Heat Exhaustion and Heat Stroke

Heat exhaustion and heat stroke are heat-related health issues that may affect hunters.

Heat Exhaustion

Heat exhaustion is the opposite of hypothermia—the core body temperature increases, usually as a result of hot and humid conditions, plus a lack of water.

Prevention of Heat Exhaustion

  • Drink plenty of water.
  • Take frequent breaks if you’re hiking to or from your hunting spot, especially when carrying a large load.
  • Dress in layers, and shed layers as physical activity increases.

Symptoms of Heat Exhaustion

  • Pale and clammy skin
  • Dry mouth
  • Fatigue
  • Weakness
  • Dizziness
  • Nausea
  • Headache
  • Muscle cramps

Treatment of Heat Exhaustion

  • Move the victim to a cooler place.
  • Have the victim drink water or sports drinks.
  • Keep the victim inactive.
  • Fan to lower body temperature, but don’t over-chill.
  • In severe cases, seek medical attention.

Heat Stroke

Heat stroke should be treated as a medical emergency—it can be fatal.

Symptoms of Heat Stroke

  • Dry, hot, and flushed skin—dark or purple in color
  • Dilated pupils
  • Rapid, weak pulse
  • Shallow breathing
  • High temperature—may be in excess of 106° Fahrenheit

Treatment of Heat Stroke

  • Wrap in a sheet and soak with cool—not cold—water.
  • Fan, but don't over-chill.
  • Get to a hospital immediately.
