If you're lucky enough to own a bathtub, you're in for a treat. Epsom salt is the perfect addition to help you relax and unwind in your bath, thanks to the stress-relieving properties of magnesium. For optimal relaxation, it's recommended to add three to four handfuls of Epsom salt to a warm bath and rinse off with clean water afterward. External use is not recommended for people with edema, heart problems, high blood pressure, or kidney failure. Similarly, if you have skin conditions (lesions, psoriasis, eczema), consult your doctor before using it in your bath.
