Beat the heat
Experts warn residents to be “heat smart.” Some things you can do to help beat the heat are:
Limit strenuous outdoor activities
Don’t leave kids or pets in a closed car
Drink more water
Drink less caffeine and alcohol
Check on senior friends and neighbors
Take frequent breaks
Get medical help if you stop sweating
Adults should take corrective action, and children should seek help, if they feel nauseous, their face feels like it’s burning or they have muscle cramps
Make sure outdoor pets have ample shade and water
The Centers for Disease Control and Prevention has specific recommendations for the symptoms of heat exhaustion and the even-more-serious heat stroke.
Nausea or vomiting
Cold, pale, clammy skin
“Heat exhaustion is on the milder side; that’s when you first feel that you’re dehydrated, you’re sweating a lot, you’re nauseous,” said Dr. Eric Shobitz, a pediatric emergency doctor at Adventist HealthCare Shady Grove Medical Center.
Under those circumstances, you should move to a cooler location, loosen your clothes, lie down, apply wet, cool cloth to as much of your body as possible and sip water. If you continue to vomit, seek medical help right away.
“Especially for kids, cooling off with a swim is helpful, but still [you still have to] take safety measures to stay cool,” said Dr. Shobitz.
“It’s good to be in the water but I would say make sure you keep your hydration going and be somewhere where it’s safe, where there are lifeguards watching the children,” he added.
