Stress ball

Description

A turkey-shaped foam rubber stress reliever

A stress ball is a malleable toy, usually not more than 7 cm in diameter. It is squeezed in the hand and manipulated by the fingers, ostensibly to either help relieve stress and muscle tension or to exercise the muscles of the hand.

Despite the name, many stress balls are not spherical. Many stress toys are molded in amusing shapes and pad or transfer printed with corporate logos. They are presented to employees and clients as promotional gifts. Stress balls are the third most popular promotional gift in the UK. Repetitive stress injuries such as carpal tunnel syndrome are common. Because of the many shapes now available, stress balls are generically known as stress relievers.[1]

Types of stress ball

Different shapes of stress balls.

There are several different types of stress balls that originate from many different countries. The most common type of stress ball (in America) is the “bean bag” type (commonly known as a “Hacky Sack” in Australia). The stress ball that is most common in Australia is the foam type, this type prevents stress through resistance from squeezing the ball. The third type of stress ball is the Chinese form. These are not like the others as these are not squeezable, they are solid, they usually come in pairs so you can roll them together to make a soothing a sound and a smooth sensation feeling in your hands.[2]

There are many different types of stress balls. Some are made from closed-cell polyurethane foam rubber. This type of stress ball is made by injecting the liquid components of the foam into a mold. The resulting chemical reaction creates carbon dioxide bubbles as a byproduct, which in turn creates the foam.[3]

Stress balls, especially those used in physical therapy, can also contain gel of different densities inside a rubber or cloth skin. Another type uses a thin rubber membrane surrounding a fine powder. The latter type can be made at home by filling a balloon with baking soda. Some balls similar to a footbag are marketed and used as stress balls.
