10 Surprising Benefits of an Epsom Salt Bath

That drugstore staple does more than just make a nice bath-time soak. See what an Epsom salt bath can do for you.

Why are Epsom salt baths so popular?

People swear by Epsom salt baths for their relaxing and soothing effects. Although some people consider them a trendy alternative for pain management, too, the jury is still out on how effective Epsom salt baths are—and how they work. If you’re dealing with any of the following issues, however, soaking in an Epsom salt bath won’t hurt and could offer some relief, according to anecdotal evidence. Here are the potential benefits.

An Epsom salt bath may ease your aches and pains

One of the most popular uses of an Epsom salt bath is to help soothe away muscle aches after a hard workout or a long day of work. Some believe that the chemical composition of the salt—magnesium sulfate—can be absorbed by the skin to help block receptors from feeling the pain. While it is true that taking magnesium blocks pain receptors, it’s not as clear if sitting in a bath is as effective, says Amy Baxter, MD, founder and CEO of MMJ Labs, and clinical associate professor with the Medical College of Georgia. So it may be the magnesium helping or it may just be the warm, relaxing bath. Either way, we’ll take it.

It may help soothe arthritis

Epsom salts can be used as a compress to help soothe aching joints. People with rheumatoid arthritis who soaked their joints in warm bath salts felt better while a control group that used plain saltwater saw no change, according to a study published in Clinical and Experimental Rheumatology. To try this at home, heat two cups of Epsom salts in a gallon of water. Then you can either bathe the affected joint in it or apply a warm compress to the area.
