binary trades A school system was in the process of building five new schools to house their increasing student population. Having read the research on the detrimental effects of fluorescent lighting, I shared with the architects rationales for including additional windows or a different type of lighting in the construction of these new buildings. The experts thanked me for my input but proceeded to include fluorescent lighting in plans for each of the five new edifices. You see, this type of lighting is less expensive. While fiscal responsibility is certainly warranted, the increased expense may be offset by decreases in misbehavior and ill health and increases in academic achievement.

Additional neuroscientific research reinforces that the best light for the brain is natural light. It stands to reason that, if the purpose of the brain is to help the body survive in the world, then natural light, such as sunlight, would be optimal. If your classroom has windows, open the shades, and let the light shine through.

If this is the case in your environment, try bringing alternative lighting or lamps into your classroom. Even turning off half the fluorescent lights and supplementing with lamps is helpful. This practice alone appears to reduce behavior problems because the lower lighting calms the brain – a preferable state for optimal learning. In fact, lamps also give the classroom a homelike atmosphere, which is more natural for brains.

Fifteen percent of the population is impacted by seasonal affective disorder (SAD), which is a form of depression that results when people are deprived of daylight for long periods of time. Cognitive problems that may accompany SAD include lapses in verbal and visual memory and lack of attention.

- If you only have one switch to your fluorescent lights, turn it off, and bring lamps into your classroom. Certain types of floor lamps may have several separate light sources and can be directed to different areas of the room, thereby providing illumination to more students. If lamps do not provide sufficient lighting, explore the possibility of unscrewing the bulbs in half of your fluorescent lights and using a combination of both ceiling lights and lamps.
- Convene some classes outdoors so that students can take advantage of the natural ultraviolet light from the sun. The research is showing that doctors may have to start prescribing doses of Vitamin D for today’s children because they are not getting sufficient doses of it from playing outdoors in the sun.
- When students are not getting a sufficient amount of light, and you are unable to take them outside, allow them to engage in movement connected to learning and other types of physical activity in the room. The activity will produce chemicals in the brain, such as epinephrine and dopamine, which can combat depression.
