When does hot weather become a real risk? Once high temperatures stretch into days and nights, your body starts working overtime just to stay cool. That strain can lead to heat exhaustion, dehydration, or worse. This post covers heatwave safety tips that’ll keep you and your family refreshed and protected on the hottest days.
What is a Heatwave?
The National Weather Service defines a heatwave as two or more consecutive days of abnormally and uncomfortably hot and unusually humid weather. In recent decades, American cities have experienced a rise in prolonged heat events from an average of two per summer in the 1960s to about six today. On average, heatwaves in major U.S. cities stick around for about four days at a time. That stretch is long enough to raise health risks if you’re not prepared.
5 Helpful Tips to Beat the Heat
Heat can sneak up on your body and sap your energy. Here’s how to stay cool when the mercury climbs:
- Drink water consistently throughout the day to replace minerals you lose when sweating. During extreme heat, the body can perspire up to 2.5 liters per hour, so sipping water frequently helps prevent dehydration. Carry a reusable bottle and set achievable goals. For example, finish the whole flask by mid‑morning and complete another by lunchtime. Consistent intake helps your body regulate its temperature and prevents headaches or cramps.
- Save outdoor tasks for cooler hours to avoid heat exhaustion. Early mornings or evenings are often 15°F cooler than midday highs according to diurnal temperature studies. Plan lawn work, dog walks, or other errands around those times to reduce heat exposure.
- Wear loose and light-colored clothing and Ultraviolet Protection Factor (UPF)-rated materials to avoid sun damage. Wearing a light shirt can protect you better than you might think as fabrics with a UPF 50 rating stop about 98 percent of UV rays. Putting on loose cut pieces also let air flow close to your skin and help cool you down. Add a wide‑brimmed hat to shield your face and neck.
- Set up cooling stations. Using an electric fan can lower your core temperature by 0.3 °C, especially when you place a damp towel in front. Don’t forget to mist the towel every now and then.
- Snack on water-rich foods to replenish fluids and nutrients. Watermelon contains 92 percent water which is why it’s one of the top hydrating foods this season. Meanwhile, cucumbers and berries hold nearly as much water as well as electrolytes and vitamins. Keep a bowl of cut fruit in the fridge for quick access.
Heatwave Safety Tips: Advice for All Ages During Hot Weather
Heatwaves can put extra strain on pregnant women, young children, and older adults. Let’s examine tailored advice to help each group stay comfortable and healthy during extreme temperatures.
Advice for Parents with Babies and Young Children
Babies and young children struggle to regulate body temperature so even short heat spells can overwhelm them. Dress little ones in light cotton clothes and keep them in shaded or air-conditioned areas whenever possible. Additionally, hydrate infants every 15–20 minutes especially when temperatures soar.
Advice for Pregnant Women
During pregnancy, the body works harder to stay cool which can stress both the mother and the baby. In fact, research links each 1 °C rise in maternal temperature to a higher risk of dehydration-related issues during pregnancy. Stay indoors during peak heat hours and rest often in a cool room or use a fan directed at your skin. Also, drink at least 10 cups of water daily and consume an electrolyte-rich beverage.
Advice for Seniors
Adults aged 65 and up often lose the ability to sweat efficiently and regulate body temperature. Following the 1995 Chicago heat wave, hospital admissions for people aged 65 and older increased by 35 percent which highlights the importance of monitoring heat exposure in seniors. Check in on older relatives at least twice a day and encourage them to sip water regularly even if they don’t feel thirsty. Keep indoor temperatures between 68 °F and 74 °F. To help lower body heat, apply cool and damp cloths to their forehead or back of the neck.
Heatwave Safety Tips: A Quick Reminder for the Hottest Days
If the temperature spikes, hydrate frequently and move yard work and daily walks to early mornings or evenings. Most importantly, check on family members who need extra care.

FAQ: Heatwave Safety Tips
- What temperature counts as a heatwave?
A heatwave typically means three or more days of unusually high temperatures for your area—often above 90°F in many U.S. cities. - How much water should I drink during a heatwave?
Aim for at least 8–10 cups a day, more if you’re sweating or active. Sip steadily instead of waiting until you feel thirsty. - Is it safe to exercise during extreme heat?
Limit workouts to early morning or evening hours. Take frequent breaks, drink water often, and avoid outdoor exercise during peak heat. - Can fans help cool me down during a heatwave?
Yes, especially when paired with a damp cloth or spray mist. However, fans alone may not prevent heat-related illness in very high temps. - What should babies wear during a heatwave?
Dress them in light, breathable cotton. Keep them in shaded or air-conditioned areas and offer small sips of water if they’re over 6 months. - How can I tell if my child is overheating?
Watch for red skin, fussiness, rapid breathing, or lack of sweat. Move them to a cooler spot and offer fluids right away. - What’s the best way to cool down indoors without AC?
Use fans with wet towels, keep curtains closed during the day, and avoid using the oven or stove. - What foods help with hydration?
Snack on water-rich foods like watermelon, cucumbers, strawberries, and oranges to support hydration. - How often should I check on elderly relatives in the heat?
Check in at least twice a day. Make sure they’re drinking fluids, staying cool, and not showing signs of fatigue or confusion. - How do I know if I’m experiencing heat exhaustion?
Look for heavy sweating, dizziness, headache, or nausea. Move to a cool area, sip water, and rest—if symptoms continue, seek medical help.
