Answering questions about exercise during cold & flu season

This is one of the worst cold and flu seasons in a long time, with many agencies actually running out of the flu vaccine.
It’s prompted many people to ask this question: “What role does exercise play in helping to avoid getting sick?”
And this is the natural follow-up query: “Should you exercise if you have a cold?”
You have questions, I have answers.
Exercise and the immune system – Doctors widely report that regular, moderate exercise helps jump-start and strengthen the immune system and in turn fight off basic infections such as colds and flu. Of course, most people know that exercise also helps fight off major health problems such as heart disease, high blood pressure, osteoporosis, Type-2 Diabetes and even some forms of cancer.
Exercising with a cold – Here are things to consider in deciding if you’re well enough to exercise.
A mild to moderate workout should be all right for people who have a cold, but no fever. In fact, exercise can even help someone feel better by temporarily relieving nasal congestion.
My doctor said a quick rule to remember is to go ahead and exercise if the signs and symptoms are “above the neck,” like sneezing, sniffling, runny nose, sore throat.
If the ailments extend “below the neck,” it’s best to postpone the workout for problems such as chest congestion, deep cough or upset stomach.
Also, put off your workout if you have a fever, fatigue or widespread muscle aches.
If your “below the neck” symptoms are there, but minor, you still might choose to work out. If you do exercise when sick, use common sense and listen to your body. If you start feeling worse while exercising, then stop.
When you start feeling better, gradually work back into your regular workout return.
Please keep in mind that if you are using cold medications such as decongestants they can increase your heart rate. Since exercise already increases your heart rate, this can be a double-whammy on your heart so you probably don’t want to work out as hard. You could become short of breath and have trouble breathing.
And one final piece of advice from my doctor: “Wash your hands frequently. It’s the No. 1 way to reduce your risk of catching a cold.”
