Can exercise protect me from a cold or flu – or make me more susceptible?
Although people who exercise regularly generally get sick less often, sometimes too much of a good thing can be harmful. Some studies show that intense exercise—like a two-hour run or grueling gym workout—may make you more vulnerable to viruses. This is because after you exercise vigorously, your immune system becomes stressed and weaker for several hours. So be extra-careful to avoid germs during this time. And also be sure to squeeze in at least a day or two between workouts.
What about working out in the cold?
The notion that cold or rainy weather ups your chances of an infection is a myth. So in general, it's safe to exercise in cold weather as long as you're properly dressed. Cold-weather attire tips:
- Dress in layers to avoid overheating
- Avoid cotton clothing, which retains moisture and may make you colder once you start sweating
- Opt for synthetic fabric, such as polypropylene, which wicks away moisture
- Cover your head, neck, hands and feet properly
If I'm sick, when should I take a break from exercise?
There's really no right or wrong answer for this question – it all depends on how you feel, which is why it's important to listen to your body. If you have a cold but your symptoms aren't too severe (i.e. runny nose or sneezing), it’s usually fine to stick with your fitness routine. Try not to overdo the workout, though – it may worsen your symptoms and in some cases lengthen the illness. If you're feeling less than 100 percent, stick to light-to-moderate exercise (e.g., walking) until you start feeling better.
But if your cold is accompanied by a fever, chest congestion (making it hard to breathe) or flu-like symptoms, it's best to sit your workout out for a few days until you're feeling re-energized.
How can I avoid germs at the gym to avoid getting sick?
Gyms are a hotbed of germs. Some of the tops spots where cold and flu germs lurk are interior door handles and gym equipment (think dumbbells, free-weight benches and cardio and weight-training machines). And while most germs won't make you sick, it's better to be cautious.
Check out these tips to avoid gym germs:
- Bring your own water bottle and avoid the water fountain.
- Shower or wash your hands with antibacterial soap before and after hitting the gym.
- Avoid touching your eyes, nose or mouth.
Wipe down gym equipment before and after use to avoid the last guy’s germs, while also leaving things clean for the next person.
