What is Floating?

Learn about Floating and it's Benefits

Float on the surface of a warm, buoyant solution in a sensory-deprived environment with soothing music softly playing in the background, lights slowly fading from light to dark, in what feels like an infinite space, with nothing but your mind at rest and body at ease.

Floatation Basics

Floatation Therapy

Floating involves laying in a concentrated Epsom salt solution, heated up to the same temperature as the human body.

  • Float weightlessly on a solution of Epsom Salt and water.
  • Relax in a sensory deprived environment, peacefully disconnecting you from the world.
  • Invigorate your body, with all the benefits of lying in Epsom Salt.

Common Floatation Tank Names

While the history of floatation goes back many decades, there is not an internationally recognised name. This can be attributed to the large number of floatation tank styles, but generally speaking, most refer to the equipment that is required to run floatation therapy.

  • Sensory Deprivation Tank
  • Isolation Tank
  • Float Pod
  • Float Cabin
  • Float Room
  • Salt Pod
  • Relaxation Tank

One key difference with some common names is reference to tanks/pods and rooms. Float rooms are generally rooms built specifically to run floatation, lowering their versatility and adaptability for future changes. Pods/tanks, like the Exo, largely avoid this issue.

Profitability of Float Tanks

One of the key concerns about offering floatation therapy in your business is how profitable it is. While there is no fixed answer to this due to the amount of variables, it is explored in depth on our Financial Returns page. Generally a float tank will generate a steady stream of profits. 

  • Easy to use, minimal training.
  • A single member of staff can manage multiple Pods.
  • Compliments many other Wellness Therapies.

Floatation Therapy, In Depth

What Does Floating Feel Like?

Floating is a unique and calming experience. When you enter the tank, you find yourself in a weightless state as the high concentration of Epsom salt in the water allows your body to float effortlessly. With no external stimuli to distract you, you may find yourself in a state of deep relaxation with reduced muscle tension and a sense of calmness.

As you adjust to the darkness and quietness of the tank, you may find yourself more aware of your breath and body sensations, allowing you to focus more deeply on mindfulness and meditation. Many people report a reduction in feelings of stress and anxiety after floating, as well as relief from chronic pain and improved sleep quality.

Additionally, some people find that the sensory deprivation experience helps to stimulate their creative thinking and problem-solving abilities, leading to a greater sense of mental clarity and focus. Overall, floating in a floatation tank can be a rejuvenating and beneficial form of self-care that allows you to disconnect from the stresses of daily life and achieve a greater sense of physical and mental well-being.

The Science Behind Floatation Therapy

The scientific term for the practice of Sensory Deprivation (i.e. Floating) is Floatation-REST, which stands for Reduced Environmental Stimulation Therapy. The float experience minimizes sensory input from various channels, including sight, sound, smell, taste, thermal, tactile, gravitational, vestibular, and proprioception. By reducing these stimuli, individuals may experience benefits such as reduced anxiety and depression, lower stress levels, increased happiness and feelings of calmness and tranquillity.

What Makes You Float In A Float Tank

Float tanks achieve a state near to zero gravity by adding high concentrations of Epsom salt into the water. By using the correct amount of salt, the buoyancy increases, allowing a person to float. This mimics the environment in the Dead Sea, a popular location for people looking to experience weightlessness. Specifically, an Exo Float Tank uses 550kg of Epsom Salt with 850 litres of water to achieve floatation.

Why Use Epsom Salt?

Of the possible substances that could make a person float, Epsom Salt stands out as the most beneficial for its users. Alongside its ability to increase the buoyancy of the water, Epsom Salt contains high concentrations of magnesium, a mineral vital to the function of the human body. During a float, magnesium is absorbed through the skin. As this happens, the body optimises the levels of magnesium, preventing levels from becoming too concentrated.

Magnesium is a mineral linked to the Cardiovascular and Skeletal Systems. It has been shown to assist in keeping blood pressure at a regular level and strengthening bones. It also supports the development of muscles, nerve functions and energy productions.

Due to a combination of dietary and lifestyle choices, many people have lower levels of magnesium. Floating offers an alternative source of magnesium.

The Exo Floating Experience

The Exo Float Tank is very different from any other floatation tank on the market. Upon entering the room, you will notice the first difference. The tank remains empty, ensuring your salt solution is fully cleansed and filtered. The tank readies while you shower, showing its crystal-clear waters filling up its brilliant white shell.

The environment in the Exo floatation tank completely isolates the senses, blocking out all distractions and creates a sensation close to zero gravity. Being in an environment like this allows you to deeply relax likened to a meditative dream-like state.
