Quick Answer
Sandstorms and heat waves pose significant threats to desert survival, with sandstorms reducing visibility and making navigation difficult, while heat waves can cause dehydration and heat exhaustion. Both phenomena can be deadly if not managed properly.
Managing Visibility in Sandstorms
When sandstorms are approaching, quickly seek shelter in a building or a vehicle with a secure roof. If no shelter is available, dig a pit or create a trench in the sand to protect yourself from the wind and sand. Use a scarf or bandana to cover your face and mouth to prevent sand from entering your lungs. In extreme cases, put on a gas mask rated for particulate protection.
Preventing Dehydration in Heat Waves
Stay hydrated by drinking at least 8-10 glasses of water per day, and avoid consuming salty or caffeinated beverages that can exacerbate dehydration. Take regular breaks in shaded areas to cool down, and cover your head and neck with clothing to prevent direct sun exposure. If you have a solar still or a water filter, use them to purify water from questionable sources.
Staying Cool and Alert
To prevent heat exhaustion, limit physical activity to early morning and evening when the sun is not intense. Use light-colored, loose-fitting clothing to reflect the sun’s rays, and remove excess clothing to stay cool. Monitor your body temperature and watch for signs of heat exhaustion, such as dizziness, nausea, and headaches. If you experience any of these symptoms, seek shade immediately and rest for at least 30 minutes before resuming activity.
