I’ve actually always wanted to know the answer to this one, so thought I would do a bit of research on it and find out if you should workout when sick. Here’s what I found:
1. If You Have A Cold
If you just have a regular cold (sniffly nose, sore throat, etc), then light exercise is fine. I wouldn’t push yourself too hard, especially when breathing through your nose is hard. But something such as a lighter weights session, power walk or pilates class is fine. This will help your immune system and also help you sleep better. But just remember that colds are contagious so be as hygienic as possible if you are working out at the gym.
2. If You Have A Fever Or The Flu
If you have the flu, or even a cold with a fever, don’t exercise. This could make things much worse and you are better off staying in bed. If you exercise during this time, it will prolong your sickness. And it can also lead to a whole range of issues such as severe dehydration, inflammation of your cardiac muscles and even death. Just stay in bed!
3. If You Have A Stomach Bug
Vomiting and diarrhea aren’t fun and I don’t think you would feel up to exercising anyway. But just so you know, it is best to avoid exercise at this time too. You will already be dehydrated so you don’t want to make things worse!
