Looking for a video/sound which is just someone continually deep breathing

I’ve been thinking of what I want to do to prevent screen apnea. I want to try to listen to a track where someone just deep breathes continually so that I can mirror it and listen to it while I work.

When I search for it tho I only see videos of people teaching breathing exercises. Anyone know of a video or track that is just simple deep breathing or what to search for to find it?
