Kids have been doing it very badly and unsafely in the form of "The Choking Game". Let me make it clear at this point that THIS IS NOT THE SAME THING AS HYPERVENTILATING! It is also NOT THE SAME THING as holotropic breathwork! Such methods I have found rarely bring about such profound shifts of consciousness in such a short period of time.
By holding your breath after briefly hyperventilating you can change blood flow in the brain and temporarily disable certain areas to achieve a state of euphoria.
I have looked in to the health safety of this technique with the aid of briefly asking two doctors, one neurologist and asking a medical forum and have got the all clear within certain respectable ranges and considerations.
Below is the method that has been confirmed safe to me by medical professionals from my research.
1. Breath deeply and fast for 5-10 breaths or longer until start to feel light headed.
2. Hold your last breath in for 4-5 seconds. Keep your eyes closed the entire time.
3. You will start to feel relaxed and notice the profound change in awareness that last about 10 seconds (30-40 on dmt)
I want to make it clear that this method does not suffocate the cells of oxygen as holding the breath for that amount of time is proven not too, this is why swimmer do it all the time doing long distance underwater swims.
Obviously, if you do this long enough you will pass out and risk harm to yourself as the doctors informed me of, even though this carries the same risks that are associated with any form of choke out (mma) which most seem to recover from unharmed. The distinction to make here is that oxygen derivation is detrimental to the health of brain cells so this is not to be confused with the choking game which teens have been doing for decades to feel a euphoric rush. That is extremely dangerous and I do not advocate it.
Basicly, by allowing the blood to be more alkaline via respiratory alkalosis it constricts the blood vessels and allowes the blood to pool within the brain and suppresses activity in certain areas, therby altering awareness of self and the environment.
Note:
Do not stand up at any time before or after. Make sure you are in a safe environment. If you can be still and do not touch anything with your hands.
If you hold your breath longer than 4-5 seconds, the effects will be diminished and this is where the medical professionals agree that less time you hold the safer it is.
If you want to feel stronger effects you can repeat step one for 20 breaths but unless you are accustomed you may risk passing out.
The difference between doing this straight and whilest on DMT is extrordinary, I felt my body in a way I have never felt it before.
I also want to add that I in no way promote this as a risk free activity, just like no one promotes psychedelics in that way either. For me it has been a tool to explore my mind and afaik has not caused me any problems after 5 years of weekly activity.
If anyone would like to chime in on the neurological functions of what is occuring here I would appreciate it. If I had to take a guess I would say it feels like the frontal lobe activity diminish and areas of activity in the mid brain are altered, places like the thalamus that routes sensory signals to intergration areas. Also feels like the DMN (anterior cingulate cortex) is being deactivated because I can tell when DMT does this to me very quickly and feels exactly the same with this technique.
