Sensory deprivation tank therapy, commonly known as float therapy, involves floating in a tank or pod filled with salt water. Within the isolation tank, the water is saturated with enough salt to allow flotation without any effort, and is heated to match the individual’s body temperature, making it feel as if you are floating on nothing. These tanks are intended to minimize or cut out entirely outside stimuli such as light, temperature, and sound. Removing these distractions can be helpful for calming the mind, and in turn potentially relieving stress and anxiety. With studies showing that during float therapy, individuals become more aware of their breathing and heart rate, and in turn, more aware of their ability to control them. The relaxation this brings about can help reduce heart rate, blood pressure, and anxiety.
However, it should be advised that float therapy is not for everyone. There are potential risks for individuals with certain health conditions. People with epilepsy for instance should probably not try float therapy due to the danger if they were to have a seizure while in the deprivation tank. Also, those with low blood pressure or hypertension should consult with a healthcare provider before trying float therapy due the fact that it can decrease blood pressure.
