Tips to stay cool in the heat of the summer:
1. Wear loose-fitting clothing, preferably of a light color.
2. Cotton clothing will keep you cooler than many synthetics.
3. Keep plastic bottles of water in the freezer, grab one when you're ready to go outside. As the ice melts, you'll have a supply of cold water with you.
4. Drink sports drinks as well as water for other sources of electrolytes.
5. Avoid caffeine as it promotes dehydration.
