Unlike lightning, which slays wherever it strikes, light heals all that it touches and can turn a thundercloud's upset stomach into a beautiful rainbow. Let restorative rays of light soak your skin with today's Groupon: for $25, you get one session of UV-free light therapy (a $50 value) at Inland Massage Institute on East Holland Avenue.

Full-spectrum light is essential to the human body, and Inland Massage Institute gives clients a new way to weather days of darkness with the Sunspectra 9000—a technologically advanced machine that mimics the sun's mood-boosting rays. During your 45-minute photic-therapy session, high-tech shinings will gently restore the delicate corporeal balance of brain chemicals, which run amok when the body is denied its recommended dose of sunlight. Lay back and bask in a bath of blues-banishing, UV-free rays as you're recharged and relaxed by Sunspectra's gentle glances.
