BMC Complementary and Alternative Medicine published their results of a study done on the ‘beneficial effects of treatment with sensory isolation in floatation-tank as a preventive health-care intervention’ in the year 2014. As few studies had been done at the time, Jessica Westman and Anette Kjellgren decided to investigate floating and its effect in healthy participants.
They had 65 participants, where 14 of them were men and 51 were women. The period of study consisted of a seven weeks floatation program with twelve floatation sessions in total.
The participants filled out questionnaires that measured psychological and physiological variables including energy and stress, anxiety and depression, optimism, pain & sleep quality. They also investigated mindfulness and the degree of altered states of consciousness that were being used. All the data Kjellgren and Westman received from their study showed clear results. Worst pain, stress, anxiety and depression were decreased, while optimism and the participants quality of sleep increased. During the relaxation in the floatation tank, the connection between mindfulness in daily life and the degree of altered states of consciousness became obvious. Their conclusions from their research and this study proved that floating had beneficial effects on these moderately healthy participants.
