Related, but not the same. I’ve suffered from migraines since puberty. In my teens, I received biofeedback training and it turns out I was pretty good at it. Biofeedback is a relaxation technique; training involves hooking you up to a device that measures galvanic potential in your skin and converts it to an audio tone. Stress and relaxation have opposite effects on a number of measurable body phenomena including skin resistance, skin (extremity) temperature, heart rate, and others. I’ve practiced biofeedback regularly since and can rapidly lower my heart rate and increase my skin temperature at will. I wouldn’t depend on it to ward off frostbite but I usually don’t need gloves and my wife gets jealous that my hands and feet are almost always warm.
