The new health gadget by Valkee company was developed to help you cope with those moods swings and depression associated with SAD. The device is a brain stimulation headset that beams light right into your ear canals and into your mind.
The development of the device is based on the studies conducted by the University of Oulu in Finland that show that our brain is photosensitive. The recent trials of bright-light headset showed that shining light into your ear canal even more effective than delivering it through your eyes. Light stimulates our biological processes and production of serotonin and melatonin that are responsible for our good mood.
During the trials people suffering from SAD reported 80 to 89 percent improvements in SAD and half of the participants reported about relief in anxiety disorder.
