This month’s topic for Gym Talk is "Heat Safety Awareness".
Hot weather can be dangerous, and seniors over the age of 65 are among those most at risk for heat exhaustion. Now that the hot weather has arrived it's important to know the signs of heat exhaustion and how to stay cool.
The human body regulates temperature through sweating, until exposed to more heat than the body can handle. As you become older the ability to notice changes in your own body’s temperature decreases. Others at risk for heat illness include infants and young children, people who are ill, those with chronic health conditions or on certain medications, and people who are overweight. Health conditions can make the body less able to adapt to the heat. Also, some medicines can contribute to dehydration.
A few simple precautions are all that’s needed to help keep you safe. Drink plenty of water even if you’re not thirsty. Avoid alcoholic or caffeinated drinks as they contribute to dehydration. Wear appropriate clothing, such as light-colored, lightweight, loose fitting, a hat and sunscreen. Stay indoors during mid-day hours. The best time to be outside is before 10am or after 6pm when the temperature is usually cooler. Take it easy, avoid strenuous activities especially outside when it is very hot. Pace yourself when you exert your body. Watch the heat index. When the humidity is high the body’s ability to cool itself through sweating is impaired. Seek air-conditioned environments or try a cool bath or shower. And lastly, know the warning signs of heat-related illnesses.
