After reading this article, I thought of gifting Dr. Wayne Hayes' ice vest to a friend. I googled Hayes and I found his website: http://coldshoulderweightloss.com.
I found his website shockingly bad. I wonder how anyone could buy a personal care product from a website that looks like that.
It's surprising how web presence can still be taken for granted. Especially when their website is a point of sale for their product.

Wait, a magical new weight-loss scheme based on some seemingly counterintuitive yet simple principal might be a scam? What a shock!
Why this junk is on the top of the HN front page I don't know.
I'm in Europe. I've been using only (cold) tap water in my house for more than a year. It began with a broken heater in the midst of last year's summer when I decided to postpone buying new one to see how long I can last with cold water. I thought that sooner or later I should catch cold and then I would switch back to using warm water. That summer was hot (up to 35 degree Celsius) and tap water was warm, slowly it began cooling but I didn't feel any difference. When it hit -25 degree outside I was sure that my cold water showers will put me in bed but that never happened. The only inconvenience was (and is) that many hygiene products (shampoos, soaps, and such) work poorly with cold water and it takes more time to properly wash myself. I can't say whether this habit affects my weight or gives any other benefit, but as long as it's not harmful I can't care less.
The article talks mostly about weight loss as a benefit. There are also suggestions that cold may improve your immune system. Wim Hof (aka the "Ice man") is exploring that idea[1]. Among other things, he runs marathons in the arctic on bare foot and sits in ice cubes for prolonged periods. He also did a ted talk a while ago. http://www.icemanwimhof.com/en-home
What's funny is that the article never suggests that the simplest solution would be to go swimming (Phelps example) instead of resorting to things like the cold vest or sleeping without a blanket.
And swimming has more advantages than just being cold : it provides your cardio in a non damaging way (contrary to running) and you gain a valuable skill that can save your life.
As someone who was a grad student in an apartment with poor heating: it's not worth it. Eat appropriately, and exercise. The bloody cold numbs your brain too. I also remember reading, though I can't find a good source now, that programmers perform better when warmer (until a point, maybe 27 degrees C). Besides, exercising feels good, while this feels bad. Might as well enjoy yourself.
There are quite a few studies that suggest the brain performs better when it's cooler.
TL;DR: One study suggests ability to recognize spelling and grammar mistakes improves in a cool room. A second study suggests ability to do math and make a correct decision based on it improves in the cool room. The third study suggests people in a warm room prefer to avoid complex cognitive decisions and rely on simpler patters of decision making even when it resulted in inferior choices.
YMMV. Empirically, I focus and perform better when a room is 18 - 19 C (below "room temperature", which seems to be 20 to 22 C). I am Canadian.
I don't think he'll sell many ice vests to women - they always seem to feel the cold. The women at work are always rugged up, while the guys (ok, all the guys do a lot of exercise) are mostly in shorts and t-shirts. In bed, my wife has a couple of duvets on, and I'm on the top of the bed with nothing on, sweating away. Maybe, based on the theories in this article, women would find it easier to lose weight if they let…
They're cold because they're more used to dressing up warm. If they let themselves be constantly cold, their metabolisms would eventually increase to heat them.
