There is a lot of buzz about the start of football season on all levels, whether pro, college, high school or other. But the excitement over a new football season — or even the start of a new outdoor workout routine — shouldn’t overshadow the fact that it’s hot outside. Be careful.

Anyone exercising outside, whether at football practice or out jogging or hiking, should take extra precaution when exerting themselves in the heat.

The Centers for Disease Control and Prevention cautions those exercising or practicing while it’s hot outside to take the following precautions:

• Limit outdoor activity, especially during the middle of the day when the sun is hottest.
• Wear and reapply sunscreen as indicated on the package.
• Schedule workouts and practices earlier or later in the day when the temperature is cooler.
• Pace activity. Start activities slow and pick up the pace gradually.
• Drink more water than usual, and don’t wait until you’re thirsty to drink more. Muscle cramping may be an early sign of heat-related illness.
• Monitor a teammate’s condition, and have someone do the same for you.
• Wear loose, lightweight, light-colored clothing.

People who exercise in extreme heat are more likely to become dehydrated and get heat-related illness. Seek medical care immediately if you or a teammate has symptoms of heat-related illness.
