With several counties across Arizona, including Maricopa, currently under an extreme heat advisory, it’s critical to take precautions to stay safe. Arizona’s summer temperatures can easily rise above 110°F, placing residents — especially older adults — at increased risk of heat-related illness. Whether you're a year-round resident of Sun City West or new to the West Valley, here's what you need to know to stay safe during dangerously high temperatures.
1. Stay Hydrated — Even If You’re Not Thirsty
In extreme heat, your body loses water faster than usual. Dehydration can sneak up quickly, especially for older adults who may not feel thirsty until they’re already low on fluids.
- Drink plenty of water throughout the day — even indoors.
- Avoid sugary, caffeinated, or alcoholic beverages.
- If you’re going outside, bring water with you and sip frequently.
Pro tip: Add a pinch of salt or an electrolyte tablet if you’re sweating a lot or taking diuretics.
2. Know the Symptoms of Heat-Related Illness
Recognizing early signs of heat stress can help prevent a medical emergency. Heat-related illnesses range from mild heat exhaustion to life-threatening heat stroke. Watch for these symptoms:
Heat Exhaustion:
- Heavy sweating
- Weakness or dizziness
- Nausea or vomiting
- Headache
- Cool, clammy skin
Heat Stroke (a medical emergency):
- Confusion or slurred speech
- Fainting or unconsciousness
- Body temperature above 103°F
- Hot, dry skin or rapid pulse
What to do: Move to a cool area immediately, sip water, and call 911 if symptoms are severe.
3. Understand Medication Risks in the Heat
Many common medications can increase your sensitivity to heat or impair your body’s ability to regulate temperature. These include:
- Diuretics (water pills)
- Beta-blockers
- Blood pressure medications
- Antidepressants
- Antihistamines
If you or someone you know takes these medications, extra caution is warranted during heat advisories. Talk to your doctor or pharmacist about side effects related to hot weather.
4. Cool Down Smartly
- Stay indoors between 10 AM and 6 PM if possible.
- Use air conditioning. If your home doesn’t have A/C, visit a local cooling center (check the Maricopa County Public Health website for locations).
- Wear light-colored, breathable clothing.
- Take cool showers or use damp towels to bring down body temperature.
5. Check On Neighbors and Loved Ones
Extreme heat can be especially dangerous for:
- Older adults
- People with chronic illnesses
- Those living alone
- Pets
Make a quick phone call or knock on a neighbor’s door — especially if they don’t have access to A/C or transportation.
Final Thoughts
