The eyes are the window to the soul, but where would one look to find out what’s going on inside your body? Get yourself over to Be You Bi Yu Wellness Center & Spa for the FootSpa detox treatment and you’ll soon find out. Plop down and soak your feet in a warm, saltwater bath. Meanwhile, a special device will release positive ions into the water that draw pollutants out of your system through your toes. (Sure, it sounds like hocus pocus; just bear with us.) The aim of this detox is to strengthen your immune system, improve flexibility, alleviate stiffness, and give you an overall feeling of well-being. Plus, they’ll examine the debris from toxins like heavy metals, yeast, tobacco, and alcohol that end up in the bottom of the tub and tell you just what you’ve had too much of. As if you didn’t know already. Be You Bi Yu Wellness Center & Spa, 5602 Shields Drive, Bethesda (301-493-4911 or beyouspa.com).
