Quick Answer
Staying cool in the desert requires a combination of proper clothing, hydration, and shade. Wear light-colored, loose-fitting clothes that allow for airflow, and bring a hat with a brim to shield your face and neck. Stay hydrated by drinking water every 20-30 minutes.
Staying Hydrated
To prevent dehydration, drink water at a rate of at least 1 liter for every 2 hours of walking. This may seem excessive, but it’s essential to replace lost fluids, especially in extreme heat. Avoid drinking cold water, as it can lead to stomach cramps and diarrhea. Instead, bring water in insulated containers and drink it at room temperature. Monitor your urine output to ensure you’re staying hydrated; if it’s dark yellow or amber-colored, drink more water.
Clothing for Cooling
Wear light-colored, loose-fitting clothes that allow for maximum airflow. A light-colored shirt can reflect up to 80% of the sun’s rays, while a loose-fitting shirt can allow for a 30-40% increase in airflow. Avoid dark or tight-fitting clothes, as they can absorb and retain heat. Bring a hat with a wide brim (at least 3 inches) to shield your face and neck from the sun. Consider wearing a scarf or bandana to cover your neck and face.
Shading and Rest
Take regular breaks to rest in shaded areas, ideally with a temperature 10-15 degrees cooler than the surrounding environment. Use a portable umbrella or canopy to create a shaded area, or look for natural shade under trees or rocks. During these breaks, remove excess clothing, wet a scarf or cloth, and place it on your neck or head to cool down. Avoid physical activity during the hottest part of the day (usually between 11am and 3pm) and plan your trek for early morning or late afternoon.
