Can it help? Sure thing.
Frequent exercise, even outdoors when it is chilly, may protect you against catching a cold by strengthening your immune system. In an eight week study, people who did 45 minutes of moderate-intensity activity a day, like riding a stationary bike or walking briskly, got sick about 30% less than people who remained sedentary.
Already feeling under the weather? Experts say it’s safe, and even beneficial, to keep working out if your symptoms are from the neck up 9sore throat, runny nose, or headache). But take a rain check on Zumba-ing if you have a fever or body aches. Head to bed instead.
