Swimming with a cold might be OK but know the risks for you and for others
There are times of year when it seems nearly impossible to avoid catching a cold or the flu. Everyone in the office and at your kids’ school is sick and you’re bound to catch something. You might need to stay home to get better and to avoid giving your illness to other people. But you might also feel like there’s no need and you want to get back to swimming.
There are some issues, though, with swimming with a cold. And in addition to worrying about your illness and exercise, you should take into consideration the chance of others catching your cold.
