Renu Therapy Cold Plunge Review – Cold Plunging At Its Finest

Who is ready to plunge your body into ice-cold water for several minutes to reap the many health benefits of cold water immersion therapy? We see all of those hands raised, and we like it!

If you missed our article on the history of cold plunges, don’t stress. In this Renu Therapy cold plunge review, we’ll guide you through the physical health benefits of cold plunge tanks as we introduce you to Renu Therapy and all it has to offer. What are we waiting for? Let’s get right down to it.

Understanding Cold Plunges

A cold plunge immerses the body in ice-cold water for several minutes to elicit several health benefits. Cold plunges range from three to eight minutes, depending on the person and their tolerance to cold water. When just beginning, it’s recommended to start at only one minute and slowly increase with time to enable the body to adjust to the frigid temperatures.

Ice baths date back to 5,000BC when the Greeks and Romans used cold water immersion to relieve body aches and health issues. Nowadays, athletes use them after strenuous workouts to accelerate muscle recovery. Cold water restricts blood flow to aching muscles, decreasing inflammation, swelling, and pain in the area. At the same time, blood vessel constriction forces the heart to increase blood flow to vital organs more efficiently. Over time, this process increases blood flow through the body for better circulation.

The benefits of a cold plunge tub continue as the body temperature lowers and the digestive system kicks into gear to warm the body. That kick means more calories burned, and, in time, weight loss can result when paired with a healthy diet and exercise. Cold therapy also boosts the immune system by constricting muscles and moving lymphatic fluid throughout the body. Lymphatic fluid rids the body of harmful toxins and viruses. By encouraging the movement of this fluid, the body gets rid of toxins and feels better.

Cold plunge tanks have been linked to lowering depression and anxiety. Chemicals like dopamine and norepinephrine are ignited when the body is immersed in cold water. Dopamine increases pleasure, and norepinephrine boosts energy levels. Together, these chemicals can increase overall mood and lower anxiety levels for better health.

Renu Therapy

You may have heard of the Ice Barrel or other ice baths that people buy for home use so they can cold plunge whenever the mood strikes. While the Ice Barrel is less inexpensive, it requires water changes weekly due to no filtration system. It only provides sitting in an upright position rather than a reclining one.

Renu Therapy is a cold tub for cold plunge enthusiasts as it is a serious, commercial-grade product to increase overall health at home. While it’s an expensive option as the Cold Stoic, the standard cold plunge tub, costs $9,699.99, it’s a cold plunge with very little maintenance, consistent cold water without ice, and massive health benefits.

Cold Plunge Tub Features

First, the Renu Therapy cold plunge tank has a five-year warranty to ensure ultimate customer satisfaction with the product. The Cold Stoic ice bath exterior measures 64″ x 33″ x 34 1/4″, with the tank dimensions measuring 36″ x 24″ x 30″. It can fit larger individuals for both height and weight, which is lacking in competitors like The Cold Plunge tub.

A more significant version of the Cold Stoic is the Siberian Cold Plunge, which costs $13,399.99. The exterior is 80″ x 33 5/8″ x 37″ and the tank itself is 48″ x 24″ x 30″. While a more expensive option, this cold plunge tub is excellent for taller individuals or those with a heavier body mass.

Depending on your preference, both cold plunge tanks feature five different designs and wood colors, ranging from California redwood to Pacific cedar. The aesthetically pleasing design means it conforms to your space nicely without looking large, bulky, and out of place.

Filtration System

The Renu Therapy pledge is that the water is always clean. Renu therapy uses a four-part filtration system without harsh chemicals that damage the environment and your skin to make this happen. It uses active oxygen to oxidize the water and a dirt and oil removal buoy.

Silver ions are used via a sanitized mineral stick to ensure your ice baths are free from bacteria and algae growth. Due to this complex filtration system, the water rarely needs to be changed, saving you time, energy, and money.

Constant Cold Water

Rather than constantly buying bags of ice and hauling them to ice baths, the Renu Therapy cold plunge tank always maintains cold water, so there is no prep for your cold plunge. You can jump right in for results when you need better sleep and recovery scores. A thermostat allows you to maintain a temperature anywhere from 39 to 55 degrees Fahrenheit, so it stays cool. It’s a much easier way to keep water cold without buying ice constantly.

Simple Set-Up

Renu Therapy cold plunge tubs are easily set up and weather-proofed for outside plunges. No plumbing is required. An optional light is available for night plunges. Get relief from muscle soreness under the stars.

Final Musings on Renu Therapy

Are cold plunges worth it? We like to think so as the numerous health benefits speak for themselves. A reduction in inflammation throughout the body does wonders for aches and pains, and that’s what cold water immersion does. Increased blood flow for better circulation to vital organs and decreased anxiety are essential for overall health and well-being.

A Renu Therapy tub achieves those things more when cold plunges are incorporated daily or weekly into your lifestyle. If a simple thing like the TheraIce Hat can fend off migraines with cold therapy, maybe it’s time to include more cold treatments into your wellness routine. It’s something the whole family can enjoy, from growing children to parents, benefits are outstanding. This incredible product is waiting for you.
