Sensory deprivation effects

The water in a sensory deprivation tank is heated to skin temperature and nearly saturated with Epsom salt (magnesium sulfate), providing buoyancy so you float more easily.

You enter the tank nude and are cut off from all outside stimulation, including sound, sight, and gravity when the tank’s lid or door is closed. As you float weightless in the silence and darkness, the brain is supposed to enter into a deeply relaxed state.

A 2015 study divided 46 people into two groups based on how prone they were to hallucinations. Researchers found that sensory deprivation induced similar experiences in both the high- and low-prone groups, and it increased the frequency of hallucinations in those in the high-prone group.

• Float for an hour.
• Music plays for the last five minutes of your session.
