Extreme Heat Safety When Living Alone

Heat waves kill more people than any other weather event. When you live alone, heat exhaustion can progress to heat stroke with no one to notice the warning signs.

Extreme heat causes more deaths annually than hurricanes, tornadoes, and floods combined. People living alone -- especially older adults -- are at the highest risk because no one is there to notice symptoms.

The Challenge

Heat exhaustion causes confusion and fatigue, making it hard to recognize you are in danger when alone

No one to bring you water, cool you down, or call 911 if heat stroke sets in

AC failures during heat waves can turn your home into a dangerous oven with no one to check on you

How I'm Alive Helps

Stay hydrated, close blinds during peak sun, and know the location of your nearest cooling center

Set multiple I'm Alive check-ins during heat waves so contacts are alerted quickly if you become incapacitated

Check that your AC is working before heat season and have a backup plan if it fails

Preparing for Extreme Heat When You Live Alone

Before heat season, service your air conditioning and have a backup plan if it fails -- identify cooling centers, libraries, malls, or friends with AC you can visit. Buy a battery-powered fan and keep frozen water bottles on hand. Install blackout curtains or reflective window film on sun-facing windows. Stock up on water and electrolyte drinks. Know the signs of heat exhaustion: heavy sweating, weakness, cold and clammy skin, nausea, and dizziness. Heat stroke is a medical emergency marked by high body temperature, hot and dry skin, rapid pulse, and confusion. When you live alone, the progression from exhaustion to stroke can happen without anyone noticing.

Staying Safe During a Heat Wave

Stay indoors during peak heat hours, typically 10 a.m. to 4 p.m. Drink water regularly even if you do not feel thirsty -- thirst is a late indicator of dehydration. Take cool showers, apply wet towels to your neck and wrists, and eat light meals. Avoid alcohol and caffeine, which accelerate dehydration. If your AC fails, go to a cooling center immediately. Do not try to tough it out. Check in with your emergency contacts more frequently during heat waves. Increase your I'm Alive check-in frequency so that if heat incapacitates you, the gap before someone is alerted is as short as possible. Even a few hours of delay in heat stroke treatment can be fatal.

Frequently Asked Questions

What is the difference between heat exhaustion and heat stroke?

Heat exhaustion causes heavy sweating, weakness, nausea, dizziness, and cool clammy skin. It is serious but treatable by cooling down and hydrating. Heat stroke is a life-threatening emergency where body temperature exceeds 103 degrees, skin becomes hot and dry, and confusion sets in. Call 911 immediately for heat stroke.

How do I stay cool without air conditioning?

Close blinds and curtains on sun-facing windows, use fans with a bowl of ice in front, take cool showers, apply wet towels to pulse points, drink cold water constantly, and go to a cooling center or air-conditioned public building during peak hours. Do not rely solely on fans when temperatures exceed 95 degrees.

How much water should I drink during a heat wave?

Drink at least eight to twelve cups of water per day during extreme heat, more if you are sweating heavily. Do not wait until you feel thirsty. Include electrolyte drinks if sweating heavily. Avoid alcohol and excessive caffeine as they increase dehydration.

How does I'm Alive help during heat waves?

Heat stroke causes confusion and loss of consciousness rapidly. If extreme heat incapacitates you, your I'm Alive check-in ensures your emergency contacts are alerted automatically. During heat waves, consider increasing your check-in frequency so the alert window is shorter and help arrives faster.
