Quick Answer
When overheating, rest is generally a better option than staying active, as it helps your body recover and cool down more efficiently.
Priority Cooling Over Hydration
When overheating, it’s essential to prioritize cooling over hydration. In a desert environment, for example, the priority rules are: 1) stop activity, 2) find or create shade, 3) cool down with water, and 4) hydrate. This order ensures that your body cools down and regulates its temperature before replenishing fluids. Aim to cool down for at least 30 minutes before rehydrating.
Rest and Rehydration Techniques
Rest in a shaded area, and use evaporation cooling techniques such as spraying water on clothing or using a wet bandana to lower your body temperature. Remove excess clothing and use a hat or umbrella to shield yourself from direct sunlight. When rehydrating, aim to drink 16-20 ounces of cool water per hour, taking in 4-6 ounces at a time to avoid overloading your stomach. Monitor your temperature and adjust your rehydration pace accordingly.
