Heat isn’t just uncomfortable – excess heat is dangerous, especially for seniors and people with health concerns. Hot temperatures can bring on heat exhaustion and heat stroke, both of which can be severe and life threatening. Summers are getting hotter and longer, but planning ahead can help you weather the summer heat.
Stifling temperatures have become more common because of climate change. This is true even in places known for moderate weather, which can be doubly dangerous since fewer homes have air conditioning.
Be prepared and be safe!
Risk factors for summer heat harms
Risk factors for heat-related illness include age, medical history, and medications.
- Adults over age 65 are at a higher risk, as their bodies adjust to heat more slowly.
- People with heart, lung, or kidney disease, alcoholism, diabetes, and other chronic diseases may be at a higher risk due to impaired temperature regulation. Those with Alzheimer’s and other dementias may be unaware of extreme temperatures and of how to protect themselves.
- Certain medications, such as fluid pills and blood pressure medications, may lead to dehydration.
- In addition, some older adults on fixed incomes might have limited resources for upgrading or replacing HVAC equipment, and energy costs can exacerbate affordability concerns.
Tips for staying safe during the summer heat
At home
- Have an HVAC professional check the health of your cooling system.
- Avoid using the oven or stove on hot days.
- Cool down with wet rags, a shower, or a bath.
- Keep blinds or curtains closed to keep out the hot sun.
- Don’t rely on a fan as your primary cooling source during a heat wave.
- Have a contingency plan in case you are without power or air conditioning – a relative, friend, libraries, shopping malls, or local social services or senior services organizations. Your health department may be able to help you locate an air-conditioned cooling center, too.
- Stay hydrated, even inside. Your body relies on sweat to cool you, so be sure to replenish your fluids.
Out and about
- Plan walks and other outings first thing in the morning or later in the evening.
- Find shady areas for resting and exercising, especially natural areas away from the city and asphalt roads.
- Wear loose, light-colored, breathable clothing. Cotton or linen fabrics or moisture-wicking materials work best.
- A wet towel or ice pack can cool you down. Cooling towels are often marketed for people during exercise, but they can help regardless.
- Carry hydration at all times, either water or an electrolyte hydration beverage.
- Don’t wait until you’re thirsty to drink.
- Wear a wide-brimmed hat.
- Beware of alcohol – as a diuretic, it can dehydrate you.

Engage with others
Caregivers and friends can be your first line of defense against heat-related illness. They can help monitor your symptoms and make sure you’re sufficiently hydrated – especially during heat events in your area. They could also call your doctor or 911, if necessary.
However, if you are alone, don’t hesitate to reach for the phone if you suddenly feel unwell. Call 911 first, and then call a friend or neighbor.
In fact, checking on friends and neighbors periodically will make them less hesitant to do the same for you in the future.
After all, we’re all in this increasingly hot world together.
