SFD Warns: It’s Hot! Adjust Your Activity/Hiking Plan


With the jump in temperatures, Scottsdale Fire officials urge the public to adjust outdoor activities -- including hiking plans.

“Temperatures went from cool to hot in a matter of days,” says Scottsdale Fire Chief Tom Shannon. “That can be stunning to people who are used to being active outside – including hiking on our wonderful trails. However, when we get calls for mountain rescue late in the morning or early afternoon, that is a concern. If the person is injured, it can be compounded by heat-related illness.”

Individuals suffer heat-related illness when the body's temperature control system is overloaded, and the body can no longer cool itself. Call 911 if a person becomes confused, passes out from the heat or stops sweating.

It is important to know the early warning signs and take action. Heat cramps is the body’s way of saying “enough.” Go inside and drink room-temperature water. Avoid sugary drinks, caffeine, full-strength Gatorade and alcohol.

When a person is excessively sweating, has dizziness, headache, nausea/vomiting or feels weak, they are showing signs of heat exhaustion. If the person does not feel better 10-15 minutes after going inside and drinking water, call 911.

Preventing heat-related illness is key. “It is important to understand that heat will make trails more difficult, so choose your route wisely.  Get out early so you can get off the mountain before the heat of the day,” Shannon says. “Pre-hydrate days before your activity.  Bring plenty of water on the hike and carry a cell phone in case of an emergency.”

Common symptoms of a heat-related illness include:

  • Heavy sweating 
  • Paleness 
  • Headaches 
  • Nausea 
  • Dizziness 
  • Shallow breathing
  • Rapid but weakened pulse rate

If heat exhaustion is left untreated, it may progress to heat stroke, a severe form of heat illness.
