  • What is heat stroke?

    Heat stroke is a serious and potentially life-threatening condition that can occur when your body overheats. It is crucial to understand its causes, symptoms, treatment, and prevention to ensure your safety and well-being, especially during hot weather or intense physical activity. We are going to delve into the essential aspects of heat stroke, providing information that could come in handy while you’re out on your summer treks.

    What is Heat Stroke?

    Heat stroke, also known as sunstroke, is a severe heat-related illness that occurs when the body’s temperature regulation system fails, and the body temperature rises to dangerous levels, typically above 104°F (40°C). Unlike heat exhaustion, which is a milder form of heat-related illness, heat stroke requires immediate medical attention as it can cause damage to vital organs and even be fatal if not treated promptly.

    How Do You Get Heat Stroke?

    Heat stroke can occur due to various factors, including:

    • Prolonged Exposure to High Temperatures: Spending extended periods in hot environments, especially without adequate hydration, can lead to heat stroke.
    • Strenuous Physical Activity: Engaging in intense physical activities, such as running or hiking, in hot and humid conditions can increase the risk.
    • Dehydration: Inadequate fluid intake can impair the body’s ability to regulate temperature, making it more susceptible to heat stroke.
    • Lack of Acclimatization: Sudden exposure to high temperatures without allowing the body to acclimatize can greatly increase the risk.
    • Certain Medical Conditions and Medications: Some medical conditions, such as heart disease or obesity, and medications that affect the body’s ability to regulate temperature can increase the risk.

    What Are the Signs of Heat Stroke?

    Recognizing the signs of heat stroke is crucial for timely intervention. Common symptoms include:

    • High Body Temperature: A core body temperature of 104°F (40°C) or higher is a key indicator.
    • Altered Mental State: Confusion, agitation, slurred speech, irritability, delirium, seizures, and even coma can occur.
    • Hot, Dry Skin: Unlike heat exhaustion, where the skin may be moist, heat stroke often causes hot and dry skin due to the failure of the body’s sweating mechanism.
    • Rapid Heartbeat: An increased heart rate as the body tries to cool itself.
    • Nausea and Vomiting: Feeling nauseous or vomiting can be a sign of heat stroke.
    • Headache: A throbbing headache is a common symptom.
    • Dizziness and Fainting: Feeling lightheaded or fainting can occur.

    How to Treat Heat Stroke?

    Immediate medical attention is essential for treating heat stroke. While waiting for professional help, take the following steps to cool the affected person:

    • Move to a Cooler Environment: Get the person out of the sun and into a shaded or air-conditioned area.
    • Cool the Body: Use any available means to cool the person’s body. This can include:
      • Spraying or sponging the person with cool water.
      • Placing ice packs or cold, wet towels on the person’s neck, armpits, and groin.
      • Immersing the person in a cool bath or shower.
    • Hydrate: If the person is conscious and able to swallow, provide cool water or an electrolyte solution. Avoid sugary or alcoholic beverages.
    • Monitor Vital Signs: Keep a close watch on the person’s breathing, pulse, and level of consciousness until medical help arrives.

    How to Prevent Heat Stroke?

    Preventing heat stroke involves taking proactive measures to stay cool and hydrated, especially during hot weather or physical activities. Here are some key prevention tips:

    • Stay Hydrated: Drink plenty of fluids, especially water, throughout the day. Avoid caffeinated and alcoholic beverages as they can contribute to dehydration.

  • Hot Weather Hiking Safety Tips

    Sunny days are perfect for lacing up your boots and heading out in search of an alpine lake, a mountain summit, or a dramatic slot canyon. However, the combination of intense heat and prolonged sun exposure can turn your fun day into a painful and potentially dangerous experience if not managed properly. This guide aims to provide you with essential tips and strategies for a safe and enjoyable hiking experience in hot weather.

    Planning Tips for Hot-Weather Hiking

    When to Hike

    Avoid the Hottest Time of Day

    The hottest time of day is typically between noon and 3 p.m. On scorching days, it’s best to avoid this period altogether. Start your hike early in the morning and aim to finish by early afternoon, or begin your hike after 3 p.m. If you must hike during the hottest hours, plan your route to include shaded areas or bodies of water where you can cool off.

    Go for a Night Hike

    In extremely hot locales, daytime temperatures can be unbearable. Night hiking can offer a cooler alternative. For more information, check out to our article about night hiking.

