It’s Hot! How Caregivers Can Protect Senior Loved Ones From Heat Related Illness

By Sue Donahue

This summer, heatwaves are smashing records all over the country. We are all feeling it, but extreme temperatures have the greatest effect on the very young and the oldest among us. The CDC estimates that heat deaths jumped 56% between 2018 and 2021 with people aged 65 years or older being more prone to suffering from heat-related health problems.

There are physical reasons older adults are more sensitive to varying temperatures. Although vital signs such as body temperature, pulse and heart rate don’t change significantly as we age, the body’s ability to manage how it deals with the effects of extreme temperatures do.

It’s especially important for those caring for a parent or older adult to understand and recognize the sign of a potential temperature related health issue before it becomes a big problem.

From the experts: What to know about the how our aging body changes how it manages extreme temperatures:

  • It takes longer for the heart rate to increase at the start and slow down afterwards. for older adults. The highest heart rate with exercise is also lower.
  • Breathing Rate. Lung function decreases as we age. Every year.
  • There is less fat under the skin as we age, making it harder for older adults to get and stay warm. It may also be why your Mom likes to keep her home a toasty 78 degrees.
  • The body’s natural cooling system is less efficient, and an older adult may not be able to tell when they are overheated, increasing their risk of heat related illnesses. Heat stress presents the first signs that someone may be having issues with their body temperature. Without attention, exposure to extreme heat can result in heat rash, cramps, heat exhaustion or heat stroke
  • A fever is a sign of infection. It’s important to connect with a loved one’s doctor to check out this and any other additional symptoms, if any.
  • Some commonly used/prescribed medications used to treat health issues in older adults can also affect the ability to regulate temperature. These include:
    • Diuretics (can raise body temperature)
    • Antihistamines, decongestants (can raise body temperature)
    • Blood pressure medication/Beta blockers (can raise body temperature)
    • Psychiatric medications (can raise body temperature)
    • NSAID pain relievers (can lower body temperature)

Keeping Older Adults Safe Inside Their Home 

My mother-in-law likes her home warm and adamantly objects to the idea of air conditioning. We knew how bad the heatwave was when, after a few days of 90+ degree temperatures, even she succumbed and put on the central air in her condo. When it suddenly stopped working, she called on us to come help her fix it. We put in a window unit because no one was available to come out to fix it. Not all older adults have access to help that quickly, and not all caregivers live close enough to be able to help. If you are caring for someone, make sure their home or apartment is at a temperature that is comfortable and safe. In general, temperatures are around 78 degrees.

Caregiver Tip: Make sure your loved one’s home is safe and cool. If you’re not nearby, arrange for a neighbor, friend, or volunteer program (like Meals on Wheels) to perform occasional check-ins during heatwaves.

How Technology Like Livindi Helps  

Smart caregiving technology, like Livindi, offers tools that make heat safety easier:

  • In-home temperature sensors notify caregivers when it’s too hot or cold

  • Live video check-ins allow family members to assess appearance, comfort, and well-being

  • Wearable alerts and safety buttons enable seniors to call for help if they’re feeling unwell

This kind of remote monitoring provides peace of mind when you can’t be there in person.

Heat Safety Tips for Inside and Outside the Home

✅ Stay Hydrated: Encourage frequent sips of water throughout the day
✅ Avoid Stove/Oven Use: Prepare no-cook or microwave meals to reduce indoor heat
✅ Use Fans or AC: If no AC is available, visit malls, libraries, or community centers
✅ Dress Lightly: Wear light-colored, breathable fabrics and wide-brimmed hats
✅ Protect Skin: Use sunscreen to prevent burns that reduce the body’s ability to cool
✅ Take Cool Breaks: Use damp washcloths, cold showers, or foot baths
✅ Snack Smart: Eat hydrating fruits (like grapes or watermelon) and lightly salted foods
✅ Avoid Overexertion: Move slowly and rest often when it’s hot
✅ Caution with Sports Drinks: These can help with electrolytes, but not all are safe for diabetics or those watching sugar levels
