Keeping an aging parent safe in summer heat

Older bodies handle heat poorly. They sweat less, feel thirst less, and often take medications that make it worse. A hot week is a real risk for a parent living alone. Here's how to stay ahead of it.

Why older adults are more at risk

With age, the body's ability to regulate temperature declines, the sense of thirst fades, and chronic conditions plus common medications (some blood-pressure and heart drugs, diuretics, certain antidepressants) can impair cooling. Someone who feels “fine” can be dehydrated or overheating without realizing it.

During a heat wave, check that they're:

• In air conditioning, or somewhere cool. A fan alone isn't enough in high heat.
• Drinking water regularly, even without feeling thirsty.
• Wearing light clothing and staying out of midday sun.
• Not pushing through yard work or errands in the heat of the day.

Warning signs of heat illness: act fast

Heavy sweating then suddenly no sweating; dizziness, confusion, or a headache; nausea; a body temperature that's rising; hot, dry, red skin. Confusion and hot dry skin can signal heat stroke, which is an emergency: call 911. When in doubt in a heat wave, check in more, not less.

Build in a daily check

A hot stretch is exactly when a daily call or a medical alert device earns its keep. If your parent lives alone, set a standing check-in for the duration of the heat wave.
