Color Therapy Jacuzzi, Gurney's Inn Resort & Spa, Montauk, LI, NY: Florence Nightingale, the legendary nurse who worked during the Civil War, wrote in her notebooks, "Patients who had colorful items around them improve faster." With the scientific proof of biological energy fields, color therapy uses color to attempt to make changes to vibrations in the body. Each color of the spectrum has its own specific frequency that corresponds to one of the body's seven chakras. The body's organs and systems have their own resonant frequencies related to the Chakras. The color therapy tub produces a sequence of colors while relaxing in the whirling water.
