In the sensory-deprived environment of a float tank, the brain and mind can more easily enter a deeply relaxed and meditative state.
Research has shown that floating reduces levels of the stress hormone cortisol, lowers blood pressure, and can alleviate pain.
With sight, sound, and touch minimized, both mind and body are able to fully rest from external stimuli. In this deeply relaxed state, the body releases substances that help to reduce stress and anxiety. A relaxed mind finds it easier to let go of worries and stop dwelling on the past or future. When we achieve a “here and now” state, the brain and mind, as well as the body, receive the rest they need.
The deeply relaxed state achieved through floating can also help the mind open pathways to new insights and discoveries, enhancing creative thinking, learning, visualization, and problem-solving. Many people find that floating, beyond just reducing stress and anxiety, is among other things an effective tool for mental visualization and creative projects.
For this reason, float tanks are often referred to as “think tanks,” as many floaters experience insightful thoughts and fresh perspectives on both everyday concerns and deeper themes of self-exploration during their float.
