When we take a warm to hottish bath with Epson salts, the body will sweat due to the warm water, through the sweat many of the metabolic wastes will be flushed out. Through your warm skin, the Epson salt will go into your system and rebalance the chemistry of your muscles. This is an extension of your massage treatment. Taking a bath after a deep tissue massage will decrease the possibility of muscle soreness the next day. This muscle soreness is due to the accumulation of metabolic waste that is created during the massage treatment.
