The health benefits of Epsom salt date back to their discovery in the English town of Epsom during Shakespearean times. Soaking in Epsom salt can reduce swelling, ease muscle and joint pain, and help your circulatory system function more effectively, according to the Epsom Salt Council.
In the Bath
Fill a bathtub with warm water. The water should be warm, but not too hot.
Add 2 cups of Epsom salt to the running water. If you have an oversized bathtub or a garden tub, double the amount of Epsom salt to 4 cups.
Soak for at least 12 minutes and ideally for 15 to 20 minutes, three times a week for maximum benefits.
In a Foot Tub
Fill a foot tub with warm water so that it's deep enough to completely cover your feet.
Add 1 cup of Epsom salt to the warm water, using your hands to mix the salts into the water.
Submerge your feet in the warm water for 12 to 15 minutes.
Repeat three times a week or as needed.