    Where to Hike

    Stay in the Shade

    Choose hiking trails that keep you under the shade of trees or within steep canyon walls to avoid direct sun exposure.

    Hike Near Water

    If shade is scarce, opt for hikes near oceans, lakes, or rivers. The cool breeze from the water can be refreshing. Additionally, you can frequently dip your hat, shirt, or bandana in the water and drape them over your body to stay cool as the water evaporates.

    Clothing and Gear Tips for Hot-Weather Hiking

    Choose the Right Clothing

    • Light Colors

    Wear light-colored clothing that reflects the sun’s rays rather than absorbing them. Opt for shirts, shorts, and pants in white, tan, or khaki.

    • Loose, Breathable Clothing

    Lightweight, loose-fitting clothing made from materials like nylon and polyester will help your body regulate temperature.

    • Cotton Can Be OK

    While cotton has a bad reputation in the outdoors due to its moisture-absorbing properties, it can be beneficial in hot and dry conditions. The moisture can feel good against your skin and help cool you down as it evaporates. However, be cautious as wet cotton can cause chafing and discomfort.

    • Open Vents

    Some hiking clothes come with built-in vents. Opening these vents can improve airflow and help keep you cool.

    • UPF-Rated Clothing

    Clothing with a UPF rating provides guaranteed sun protection. Common ratings include UPF 15, UPF 30, and UPF 50+. Learn more in our Sun Protection Clothing Basics article.

    Cover Up

    • Hats

    A hat is essential for protecting your face and neck from the sun. A sun hat with a brim that goes all the way around is more effective than a baseball cap.

    • Cool Your Neck

    Use a bandana, sun-protective neck gaiter, or other lightweight cloth soaked in water to keep your neck cool. Special polymer-crystal filled neck scarves can maintain moisture for longer periods.

    • Wear the Right Socks

    Avoid cotton socks and choose wool or synthetic options instead. Ensure they fit well to prevent blisters and discomfort. You might have the right boots, but the right socks can actually make all the difference.


    Bring Enough Water

    Ensuring you have enough water is crucial for a summer hike in hot weather. Dehydration can set in quickly, especially when temperatures soar. As a general rule, aim to carry at least one liter of water per hour of hiking. This amount can vary depending on the intensity of the hike, the temperature, and your individual hydration needs.

    For longer hikes, consider carrying a hydration pack with a larger capacity, such as a 3-liter bladder, to minimize the need for frequent refills. Additionally, bring along a lightweight, portable water filter or purification tablets. This allows you to safely refill your water supply from natural sources like streams and lakes, which can be a lifesaver on extended hikes.

    Carry a Hydration Pack

    A hydration pack with a sip tube makes it easier to hydrate frequently compared to a water bottle. These packs are designed to hold a bladder that can carry anywhere from 1.5 to 3 liters of water, allowing you to stay hydrated for longer periods without the need for frequent refills.

    The sip tube, which extends from the bladder to your shoulder strap, provides hands-free access to water, making it convenient to drink while on the move without having to stop and dig out a water bottle from your backpack.

    Health Concerns for Hot-Weather Hiking


    Sun-protection clothing is a good defense, but don’t forget to apply sunscreen to exposed skin. Choose an SPF 30 or higher for hikes lasting longer than 2 hours. Apply sunscreen 15 minutes before sun exposure and reapply every 2 hours or after swimming or sweating. Learn more in our Sunscreen: How to Choose and Sunscreen: When and How to Use articles.


    Adequate hydration is crucial to prevent dehydration, which can lead to other heat-related illnesses. A good starting point is to drink about a half-liter of water per hour of moderate activity. Adjust this amount based on temperature, humidity, and your activity

    level. Remember that thirst is not always a reliable indicator of hydration status, so make it a habit to drink water regularly throughout your hike.

    Heat Exhaustion and Heat Stroke

    Recognizing Symptoms

    Heat exhaustion and heat stroke are serious conditions that can occur when your body overheats. Symptoms of heat exhaustion include heavy sweating, weakness, dizziness, nausea, and headache. Heat stroke is more severe and can be life-threatening, with symptoms such as high body temperature, confusion, rapid pulse, and unconsciousness.


    To prevent these conditions, take frequent breaks in the shade, drink plenty of water, and listen to your body. If you start feeling unwell, stop hiking, find a cool place to rest, and hydrate.
