To understand why natural light is so important, we need to think of our ancestors. Before we had electrical light humans spent 90% of their awake hours outside. Being outside they were surrounded by natural, dynamic (constantly changing) light. They enjoyed the warm sunrises, bright blue mid-day lighting and then the warm glow of sunsets. Once inside they had the warm light from candles or fires.
Our biological time clock, Circadian Rhythm, is reset each day by natural lighting. As we fast forward to today, we are spending more than 90% of our time indoors under static (non-changing) light. A study done by UNC Kenan-Flagler Business School found that the color temperature of the light source has the most influence on how we work. They believe that it’s in our DNA to perform better under specific lighting.
