Staying Safe Outdoors: How to Prevent Heat Illness

Heat IllnessHeat-related illnesses, such as heat cramps, heat exhaustion and heatstroke, occur when your body is unable to cool itself and are especially prevalent during the hot, summer months.

  • Heat cramps are painful contractions, commonly felt in the calves, thighs or shoulders, that occur as the body loses salt and water from exercise.
  • Heat exhaustion is a precursor to heat stroke and is brought on by a loss of water and electrolytes. The body will begin to sweat excessively and the core body temperature will elevate to more than 98.6 degrees Fahrenheit, but less than 104 degrees Fahrenheit.
  • Heatstroke occurs when the core body temperature is elevated to more than 104 degrees Fahrenheit. The body may stop sweating or sweat less and confusion or an altered mental status may occur.

Because heat-related illness can be very serious, and in some instances, lead to death; it is important to be aware of the signs and symptoms associated with these illnesses.

  • Symptoms of heat cramps are painful contractions.
  • Symptoms of heat exhaustion often include nausea, headache, fatigue and/or weakness, irritability, dizziness, confusion, thirst or signs of dehydration like a darkening of the urine.
  • Heatstroke often presents with symptoms of heat exhaustion, like head ache, confusion and weakness, accompanied by an altered mental status.

If you experience any of these symptoms, it’s important to call 911 right away to get quick medical attention.

Fortunately, these are preventable illnesses. During the summer heat, stay out of the sun, keep hydrated, watch for dark urine, avoid constrictive clothing and avoid drinking alcoholic beverages.
