A friend of mine started "blowing air into water with an straw" (making bubbles) very seriously. I was very skeptical to say the least; but after a couple of months the effects have been very eye opening. Not only it has helped sleep apnea and snoring but also helped with reducing their weight. They had an online group and most participants reported the same. The wight loss was reverted when they stopped for some personal reasons. I wonder if making bubbles in the water has the same effect.

I don’t mean to be rude, but what kind of personal reasons might stop a person from breathing into a straw at night

CPAP machines are essentially a hose that has you breathe into water.

My didgeridoo teacher had the class practice at home continuously blowing air through a straw - it still took me almost half a year to reliably be able to do circular breathing.

I have read a few references that humming or ‘ohming’ help sinus health and breathing so I guess it makes sense playing the didgeridoo would help also. Blowing bubbles through a straw won’t cause vibration, so probably in itself won’t help.

Someone really needs to properly do the science on this

I (presumably like the majority) assumed that sleep apnea was at least partially caused by weight gain, but if there is weight gain caused by sleep apnea it’s going to give doctors some new tools

Reminds me of that guy who started drinking water upside down to train his swallow muscles and cure his chronic heartburn.

Is the weight loss just from sleeping better and therefore making better food choices?

Just learned from comments here it's called "circular breathing"!

I saw a documentary where a vocal coach used a similar technique to help metal singers sing in a way that didn't destroy their throat and vocal chords

Can you please expand on that? How many times and minutes a day? Full power?

Got a link?

Seems related to our aquatic mammal past.
