Epsom Salts: A Favorite Remedy For Anxiety, Inflammation & Insomnia

Over these years of research and personal experimentation, Epsom salts have become one of my absolute favorite "alternative" remedies. Although I'm not sure we should even use the word "alternative," seeing as magnesium-based therapies have actually now been approved by the FDA as laxatives and you can find Epsom salts in pretty much any pharmacy or grocery store in America. They're a great remedy whenever you're amped at the end of the day, sore from a workout, or just in need of a little extra self-care.

The history of Epsom salts is pretty fascinating. They were discovered as early as the 1700s in a town called Epsom (big surprise there), which is about 15 miles from London. People would travel from all over Europe to bathe in the healing water at the bitter saline spring in the town, which would help with anything from skin issues to wound healing and decreasing infections to digestive problems. Eventually, they discovered that boiling down the water produced magnesium sulfate salts, later named Epsom salts, which were then able to be transported and sold everywhere. Epsom salts—much like witch hazel—have withstood the test of time and are still a popular remedy today that has been embraced by both Eastern and Western medicine practitioners.

Here are some of the most common reasons why people are using Epsom salts baths on the reg:

One of the first benefits of Epsom salts that was discovered was its ability to act as an all-natural laxative. Today, however, it's not recommended to use Epsom salts internally as a laxative. Instead, there are other forms of magnesium that can help keep things moving along your digestive tract in a way that's a lot more gentle. Magnesium citrate, which is available in a supplement capsule or as a powdered drink, is one of the top doctor-recommended forms of magnesium for constipation, along with magnesium oxide.

One of the best benefits of magnesium and Epsom salts is their ability to help wash away the stress from the day and soothe occasional anxiety3. Magnesium is often praised as one of the best natural approaches to anxiety, stress can be a risk factor for magnesium deficiency, and ironically, a deficiency in magnesium can magnify our unhealthy responses to stress. Top integrative medicine doctors think we need more magnesium in times of stress, explaining that it interacts with GABA in the brain.

Knowing magnesium's ability to soothe tense muscles and relieve anxiety, it probably comes as no surprise that it is also praised for helping with sleep. One study showed that elderly people taking a magnesium glycinate supplement had improved insomnia4.

Magnesium is frequently used as a remedy to relieve pain from things like muscle cramps and menstrual cramps5, and low levels of magnesium in the blood have been linked to migraine headaches.

People have been using Epsom salts to heal the skin for as long as they've been around. A study published in 2005 suggests that Epsom salts can be helpful if you have dry skin and can decrease inflammation and promote hydration.

Epsom salts are also a great way to help your body detox and support the liver. Will Cole, D.C., IFMCP functional medicine expert and mindbodygreen Collective member is a big fan of Epsom salts, "I seriously love Epsom salt baths. Most people today are magnesium deficient and Epsom salt baths are one great way to increase magnesium levels. Magnesium is essential for hundreds of important pathways in our body, one of which are detoxification pathways. In addition to being nature's chill pill, magnesium is extremely important for sulfonation, glucuronidation, and glutathione conjugation reactions which are all part of phase II liver detox pathways." He frequently recommends Epsom salts to patients at his functional medicine clinic.

If you want to bring your bath to the next level, try adding a few drops of lavender or chamomile essential oil or one of these PureSoma soaks that feature different herbs, clays, and minerals that can also help with recovery, sleep, or detox.

One note: Excess magnesium is excreted7 through your urine, and magnesium balance in the body is controlled by the kidneys, so if you have a kidney issue, you'll want to talk to your doctor before supplementing. In fact, it's always best to mention to your doctor when you're thinking of taking a new supplement and to make sure it's on your chart if you're already taking it.

Want one last Epsom salt tip? Leave the phone out of the bathroom while you soak—you're taking away some of the benefits when you're reading the news or scrolling through social media. Instead, sit in silence, listen to some calming music, or try a guided meditation.
