What Is Specific Gravity And Why Having The Correct Specific Gravity In A Float Tank Is So Important

Specific gravity refers to the density of a substance, and in the case of a float tank, it refers to the density of the water and the dissolved Epsom salt. The water in a float tank is typically saturated with Epsom salt, which increases the specific gravity and allows the user to float more easily.

The specific gravity of the water in a floatation tank is an important factor in achieving the sensation of weightlessness. The specific gravity is a measure of the density of a liquid, and it is typically expressed as a ratio of the density of the liquid to the density of pure water. The higher the specific gravity, the more dense the water. In a floatation tank, the specific gravity is usually around 1.3, which is much higher than the specific gravity of pure water, which is 1.0.

Having the right specific gravity is crucial for several reasons. First, it ensures that the user can float effortlessly, without having to exert any effort to stay afloat. This allows for a deeper level of relaxation, and a far superior user experience, as the body can fully relax and release tension.

A high specific gravity also helps to create an environment that is free from external stimuli, such as sound and light. This is important for sensory deprivation, as it allows the user to focus on their inner thoughts and feelings without distractions.

Floating in water with a higher specific gravity will create a feeling of weightlessness, which can be beneficial for people with chronic pain or injuries. The buoyancy of the water supports the body and takes pressure off joints, allowing for a more comfortable and pain-free experience.
