Did you know that your hands and feet can carry a lot of stress? I was totally unaware of this fact until recently. And was given this cheap tip for relieving it. This also helps if you get cramps in your feet. Take a tennis ball and roll it around on your hand, or feet. My Mr who is prone to foot cramps has a couple of tennis balls at his office and while he works he will use on his feet. It has really helped reduce the cramping. Honestly it just feels good too. So there is a little stress relief tip!
