Epsom salt, or magnesium sulfate, is an alkaline chemical compound that is safe and can aid the body in many ways, according to the Epsom Salt Council. A study conducted by the University of Birmingham noted that Epsom salt's magnesium is easily absorbed through the skin and directly beneficial to the body. Benefits include the relief of sore muscles and joints, increased ability to flush toxins, and relief from joint problems. This useful chemical salt is believed to have earned its name from the English town of Epsom where it was originally discovered.
Chlorine and magnesium should never be mixed, as the reaction it causes can result in serious injury caused from flash burns. So, Epsom salt is not safe to use in a chlorinated hot tub. If you would like to introduce Epsom salt into your chlorinated hot tub, you'll need to first drain and thoroughly rinse the tub and the tub's equipment and refill with pure water instead.
Epsom salt is safe to use in a plain water hot tub. In order to avoid adding too much and causing possible corrosion to your tub's equipment, only add the manufacturer's recommended amount. For the full benefit, soak in the water for a full 30 minutes with the jets rotating the water.
Epsom salt is a highly corrosive chemical that can build up in your spa's equipment. To prevent buildup, always flush your hot tub with fresh water after each Epsom salt bath. Additionally, do not add any other substances to the hot tub when using Epsom salts to prevent unexpected chemical reactions. Before adding Epsom salt to your hot tub, check with your manufacturer for any further precautions.
Epsom salt can increase your body's magnesium levels. The National Academy of Sciences reports that raising your magnesium levels can improve heart health, improve the body's insulin use and aid in flushing out toxins from the body's cells. Epsom salt is also often recommended for stiff or sore muscles and tendons.
