As summer arrives, many people embrace outdoor activities—hiking, swimming, gardening, or relaxing at the beach. These warm months bring plenty of enjoyment, but it’s important to take precautions to stay safe in the heat.
Older adults are especially vulnerable to high temperatures. In many parts of the country—particularly retirement-popular regions such as Florida and Arizona—daytime highs can exceed 100°F. When temperatures climb that high, heat-related illnesses become a serious risk. Two of the most dangerous conditions are heat exhaustion and heat stroke; both require prompt recognition and action.
Heat exhaustion symptoms:
- Muscle cramps
- Heavy sweating
- Nausea
- Pale, cool skin
- Weakness or fatigue
Heat stroke symptoms:
- Hot, dry, and flushed skin
- Vomiting
- Confusion or disorientation
- Severe, throbbing headache
- Body temperature of 103°F (39.4°C) or higher
- Rapid breathing and fast heart rate
If you or someone nearby shows these signs, call 911 immediately. While waiting for emergency responders, move the person to a cooler environment—shade or an air-conditioned space—remove excess clothing, and use cool water, ice packs, or misting and fans to lower body temperature. Do not give fluids if the person is unconscious or vomiting.
Beyond heat exhaustion and heat stroke, high summer temperatures can worsen chronic conditions common in older adults, such as heart disease and chronic obstructive pulmonary disease (COPD). For all seniors—especially those with existing health issues—staying well hydrated is essential. Encourage regular intake of water or other non-caffeinated, non-alcoholic beverages, and take frequent breaks from the sun. Seek shade or move indoors to air-conditioned spaces when temperatures rise, and apply broad-spectrum sunscreen of SPF 30 or higher when spending time outdoors.
Caregivers and neighbors should also watch out for homebound older adults. Make sure they have functioning cooling systems, access to fluids, and a way to call for help if needed. Regular check-ins during heat waves can prevent dangerous situations and provide peace of mind.
