Health Tip: When to Skip Your Workouts
|
(HealthDayNews) -- Do you believe that a cold or the flu needs to be sweated out in the gym? If so, you''re mistaken. Your body doesn''t sweat out toxins during exercise, according to the War Memorial Hospital in West Virginia. Rather, your immune system fights the better fight when it''s not stressed. Moderate exercise can help boost your immune system, thereby decreasing the chances that you will catch a cold or the flu. But a hard workout when you are sick can impair your immune system for several hours, making your illness worse. Once you''re feeling better, give your body an extra few days to recover before you resume working out. Allow three to four days of rest after a bad cold, and at least a week after the flu. When you return to your routine, practice the 50 percent rule. Decrease your usual exercise time by half and go half-speed on the treadmill or exercise bike until you regain your strength and endurance.
