After losing blood flow to three of my fingers for about 20 minutes yesterday, I decided to do some research on Raynaud's syndrome to see if there was anything I could do to help prevent the symptoms. It was actually quite interesting. I already knew it had to do with poor circulation, but I was unaware it was related to overstimulated blood vessels; basically, being exposed to cold or stress causes them to constantly constrict, causing the blood to drain from those areas. Naturally then, habits like smoking or caffeine dependencies (here's where it hurts...) aggravate these conditions. So kicking that coffee habit might not be such a bad idea after all.
