EAT OFTEN & STAY HYDRATED – Eat more than you normally do, ensuring you eat before, during, and after your hike. No matter what the temperature, you need water and energy to keep going. Every hour hiking in the canyon can be likened to the physiological equivalent of shoveling wet sand. You need to eat about twice as much as you normally would to meet your energy needs while hiking in the heat of the Grand Canyon. Your best defense against illness and exhaustion is eating breakfast, consuming salty snacks, and alternating drinking water and electrolyte drinks throughout your hike.
STAY WET & COOL – Whenever you are near water, make sure you get your head and shirt wet to cool down. A wet bandana or sarong on the back of your neck can help lower your body temperature.
DO NOT HUFF & PUFF – Walking at a pace that allows you to walk and talk means that your legs and your body are getting the oxygen needed to function efficiently. At times it may seem like you are walking too slow (sometimes even baby-sized steps when the trail is steep), but your energy reserves will last longer. Take breaks and enjoy the view!
