The use of heated water as a health and relaxation aid is not a new concept. Cultures have used hot springs( bodies of water heated by geothermal forces) as bathing and gathering spots for millennia.
Today, these man-made hot tubs and spas are created with inspiration from these natural springs.
Ancient cultures were known to make use of natural hot springs, from Japanese “onsen” since at least 737 A.D. to the Roman thermal springs and bathhouses.
When hot springs were not available, past cultures developed rudimentary hot tubs by adding heated stones to a cauldron of water.
The practice of bathing was so engrained that the Roman legions, during their long occupations in foreign lands, built their own baths at mineral and thermal springs in the newly conquered lands. Examples are found all over Europe.
In the 1940s hot tubs began to appear in the US, inspired by the Japanese ofuro. Hydrotherapy pumps were introduced by Jacuzzi. Fiberglass shell hot tubs appeared around 1970 and were soon superseded by cast acrylic shells.
What Really is a Hot Tub and How Does It Work?
A hot tub is normally used to refer to an above-ground spa. A hot tub or a spa is a completely self-contained vessel, and the hot water and jets provide a pleasurable soaking experience for the users.
A hot tub is a large tub full of water that is used for hydrotherapy, relaxation or pleasure. A hot tub is designed to be used by more than one person at a time, with many models accomodating four or more people.
Generally, hot tubs are located outdoors, although they can also be installed indoors if you desire.
While there are different brands and models of hot tubs in the market today, their essential operation remains the same. They have pretty much the same mechanical construction that allows water containment and the basic operations such as heating is the same.
How Does a Hot Tub Work?
Before we get into how a hot tub really works, let’s familiarize ourselves with the different parts of a hot tub that makes it work properly.
Parts of a Hot Tube
Below are the various components of a hot tub and their functions. Once we get the parts and their functions right, basically, we would have understood how a hot tub works.
The shell contains the water, has various seats in its mold, and provides mounting points for the jets. It is the inner hot tub surface that is typically made of acrylic or another weather and chemical-resistant thermoplastic.
The shell can withhold the weight of the water, bathers, and other equipment without breaking because it’s always reinforced or supported with fiberglass backing or high-density polyurethane foam, or some combination of the two.
This part plays two roles. Firstly, it provides structural support for the shell and equipment and lastly, it also hides the less appealing equipment like the pumps, plumbing, and heaters behind stylish doors. Older hot tubs used to have wooden cabinets, but today, cabinets are made from weather-resistant polymer and are extremely easy to maintain.
Jets or Hydro Jets
The pumps are responsible for circulating the water in and out of the hot tub, filtering and operating the jets.
The pump has two speeds: the low speed for filtering mostly heating and the high speed for operating the jets. The speed operation is controlled by the spa pack based on the thermostat and time clock, if one is present.
The high-speed operation is controlled by a spa pack air button, which allows for high-pressure steams in the jets.
Some older hot tubs may use special air blowers to create additional bubbles in the water. These can be used instead of or in addition to the typical air jets, although their use dramatically increases electrical consumption, and hence cost of ownership.
Topside or Spa Side Control
Equipment Area or Access Door
This may differ slightly between different hot tub models. The manual will generally indicate where this area is to have an idea of where the plumbing and parts are located.
With the basic parts of the hot tube explained above, I am sure you have a pretty good idea of how a hot tub works.
Benefits of Using a Hot Tub
Stress is a result of muscle tension, headaches, fatigue, and soreness. Taking a regular hot tub regularly can relieve you of tension and stress.
The buoyancy eases pressure in joints and muscles, while heat increases blood flow to muscles and promote rapid healing.
Furthermore, hot tub jets provide therapeutic massage, stimulating the release of endorphins, which are the body’s natural painkiller.
Relief from Symptoms of Arthritis and Rheumatoid Arthritis
Arthritis is a common yet painful sickness that is characterized by joint pain, swelling, accompanied by a decreased range of motion.
Rheumatoid arthritis, an autoimmune disorder that can cause widespread pain throughout the body, occurs when a person’s own immune system mistakenly attacks their joints, resulting in swelling and stiffness.
These conditions can cause chronic pain and reduce the quality of life.
According to research, the simple relaxation gained from a soak in the hot tub may be enough to help you drift into a more peaceful sleep.
Two different studies performed by a studTrusted Source have proven to improve sleep in people with insomnia and fibromyalgia.
The first was done by using passive body heating as a treatment for insomnia in older adults. Though the study was small and subjective, it was found that hot baths promoted significant deeper and more restful sleep.
The second was performed in 2012 to look at the effects of hydrotherapy on physical function and sleep quality for people with fibromyalgia.
It was done on a small number of females between the ages of 30 and 65. That research concluded that hydrotherapy helped improve sleep quality along with other symptoms of fibromyalgia.
Lower Blood Pressure
A study has shown that relaxing in a hot tub can be beneficial for heart disease patients. The study showed that relaxing in a hot tub was less stressful on the heart.
It also confirmed that soaking in the hot tub for as little as 15 minutes will lower blood pressure.
Improved Insulin Sensitivity
Promotes Weight Loss
In clinical studies patients who used hot tubs lost an average of 3.5 pounds in weight without any new diet or physical exercise programs.
In short, the weight loss resulted from the hot water massage simulating the effects of exercise, on the muscles.
What is the Difference Between a Hot Tub and a Jacuzzi?
As already established above on what a hot tub is, a Jacuzzi simply is a trademarked brand of ho tubs, bath products, and pool equipment. So basically, just as some refer to every brand of toothpaste as Pepsodent, the same way people refer to any hot tub or spa as Jacuzzi.
Jacuzzi’s company history can be traced back to the mid-20th century when the Jacuzzi brothers invented an underwater pump that could be used to relieve pain in arthritis patients.
They soon created a tub with a built-in jet whirlpool, which took off in popularity. In just a few years’ time, Jacuzzi became a household name and was quickly used to refer to any and all hot tubs, however incorrectly.
