Beneficial effects of treatment with sensory isolation in flotation-tank as a preventive health-care intervention – a randomized controlled pilot trial
BMC Complementary and Alternative Medicine October 25, 2014 A. Kjellgren, Jessica Westman
A series of twelve flotation tank sessions over seven weeks significantly reduced stress, depression, anxiety, and worst pain, while increasing optimism and sleep quality in healthy adults. No significant changes occurred in a wait-list control group. A correlation was found between mindfulness in daily life and the degree of altered states of consciousness experienced during flotation. The findings suggest flotation-REST has beneficial effects for relatively healthy individuals.
