Stress balls are proven to improve blood pressure, anxiety, arthritis, and concentration. They also build hand strength, create a healthier heart, and improve sleep.
People don't live in environments that are always relaxing, there are things sometimes irritate you --noise, an important exam, a job interview, a strange crowd, if you have a stress ball in hand, this terrible environment may be less threatening to you, because no matter how chaotic the outside world is, your hand touches a soft, tightly fitting sphere, and the elastic touch created by the hand squeezing will make you feel safe and relaxed.
