In my experience after starting breathing exercises (not Wim Hof...more freediving oriented), it has the opposite effect to what you're positing.

Rather than just raising body temperature to become impervious to cold, it's actually giving your body a greater ability to regulate its own temperature. So in cold you're warmer, in hot you're cooler. When I started doing the exercises, I was living in Southeast Asia and sweating profusely whenever I left AC environments. After about a month of the breathing exercises, I stopped sweating almost entirely. I originally attributed it to my body adjusting to the climate, but when I returned home to the US, I also found that the cold no longer bothered me.

Do you have any such exercises I could do?

Some instructors have been mentioned elsewhere in this topic. Its considered inappropriate for an individual who has not been promoted to instructor rating to teach/assign breathing exercises because of the contraindications and complications that a student may not have been exposed to (since the student was being taught to do the exercises, not to teach them).
