Third-eye 'good headache'?
During your mediation podcast you mentioned focusing on the so-called 'third eye'. Sometimes when doing so I get a sensation of pressure in the area, as if blood is slowly rushing to the front of the forehead. I think James Nestor in his book 'Breathe' called this a 'good headache', as it feels unpleasant but not painful. Do you know what causes this sensation? Or am I imagining it?!
P.O T.S Postural Orthostatic Tachycardia Syndrome
As P.O.T.S. is "caused" by a dysfunction of the autonomic nervous system, I noted that your discussions covering cold exposure and breathing techniques (in addition to other topics) spent some time digging into the mechanisms affecting aspects of the autonomic nervous system and how the system can be impacted by breathing, cold exposure, etc. Could you provide any insights and protocols that might help those suffering from P.O T.S?
