Benefits of Epsom Salt Baths
Simple yet luxurious, Epsom salt baths offer very real benefits. These soaks may effectively relieve muscle soreness, inflammatory skin conditions like eczema and psoriasis, and even arthritis, says Geeta Yadav, MD, FAAD, a board-certified dermatologist and founder of FACET Dermatology. She adds that there are also some stress-relief benefits, which are partly the physical relief but also from taking a moment for yourself.
“Magnesium on its own is also a common supplement used by those seeking a more restful night's sleep,” Dr. Yadev says. “While there's no evidence that Epsom salt baths can improve sleep, the tension and soreness relief provided by Epsom salt, plus the relaxation of being in a warm bath, [means] they certainly can't hurt!”
What Makes Epsom Salt Different
Epsom salt isn’t the same as regular table salt, so you can’t use them interchangeably for a bath. “Epsom salt is composed of magnesium sulfate, while table salt is composed of sodium chloride,” explains Maryam Safaee, MD, FAAD, a Los Angeles-based board-certified dermatologist.
“Epsom salt is naturally occurring … and used for its anti-inflammatory effects. In contrast, table salt lacks any use for medicinal benefits and instead is used mostly as a flavoring for food,” says Dr. Safaee.

How to Take an Epsom Salt Bath
Drawing a bath with Epsom salt is pretty straightforward. You just want to make sure to get the ratio, water temperature, and duration right.
1. Draw a Bath with Warm Water
Start by drawing a bath of warm to medium-hot water. “I would not go above 105 degrees Fahrenheit, as overly hot water can strip the skin of its natural oils,” Dr. Yadav says. (A standard bathtub fill-up is roughly 40 gallons.)
2. Pour in Two Cups of Epsom Salt
Next, add your Epsom salt. “Two cups for a whole bath is typically suggested,” says Erica Marie Gatt, esthetician and founder of EM Skin Studio. This is the standard amount, so start here and adjust as needed.
Tip
Doing an Epsom salt foot soak? Mix in one-half cup of Epsom salt in a basin of water. There should be enough water to cover your feet.
3. Soak for 10 to 20 Minutes
A little soaking goes a long way. Dr. Safaee says, “It’s important not to stay in the bath for too long as this can dry out the skin, so I generally recommend 10 to 20 minutes a day.”
4. Make It Relaxing
Add to the soothing effect of an Epsom salt bath by setting the mood. “Dim the lights, apply a hydrating face mask, light a candle, and breathe in and out slowly,” Gatt says.
Bonus points if the candle has a relaxing scent like lavender or rose, but whatever you have and love is a great option.
5. Rinse Off
While it’s not absolutely necessary to rinse your skin after an Epsom salt bath or foot soak, doing so removes residual salt sitting on the skin and helps minimize dryness and potential irritation. Gently rinse, pat dry, and then follow up with a moisturizing lotion or oil.

Should Anyone Avoid Epsom Salt Baths?
Most people can safely try an Epsom salt bath, but there are some considerations. “I would recommend avoiding them if you have open wounds on your skin or severe skin inflammation, such as a burn or sunburn,” Dr. Yadav says.
Dr. Safaee adds that if you are pregnant, then consult with your provider first since “a long hot bath may cause low blood pressure and cause lightheadedness.”
