Simulation of sunset and sunrise

Light stimulation decreases the production of the sleep hormone melatonin and increases the production of happiness hormone serotonin. Sunset/sunrise-treatment will simulate a sunrise and combine light stimulation with archaic sounds and music composed specially for the purpose.
Sound images will move in strength up and down, depending on how strong the light intensity is. “The sun” will move up or down in intervals from ten minutes to four hours. The user will be able to choose colors and musical compositions or any of nine pre-programmed settings.
The treatment will be developed with the purpose to counteract:

sleeping problems
a lack of energy
difficulty in concentrating
nervousness/ fear
problems with the immune system
mood swings
