Anxiety is a widespread problem with the side effects dampening our day to day life and work performance. sensory deprivation is really a bad name for the float experience, according to Justin Feinstein, a clinical neuropsychologist who studies the effects of the practice in his laboratory at the Laureate Institute for Brain Research. The pools reduce external stimulation, and thus enhance the internal sensation of a person’s world, he explains.
Preliminary brain imaging data also implies flotation has the same effect on the brain as some anti-anxiety drugs, says Feinstein. In his research, he compared brain imaging of people given the anti-anxiety drug Ativan to people who had floated and found the same dampening of the amygdala, the part of the brain responsible for emotion and survival instincts.
