It's called cold thermogensis [1]. Fat burning could be one benefit, but apparently it can help your body get more adapted to changes in temperature. Some people who do cold plunges or cold showers feel that they can handle temperature fluctuations better, although most of that evidence is anecdotal. I personally switch to a cold shower after a hot shower and it makes me feel amazing afterwards. People have experimented with hot and cold temperature variations for years, like the Finnish with their saunas, and native Americans with sweat lodges.
