Epsom salt contains magnesium and sulfate. Both substances have beneficial properties that can improve various body functions. Combining magnesium and sulfate can also help your body release toxins.
This article reviews the health benefits of bathing in Epsom salts and how to use them.
What are the benefits of Epsom salt baths?

Epsom salts have a variety of health benefits. Their use can range from treating skin irritation to improving muscle and joint pain. People can also use Epsom salts to exfoliate or as a cuticle softener as part of their skin care routine.
Your skin may absorb magnesium sulfate salt during an Epsom salt bath, which can help regulate the activity of around 300 of the body’s enzymes. Magnesium deficiency could lead to health complications, such as:
- high blood pressure
- heart conditions
- osteoporosis
- migraine headache
Sulfate, a combination of sulfur and oxygen, can play an important role in helping your body flush toxins and maintain your skin’s health. Sulfate may also contribute to improving joint and bone health.
However, more research is necessary to prove the health benefits of Epsom salts.
Carrying important ions
Magnesium has an important role in carrying potassium and calcium ions across cell membranes. This is vital for regular heart rhythm and may help to prevent cardiocirculatory conditions. It is also important for nerve impulse conduction.
Muscle contraction
Magnesium is important in regulating muscle contractions. For this reason, having Epsom salt baths may help relieve muscle pain and cramps. The magnesium in Epsom salts may also help prevent cardiocirculatory conditions, helping maintain a healthy heart rhythm.
Diabetes
People with diabetes may also benefit from Epsom salt baths as the magnesium may help make insulin more effective and improve blood sugar levels.
Stress and relaxation
Regular Epsom salt baths may help reduce stress and relax the body.
Psoriasis
According to the National Psoriasis Foundation (NPF), Epsom salt baths can soothe itchy skin and help to remove the scaly skin associated with psoriasis.

A doctor or healthcare professional may suggest taking magnesium supplements if you are magnesium deficient.
You can also take magnesium sulfate orally to help relieve constipation. However, you should contact your doctor before using Epsom salts to relieve constipation or if you have any other underlying conditions.
How to use Epsom salts in a bath
To prepare an Epsom salt bath, you should dissolve 1–2 cups of Epsom salt into warm bath water. You can also add some essential oils, depending on your preferred scent.
When the Epsom salt is dissolved, enter the bath, relax, and soak for at least 12 minutes. Your skin may have the ability to absorb the minerals, such as magnesium, while you are soaking.
Afterward, you can rinse your skin with water to remove any excess salt.
If you have an underlying medical condition or are unsure if Epsom salt minerals will interact with your medications, you should contact your doctor before using Epsom salts.
Finally, high magnesium levels, also known as hypermagnesemia, can cause serious health complications. Always follow the directions on the pack or the advice and guidance from a medical professional.
Are other salts beneficial?
There are other types of salt that may benefit your health. One of these is black salt, also known as Himalayan black salt, which is a type of salt with antioxidant properties that could boost your health, according to an in-vitro study.
Himalayan black salt also has significantly low levels of sodium when compared to regular table salt. It contains high levels of calcium, iron, and magnesium, which may contribute to your recommended daily intake of these minerals.
However, more research about the beneficial properties of black salt is necessary.
Summary
More research is needed to establish the scientific benefits of Epsom salt baths for improving health. However, some studies show regular Epsom salt baths may result in pain relief and muscle relaxation. The warm temperature of the bathwater may also play an important role in relaxing your muscles and reducing joint inflammation.
Magnesium sulfate is one of the main minerals in Epsom salts, and your skin may be able to absorb it while you soak. This could increase magnesium levels, which is important for maintaining a regular heart rhythm and nerve and muscle function.
Other types of salt, including Himalayan black salt, may also help with your recommended mineral intake.
If you have any concerns about Epsom salts interacting with a medication that you regularly take or you have any underlying condition, you should contact your doctor to check if Epsom salts are safe for you to use.
