I again did a sorta cold shower (in morning), 56 degrees, for 15 minutes in Seattle. I did breath holds of 40 seconds, 1 minute, 1 minute and 1 minute. Before shower, did 15 minute mediation with breath holds of 1.30, 1.50, 2.00 and 2.10. The breath holds are going well now. Getting visions and body very tingly. Also, did a 5 minute cold shower in evening (54 degrees at sister's house in Seattle) after 5 mile run.
