![]() ![]() It was found he could withstand extreme cold for unusually prolonged periods, and could also mute his immune response while using the breathing technique in a controlled setting. entheogenic-gnosis, a BBC documentary "Incredible Medicine: Dr Weston's Casebook" aired very recently that look at Wim Hof's breathing technique in some detail. egĪum_Shanti, no worries, I thought it was interesting, and yeah I too thought that high CO2 levels was more of a trigger for the flight or fight response. I have had a cold for the last few days, and am pretty groggy as a result, I apologize if this has affect on my writing. the thalamus and anterior and posterior cingulate cortex (ACC and PCC) and the ACC/medial prefrontal cortex (mPFC) are all areas of the brain which are also affected by ingestion of entheogens, such as psilocybin. This overview highlights the involvement of multiple neural structures, the neurophysiological and neurochemical alterations observed in meditative practices. The neurotransmitter changes contribute to the amelioration of anxiety and depressive symptomatology and in part explain the psychotogenic property of meditation. The neurochemical change as a result of meditative practices involves all the major neurotransmitter systems. Neuroimaging studies have shown that meditation results in an activation of the prefrontal cortex, activation of the thalamus and the inhibitory thalamic reticular nucleus and a resultant functional deafferentation of the parietal lobe. The available data on meditation focus on activated frontal attentional network. The evidence though preliminary and based on studies replete with methodological constraints, points toward the involvement of the prefrontal and parietal cortices. The exact neural basis of these effects is slowly coming to light and different imaging techniques have elucidated the neural basis of meditative practices. Will look more around.Ībstract Spiritual practices have been proposed to have many beneficial effects as far as mental health is concerned. But it seems finding info about this is not as simple. I just read that there is indeed a secondary system in the body which can measure the oxygen levels. That's why for certain treatments you go into a pressure chamber and get there pure oxygen to breath. But for this you need air with more oxygen in it or with a higher pressure. What you can do is by increasing the oxygen partial pressure in the air, to increase the blood plasma oxygen levels. As I read, you cannot increase the blood oxygen levels by breathing more or anything, as your red blood cells anyways are almost fully saturated on normal breathing. I'm actually quite interested in this, that's why I ask. AFAIR the body only recognizes CO2 levels and reacts on this (acidity of blood). You just start to get sleepy and get unconscious. Also interesting, someone else's experience:įight/flight response is triggered by low O2 levels What is the source for this? For as I understood it, you do not notice in any way if you have a lack of oxygen. Is there such thing as overdoing it when trying to access DMT? I feel like maybe I was pushing too hard by taking any more than 5 breaths as that seemed to be my clearest trip, and most true to a smoked-DMT experience. The feelings that follow are very intense and powerful but I struggle to remember what exactly was happening in my trip, as opposed to last night's 5-breath experiment. Then I experience a sort of skipping-record sensation and get pulled back into my body. Those experiences tend to end with me blacking out, having weird face twitches and eye movements, going into some sort of Dream that I can never quite remember. ![]() Usually I try DMT breaths at the end of a few WHM rounds, or at least 15 breaths. Warm and beautiful feelings, true to my past substance induced psychedelic experiences. Accompanied by immediate euphoria and a loss of any tension/discomfort regarding the fact that I wasn't breathing. ![]() Last night I started with 5 deep breaths and went straight into a breath-hold (on the in-breath), squeezed, and had visions of the "gears" I see during DMT trips. ![]()
