1. The “below the neck” rule.
I’ve read in more than one place that, if your symptoms are below the neck, don’t run.
Chest congestion or a bad cough means that your respiratory system could be compromised if you run in that condition. You could contract strep throat, bronchitis or other nasty things, so stay in bed.
If your symptoms are above the neck, however, like sneezing or a runny nose, it’s probably OK to go for a jog.
Do an easy run and see how you feel.
Pay attention to your body and note how it responds.
