Medical explanation of the effect of light therapy
Today we know that sun light acts like a natural clock for many of our physiological processes. Bright light travels in the
form of electric impulses via the eyes and the optical nerves to the nervous system's inner timer in our brain. This "time
giver" processes the information about light and darkness and instructs other parts of the brain to rhythmically distribute
chemical messengers. Bright light thus stimulates the production of chemical messengers which influences the mood and
suppresses the production of the body's sleep inducing hormone.
