that youtuber huberman also suggests for similar things "physiological sigh" which i have almost fully conditioned myself to use

it's like, you are breathing in, and then you suddenly suck in twice as hard

only takes a few rounds

according to this huberman, it has a dramatically high success rate at reducing anxiety, i think my own experience validates this, to the point where anxiety is no longer a problem for me at all, only depression, i observe myself doing this second suck-in unconsciously all the time so much it is clear i have programmed my nervous system to do this automatically now

if you have ever lived with dogs, you may have heard them do this double-breath thing, i always used to find it odd, but now, i do it!
