I used to run on the warm side all my life, then got to where I felt chilly a lot, did not sweat hardly in hot weather, felt sluggish.
I have been taking Lugol's iodine (2%, 5 drops a day) for many moons, cooking with coconut oil, avoiding bread with brominated flour, mostly avoiding fluoridated water, never use fluoride toothpaste...still was not consistently warm by any means.
Recently I got a nasty and persistent lung congestion that was going around, which gave several people I know pneumonia. I said to myself, "That ain't gonna happen to me! " I thought about that old "Back to Eden" book, and how the old herbalists talked like cayenne would practically raise the dead!
Seeing as its been years since I ate habaneros every day, or even that many jalapenos, I went at it cautiously. Every day I would heat up about 4 ounces of water, add a mere 1/8th teaspoon measure of cayenne powder, and drink it.
I did this for maybe a week. Been comfortably warm ever since, including through a recent cold spell. I think all the other things I've been doing played a part, but I believe cayenne was the real "magic bullet".
Everyone is different, your mileage may vary! Some people get along well with hot peppers, others may not.
