Summer Heat Safety for Seniors in Arizona’s East Valley

As the East Valley sun climbs higher and temperatures in Gilbert, Chandler, Mesa, Tempe, and Queen Creek push well past 100°F, summer in Arizona is more than just a season—it’s a serious health consideration for older adults and their families. With the right knowledge, local resources, and a trusted support system, seniors can stay safe, comfortable, and connected all season long.

Why Arizona Summers Are Especially Risky for Seniors

Arizona is one of the hottest places in the country from May through September, and the numbers tell a sobering story. According to the Arizona Department of Health Services, more than 4,320 people died from exposure to excessive heat in Arizona between 2013 and 2024, with approximately 4,298 people visiting Arizona emergency rooms every year due to heat-related illnesses [1]. In Maricopa County alone—which includes the entire East Valley—608 confirmed heat-related deaths were recorded in 2024, marking the first year-over-year decrease since 2014, despite 2024 being the hottest summer on record [2]. Notably, nearly 60% of those who died were individuals aged 50 or older [3].

These statistics are not meant to alarm, but to inform. Understanding the risk is the first step toward preventing it.

Why Older Adults Are More Vulnerable

Aging changes the way the body responds to heat in fundamental ways. Research published in peer-reviewed medical literature shows that older adults exhibit reduced sweating and impaired cardiovascular responses to heat, resulting in greater heat storage, faster increases in core body temperature, and a higher risk of dehydration and fatigue compared to younger adults [4]. In plain terms: the body’s natural cooling system becomes less efficient with age.

The National Institute on Aging notes that older adults are at higher risk for heat-related illnesses due to factors including cardiovascular, lung, or kidney disease, as well as taking medications such as diuretics, sedatives, and blood pressure medicines that can make it harder for the body to cool itself [5]. Studies also show that it can be hard for even healthy older adults to tell when it’s too hot or if they’re dehydrated—and cognitive decline can make this even more challenging [6].

Social isolation adds another layer of risk. Research has found that social isolation is a major risk factor for heat-related death: when people are alone and others are not regularly checking on them, there is often nobody to help them as they suffer from the heat [7].

Practical Heat Safety Tips for East Valley Seniors

The good news: heat-related illness is largely preventable. Here are evidence-based steps seniors and their families can take right now:

1. Stay Hydrated—Even When You’re Not Thirsty

Drink water regularly, even if you don’t feel thirsty. Dehydration is a leading factor influencing hospitalization for older adults, who commonly don’t hydrate enough—and the Arizona summer months put people at an increased risk [8]. Avoid alcohol and caffeine, which can dehydrate you [9]. Incorporating hydrating foods like watermelon, cucumbers, and oranges can also help sustain hydration levels during intense summer heat [5].

2. Keep Cool Indoors During Peak Hours

Avoid strenuous activity during peak heat hours, usually midday to late afternoon [9]. If you need fresh air, choose shaded outdoor spots or rest indoors where it’s coolest. Keep blinds, curtains, or blackout shades closed during midday to block heat from entering the home [10]. Air conditioning is vital—the CDC advises seniors to stay in air-conditioned buildings as much as possible and not to rely on a fan as a main cooling source when it’s really hot outside [11].

Importantly, Maricopa County data found that among indoor heat-related deaths in 2024, 88% had an air conditioning unit present, but 70% of those units were non-functional [2]. Make sure your AC is serviced before summer arrives.

3. Dress for the Heat

Choose light-colored, loose-fitting clothing made of breathable fabrics—it helps your body regulate temperature and avoid overheating [9]. Wear a wide-brimmed hat and use SPF 30+ sunscreen when going outdoors [11].

4. Plan Outdoor Activities Wisely

If you want to take a walk or run errands, aim for early morning hours—before 9 a.m. if possible. Temperatures are cooler, and air quality tends to be better in the morning [10]. Bring a water bottle, wear light-colored clothing, and consider walking with a friend for both safety and socializing [8].

5. Know the Warning Signs

Seek medical care immediately if you or someone you know has symptoms of heat-related illness, including muscle cramps, headaches, vomiting, confusion, no longer sweating, and rapid heart rate [11]. Without prompt intervention, heat exhaustion can progress to heatstroke, which can cause permanent organ damage or death [12].

Local Safety Resources for East Valley Seniors

You don’t have to navigate summer safety alone. The East Valley has a number of local resources designed to help seniors stay safe:

• Maricopa County Heat Relief Network: Runs from May 1 through September 30 and provides life-saving resources through a variety of community partners [13]. To find nearby cooling and respite centers, visit azmag.gov/heatrelief or call 2-1-1. Live operators are available in English and Spanish from 9 a.m. to 7 p.m. daily to help residents find cooling centers, transportation help, utility support, or emergency A/C repair [14].
• Chandler Heat Relief Resources: The City of Chandler provides emergency preparedness information and heat relief resources to help residents stay safe during heat waves, power outages, and other hazards [15]. Visit chandleraz.gov/residents/neighborhood-resources/heat-relief for local heat relief locations.
• Salvation Army Heat Respite Centers: The Chandler Corps (85 E. Saragosa St.) operates as a heat respite center, open Monday-Saturday, 9 a.m.-7 p.m., with extended Sunday hours during Excessive Heat Warnings [16].

• Maricopa County Heat Surveillance Dashboard: Track real-time heat-related illness and death data throughout the season at maricopa.gov/heat [12].

The Role of Companionship in Summer Safety

Beyond the practical tips, one of the most powerful protections against heat-related harm is human connection. Research has confirmed that social isolation is a major factor in heat-related deaths, and that more social contact is strongly associated with lower heat-related death rates [7]. For seniors living alone, having someone check in regularly—whether a neighbor, family member, or caregiver—can be life-saving.

Maricopa County’s own public health guidance echoes this: “Check on older adults and people living alone often” [12]. It’s a simple act that can make an enormous difference.
