Natural Lighting: A New Light for Learners

There’s a clock inside every classroom that defies even the most ardent clock watcher. It’s known as the body clock. Every human being has one. It’s part of our natural biology.

Body clock is another name for circadian rhythm, the world’s most efficient natural timekeeper. Circadian rhythm is the biological force that tells us when to feel sleepy and when to feel awake. Central to this sleep cycle is blue (daytime) light. Blue waves stop our bodies from producing the neurochemical, sleep aid melatonin and stimulate serotonin production, the neurochemical that help us be more alert in the early hours of the day.

When blue light vanishes with the setting sun, the melatonin flows again and the eyelids droop. Ever notice how much sleepier you feel during the darker autumn and winter months? Fewer sunlight hours is the likely explanation.

For students, class time means long stretches indoors, where natural light is hard to come by, even with windows open. While most indoor lighting does emit blue light similar to the sun, it’s not enough to replace natural lighting.  Studies now show that a lack of natural light contributes to fatigued minds.

Blame the Bulbs

Conventional bulbs are typically harsh on our eyes and generate insufficient amounts of blue light. Result? Confused, worn out brains, short attention spans and lack of concentration. Not exactly the ideal formula for receptive learners.

Improved Learning with Natural Lighting

Realizing the negative impact improper lighting has on learning, educators and administrators are exploring possible solutions. One of the most promising to emerge is the LED light bulb. Capable of synchronizing with the natural circadian timetable, LEDs can help students maintain expected daytime alertness and energy levels.

We have  been at the forefront in the search for improved classroom lighting solutions. After years of intensive research, our team has developed a blue-enhanced LED, well-suited to learning environments. In tune with circadian rhythms, these innovative ‘daylight’ bulbs reduce fatigue and enhance the body’s natural alertness in both students and educators.

Our Awake & Alert™ Light, utilizes a patented spectrum filter to maximize blue light. Early results have been encouraging. In a recent study at Bishop O’Connell School in Church Falls, Virginia, Awake & Alert™ lights were installed in a middle school classroom. In the following quarter, teachers noticed students are far more alert, and grades have improved (on average from a C to a B GPA).  Who would have thought being awake during class time would help?

While further testing and investigation is needed, of course, these early findings clearly suggest a correlation between biologically-correct LED bulbs and student productivity.
