Color light therapy is known as chromotherapy. It’s a centuries-old practice in which certain colors and light are utilized to adjust and re-balance bodily frequencies and energy stores for better health and relaxation. If your energy levels are blocked or depleted, it’s more difficult for your body to function properly, which can lead to a variety of health issues. Chromotherapy is backed by studies that have shown colors have a profound effect on us at all levels—physical, mental, and emotional. Combining color light therapy with heat therapy can enhance a sauna’s health benefits and healing properties.The colored LED light comes in 2 sizes — 30” and 51” to fit both small and large saunas. As for placement, it has been designed to fit behind the heater in barrel saunas, and behind the backrest in indoor saunas. The LED color-changing light comes with remote control. Using it, you can conveniently control the 20 different light options, color intensities, and transition patterns from anywhere in the sauna.
