I hope the lack of updates don't reflect a collapse in morale. I hit day 11 today. I literally glow red as soon as I step out. JD -- did a little research, and brown fat activation might explain it. Since researching that, I've been focused on standing directly under the shower with the water on my back and shoulders -- that's tough, but I try to hold it for close to a minute.
most of the literature says brown fat activation takes hours of exposure, and while cold baths are effective, a 5 minute cold shower likely will not be.
On another note, my boys have convinced me to take off Wednesday and go to the shore for a polar bear plunge -- they have off school, and we're aiming for a ski trip but the weather man is now forecasting poor ski conditions --55 and rainy -- so we have a new plan -- I hear the ocean temp is a balmy 33 degrees. So now I'm looking at my 48degree shower as "conditioning".
