Chromotheraphy has been studied and practiced for more than 4,000 years. Once reserved for the pharaohs of Egypt, this healing technique is now possible in our own homes to help improve our health and daily outlook. Often, the shower can be the best place to get a dose of healing light without breaking a daily routine. A multitude of colors can be produced with the aid of low-voltage LEDs (light-emitting diodes). This little bit of extra lighting does wonders for a small shower or bathroom — the ability to layer the light to suit morning routines or lazy weekend soaks is key to enjoying the bathroom at different times of day. Add in a little colored light, and you have a whole new space.
