This is the relaxation system that uses sound and light to help calm the mind, improve sleep and mood, and reduce stress. Available exclusively from Hammacher Schlemmer, the cerebral spa consists of high response earbuds that play soothing tones and rhythms, combined with LED-embedded goggles that flicker with rhythmic light patterns. It includes 18 free downloadable programs—six for light meditation, six for deep relaxation, three for sleep enhancement, and three for cognitive stimulation—that combine to train the mind and massage the mood. Selecting white lights, for example, helps decelerate racing thoughts, similar to being transfixed by a campfire, while audio stimulation helps boost the brain’s alpha waves, which are associated with creativity, relaxation, and decreased anxiety. In contrast, selecting blue lights and sound stimuli help reset your internal body clock for help overcoming winter “blues” and jet lag. Sessions last from 11 to 69 minutes; most people see and feel results in 4-6 weeks of regular use. Rechargeable li-ion battery provides up to two weeks of daily use on a full charge via the included USB cable. Comes with travel bag. 2 1/4" L x 2 1/4" H x 3/4" D. (7 oz.)
