Preventing Post-Race Illness
Why do I always seem to come down with a cold a couple of days after an intense race?
Heavy endurance exercise increases stress hormones, suppresses the immune system and increases risk for dehydration. Illness may be related to immune changes during and following heavy exertion (between three and 72 hours after). Viruses and bacteria can gain a foothold, increasing risk of illness.Keep your immune system "in shape" by:
• Minimizing stress levels
• Following a well-balanced diet
• Resting sufficiently
• Staying hydrated by drinking sports drinks before, during, and after exercise

Preventing Illness During Training
What are some ways I can prevent illness during training?
There are several practical recommendations endurance athletes can follow to help ensure they stay healthy during training: (1) keep stress levels to a minimum; (2) follow a well-balanced diet; (3) get sufficient rest after a workout; and (4) avoid exposure to viruses and pathogens (e.g., wash hands, etc.); (5) drink a sports drink containing carbohydrates before, during, and after prolonged and intense exercise. In addition to keeping you hydrated, sports drinks contain carbs that help to reduce stress to your immune system.
