For those who enjoy longer-than-necessary showers, Vichy takes the bliss factor to the next level. Akin to having a horizontal shower, it involves lying down on a padded table while alternating streams of hot and cold water pulse and gently knead the body. Hydrotherapy has many known benefits and the pattern, placement and temperature of the jets are adjusted throughout the treatment to help boost blood circulation, detoxification, skin hydration and elasticity, and decrease stress by relaxing muscles and soothing the nervous system. Towels are strategically draped to protect modesty, and some spas include a simultaneous full-body exfoliation and massage (say yes). The experience is highly soothing and indulgent, and feels like floating in a warm, steamy cocoon. Don’t be surprised if you’re lulled into a semi-conscious state.
