With a heat advisory in place for this weekend in the San Francisco Bay Area, it's important to remember hot weather can cause hyperthermiaโa collective term for illnesses including heat stroke, as well as swelling, dizziness, cramps, or exhaustion caused by high temperatures. Older adults are especially susceptible to these conditions.
Here are seven ways to keep yourself and your loved ones safe from the heat:
1. Seek out air-conditioning. If your loved one doesn't have AC at home, contact your local health department or senior center to find air-conditioned spaces that are open to the public.
2. Avoid using the stove or oven. These appliances heat up indoor spaces fast. It's a great time for salads or sandwiches!
3. Dress for the heat. Loose, lightweight clothing breathes best. Outdoors, add a hat, sunglasses, and other sun protection.
4. Stay hydrated. Remind them to drink more water than usual, and not to wait until they feel thirsty. When in doubt, they can ask their doctor how much water is right for them.
5. Reduce activity levels. Save strenuous walks for cooler days, and make sure they're getting enough rest.
6. Stay in touch. Heat-induced illness can cause confusion or even loss of consciousness. Check on your older loved one twice a day during extremely hot weather.
7. Stay informed. Watch the local news for extreme heat alerts so you can plan ahead together.
