The human body is great at cooling itself through natural mechanisms. Humans actually do it better than any other mammal on Earth. But extreme heat can overwhelm the body, resulting in heat-related illness.
Heat-related illness can include:
- Heat cramps
- Heat exhaustion
- Heat stroke
When you visit your National Forests and Grasslands, take the extra time to protect yourself and others from heat related illness.
- Drink plenty of water. Avoid sugary drinks and alcohol, as they can lead to dehydration.
- Stay in the shade whenever possible
- Schedule the most rigorous activities for early or later in the day
- Wear lightweight, loose-fitting, light-colored clothing
- Keep a close eye on older adults, children, and those with chronic medical conditions
- Heavy sweating
- Cold, pale, clammy skin
- Fast, weak pulse
- Nausea or vomiting
What to do:
- Move to a cooler location
- Lie down and loosen clothing
- Apply cool, wet cloths to as much of the body as possible
- Sip water
- If vomiting occurs and continues, seek medical attention immediately
