Cold exposure toggles BAT, it’s why infants have a lot of it, they don’t possess the muscle mass to be able to shiver. Adults have very little BAT, and cold exposures activates it, as well as “Browns” some white adipose fat.
I hated cold showers my whole life, but no-one said you have to go right from ahot shower to freezing cold. The first three try at trying to step under a very cold shower head didn’t even last a second, so it was pretty evident that wasn’t going to work.
I ended up taking my normal hot morning shower, and at the end, turned it down so it was cool@62, and stood there for a couple of minutes. I kept slowly progressing over a couple of weeks, till I was able to acheive @42 degrees. The most surprising thing is it actually felt good, if I had kept trying to just do it like I initially did, about three years ago, I’d still be trying LOL.
BAT is how babies stay warm, they don’t have muscles yet to shiver, We have very little left as we reach adulthood, and cold exposure does activate what we do have, and can “brown” some of our SubQ fat to a degree. The SubQ and what little BAT we have on our bodies is very healthy for us, the other three types of fat are very detrimental to our health.
I had a Blk on Blk with a pretty extensive carbon pkg on my Turbo, drove it for five years, sold it to one of my BILs and he promptly totaled it.Just been rocking a 4C Spyder the last few years, it’s a hoot.
