Don’t go another moment breathing like this.

Your videos are super informative and your presentation is awesome, keep it up man it's quite enjoyable getting proper information. Thanks for the content.

I absolutely HATE having to breathe through my mouth. When allergies or a cold gets me I'll sleep sitting up so I don't mouth breathe. It messes up a lot of things and it causes terrible cotton mouth and allows bacteria to grow rampant in the mouth. I had severe asthma and I was taught to breathe in my nose and out the mouth. Swimming free style helps with learning to breath with more control. I recommend it for anyone who has asthma. I haven't had to use an inhaler since high school, I am 36 now.

As a Czech, I love the mention about Emil Zátopek! 🏃🏃🏃

We got sun breathing in real life before GTA 6

I love how you break this stuff down. I appreciate you.

Currently binge watching all your content

Lab coat may not be required, but a high school education mght be. Breathing is controlled autonomically ( look that one up , genius ). Breathing is controlled by blood , blood blow, , blood pH and and primarily ( in normal persons ) by the CO2 content in your blood. Which pipe ( Mouth or nor the air pases through is irrelevant to your overall cardiovaculatr condidition . Yes, chronic mouth breathers have more dental cavities,dry mouth and bad breath. However, the usual rate and depth of breath and thus gas ( oxygen-CO2 ) exchange maintains your blood pH , and proper cardiac function. The difference between inhalation and exhalation is due to the interaction of the diaphram and the elasticity ( compliance ) of your lungs.
If you try to "control" your breathing , you could do so for about 5 minutes, then the central nervous system will take over and you will either become very uncomfortable or , if you can't breath as you are designed, you will be in big trouble and end up on a mechanical ventillator.

50% is a crazy number I never would have guessed. I suppose I should be thankful this has never been an issue for me. I dig your stuff, Johnny, thanks.

I've laughed way too hard on the "but, but, but" part

yeah know, about 2 years ago i watched a video that talked about how its better to be exclusively nasal breathing. Even during intense exercising. So I tried it. Ended up with a sinus headache for 3 days. I'm gonna keep breathing through my mouth and nose while exercising, thanks. (But also, isn't hyperventaliation a symptom of anxiety? You make it sound like hyperventaliation is causing all those other symptoms, when it's just fun partner to all of them!)

Had an anxiety attack last night and deep rhythmic breathing worked a charm. Rubbing the neck to stimulate the Vagus nerve helped as well and felt good! Lotta tricks in the arsenal but, breathing is by far so much more effective.

Heard nose breathing also helps with nitric oxidide production so yeah 🍆

I've watched a few of your videos just found your channel. This video is so fun, I truly enjoy the more methodical detailed newer vids but this one was fun! ❤

My epiphany was when i realized that we dont breath in oxygen and breath out co2. We breath in and out a mixture of both to maintain a certain concentration of both in the bloodstream.

Wait… I tend to freeze when I'm stressed. And to hold my breath.

That's all well and good, but my nose is half busted. It's usually clogged. And I've been dealing with this breathing issue for years. I guess I'll have to get surgery because just re-training my breathing is not going to be enough. Thanks for the explanation though because when the therapist suggested hyperventilation syndrome, she didn't explain it well enough for me to believe her. Two thumbs up!

I've always breathed slower than others. Almost holding it at the bottom already.

I am rooting for this channel to do incredibly well in the future.

This is why every generation living together for centuries was so important. Think about how many things like this have been found and lost over and over.

I'll just come out and say it…..If someone told me, a late middle aged white feller from the UK, that this morning I would stumble on a YT channel of a switched on young American black man giving me well informed health advice I'd have quietly thought "yeah more chance of me running naked down the middle of the road where I live".

I'd best start getting stripped off now…. and its bloody cold outside.

Great channel, and a great role model, feller.
