A heatwave is “a prolonged period of abnormally hot weather,” and these periods can be brutal, making even the simplest daily tasks uncomfortable and more difficult. Staying cool and hydrated is crucial, yet certain activities and habits can make life in a heatwave even worse—here are 17 things to avoid when temperatures are unusually high.
Strenuous Activity
We all know exercise is good for us, but don’t assume you can stick to your usual exercise schedule during a heatwave. Avoid outdoor activities like running, hiking, or biking, or change the time of day you engage in them—early morning or late at night is best. If you must exercise outdoors during the heat of the day, choose activities like swimming or walking in the woods.
Leaving Children or Pets in Parked Cars
Consumer Reports writes, “About 37 children die each year from vehicular heatstroke,” and this is especially likely during heatwaves when the ambient temperature and amount of solar radiation are above normal levels. Even with windows cracked, the temperature in a car can rise quickly and cause heat stroke or death for anyone unable to escape, including infants and pets.
Forgetting Hydration
Even mild dehydration can lead to headaches, fatigue, and dizziness, and many people fail to adjust the amount of fluids they drink during especially hot spells. Remember that your body will need more water to keep you cool and that more is lost during sweating. Avoid salty or dry foods and ensure you constantly sip water, even when you don’t feel thirsty.
Skipping Sunscreen
Sunburn is not only uncomfortable and unsightly, but it can worsen heat stroke symptoms and have long-term health effects like skin cancer. Always use sunscreen with SPF 30 or higher and apply it liberally and regularly, especially when sweating or swimming. Pay attention to easy-to-miss spots like your ears, hair parting, and ears, and avoid the midday sun entirely.
Drinking Too Many Sugary Drinks
Sugary drinks may seem like an ideal way to quench your thirst but watch out for excessive sugar content or sports drinks that contain a lot of electrolytes. These added molecules can be challenging for your body to absorb effectively in hot weather, so you should only drink them in moderation. Drink as much cold water as you can, or opt for unsweetened iced tea or coconut water.
Cooking Hot Food
Salads, smoothies, fresh fruit, yogurt, and sandwiches are your friends during hot weather! They don’t introduce extra heat to your body and are also more comfortable to cook because they don’t require the use of heat-generating appliances like ovens and stoves. If you must cook, use microwaves, barbecues, or toaster ovens and wait until the evening when it’s cooler.
Wearing Inappropriate Clothing
Avoid thick or tight-fitting clothing (like elasticated nylon or spandex) that traps heat close to your body and opt for light-colored garments that reflect sunlight instead of absorbing it. CNN recommends wearing loose-fitting, breathable clothing during a heatwave and states that natural fibers like cotton or linen allow for maximum air circulation, thus keeping you cooler.
Hot Showers or Baths
This might seem like a no-brainer, but avoid washing yourself with hot or even warm water. Although cool water may feel exceptionally cold on hot skin, it will help cool your blood and lower your body temperature rather than raising it even more. If you feel like cool water doesn’t get you as ‘clean,’ use plenty of soap to cleanse your body and remove sweat and dirt.
Leaving Curtains and Blinds Open
Sunlight streaming through windows significantly increases the temperature inside your home, much like in a greenhouse. To avoid making your interior environment hotter than it needs to be, close curtains and blinds on windows facing the sun, particularly during the hottest part of the day. If your area is prone to heatwaves, consider blackout blinds specifically designed to block heat.
Walking Your Dog
Remember that your pooch doesn’t have shoes as a barrier between them and the ground, so their paws are vulnerable to being burnt on pavements and other hot surfaces. Never walk your dog between 11am and 3pm during a heatwave, and try to limit exercise to early morning or evening. If your dog enjoys water, you could consider taking them to the beach or lake for a dip.
Leaving Electronics on Standby
All electronics generate some heat, even when in standby mode, so it’s a good idea to unplug chargers and switch off televisions and speakers when not in use. This not only avoids unnecessary heat generation but will also help reduce your electricity bill at a time when you may be suffering from extra charges due to air conditioning units needing to be left on.
Arguing or Getting Stressed
We know, we know—it’s easier said than done! But bear in mind that anger and stress have physical consequences, including an increased body temperature. Better Health warns that getting angry causes the release of the hormones cortisol and adrenaline, which raise your blood pressure and increase perspiration and heart rate. Try to stay calm and cool instead.
Neglecting Pets
Furry pets like cats, dogs, and rodents can’t take their coats off in hot weather, so they may struggle to stay cool. Just like humans, they can suffer from heat stroke and sunburn, so always ensure that outdoor pets have sufficient shade and all pets have plenty of cold water. You could even consider extra measures like ice baths, cooling pads, or hydrating treats, e.g., cucumber.
Consuming Excessive Alcohol
A cold beer or a chilled glass of white wine might be tempting on a hot day, but you should be aware that even small amounts of alcohol worsen heat stroke symptoms and cause dehydration. Wait until the late evening before indulging (in moderation), or switch to hydrating, non-alcoholic alternatives like diluted fruit juice, low-sugar sodas, and coconut water.
Skipping Air Conditioning Maintenance
As soon as a heatwave is predicted, ensure your air conditioning units are up-to-date with their maintenance and servicing requirements. You will need reliable cooling throughout the hottest times of the year, and you don’t want to be left scrambling for repair services should your units stop working. Regular servicing will also ensure the cool air they produce is safe and clean.
Diuretics
Certain medications, like diuretics used for blood pressure control, can increase urination and contribute to dehydration. If your area is due to suffer from unusually high temperatures, consult your doctor about taking any diuretic medication during the heatwave. They might recommend adjustments to your dosage or suggest alternative medications during very hot weather.
Ignoring Hosepipe Bans
Local authorities sometimes ban non-essential water usage whenever they predict that drought may result in insufficient water for all residents in an area. Don’t wash your car or patio, or use a hose to water your garden, if these activities have been banned during a heatwave. It’s not only selfish but could result in a fine should you get discovered.
