Thanks to our modern lifestyle, most people suffer from some degree of light deprivation and an unbalanced circadian rhythm. This is characteristic for the Northern latitudes where the winters are especially dark, but also in more sunlit parts of the world, people working indoors typically don’t get enough daylight. For instance, in San Diego, California, the average citizen gets less than one hour of daylight per day.
It is becoming increasingly clear that numerous biological processes in the human body depend on sufficient exposure to the right types of light. Extensive research is currently conducted into the effects of light on our mental and physical wellbeing, in particular of the blue part of daylight.
Daylight stimulates, influences and controls many of our physical and mental processes: Sleep, Energy level, Brain activity, incl. ability to concentrate, Mood, Digestion and the Circadian rhythm.
