I personally have more than 10 years experience on sitting in the cold all day long, with only summer clothes on. Like 0 to 5 Celsius, with only shorts on, not even socks. I am winter swimmer as well. I do that, because i can think a lot more clear in a cold environment, it is good for the brain. Granted in Greece there is not that much cold, maybe 1 or 2 months of 0-5 Celsius. That can be achieved by putting music on, which speeds up the heart pulse. Usually hard rock, metal, thrash metal etc. In that case, the body starts sweating a lot, not matter the temperature. I combine that, with 5 simple exercises i do all day long which are important as well. My point is that using music, someone can be in charge of his heart pulse. But my biggest complaint always was that these metal guys, are masters of the guitar, but other kinds of music have better taste in rhythm, in melody etc. Using programs like that we can evolve it a little bit, to be more pleasurable to listen. I know about about binaural beats, i have tried to listen to different hertz for hours on end, they don't work in my opinion. At least in my case.
