So much could be said about the Flotation Tank, but ultimately you’ll understand it for yourself by doing it yourself.
Easy benefits to experience include Relaxation and Easing of Pain. So it’s good for people who experience stress, anxiety, depression, insomnia, or worry. Also for people who have any sorts of aches or pains (you name it, it can be eased).
The Tank is like this. When we’re inside, we cannot see, cannot hear and cannot feel (essentially). It’s also called Sensory Deprivation. By reducing the majority of physiological stimulation, we more easily notice our thoughts and emotions. We notice more who we are, and what makes us so.
I could elaborate further, but it gets a bit esoteric and so on; better IRL if you’re also interested in how it relates to consciousness and so on…
We can sort stuff out in there, gain insights and clarity, plot courses of action, Dream, and so on.
It’s very good medicine. Very high, very gentle.
