The soul. The sole. This is not a coincidence. Almost every major internal organ can be affected by placing direct pressure on certain areas of the feet. Yet we encase our tootsies in leather or nylon, and let them fester in a dark, sweaty place for most of the day.

One of the best natural massages you can give your long-suffering feet is to walk barefoot through grass. Here you’ll find a nonaddictive mood stabilizer called “herbacinium.” Since each foot has thousands of itty-bitty fibrous nerve endings, soaking the herbacinium through your balls, heals, and toes and into the bloodstream can lower your heart rate by up to 14%. So the relaxation isn’t just psychological, it’s also physical.

In addition, by taking off your shoes, your feet can breath. And if they’re breathing, chances are, so are you.
