Hydrotherapy/ Magnesium float tanks

A Float Tank is a lightless, soundless tank filled with highly concentrated Epsom salt water heated to skin temperature. Floatation, also known as sensory deprivation, is simply the act of relaxing in a floatation tank; with all sights and sounds removed, and drifting into a meditative state that rejuvenates your mind and body. These float tanks are known to relieve stress, detoxify and reduce migrations.

Float Tank – The Science

Floating is achieved by adding a high concentration of Epsom salts to the water. Much like in the Dead Sea this raises the density and buoyancy of the water. Float tanks will use around 1000 litres of water and 550 kg of magnesium and sulphate-rich Epsom salts thereby increasing the specific gravity for the solution to around 1.27.
It is this change to the density that adds buoyancy to the water and allows a flotation tank user to float.

Float Tank using Epsom Salts

Epsom salts allow the float tank user to float but also do so much more. Ancient wisdom tells us that Epsom salts are an effective cure-all with benefits including stress relief along with easing aches and pains.

Epsom salts are rich in magnesium, which is the second most abundant element in the human body and one that is vital to good health and well-being. When floating, the Epsom salt solution helps with lymph drainage and promotes the absorption of magnesium.

Research shows that raising magnesium may have the following benefits:

Relieve stress – Excess adrenaline and stress are believed to drain magnesium, a natural stress reliever, from the body. Magnesium helps bind serotonin, the happy hormone!

Relaxation – Elevates chemicals in the brain that works to create a feeling of well-being and relaxation.

Migraines – Eases and prevents migraine headaches.

Detoxification – Flushes toxins and heavy metals from the cells in the body. This in turn helps ease muscle pain and clear out harmful substances picked up from our modern environment.

Diabetes – Improved insulin sensitivity aids blood glucose control which can aid in the prevention or severity of diabetes.

Heart Health – Improves heart and circulatory health. Preventing hardening of the arteries, and blood clots and lowering overall blood pressure.

Bone health – Magnesium helps assimilate calcium into the bones.

Better still, when using a float tank the magnesium is absorbed through the skin and the body optimises the levels of magnesium so there is no chance of magnesium levels become too high which can be dangerous.

In addition to improving magnesium levels, Epsom salt also provides sulphates, which are difficult to get from food but are easily absorbed through the skin. Sulphates play a role in the formation of brain tissue, joint proteins and the mucin proteins that line the walls of the digestive tract – all of which helps us live a long and healthy life, particularly as we age.

Epsom salts, whilst helping the user float, also provide a wide range of health benefits adding to the therapeutic nature of floatation therapy.

Sensory Deprivation

Sensory deprivation is the removal of stimuli from the senses. At the most basic level, a blindfold or earplugs are a form of sensory deprivation. In a float tank, sight and sounds are removed. The air and water are also heated to skin temperature so it becomes impossible to know where your skin ends and the water begins. And, of course, you are floating.

Floating in a tank creates the perfect conditions for removing all external stimuli. This is the sensory deprivation element. Your vision is restricted in the pitch black, you can hear nothing but your own body. You are completely buoyant in the Epsom salt water. This leads to a feeling of zero gravity with no real concept of up, down, time or space. The water and air are heated to body temperature so you are unsure where your body ends and the water begins.

Floatation Therapy

The science of sensory deprivation is known as Restricted Environmental Stimulation Therapy (REST). REST in a float tank has shown a transition from alpha or beta brainwaves to theta, which would ordinarily only occur before sleep and waking. In a flotation tank, theta brain waves occur whilst the user is fully conscious. For many users, this allows for great creativity and problem-solving.

There is also evidence of physical benefits including reduced blood pressure, cortisol (the stress hormone) and improvements to blood flow. REST is also used by many athletes who claim enhanced recovery and performance.


The environment in the float tank completely isolates the senses and blocks out all distractions including gravity, temperature, touch, sight and sound. This leaves you in a deeply relaxed and meditative dream-like state like the state you enter just before you go to sleep.

Your brain uses a lot of power to deal with the strain of gravity on the body, however, in an isolation tank, your body and mind is freed from gravity so can fully relax. As a result, the brain does not need to send out any commands to the body so activity in the logical side of the brain synchronises with the creative hemisphere.

This changes the brainwaves from alpha to frequency delta and theta waves, causing you to enter the meditative dream-like state whilst fully conscious.


Flotation can benefit everyone, from athletes and creatives to business people, the elderly, and those with medical issues. Floatation is a form of alternative medicine and boasts an extensive wealth of benefits:

  • Stimulates the release of endorphins
  • Creates calm and total relaxation
  • Rejuvenates the mind and body
  • Alleviates mental and physical stress
  • Helps with fatigue and jet lag
  • Improves sleep and insomnia
  • Improves creativity, healing, and visualisation
  • Expands awareness and heightens senses
  • Enhances mental clarity and deepens your mental state
  • Improves self-realisation and discovery
  • Helps with anxiety, depression, and motivation
  • Helps with phobias and addiction
  • Helps with PTSD symptoms
  • Decreases the perception of pain
  • Relieves bones, joints, muscles
  • Relieves aches, pains, and strains
  • Relieves arthritis, migraines, and rheumatism
  • Relieves fibromyalgia
  • Helps with pregnancy pain
  • Increases blood circulation and lowers blood pressure
  • Improves immunity
  • Helps athletes produce less cortisol, adrenaline, and lactic acid
  • Helps athletes visualise their performance for success
  • Helps athletes master the inner game and synchronise mind, body, and emotion
  • Reduces the risk of further injury and overtraining
  • Resets the body’s chemical & metabolic balance
