Natural Lighting is Better Than Artificial Indoor Lighting

Daylighting is the practice of using natural light to illuminate indoor spaces, achieved through the right choice of windows and proper window placement. Aside from making indoor spaces look bigger and more inviting, it also offers other benefits that make daylighting a preferable choice over artificial lighting.

Artificial Indoor Lighting

Let us share what these benefits are:

Health Benefits

In recent years, daylighting has been the subject of several studies exploring its effects on human health. Here are some of the most notable findings:

  • It increases patient recovery rate – In a 1984 article published in Science magazine, surgery patients have been found to recover about 8.5% faster when placed in daylit rooms. These same patients also required fewer painkillers compared to other patients in rooms whose views were nothing more than a brick wall.


  • It helps create a better study environment – The results of a 1999 study conducted by the Pacific Gas and Electric Company showed a high correlation between high test scores and daylit classrooms. A 2002 follow-up study, published in Leukos (the official Illuminating Engineering Society journal), further confirms this effect.


  • It helps promote healthy amounts of sleep – Several studies produced conclusive evidence that daylighting is essential to regulating human body clocks. People who worked in windowless offices and other places where exposure to daylight isn’t possible tended to have disrupted sleep cycles, which could lead to chronic sleep debt.

Lower Energy Consumption

The more you use natural light, the less you need artificial daytime lighting. You may think that you’ll need a bank of floor-to-ceiling windows for this to work, but just a few, well-placed gliding windows are more than enough for a large room. Reduced indoor lighting can result in significant energy savings.
