   Performed indoors.
   There was some shock when I turned the water cold, but not nearly as
   much as yesterday. I bathed a little while the water was cold, and I
   didn't get the second deeper chill I experienced yesterday.
   Yesterday was hard so I thought I'd slowly raise the minutes so that
   there wasn't a sudden change for my inner experiences to respond to.
   Today I kept the water cold for 65 seconds.
   After, I tried to do just a little of the breathing. I have experiences
   that act in response to things similar to meditation, so I took it slow
   like with the cold water, and stopped as soon as there seemed to be an
   issue. I just breathed 5 or 6 times, twice.
   I can hold my breathe out for a long time, so I stopped when there was
   something noticeable, like a change around my eyes. To keep it simple
   at the start.
   It feels different to fill with oxygen more than normal, even a little.
