Stay Safe in the Summer Heat: Prevent Heat Stroke and Dehydration

Summer is a great time to enjoy the outdoors, but high temperatures and humidity can increase the risk of dehydration and heat-related illnesses. Knowing the warning signs and taking simple precautions can help keep you safe.

"Many people don't realize how quickly dehydration and heat-related illnesses can develop, especially during periods of extreme heat," said Bayhealth Medical Director, Occupational Health and Walk-in Parvathi (Soma) Somasundaram, MD, MPH. "Staying hydrated and taking breaks from the sun can go a long way toward preventing serious health issues such as acute kidney injury and loss of consciousness."

Know the Signs

Common symptoms of dehydration include:

• Thirst
• Dry mouth
• Headache
• Dizziness
• Fatigue
• Dark-colored urine

Heat stroke is a medical emergency. Symptoms may include:

• Body temperature of 103 degrees Fahrenheit or higher
• Confusion
• Rapid heartbeat
• Hot, red skin
• Loss of consciousness

If you suspect someone is experiencing heat stroke, call 911 immediately.

Tips to Stay Safe

• Drink water regularly, even if you do not feel thirsty.
• Wear lightweight, light-colored clothing.
• Limit outdoor activities during the hottest part of the day.
• Take frequent breaks in the shade or air conditioning.
• Never leave children or pets in a parked vehicle.
• Check on older adults and others who may be vulnerable during extreme heat.

"One of the best ways to protect yourself is to plan ahead," said Dr. Soma. "If you're spending time outdoors, bring water and sunscreen with you and pay attention to how your body feels."

Most heat-related illnesses can be prevented with a few simple steps.

"The earlier you recognize symptoms and take action, the better," said Dr. Soma. "A little preparation can help you stay healthy and enjoy everything summer has to offer."
