Luckily in those moments when we're feeling at wit's end, we always have stress balls to squeeze!

What Are Stress Balls?

Stress balls are flexible, squishy toys that are used to relieve anxiety, help with meditation, and ease any muscle tension in the hands and wrists. People also like to use these toys to improve concentration at school and work.

Stress balls are fun tchotchkes for your desk or shelf, but you're probably wondering if they actually work Good news! A variety of studies have found that squeezing a stress ball can help with focus, dexterity, blood pressure, arthritis, sleep, and of course, stress.

When Were Stress Balls Invented?

Early stress relievers were invented hundreds of years ago in ancient China. Warriors in the Han Dynasty, one of the largest and most powerful empires in history, squeezed walnuts during moments of high anxiety in battle.

After the Hans fell at the Battle of Red Cliffs, the Song Dynasty took over in 960 AD. This influential empire still used fidget objects to increase focus and anxiety in battle, only replacing the walnuts with smooth stones or iron balls.

Perhaps the most influential ancestor of the modern stress toy, however, were Baoding Balls. These balls were made from iron, jade, or solid stone and were mass produced in Baoding, China. Rather than squeezing, they would be rolled around in the hands, creating a soothing feeling and sound. Each ball was decorated with a custom design that was meant to encourage relaxation, harmony, health, and positive vibes.

Walnuts, stones, and Baoding Balls showed the value in fidget objects. They would be a big inspiration when it came to the stress balls of the future.

When Was Polyurethane Invented?

Dr. Otto Bayer of the DuPont Corporation created polyurethane as a substitute for natural rubber in 1937. This flexible material was a big deal during World War II as it was used to make uniforms that were resistant to mustard gas as well as sealants that protected metal weaponry and machines from corrosion.

Polyurethane took on a life of its own following the war. It was used in everything from insulation and packaging to bedding and furniture. By the 1980's, the squishy material was also found in the first commercial stress relievers.

Did you know?

Hans Selye adopted the term "stress" as a psychological concept in 1936, around the same time polyurethane was invented. Before then, people didn't really have a word for their anxious feelings..

When Was Polyurethane Used for Toys?

Polyurethane was first used to make toys in 1969. Reyn Guyer, the guy who invented Twister, used the material to create squishy sports balls. He took this idea to Milton Bradley who then passed it on to the Parker Brothers.

An entire company was built around these novelty foam sports toys. It was called "Nerf," and people couldn't get enough of this new brand. In fact, 4 million Nerf polyurethane footballs alone sold in the 1970's. The success inspired the Parker Brothers to create even more products including foam basketballs, baseballs, and even high-flying rockets!

Nerf proved that everyday people would buy polyurethane toys. Without the brand paving this road, stress balls may have never found an audience!

Who Invented Stress Balls?

One day at work, a TV writer in California named Alex Carswell got so frustrated that he whipped a magic marker across the room and broke a picture of his mom and dog. It was in this moment that he was inspired to invent the first commercial stress balls. They were advertised and sold in retail stores by 1988.

Carswell's Stressball" was made of polyurethane and contained a microchip that activated the sound of glass shattering when it was thrown. Dakin Inc. (who eventually merged into Applause Toys) showcased these new stress balls at the International Toy Fair in New York.

The Story Behind the First Stress Ball

The first stress ball created by Alex Carswell wasn't an immediate success. This can be blamed on all of the following:

Icon expensive

Expensive Price

The Stressball was sold at $24.95 each, which is a far cry from the stress toys today that can be purchased for under $1.

icon poor reviews

Poor Reviews

Sports Illustrated called the Stressball "nothing more than a lowly descendant of fast food containers and baseballs."

icon bad marketing

Bad Marketing

Many people felt overworked, but the Stressball was advertised specifically to down-on-their-luck stockbrokers. This made it seem like only yuppies who were dealing with the pressure of losing fortunes would want one of these toys.

icon microchip speaker

Used a Microchip and Speaker

A ton of Stressballs were thrown out when they no longer made the sound of breaking glass. This is because it was impossible to replace the microchip and speaker.

icon not squishy

Not Squishy

Even though the Stressball was made from polyurethane, it wasn't as soft as the stress toys we squeeze today.

Still, it wasn't all bad news when it came to the Stressball. NFL wide receiver Michael Irvin used one when he was feeling nervous about a game. Meanwhile, the National Exercise for Life Institute placed the Stressball on their top ten healthy gift guide list in 1988.

Regardless of the mixed feelings, we wouldn't have so many amazing stress balls without Alex Carswell's prototype. We don't even need the sound of breaking glass to feel that much-needed relief!

When Did Shaped Stress Balls Come Out?

Stress balls were simple round balls in the 80's, but that all changed thanks to two promotional products suppliers: 1) Ariel Premium Supply, and 2) ALPI International. These companies created stress balls that were shaped as animals, people, cars, trees, flowers, boats, food, and anything else you can possibly imagine!

Are There Any Stress Ball Lawsuits?

Unfortunately, stress balls have been the subject of many lawsuits over the years. One such case came in Ridgefield, Washington. The town's mayor accidentally hit a resident in the head during an event. This resident filed a claim seeking $500,000 in damages. The defendant had to have six surgeries to correct the damage done to her left eye.

This isn't the only time stress balls were misused in the workplace. Jackson National Life Insurance paid over $20 million in a U.S. Equal Employment Opportunity Commission lawsuit. The company was blamed for purposefully throwing stress balls at employees.

The key takeaway here is to not cause harm with your stress balls! After all, they're meant to provide relief, reduce anxiety, and put you in a good mood.
