Over the last couple of years i’ve become prone to sinus infections and sinusitus (anyone who gets these will know how bad they can make you feel). The thing is, I find that when I run I tend to have far fewer sinus issues. On the other hand, when I don’t run for a couple of weeks i’m more likely to start feeling Sinus pressure build again.
I’m guessing that the motion that takes place when I run might actually be helping to clear my sinuses - which for me is a real benefit
Out of interest: Does anyone else have similar experiences??
