Here in North Carolina, we’ve had an incredibly hot summer already, and heat-related incidents are a leading environmental threat to older adults. It is estimated that seniors experience nearly 235,000 heat-related illnesses and exacerbations each summer, ranging from dehydration and heat exhaustion to life-threatening heat stroke. In fact, people over age 60 account for more than 80% of all annual heat-related fatalities in the United States.
Recently, the National Institute on Aging (NIA) renewed its warning to seniors about hot-weather risks. Many older adults don’t realize their bodies respond differently to heat than they did decades earlier. Here’s what you need to know about this warning, plus what you can do to prevent heat-related illnesses.
Aging Changes How the Body Regulates Temperature
One reason heat poses a greater threat to older adults is that the body’s ability to regulate temperature naturally changes with age. As people get older, they may sweat less efficiently and experience reduced circulation, making it harder to cool down when temperatures rise. The NIA points out that these changes can make seniors more vulnerable to overheating even when they don’t feel particularly hot. This can be especially dangerous because heat-related illnesses may develop before warning signs become obvious.
On top of that, other factors that commonly affect seniors can play a role too. Certain medications can increase heat sensitivity. Diuretics, blood pressure medications, antihistamines, and some antidepressants may influence hydration levels, sweating, or temperature regulation. It’s always advised that you talk about medication-related heat risks with your healthcare provider (preferably before summer). A medication that works well during cooler months may require additional monitoring during periods of extreme heat.
Additionally, certain chronic conditions can increase your risk of heat-related illnesses, too. Heart disease, diabetes, kidney disease, respiratory disorders, and other common conditions among older adults can reduce the body’s ability to cope with extreme temperatures. Some health issues also make it harder to recognize dehydration or respond appropriately to heat stress. For example, a person with cardiovascular disease may experience greater strain on the heart during periods of high heat.
Seniors managing chronic conditions and/or medications should be particularly cautious during heat waves and follow medical advice closely.
Dehydration, Heat Exhaustion, and Heat Stroke
One of the most overlooked dangers of hot weather is dehydration. As people age, their sense of thirst often becomes less reliable, meaning they may not feel thirsty even when their bodies need fluids. The NIA recommends drinking water regularly throughout the day rather than waiting until thirst develops. Signs of dehydration can include:
- Dizziness
- Fatigue,
- Headache
- Confusion
- Dry mouth
- Dark-colored urine
Additionally, recognizing the warning signs of heat-related illnesses can save lives. Heat exhaustion may cause heavy sweating, weakness, nausea, dizziness, headaches, and cool or clammy skin.
If not addressed, it can progress to heat stroke, a medical emergency that may involve confusion, loss of consciousness, high body temperature, and hot, dry skin. The CDC advises calling 911 immediately if heat stroke is suspected. Quick action can dramatically improve outcomes when serious heat-related illnesses occur.
A Cool Plan Today Can Prevent a Crisis Tomorrow
Fortunately, many heat-related illnesses can be prevented through simple precautions. It is recommended that you stay in air-conditioned environments whenever possible during extreme heat events. Wearing lightweight clothing, avoiding strenuous outdoor activities during peak afternoon temperatures, and taking cool showers can also help reduce risk.
Also, take the time to check the local weather forecast and pay attention to heat advisories. This can allow you to plan your activities safely. Checking local weather forecasts and heat advisories allows seniors to plan activities safely. And don’t forget to drink enough fluids! As temperatures continue to rise during summer months, a proactive approach to heat safety can help older adults remain healthy, independent, and active.
