David, yawn is the deepest conscious dilation one can do without a lot of yoga practice. And yawning needn't just take place where it normally takes place...with practice, the move can be directed just about anywhere. It's a helpful move to direct to achieve a temporarily opening at a block....sort of a foreshadowing of how things will feel after mantra and/or asana has more deeply and enduringly worked on it. When parents teach kids to clear ear pressure via yawning and swallowing, they are, yes, teaching them a yoga move.It's not the yawning that does it, per se...it's the yawning-ness. And that's what I'm suggesting here, as well. Don't just yawn, but dilate the exact spot at the base of the throat, front of the collar bone, with a yawny feeling.
Scientists don't know why we yawn. I'm increasingly convinced that all the things which strangely elude scientists about the human body and its energy, etc, are energetic-body yoga issues. For example, shivering, laughing, and crying - all mysterious to science - are all telltale yogic diaphragmatic contractions which evoke a tiny spray of healing/energizing/consoling kundalini. That's not gonna come up via research!

The dilation strategy I wrote about seems to create a strong temporary unblocking at the front of the throat chakra (and, yes, it works on any chakra, but even I, who is way more on the hatha/hacking end of things than I probably should be, refrain from working under the hood unless there's a serious problems). I'm not sure, however, how much enduring help it brings. That remains to be seen. But if you have migraines or TMJ, even temporary help is a godsend.
And yes, energetic throat block is, in my mind, unquestionably the cause of snoring and sleep apnea (neither at all understood by medicine, btw). And it's also, I'm pretty sure, responsibile for a lot of kundalini syndrome issues....hence this posting:
http://www.aypsite.com/plus-forum/index.php?topic=3296I do have snoring and sleep apnea, and am doing this practice just before sleep. I'm not sure how far into the night the effect extends at this point. Work in progress! It may also help with tinnitus and glaucoma, I'd imagine. Though tinnitus is touchy....if you open a throat block and more energy coarses thru head, that can increase ringing in ears - a standard kundalini symptom.
The practice you suggest will surely help. People with front channel block at throat tend, posturally, toward jalandara bandha (when watching tv or reading, I slump way down in couch until chin just about hits collarbone). So anything that keeps the head at a greater angle while sleeping is good (I think that's what's happening here,, just via gravity of the body pulling down).
