So I searched and searched and what I came across that sounded like the best shot was simply: breathing
I experimented and it worked.
Here’s a little background though. I’ve been practicing breathing through my nose while running for a couple of months now and also realized that I’ve been nose breathing often when doing push-ups. (These are my 2 main exercises that I do everyday without fail.)
I would inexplicably almost always have my ears clogged after some exercise. Now I know why…
I don’t think I was breathing enough.
So what’d I do? I started breathing more. Even to the point of exaggerating my breathing a little (through my mouth especially).
The result: no more clogged ears! YAY!
So in summary: Breath (enough) when you exercise. 🙂
