Staying Safe During the Heat
Extreme heat poses significant health risks, especially for older adults, young children, and individuals with underlying health conditions. To combat dehydration, it’s important to drink water regularly, even before you feel thirsty. Remember that parked vehicles can quickly become dangerously hot, so never leave children or pets inside.
Remember, your pets deserve special attention during the heat. Lots of water, providing shade, trimming back their walks during the hottest parts of the day is a good idea too. Also remember to check the heat of the pavement, before letting your dog walk on it. It might feel fine through your shoes, but to the pads on your dog’s feet it might be way too hot.
Wardrobe Suggestions
With the heat in full force, dressing in lightweight, breathable fabrics is key. Light-colored clothing will help reflect the sun’s rays, and don’t forget a hat and sunglasses for added protection. Given the high UV index, applying sunscreen is essential for skin protection.
