Quick Answer
Ignoring heat stroke symptoms while hiking can lead to severe brain damage, organ failure, and even death. Heat stroke can occur within 10-15 minutes of exposure to temperatures above 104°F (40°C) for someone who is not acclimated. It is essential to recognize and treat the symptoms promptly.
Warning Signs of Heat Stroke
Heat stroke symptoms include high body temperature (above 103°F/39.4°C), confusion, agitation, slurred speech, seizures, and loss of consciousness. If you notice any of these symptoms in yourself or a hiking partner, seek shade immediately and remove excess clothing. Use cool water or a cold compress to lower body temperature, but do not use ice.
Treatment and Prevention
The most effective way to prevent heat stroke is to stay hydrated by drinking plenty of water, at least 8-10 glasses per day. Avoid strenuous activities during the hottest part of the day (usually between 11 am and 3 pm) and take regular breaks in shaded areas. Wear lightweight, light-colored clothing that allows for airflow and helps to reflect the sun’s rays.
Recognizing Heat Stroke in Others
If you are with a group of hikers, designate someone to monitor the temperature and health of the group members. Use a thermometer to check body temperature regularly, especially in people who are not acclimated to the heat. If you are alone, use a mental or written checklist to track your own symptoms and take regular breaks to cool down.
