The post 10 Amazing Facts About Hot Tubs first appeared on Swim University.

You’re spending the final hour of waning sun light in the snow-covered mountains. You’re looking south with your position surrounded by sharp mountain ridges jutting from the earth. Looking straight up, the sky is emblazoned with the deepest blue the earth can possibly conceive. As you transition your vision downward 90° you witness the earth’s atmosphere dispersing the light from the sun into shades of purple, red and orange.

The scenario is calming, erasing any fears or regrets from the day. You close your eyes to wash your vision. You open your eyes again as you hear a wolf cry in the distance and notice the last sliver of sun fall behind the mammoth rocks.

Once again, your eyes are closed. The babbling of the churning water becomes evident as you focus on the deep warmth that massages the stress from your tired-grown muscles. The water’s current moves around your body, collecting your tension as it heads off to pass. Without the hot tub, this scenario wouldn’t be complete. Without the hot tub, your euphoria would not be possible.

This hot tub is amazing.

Hot tubs, or at least the equivalency of, have a long recorded history of enjoyment by human (and other) civilization for hundreds of centuries. Now that we are all in the right state of mind, let’s take a look at 10 amazing facts about hot tubs to think about the next time you take a soak.

1. Hot Tub “Jets” Came From Early Aircraft Machinists, The Jacuzzi Brothers


(The Jacuzzi Brothers)

Jacuzzi isn’t a name conceived by some genius advertising company; it’s the last name of seven brothers that immigrated to the United States from Italy at the turn of the 20th century. Transplanted on the West Coast in Berkeley, California, the Jacuzzi brothers forged their way into the aircraft manufacturing business, machining pumps and propellers as well as the first ever enclosed monoplane that was utilized by the U.S. Postal Service.


Transitioning their expertise with hydraulic aircraft pumps to agricultural use, the brothers were laying the groundwork that would eventually support a much more personal matter. In 1948, one brother devised a bathtub pump for his son who was ailing from chronic pain caused by rheumatoid arthritis. The pump was installed in the tub at home to provide daily whirlpool treatments to treat the young boy.

Over the next 25 years, the development of the Jacuzzi name we are all familiar with made its way to the public eye. By the 1970s, the spa industry was taking off with the Jacuzzi brothers leading the way.

Diatomaceous Earth (DE) spa filters consist of a filter element that is millions of years old. The material comes from fossilized Diatoms that are found in oceans, fresh water, soils, and on damp surfaces. The hard-shelled algae are crushed to form a fine white powdery substance that is effective at trapping particles in water.

Although we might think of health tourism as traveling abroad for an operation, by the 17th century English families traveled from far and wide to soak at Bath, England. Bath’s hot springs were first discovered by the Romans around A.D. 50, with a temple dedicating the area to the god and goddess of healing. Throughout the Middle Ages, people traveled to Bath for the soothing springs in hopes of curing their ailments. Growing popular in the 17th century, this trend continues in present day.
