Quick Answer
In extreme heat, it's essential to stop and rest when your body temperature reaches 100.4°F (38°C) or when you experience symptoms such as dizziness, nausea, or headaches. If you're not in immediate danger, stop every 20-30 minutes to hydrate and cool down.
Recognizing Hyperthermia Warning Signs
Hyperthermia can sneak up on you, especially if you’re not paying attention to your body’s warning signs. Dizziness, nausea, and headaches are common indicators that your body is overheating. If you’re experiencing these symptoms, it’s crucial to stop and rest immediately. Additionally, be aware of other warning signs such as rapid pulse, flushed skin, and muscle cramps.
Stopping to Rest and Rehydrate
When you stop to rest, find shade or create your own if possible. Remove excess clothing, especially if it’s dark or heavy. Drink at least 16-20 ounces of cool water within 20-30 minutes to replenish lost fluids. If you’re unable to drink due to nausea or vomiting, try sipping small amounts of water every few minutes to gradually rebuild your hydration levels.
Creating a Cooling Environment
If you’re unable to find shade, create a makeshift shelter using a space blanket or a lightweight tarp. Weigh down the edges with rocks or branches to prevent wind from blowing it away. If you have a portable fan, use it to circulate air and speed up cooling. Avoid using ice or cold packs directly on your skin, as this can cause further heat loss and potentially lead to hypothermia.
