How float tanks work

The floatation tank contains a super-saturated Epsom-salt solution, which is about 25cm deep. This creates an environment similar to that of the Dead Sea, which lets you float effortlessly on the surface of the water and enjoy a feeling of weightlessness!

The float tank looks like a large, enclosed bathtub. They are usually built from fibreglass and are designed to block out all external distractions, such as sights, sounds, tactile sensations and gravity.

The salt-water solution is heated to skin temperature (35.5°C). Once you are settled, it is almost impossible to tell which parts of your body are in the water and which aren't. This will trick your brain into thinking that you're floating in mid air.

The buoyancy created by the Epsom-salt solution effectively removes the effects of gravity on the body. This will make you feel almost completely weightless, letting every single muscle in your body fully relax.

With ear plugs in and (if you choose) the tank's interior lights switched off, the quietness and darkness will allow your mind to drift into a deep state of relaxation.
