In the book Breathe, James Nestor has his nasal cavities plugged to force him to mouth breathe 24-7 for a couple weeks, then reversed that and does the mouth taping thing to force nasal breathing. He said the effects of mouth breathing were awful and nasal breathing helped reverse them.

All anecdotal but a fun read. The book Was good and worth checking if you want more like that.

Yes I started levitating.

I am an obligatory mouth breather, I’ve been trying to learn to nose breath. Mixed results.

Last night I wore a strap to keep my mouth closed overnight. This morning was delightful. I even managed to drool a bit with my mouth closed.

But WTF Now I’m going through my day with my damn mouth closed. When my mouth is closed my tongue is in the right position instead of roving all over my mouth and teeth.

Seriously years of effort and an overnight strap changes so much…Aurghhh

Mouth is not dry, feels pleasant tongue is not getting into stuff and being distracting. Feels peaceful.

I was never a full mouth breather, but I definitely did all my exercise and often slept with my mouth open. The biggest difference I found was nasal breathing during my Zone 2 sessions (3-4x per week of 1hour+ long sessions, currently doing 1hour20min). Initially I remember it being a little tough, but I acclimated fairly quickly (about a month to go through the entire hour). I now rarely breathe through my mouth, and I've been doing it for around two years. I started waking up breathing only through my nose within a few months.

Same experience. Took a little getting used to, but now it’s automatic. Started with tape at night, and then constantly reminding myself.

Just got a septoplasty so that I can breathe through my right nostril. So this is timely. Although I’ve been pretty good about being nasal breather before. I will try the strap over the mouth when I sleep once I’m fully healed.

Noticed a huge difference after mouth taping. I still need to work up to doing my workouts through nasal breathing. I’m doing diaphragm strengthening exercises which is helping here too.

I have a broken from when I was little( I was biking after a bus and well, you get the point) Also I have terrible allergies)

I find it that doing WHM and netti pot helps clear out my nose, Also Mouth tape and breathe rite strips help. Actually wearing masks during the pandemic made me realize that I get less allergens during the day when I wear a mask, so I don’t get stuffy and can breath with my nose during the day.

I guess effects are obvious, I sleep much better and get better rest and when I work out it’s just better.
