Hi,
Have you ever herd this exercise for cold feet and hands. I believe it is a Russian doctors theory.
Could be a little doggy,what do think.
"Breathing exercise to warm up cold hands and feet
Sit down at a table with your spine straight. Relax all your body muscles. Next, instead of taking your usual inhalation, take a slightly smaller inhalation (about 10% less) and then immediately relax all body muscles, especially the upper chest and other breathing muscles. Take another (smaller) inhale and again completely relax.
With each breath, continue to take a small or reduced inhalation and then completely relax. You will soon experience light but comfortable air hunger. Your goal is to maintain this light air hunger for 2-3 minutes. For faster results, if you do not suffer from heart disease, hypertension, migraine, and panic attacks, you can make air hunger stronger and stronger. Your breathing (it is called reduced breathing) can be frequent during this exercise but this is normal. If you do this exercise correctly (you indeed breathe less), your hands and feet will be warm in less than 3 minutes. (For patients with advanced Raynaud disease, it may take longer time, up to 1-2 weeks, and more breath work, so that to improve circulation and body oxygenation, in order to normalize their automatic breathing pattern and cure the condition.)"
