No, my 50F river bath *was* painful & cold at first, and now is not.
Hey, I just remembered another "benefit." You can decide ... GUYS STOP READING HERE. TMI. DON'T SAY YOU WEREN'T WARNED.
AF all my life came at any time of day, but never at night, and came light for a few days, then more and more, then tapered off a few days.
Since starting CT in February - the only change I made at the time, after being primal for two years, etc., etc., - that very month, AF started coming while I slept, and strong (but never super super heavy like it would be by day 4 & 5 before ... and interestingly, there's a lot when I choose to wipe, but very little external flow until that moment), then gone after 2 or 3 days, just shut off like a tap.
Each of the four months since then were exactly like this.
I've read that it's supposed to be like this from women in traditional societies. It's so much easier, very predictable, and I could totally see how women managed something like this for the couple dozen times they would have had AF in their lives.
I can't wait to re-test my hormones. Many women have seen lighter PMS, lighter cramps, lighter flow. I never had PMS, never had cramps, so I wonder if I'm just closer on the scale to "ideal" and so I'm seeing the ideal AF as my first big hormonal change. (Never had too much estrogen, just too little of most things and too high an E:P ratio.)
