Hiking in hot weather can be both challenging and dangerous if you're not properly prepared. Extreme heat can lead to dehydration, heat exhaustion, and even heatstroke, which can be life-threatening if not addressed quickly. Here’s a guide to help you stay safe and maintain your energy levels when hiking in extreme heat.
1. Know the Signs of Heat Exhaustion and Heatstroke
Understanding the symptoms of heat-related illnesses is critical for preventing serious health issues. Here’s what to watch for:
Heat Exhaustion:
-
Symptoms: Heavy sweating, weakness, dizziness, nausea, headache, and cool, moist skin.
-
What to Do: If you notice signs of heat exhaustion, immediately stop hiking, move to a shaded area, and drink water. Rest until symptoms improve.
Heatstroke:
-
Symptoms: High body temperature (above 104°F or 40°C), red, hot, dry skin, rapid pulse, confusion, dizziness, and loss of consciousness.
-
What to Do: Heatstroke is a medical emergency. If you suspect heatstroke, immediately call for help, move to a cool area, and try to cool the body with ice packs or cold water.
2. Stay Hydrated
Dehydration is one of the most common issues faced during hikes in extreme heat, and it can quickly lead to heat exhaustion or heatstroke.
-
Drink Water Regularly: Don’t wait until you're thirsty to drink water. Aim to drink small amounts of water every 15-30 minutes. A good rule of thumb is to consume about half a liter (17 oz.) per hour.
-
Electrolyte Drinks: In addition to water, consider drinking electrolyte drinks (such as sports drinks or hydration powders) to replenish lost salts and minerals due to sweating.
-
Avoid Alcohol and Caffeine: These can contribute to dehydration. Stick to water and drinks that help rehydrate your body.
3. Protect Yourself from the Sun
The sun can significantly increase the risk of heat-related illnesses, especially at high elevations or midday when the sun is strongest. Here’s how to protect yourself:
-
Wear a Wide-Brimmed Hat: A wide-brimmed hat or sun hat will provide shade to your face and neck, helping to keep you cool.
-
Use Sunscreen: Apply broad-spectrum sunscreen with an SPF of at least 30 to all exposed skin, and reapply every two hours, especially if you’re sweating or swimming.
-
Wear UV-Protective Clothing: Consider wearing lightweight, long-sleeve shirts, sun hoodies, and long pants made from UPF-rated fabrics that protect you from the sun while keeping you cool.
-
Seek Shade: Take breaks in the shade whenever possible to lower your body temperature and give your skin a rest from direct sunlight.
4. Adjust Your Hiking Schedule
When hiking in extreme heat, timing can be everything. Adjust your schedule to avoid hiking during the hottest parts of the day.
-
Hike Early or Late: The temperatures are cooler in the early morning and late afternoon. Start your hike at dawn and finish before noon, or begin in the late afternoon and hike into the evening.
-
Rest During Peak Heat: If you find yourself in the middle of the day with temperatures peaking, find a shaded area to rest and rehydrate. Avoid hiking during high noon, when the sun is at its strongest.
5. Wear the Right Clothing
Proper clothing can make a huge difference in how your body handles the heat.
-
Light and Breathable Fabrics: Wear light-colored, moisture-wicking clothing made of synthetic fabrics or merino wool. These fabrics help keep sweat off your skin and provide better ventilation.
-
Avoid Cotton: Cotton retains moisture and can make you feel hotter in the heat. Opt for performance fabrics that dry quickly.
-
Ventilated Shoes: Choose breathable trail shoes that allow air circulation around your feet. If possible, use shoes with open mesh sections to allow better airflow.
6. Take Frequent Breaks
Pushing through extreme heat can quickly wear you down. Take breaks to rest, cool down, and rehydrate.
-
Find Shade: Rest under trees or rock overhangs to avoid direct sunlight.
-
Stretch and Cool Down: During breaks, remove any extra layers, stretch your muscles, and cool your body down with water or a damp cloth.
-
Set Up a Water Station: If possible, rest near a stream or river to allow you to hydrate and cool off while taking a break.
7. Know When to Turn Back
If the heat becomes unbearable or you start feeling unwell, know when to call it quits.
-
Listen to Your Body: If you start experiencing dizziness, nausea, or fatigue, it’s time to rest or even turn back.
-
Turn Back Early: If conditions worsen and you feel your safety is at risk, don’t hesitate to turn back to the trailhead, especially if you’re far from water sources or help.
8. Crossing Water and Streams
Sometimes, crossing a stream or river is necessary to cool off during a hot hike.
-
Find Shallow Water: Look for shallow spots to cross where the current is gentle.
-
Remove Your Shoes: If the water is shallow and calm, remove your shoes and wade through the water to cool your feet and legs.
-
Take a Dip if Safe: If the weather is extreme and there’s a safe body of water nearby, take a quick dip to cool your body temperature down.
9. Use Cooling Products
If the heat becomes too much, consider using cooling products to help lower your body temperature.
-
Cooling Towels: A cooling towel or neck gaiter soaked in cold water can be draped around your neck to cool your body.
-
Portable Fans: Some hikers carry small, battery-operated fans to help keep cool while resting.
10. Watch for Dehydration
Dehydration is a major risk factor in extreme heat. Watch out for the following signs of dehydration:
-
Dry mouth or excessive thirst.
-
Dark yellow urine or infrequent urination.
-
Fatigue or dizziness: Feeling weak, lightheaded, or exhausted.
If you experience any of these symptoms, take action immediately by drinking water and resting in a shaded area.
