Treading water, also known as "Kneipping", is a method of treatment in hydrotherapy following the methods of Sebastian Kneipp.

In the Bellavita Spa, bathers wade on stones in a Kneipp spiral. While doing this, one leg should always be lifted completely out of the water with the tip of the foot bent slightly downwards (the so-called "stork walk"). After about 30 seconds, a strong sense of cold in the feet and lower legs can be felt. After this, bathers should then leave the cold water briefly to warm up their feet. This procedure should be repeated several times.
