Day 18 Whole30 cold swimming
Sunday, November 11, 2012
The pool has really cooled off. 69 today. Outside temp 59, so it is headed down some more. We still have solar heat on, but not using the electric heat. Pool not covered, hubby complaining.
He said he wanted to sell the marvelous house he built me here and move back to MI. So, I have been doing MI training.
Door open, fan on at night with a sheet or less and swimming in the colder pool.
The notion of calories in and calories out is true of course, but did you notice that your body works to keep its internal temperature steady? Sweat when hot for evaporative cooling and shiver when cold for heat?
Well, you can play it to your advantage to cool the body when safe and possible. So I swim in a cool pool and my body uses calories to retain the core temperature.
I have been swimming each day as the pool cools, so it has been rather gradual.
I have also sat with an ice pack on the back of my neck and upper back where adults still have some brown fat. The brown fat works to make heat. I stimulate it to work.
It is all called cold thermogenesis. Look it up.
DO NOT TRY THIS AT HOME OR WITHOUT CONSULTING A PROFESSIONAL.
