There's been a lot of recent interest in mouth taping during sleep, which can help alleviate issues related to mouth breathing or snoring. Anecdotally I've seen improvement in overall sleep quality (quantified w/ a wearable device) when I use tape vs without.
I had a runny nose most of my life - diagnosed allergies and etc.
One visit in laryngologist got me thinking; he said: "It's simple. Wet wounds heal fast and well. Dry ones can even not heal at all. You have dry lung mucosa and that's why you get infected easily: it's like an open wound".
He was right, after keeping > 50% humidity around myself I got better. That got me thinking of experimenting more.
What if, I had a running nose, because the body wanted to make my lungs less dry? So I forced myself to breath through nose for two weeks and again, got better. Still doing it, years after.
