Just straight here. Being stressed and needing fresh air are not problems, just go and get them, find your pace.
Secondly, assuming poker is your job or your main source of income as otherwise you wouldn't be asking this, it depends how obsessed you are and how much you want to achieve and succeed. If you'd rather be stuck in a job for 8-12 hours without an option to get fresh air, then go for it. Poker is not an obligation, it's a choice..
If it's just a hobby, then it's even more of a choice so stepping away from it does not affect your well being..
