The Benefits of Full Spectrum Lighting

Does the lack of sunlight in the winter influence your mood? Does extended time at a computer make you fatigued or irritable? Do you feel sleepy and fatigued at work? You are not alone. We spend an inordinate amount of time indoors, under artificial light. Wintertime can be especially challenging, as our exposure to natural daylight is reduced. Just like clean air and water, our bodies need natural daylight, it can be as important as any nutrient. Extensive research indicates that we need at least 2 hours of light exposure each day to function normally. When it starts to get gray and dreary outside, or when we spend too much time under fluorescent light, our bodies respond to this change. Our productivity and sense of well being can be compromised.

 

Let there be light

In the beginning God created the heaven and the earth. Now the earth was unformed and void, and darkness was upon the face of the deep; and the spirit of God hovered over the face of the waters. And God said ‘Let there be light.’ And there was light. And God saw the light, that it was good; and God divided the light from the darkness. – Genesis

For centuries, we have woken with it; it marks and measures the length of our days and the changing of our seasons, locking us into the rhythm and heartbeat in the nature of life. We respond both culturally and biologically; we follow the patterns that date back to the beginning of time.

Light enters the eye and is translated and interpreted by millions of specialised cells in the visual system. It gives our world shape, depth and colour. It gives us great pleasure in many forms, sharing a smile; watching billowing clouds in the blue sky and even on to reading a book.
