exhaustion can progress to heat stroke, which can cause brain damage and even cause death. Recovery from heat exhaustion can take several days, so don’t overdo it too quickly. Even wildlife knows to rest in the hottest parts of the day.
