I measure CP daily, mostly in the morning, and also practice Buteyko breathing. Until now, my CP had remained at 45–55 sec.
Today, my CP was 1 min 27 sec. In fact, I released my nose out of surprise when I looked at the stopwatch. I somehow lost track of time during the CP, relaxed, and the pause was maintained completely effortlessly. I think the increase may be due to my having started practicing Wim Hof's Intensive breathing course. But such a sharp jump in CP is also possible before the sanogenesis process. I'll observe it.
