Heat injuries range from mild forms to more serious types, including heat exhaustion and heatstroke.
Heatstroke — when the body's sweating mechanism quits, the skin become hot and dry, and the body loses most fluids — can be life-threatening.
The American Academy of Orthopaedic Surgeons offers these suggestions for exercising safely in hot weather:
- Drink plenty of fluids even when you're not thirsty, and take frequent breaks during exercise.
- Get your body in good shape before hot weather hits.
- Limit outdoor exercise to early in the morning or late in the evening, avoiding the midday hours.
- Exercise more slowly and less vigorously for longer periods.
- Wear lightweight clothing, and avoid heavy gear.
- If someone looks like they're having a heat injury, seek immediate medical attention.
