The salt used to create buoyancy in float tanks is magnesium sulphate, commonly known as Epsom salt. The high concentration of salt (approx 600kg) is what creates the weightlessness within the water. Epsom salt relieves aches and pains, helps detoxify the body, and improves overall health. Magnesium is the second-most abundant element in human cells and the fourth-most important positively charged ion in the body. It helps regulate the activity of more than 325 enzymes and plays a vital role in numerous bodily functions, including muscle control, electrical impulses, energy production, and the elimination of harmful toxins.
Magnesium sulphate also flushes out toxins, improves nutrient absorption, aids in the formation of joint and mucin proteins and brain tissue, and helps prevent or ease migraine headaches. Essentially, we need magnesium sulphate, yet most of us are deficient due to depleted soil. Fortunately, it is absorbed transdermally through the skin during float therapy.
