Know the Signs of Heat Exhaustion and How to Prevent It

With hotter days just around the corner and more time spent outdoors, it is important to know the signs of heat exhaustion and dehydration.

Common signs of heat exhaustion in both children and adults may include:

  • Heavy sweating
  • Muscle cramps
  • Nausea
  • Weakness
  • Lightheadedness
  • Irritability

Dehydration symptoms in both children and adults include the following:

  • Increased thirst
  • Dry mouth
  • Headache
  • Fatigue
  • Dizziness
  • Dark-colored urine

“Hot weather can affect anyone, especially young children, older adults, and those who spend extended time outdoors," said Samantha Pulliam, MBA, MSN, RN, Specialty Accreditation Director and Nurse Pediatric Care Coordinator at Stony Brook Southampton Hospital. "Drink water throughout the day, take breaks in the shade or air conditioning, and avoid waiting until you feel thirsty to hydrate. Taking these simple steps can help prevent heat-related illness before it starts.”

Additional Prevention Tips

Taking a few additional precautions can help keep you and your family safe during hot weather:

  • Wear lightweight, light-colored clothing and a wide-brimmed hat when outdoors.
  • Apply and reapply sunscreen as directed.
  • Avoid strenuous outdoor activities during the hottest parts of the day, typically between 10 am and 4 pm.
  • Never leave children, pets, or anyone else in a parked vehicle.
  • Check on older adults, young children, and others who may be more vulnerable to heat-related illness.

“If you begin to feel dizzy, weak, nauseated, or develop muscle cramps while in the heat, move to a cool place right away, drink cold water, and rest," advised Pulliam. "If symptoms worsen, don't improve after cooling down, or the person becomes confused or loses consciousness, seek emergency medical care immediately.”
