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.
Read bunches.

    More power to ya! I don't like cold! I can't stand my pool below 78! It may work wonders on that fat, but I'll let you others take care of it and I'll just do my regular exercise thing! Have fun, but be careful. I read once that you can have a heart attack by jumping into water below 72 degrees! I suppose it is healthier by you gradually getting used to it. But, again, more power to ya!

    Northern lakes seldom get warm and I have always enjoyed the cold swim of late spring through mid fall. Now being in Florida the ground temps warm the water and it stays around that 65-70 degrees. The showers are wonderful and very energizing. But there is something to be said for that warm tub of comfort too :-)

Thanks for the great share!

    Our pool is down to about 70 degrees and I cannot swim in it no matter how good it would be for me -- I salute your capacity for punishment! I'm waiting for a pool heater to be installed in the next few weeks so we can bring the pool back to 85.

    Fascinating about the thermogenesis. I will look it up and find out more.

    Haha. I remember it being 100o out and swimming in a 70 something pool, and getting out and feeling cold. It's relative I suppose. I read somewhere that the small blood vessels that warm the skin sink further into the body when it's extremely warm weather for long periods of time. That the reason we aren't acclimated to colder area for a year is because these blood vessels take a while to return to the skin to warm it. Don't know if true, but certainly interesting.

    I read about the ice method in The Four Hour Body - and then watched the author climb into an ice water bath on Dr. Oz. Brrrr! emoticon

    I need to do the neck thing, at least. No access to a cool pool. I don't seem to like being either very hot or very cold...

    It does take some getting use to, but it does work and has it's benefits. It also helps us to build our BAT which they think we lose from when we are kids, about the age of 8 or 9 I think. That's why kids can tolerate colder water than we can :)

Anyways, kudos to you! The shivering is a great workout!!

Thanks for sharing!

    Good luck... I used to swim outside in December but I think I'm over that... unless it really works for you!

    Yes, I remember my anatomy/physiology professor telling us that the most reliable way to ramp up your metabolism was to sleep with the windows open so you could be colder at night!

    There's no way I could swim in a cold pool. .... no matter how many calories it burns. ...... I guess I'm just to cold natured.
