Quick Answer
To cool down during extreme heat on a hiking trip, try wearing light-colored, loose-fitting clothing, and stay hydrated by drinking water frequently. Wear a hat, sunglasses, and carry a personal misting bottle or a bandana soaked in water. Find shade when possible.
Staying Hydrated
Staying hydrated is essential in extreme heat. Drink at least one gallon (4 liters) of water per person per day. Aim to drink 8-10 ounces (0.2-0.3 liters) of water every 20 minutes. Monitor urine color to ensure it’s pale yellow or clear, as dark yellow or amber indicates dehydration. Avoid sugary drinks and caffeine that can exacerbate dehydration.
Cooling Methods
Several methods can help cool down in extreme heat. Wear a hat with a built-in brim or a neck gaiter to protect the neck from the sun. Use a personal misting bottle to spray water on the skin, which can lower body temperature faster than evaporation from clothing. Carry a bandana or a scarf to soak in water and wear it around the neck to stay cool. Avoid dark or heavy clothing that can trap heat.
Emergency Response
In extreme heat, it’s crucial to recognize the signs of heatstroke, which include dizziness, nausea, headaches, and confusion. If someone shows these symptoms, move them to a shaded area immediately and remove excess clothing. Fan them with a hat or a newspaper, and provide cool water to drink. Call for medical help if the person’s condition worsens or if they’re unresponsive. If you’re in a remote area, stay with the person until help arrives.
