Not a guarantee but a good place to start. Why a low tolerance to Co2 creates a feedback loop with feelings of anxiety & panic, racing mind, sleep problems etc - Co2 is the driver to breathe, or in a lot of people over breathe. Breathing rate at rest is one of the main things that will influence the state of the autonomic nervous system. When someone over breathes they have short, shallow, erratic breathing & hold the breath without realising, when the breath is held (this also creates physical dysfunction) and there is a low tolerance to Co2, it doesn’t take very long for the body - the internal environment, to go into a panic and give you the urge to get rid of the build up as it is threatening & uncomfortable, it wants to go back to comfort which in the case of low Co2 tolerance is dysfunction mentally & physically due to the breath & relationship between oxygen & Co2. Co2 being the driver to breathe combined with a low tolerance to it causes the person to constantly want to off load the build up of Co2 through a gasp or sigh and go back to short, shallow breathing & not expose themselves to the higher levels of Co2 in the lungs & blood - so what the brain tells you to do is the exact opposite of what you need to do. Co2 is known as a metabolic stress messenger, so with physical, mental, emotional strain the tolerance will vary day to day. That’s why building Co2 tolerance is also building stress tolerance. It will affect the physiology of the entire body & can be applied to so many situations, one of them is calming the brain & body through short periods of air hunger & coherence with breathing.

Something briefly on this example - our first session was a score 5-6s, now at 40s +. Vomiting from anxiety stopped after first treatment where we tripled the bolt score. Sleep, energy, appetite all doing very well now. They also bought the headset to use daily which is phenomenal for sleep & brainwave entrainment. Feelings of anxiety etc aren’t the problem they are just feelings aren’t necessarily bad or good maybe a signal of the internal or external environment.

Watch the depth it will pull, even towards & down the spine. That will have a cross over effect to the opposite hip or with the same side down the full lumbar spine & pelvis. Along with that the difference in how well the scapula moves as it’s clearing restrictions with so many tissues under the shoulder blade & into the ribs. With the lat and the effect on the pelvis, spine, scapula & arm it will free up the T-spine massively.

Saves hours spent on scapula & spine mobility, especially when followed up with some basic reduced breathing to bring more diaphragmatic breathing & intercostals, as it’s your breath that will be largely responsible for organising the spine & ribcage

Both sides treated at the same time along with the hamstrings. GAA athlete

Came across this post although I can’t find the original page it came from. I tend not to read too many studies I prefer books and first hand experiences with the full story, but I found this pretty cool with my own experience with Parkinson’s last year.

I’m in no way saying it was a fix or cure, but step back and think how long it would take for a neurological disease to set in & take effect to the point it’s all day everyday - compared to one hour of focused treatment in clinic, enough to visibly stop the tremors that where constant. Breathing cadence, Co2 tolerance intervals, 7.83hz lightly travelling through the body with microcurrent. If I had molecular hydrogen inhalation therapy back then I think it would have been even more positive.

If 60minutes could do that, compared to years of the condition developing, surely there’s far more that can be done.

Even if you only look at breath, without spending thousands on equipment. Blood flow, lympathic flow, cerebrospinal fluid flow are all moved by the breath. You can look into cerebrospinal fluid & the glymphatic system of the brain. Blood flow & oxygen delivery to the brain, focus on making use of Co2 & nitric oxide. Aswell as the effects on the ANS & vagus nerve. And it’s all right there at your nose.

All of that is massively beneficial for sleep aswell which is the main thing, as that’s when the brain will have the most rejuvenation & clearing. Also why snoring or mouth breathing at night which disrupts your sleep should be a concern for people who care about this, as you skip the nose.

64 years of age & packed away the CPAP machine. If you’re on one of those or know someone, if you’ve 4minutes listen to the improvements that are very doable for majority of people. Years of sleep struggle & snoring, CPAP for 8-9months, off it in 7weeks after 3 appointments

Follow up is in two weeks time & also started them on their molecular hydrogen inhalation therapy from today onwards in treatment, which is going to have even further improvements for massively reducing inflammation, improving circulation & definitely benefits for the respiratory system

Snoring is not normal. Struggling to sleep is not normal. Needing assisted breathing is not normal. Your body is trying to tell you something

Breath holds on the assault bike, very easy way of using a form of hypoxia training. Which is training in lower oxygen environments, and creates very beneficial adaptations in your cardiovascular and respiratory systems, all through the breath

That’s followed by decent enough efforts pace wise but keeping the breathing as light & quiet as I can, to keep improving the tolerance to Co2 levels in the lungs & blood, again combined with increased uptake of nitric oxide by not using the mouth it’s unbelievable for blood flow & circulation throughout the body & brain

I don’t train for anything or do any one off events, just general health & having a very high tolerance to Co2 which will directly lower breathing rate at rest as Co2 in the lungs & blood is the driver to breath when you have a low tolerance. I’ve said for years unless you are a top level athlete with a one off event coming up, there isn’t many reasons to not completely switch to nasal breathing for all cardiovascular work, take a step back & build a very strong Co2 tolerance base & build from there, other than it can be very uncomfortable in the initial stages

