Bodies physically rest and recover more quickly in a floatation tank, up to four times faster, in fact. This means that you can train yourself harder and reap the benefits of slower recovery times with the use of a float tank. Water in the float tank has the added benefit of being saturated with Epsom salts, which have well-established healing effects, helping to draw out toxins and lactic acid from work outs, speeding up recovery time and allowing athletes to push themselves farther, faster, especially in conjunction with massage or other alternative medicine.
