For what it's worth, this guy discusses hypoxia in this video:I don't think so but the fullness in the ears is what concerns me (on top of the tinnitus).
I am hoping to see an ENT tomorrow, though I don't know how much they could possibly do at this point.
I hope this is the case and that it can be resolved; however, it seems more likely that the hypoxia caused some damage. I'm just in shock how a breathing exercise put us in this predicament.
Keep in mind, he's a Wim Hof instructor and avoids any mention about the negatives of inducing hypoxia as part of the breathing method.
Thanks for all of that information. It's very interesting.CO2 concentration will cause vasoconstriction or vasodilation depending on the tissue, and also acidifies the blood making hemoglobin change shape and "let go" of oxygen more.
Lowering it undoubtedly would cause vasoconstriction in smaller arterioles as well as no change in oxygenation to tissues.
Cold also constricts smaller vessels severely so you stay conscious, like in your inner ear or fingers when subjected to hypothermia.
So no, you haven't "upset your ionic balance" in your inner ear, you don't have Meniere's. It doesn't fit anything.
You literally caused from synergistic cold and hyperventilation rather impressive vasospasm, abnormally strong binding of O2 to blood (not to where it needs to go, the tissues), and slowing reactions with colder blood / the cell needs to keep up to survive (ATP production) ultimately would kill off highly metabolic aerobic cells (aka the 10k+ hair cells). So, you have high pitched ringing now. Yes it can be somewhat reversed with time.
It's why if you get hypothermia or pass out you may feel ringing in your ears during the episode until you warm up so it's "temporarily" because you didn't do massive damage... but there's only so many cycles of that nerve cells can take, especially ones that are barely fed enough and are highly metabolically active.
Lower frequencies though more vulnerable to vasospasm don't seem to use as much O2 (so I'd guess it takes longer to kill those off if conditions are kept the same).
Our bodies detect CO2, NOT Oxygenation, is part of the reason why hyperbaric oxygen is rarely helpful (basically only in stroke or necrosis when there's no other way to "get oxygen" there, those blood vessels in your ear didn't die off by noise or meds) and can be toxic as our bodies won't regulate too much of a good thing if it comes to that (seizures / oxidation of membranes).
There are benefits to cold, and starving some tissues of some O2 might be beneficial, but you're going to kill cells along the way.
Question: What if all people did was the breathing exercises and did not expose themselves to a cold shower? Many of us have developed the high pitched ringing after the forced exhale and breath hold, followed by the inhale and 15 second hold without taking the cold showers.
Many of us also feel a certain blockage or fullness in our ears, or a sensation like the ears won't pop. What do you think could be causing that?
In my case, I went to an ENT and audiologist and they found nothing wrong. The ENT's only guess was that I had inflammation of the inner ear and he said it would go away with time. Many people have this high pitched ear ringing for months after first contracting it from Wim Hof breathing. For some people it resolves on its own within a few days, some within a few weeks, and others it could last for months. I'm very curious as to why this is. It would be amazing to speak to someone who did Wim Hof, had the lingering tinnitus and then recovered from it, just to hear their story.
