Quick Answer
When hiking in extreme heat, hikers must employ techniques to conserve energy, stay hydrated, and avoid heat-related illnesses. This includes seeking shade, wearing light-colored, loose-fitting clothing, and drinking at least one gallon of water per person per day. Additionally, hikers should be aware of the signs of heat illness and take action to prevent it.
Preparing for Extreme Heat
Before embarking on a hike in extreme heat, it’s essential to prepare. This includes planning your route to avoid hiking during the hottest part of the day (usually between 11am and 3pm) and choosing a trail with plenty of shade. Wear light-colored, loose-fitting clothing that allows for good airflow and helps to reflect the sun’s rays. A hat with a wide brim and sunglasses can also provide additional protection from the sun.
Staying Hydrated
Proper hydration is critical in extreme heat. Aim to drink at least one gallon of water per person per day, and make sure to drink small amounts regularly throughout the day rather than trying to guzzle a large amount at once. Avoid drinking hot beverages, as they can further dehydrate you. If you’re wearing wet clothing, try to dry it off as soon as possible, but if not, it’s better to wear it than to leave it on and risk dehydration.
Night Movement and Heat Illness Prevention
If you must hike during the hottest part of the day, try to schedule your return journey for the evening hours. This can provide some relief from the heat. Additionally, be aware of the signs of heat illness, which include headaches, nausea, dizziness, and fatigue. If you or a member of your group is experiencing any of these symptoms, seek shade immediately and start drinking cool water. If the symptoms persist, consider seeking medical attention as soon as possible.
