Epsom Salt – To Soak or Not to Soak
Epsom salt, named for a bitter saline spring at Epsom in Surrey, England, is not actually salt but a naturally occurring pure mineral compound of magnesium and sulfate. Long known as a natural remedy for a number of ailments, Epsom salt has numerous health benefits as well as many beauty, household, and gardening-related uses.
Studies have shown that magnesium and sulfate are both readily absorbed through the skin, making Epsom salt baths an easy and ideal way to enjoy the associated health benefits. Magnesium plays a number of roles in the body including regulating the activity of over 325 enzymes, reducing inflammation, helping muscle and nerve function, and helping to prevent artery hardening. Sulfates help improve the absorption of nutrients, flush toxins, and help ease migraine headaches. ~ SaltWorks
These are the first two paragraphs on a website that describes and embraces the virtues of epsom salt. (They also sell a variety of salts for cooking and therapeutic benefits.)
For several years, I’ve been enthusiastically recommending epsom salt (magnesium sulfate) baths and foot-soaking to relieve muscle aches and pains and to speed up recovery after a series of challenging workouts. My own experience supports the use of epsom salt but what does the critical scientific research say? I was surprised at the volume of information and the lack of a consensus.
So, to soak or not to soak? That is the question.
The answer? My advice is to soak. At least try it. Here’s why. Your great-grandmother did it. Your grand-mother did it. Maybe your mom did it. Maybe they did it because it works. I do it because it works for me. I can tell you that a foot bath with 2 cups of epsom salts in about a gallon of water makes my feet feel amazing after about 12-15 minutes of soaking.
The crux of the matter: If transdermal absorption of magnesium works, you’re helping to remedy a potential electrolyte imbalance that will help relax (and maybe hydrate) tissues that are sore, cramped and likely leading to other issues including movement compensations that can have further implications up the kinetic chain.
Here are some of the articles I’ve referenced to write this post:
- Magnesium deficiency and metabolic syndrome: stress and inflammation may reflect calcium activation.
- Magnesium and the regulation of muscle contraction.
