I wonder how this might figure in relation to PoTS (postural orthostatic tachycardia syndrome), either way
PoTs being where the autonomic system doesn't equalise blood pressure, especially when standing up n still for several minutes, this the brain doesn't get enough oxygen, so brain fog, head rushes, grayouts (and fatigue, temperature dysregulation + intolerance)
(I've the hyper-adrenergic variety, hyper-PoTS, where the brain tries to generate pressure in a way that will never generate pressure, leaving it so frustratingly easy to have adrenaline rushes that can last for hours)
I've seen a PoTS professional describe the effects as like kind of a mini stroke
it's getting more attention now due to the long COVID relation, and it seems that maybe microclots have become a prime suspect as a possible cause to many symptoms, though there's so many jigsaw pieces, and discerning correlation n cause n effect etc..
obviously there's many contextual tipping points between that and this study (if generalisable)
apparently I have a strong heart. idk
related;
I've nostrils with the collapsing innner valve, so I can't get deep breaths through my nose (and got getting enough air whilst sorry l asleep is a cause of bruxism)
rhinoplasty then turbinate reduction helped mildly, but apparently having some cartridge inserted would help prop the path open for a more normal use.
so,
both of these leave me feeling out of breath a lot
and it's why I'm a month breather. hopefully a third bit of surgery will finally properly help
some kinda vague anecdata there, some kind of a lens anyway!