Sessions was 5 rounds breath holds on the exhale, I do different variations & pace/time. Into 20:20 for 5 rounds then 5:10 for 5 rounds. There’s a lot of reasons not to do holds or air hunger so make sure you’re read as much as possible before doing any of it

Photo on the right eating 2500cal everyday now, still training two hours per week as she has done for the last seven months. 2/168 hours per week. Il use Cats change as an example, when it boils down to the simplest thing it’s just not making excuses, it’s your own choice what you do

It’s not the easiest part for a lot of people but I do believe when you make that decision in your head & change your mindset on how you view yourself well then enjoy it, look after your body, it’s a gift if you’re in the position to even do that

Main thing is enjoy yourself have a good time do what you want. Just don’t complain about it or take the p**s eg out on a Friday, still using it as an excuse come Sunday about falling off track, there is no track. If that’s what your deciding to do then just say that don’t pass blame

Training wise, she works two jobs, full time Monday to Friday then part time evenings & weekends. So quality over quantity, sessions haven’t changed much as we only use kettlebells, barbell & DBs and a bench. Just good quality training, recovery, repeat & progress

GAA athlete picked up an injury mid game. Sharp pain putting weight through the foot standing & walking, wasn’t able to run. First treatment was the Achilles which was torn 4years prior, thick scar tissue, stiff etc. Treated calf, ankle, foot also

Huge decrease in pain over the next 24-48h. As a bonus achilles was no longer stiff in the mornings, said it usually took him 45minutes after getting up for the area to free up

The injury was very close to Achilles on the inside of the ankle but I can treat scar tissue & inflammation at the same time so we went with that. The dysfunction in the tissue around there & the scar tissue will have been causing such problems for the ankle in general - the restriction through the whole area & the electrical barricade the thick scar tissue would have created. Moved on from the ankle area to treat sole of the foot to behind the knee in the same treatment as part of the back line

Second session a week later. More of a full body. Worked through the ankle/achilles again & hamstrings | lats | shoulders all at the same time. Then moved into the front of the pelvis & core treating the upper quads as he had torn them in the past, hip flexors, groin & adductors, lower abdominals

Missed one game & back to training

Inform me brother. Every opportunity for a sunrise

A lot more training now with the longer brighter days. More weighted push ups, chin ups/pull ups, heavy kettlebell swings & presses and volume than I had been doing. Not following a set plan or sessions for now. Also more volume means more than one day a week so probably not that much

Have been doing two, sometimes one large meal per day. Usually starting the day with fruit as it’s easy & light then the big meal around noon. Haven’t been eating at all after 6pm

Honeymoon material. Easy carb sources. Nitric oxide. Raw honey as it’s the greatest of all time

Of all the books I’ve read on breathing this is my favourite. Wrote in the 1800s, just a guy writing what he seen when living with 150 different tribes to compare them to the what civilised life was. A lot on food, sleep but mostly how they breathed

Everything he wrote, science, studies, data etc all caught up

Lived & haunted with tribes, who wouldn’t speak a word or open the mouth to breathe for days on end running as mouth breathing was considered a sickness

Mothers would sit up to watch babies at night to make sure mouths didn’t open & close them shut if they did

Even talks about digestion issues & calming the nervous system

Max effort sessions like this are the only time I’d use mouth breathing. Sprints with very little rest periods. I don’t play a sport or do long distance runs but there’s a way everyone can bring into there training & lifestyle

If you aren’t a top level athlete with a one off event in the next few weeks, I’d 100% recommend committing and training nasal only across all cardiovascular work, including high intensity, just adjust the pace. If you’re just training for enjoyment & health like the majority there’s no reason not to

Pitch based sports incorporate it mid week & huge benefits warmups pre training & pre games. Game time it’s a one off event do whatever

Mouth breathing you’re doing yourself quite a disadvantage and will by default create dysfunctional breathing to some degree. Not only in your capacity, remember Co2 is produced by working muscles not just your breathing rate, if you have a very high tolerance you reduce the panting effect to off load it, higher Co2 levels result in faster release of oxygen to the body, you also absorb more oxygen, combined blood flow benefits from Co2 + nitric oxide, which you by pass by mouth breathing. If you have a very high tolerance you automatically have very efficient breathing mechanics - breathing effects you mechanically, chemically, psychologically.

I’ve been posting this for years, take it with a pinch of salt, it doesn’t mean you physically shouldn’t open your mouth during effort, but strip it back, why do you have a nose

It’s more the effect outside of training from building a very high tolerance - lower breathing rate, more oxygen absorption & blood flow (body & brain), calmer, better sleep

Session was 15cal sprints you go I go 4 rounds. So about 20-25s rest between. Short max effort interval. Lungs & fatigue hit quick
