But remember that exercising in the heat has its own hazards. Here are some reminders when working out in the sun:

• Don't until you're thirsty before getting a drink. By then you're already dehydrated. Drink lots of fluids-especially water, juice, and decaffeinated drinks-15 minutes before you workout and every quarter of an hour throughout the exercise.

• Try to avoid staying under the sun from 10 a.m. To 3 p.m. When its rays are its fiercest.

• Wear clothes that are cool and light. Cotton allows your body to breathe and light colors do not absorb heat as much as dark colors.

• Don't forget to apply sunscreen even when the day is overcast. Sunburn affects your body's ability to stay cool.
