We’re all familiar with the expression, “Early to bed, early to rise, makes a man healthy, wealthy and wise”. Not too long ago, the majority of humans were naturally early to bed and early to rise since the only light source after sunset required constant fuel sources, which were labor intensive en masse.

Now, in the post-industrial era, humans use artificial light to stay awake 24-hours a day, which has completely altered our natural bio-rhythms. This can have negative consequences on sleep patterns, among other health issues. As a result, researchers discovered changing the quality of artificial light throughout the day, via dynamic lighting technology, allows the human body is able to return to a more normal biorhythm again.

For a more detailed report regarding the findings, you can read Dynamic Office Lighting on licht.de., but the general gist is that the more techies altered artificial light sources to mimic the sun’s intensity at corresponding times of the day, office workers were more productive, slept better and felt better in their day-to-day lives.

This is great news to everyone, from top to bottom of the professional spectrum. The more we can use technology to the benefit of both company and employee health, the better. One example from lict.de is a company in Hamburg that has made the switch to dynamic lighting. While the system increased energy consumption by 25%,  the company has noticed equivalent increases in productivity. We can only imagine the technology will become increasingly more efficient over time.
