What Sensory Deprivation Is, Isolation Tanks, Hallucination Claims…


it is fairly easy to deprive yourself of sight or hearing;

simply close your eyes or plug your ears. It’s more difficult to deprive yourself of the other senses. A sensory deprivation chamber works by eliminating outside stimuli. The chamber is typically dark, sound-proof, scent-less, and with a temperature close to the temperature of a normal human being’s skin.

The only noises would be ones you would have to create yourself. There is a sense of almost zero gravity as you float. The removal of outside stimuli allows the person to focus solely on the present moment and can be very useful for meditation. However, other research supports the idea that even removal of one of your senses for an extended period of time can lead to hallucinations. Even fifteen minutes of almost-total sensory deprivation was enough to lead some participants to have temporary hallucinatory visions such as seeing faces or shapes that were not actually there, a heightened sense of smell, or sensing a presence. Most of the research shows, however, that the overwhelming majority of people actually find it relaxing and want to experience it again and again.

Scientific studies have confirmed that there are numerous advantages to controlled short-term sensory deprivation through isolation chambers.  These chambers (or isolation tanks) have been shown useful in treating chronic musculoskeletal pain, hypertension, and motion disorders (such as vertigo and headaches).  Some studies have also shown that it can help with insomnia and stress related problems.  Many people who have tried these floating tanks have also reported being in almost a zen-type and stress-free state immediately after an hour long session.
