Wacky Ball is a stress ball, usually made from polyurethane foam rubber, that gives and bounces back as it is squeezed. Wacky Ball is a product that relieve your stress. The material provides just enough resistance as you squeeze it to work the muscles in the hands and wrists, without straining them too much. The tense feelings in the muscles only add to the mental effect that stress already has o
n a person. As you squeeze a stress ball, your hand muscles contract and relax. If you breathe deeply while squeezing one, you will begin to achieve something called progressive relaxation. This means that every time you squeeze and release the stress ball, you relieve a little more of the tension from all the muscles in your body. This happens progressively until you are at a more relaxed state. Squeezing the ball may also have additional helpful stress-relief effects such as giving your mind something else to focus on instead of whatever is causing the stress.
