Exercise in Heat and Humidity

When summer hits and the heat and humidity is high you need to take special precautions. Drink plenty of water, more than normal.  Also change the time you exercise to a time of the day so it’s not so hot and humid.  Exercising in the heat and humidity takes your exercising to a whole new level.

Under normal conditions, body adjust to the heat. But these natural cooling systems may fail if you’re exposed to high temperatures and humidity for too long. If you sweat heavily and you don’t drink enough fluids you are at risk for a heat-related illness. Heat-related illnesses start out mild but worsening if left untreated. Heat illnesses include:

  • Heat cramps. Heat cramps are painful muscle contractions, mainly affecting the calves, quadriceps and abdominals. Affected muscles may feel firm to the touch. Your body temperature may be normal.
  • Heat exhaustion. With heat exhaustion, your body temperature rises as high as 104 F (40 C) and you may experience nausea, vomiting, headache, fainting, weakness and cold, clammy skin. If left untreated, this can lead to heatstroke.
  • Heatstroke. Heatstroke is a life-threatening emergency condition that occurs when your body temperature is greater than 104 F (40 C). Your skin may be hot, but your body may stop sweating to help cool itself. You may develop confusion and irritability. You need immediate medical attention to prevent brain damage, organ failure or even death.
