Potential health problems of mouth breathing or taping to combat mouth breathing? From my reading it sounds like if you have any kind of respiratory condition - asthma, sleep apnea, even allergies then it could be risky.
(I can rarely get congested to the point of not being able to get enough air through my nose in the middle of the night without warning so I feel like I could suffocate if I tried this, plus most nights I'm able to nose breathe most of the time anyway)
Does the other iOS user have 18? I'm the 1 android user in a 3 person group chat and I'm wondering if I should try to get one of them to update.
