Record-breaking heat waves are sweeping across the U.S. this July, with temperatures soaring well past 100°F in many states. For active adults 45 and older, extreme heat poses serious health risks—even if you’re fit and on the go.
Whether you’re hiking, biking, gardening, or traveling this summer, it’s important to understand how heat affects your body, and what you can do to stay safe and cool.
Why Heat Can Be More Dangerous After Age 45
Even before entering your senior years, your body’s ability to regulate temperature begins to change. According to the Centers for Disease Control and Prevention (CDC), adults over 45 may experience:
- Reduced sweating efficiency, making it harder to cool down
- Slower circulation, affecting heat dispersion
- Higher risk of dehydration, especially when combined with medications or health conditions
Warning Signs of Heat-Related Illness
Knowing the symptoms of heat stress can help prevent emergencies. Watch for:
- Excessive sweating or clammy skin
- Headache, dizziness, or fatigue
- Muscle cramps
- Nausea or vomiting
- Confusion or fainting
- Body temperature over 103°F
If someone shows signs of heat stroke, call 911 immediately. Move them to a cool area and apply cold compresses.
9 Expert-Backed Tips to Stay Cool and Hydrated
1. Exercise Early or Late
Avoid peak heat hours—typically between 11 a.m. and 4 p.m. Opt for morning walks, evening bike rides, or shaded routes.
2. Wear Light, Breathable Clothing
Choose moisture-wicking, light-colored clothes that allow sweat to evaporate and body heat to escape.
3. Hydrate Regularly
Drink water consistently throughout the day—don’t wait until you’re thirsty.
4. Replenish Electrolytes
Use low-sugar electrolyte drinks or tablets when sweating heavily or exercising over an hour.
5. Use Cooling Tools
Carry a cooling towel or mist spray. Take a cool shower post-activity and rest in shaded or air-conditioned spaces.
6. Limit Alcohol and Caffeine
Both contribute to dehydration. Stick to water or electrolyte-rich beverages.
7. Check the Heat Index
Use local weather apps or visit ready.gov/heat to track the day’s heat index.
8. Know Your Medications
Some medications can affect hydration or heat tolerance. Ask your doctor about risks.
9. Take Breaks and Buddy Up
Exercise with a friend or notify someone of your plans in extreme heat.
Build Your Personal Hot Weather Plan
- Identify local cooling centers or public air-conditioned spaces
- Keep water, hats, and electrolyte packs on hand
- Set smartphone reminders to hydrate
- Monitor weather alerts and advisories
