An increasing number of patients with cases of heat stroke and dehydration mostly happen during the month of July and August every year.

The American College of Emergency Physicians provides suggestions on how to stay safe in hot weather:

  • Heat index checking before going out to work, play or practice and plan accordingly.
  • Try to avoid the direct sunlight in the middle of the day as much as possible. You can schedule your activities for early morning or early evening hours.
  • Wear loose, light-colored clothes and hats because the dark colors absorb the heat.
  • Drink lots of water or sports drinks, about 8 ounces an hour when in the sun in order to avoid dehydration.
  • Taking frequent breaks in the shade or in air-conditioning can cool you off.

You may calculate the “apparent temperature” before taking part in activities. According to the National Oceanic and Atmospheric Administration, At 90 degrees and 50 percent humidity, it feels like 96. While at 70 percent humidity, it feels like 106 degrees. Heat exhaustion is likely, so take it easy.

Heat exhaustion can include:

  • Cramps

  • Heavy sweating

  • Nausea

  • Heart-rate changes

  • Dizziness


You may want to get the victim out of the sun, remove excess clothing and place cool towels on extremities. Fan and give small sips of water.

It feels like 107 degrees for the 95 degrees and 50 percent humidity. When 70 percent humidity, it feels like 124 degrees. That temperature with any higher temperature or humidity, it is extremely dangerous to be outside, and heatstroke could occur.

Humidity ranging from 35-55 percent at 100 degrees can cause heat exhaustion. Then humidity of 60 percent or higher at 100 degrees puts a person into heat stroke territory.

And this explains how heat and high humidity is a dangerous combination.


Heatstroke is a medical emergency.


  • Confusion

  • An altered mental state

  • Unconsciousness

  • Hot, dry skin.


Do not give fluids, which can cause seizures and just call 911.
