Floating is still a relatively little known relaxation technique. Although it was already invented in the second half of the 20th century, it still does not reach wider awareness of both the public and professionals. The principle of this technique is to stay in an undisturbed environment of a water tank in the shape of an egg, filled with a dense saline solution allowing „floating“. Hence the name of the technique itself. The conditions of this technique, restricting intrusive external stimuli, allow the experience of deeper relaxation than commercially available relaxation methods. This paper focuses on reminding and mapping existing knowledge of the relaxing effect of floating. In the text, sufficient space is dedicated to the description of this technique, to the method of its use as a relaxation tool and also to the historical context of the development of floating. A final part treats the rules for the use of this technique and potential risks associated with it.
