Icy Feet, Icy Reception?
Story Updated: Aug 13, 2012
..cuddle up...and find that your feet are always ice cold?
While it sounds pretty basic, new research says it's because of an incredibly complicated biological mechanism.
Through some high tech experiments, researchers at Nationwide Children's Hospital in Ohio discovered an interaction going on between a series of molecules and receptors on muscle cells in the lining of the skin's tiniest blood vessels.
Under chilly conditions, the process shuts off blood flow to conserve heat for your internal organs.... a unique and physiologically important response.
The findings may provide clues for disorders like Raynaud's disease - a condition where people lose circulation in the fingers, toes, and occasionally other areas when the body overreacts to cold temperatures.
While the research offers an intriguing reason why cold feet happen, it doesn't offer a solution on how to fix the problem...so you may still need to grab an extra pair of socks!
