Lighting Matters: The Top 7 Ways Lighting in a Classroom Can Affect Teachers

Teachers have a considerable amount of influence over their classroom environment. Some teachers pay closer attention to the details of their environment that others commonly overlook, including the negative impact of lighting in the classroom.

 

If you’ve been investigating the many benefits of filtering the fluorescent lights in your classroom, you are likely aware of the many advantages of transforming visible light for the benefit of your students.

Since teachers often prioritize the needs of their students over their own, you may not be considering the potential impact of unfiltered light on your own health and wellbeing. Here are the top seven reasons classroom lighting matters for you as much as for the students you teach.

Classroom Lighting Can Sabotage Your Classroom Performance

Natural light contains all the colors of the visible light spectrum with equal intensity. So does incandescent light.  Fluorescent lights are different. Fluorescent lighting provides light in a limited color spectrum. These limitations can have a distinct impact on moods, emotions, hormone regulation, and even sleep cycles.

To give your students the best you have to offer, you have to feel your best.

Since fluorescent lighting can influence the way you feel, the lighting in your classroom could be sabotaging overall classroom productivity, your students’ and your own. If you work under the harsh glare of fluorescent light, you may recognize some of the following effects.

1. Your Lighting System can Trigger Headaches

The fluorescent lights found in most classrooms are a common trigger for headaches and migraine. Researchers commonly believe that people living with migraine pain are sensitive to the color temperature and subliminal flicker of fluorescent lights. Those living with migraines are not the only people impacted. Poor lighting conditions are also known to trigger:

While fluorescent lights have improved over the years, it’s important to note that even “flicker free” bulbs send chaotic messages to your brain.

While you can’t see the flicker, the chaotic signals can also cause fatigue and irritability.

#2. Lights Can Contribute to Light Sensitivity

Many teachers working under the harsh glare of fluorescent tubes or LED technology notice that their eyes feel tired, sore, or even painful by the end of the day.

If you are sensitive to bright lights, you may also notice that your eyes tear when exposed to certain lighting conditions.

The medical term for light sensitivity is photophobia. The symptoms of photophobia can be instantaneous with exposure or escalate throughout the course of the school day. If you are experiencing light sensitivity, you may recognize some of the following symptoms:

When you have a headache or are toughing out a migraine, you likely find it more challenging to connect with your students or enjoy the progress made during the day.

Many teachers who are sensitive to fluorescent light find that installing classroom fluorescent filters eases their discomfort and can improve student performance.

#3. Fluorescent & LED Lights Can Intensify Stress Levels

Many of the hormones responsible for regulating your moods and emotions are influenced by sunlight, including your stress hormones. The color spectrum of the light emitted from your classroom lighting can suppress hormone production.

Fluorescent light is shown to inhibit natural cortisol production, the hormone responsible for the fight or flight response triggered by stress. While this may seem beneficial, cortisol suppression is actually counterproductive.

When cortisol production is suppressed, it becomes increasingly difficult for your body to deal with everyday stressors. As a result, your stress levels can continue to rise. In addition to regulating your body’s reaction to stress, cortisol also plays a significant role in the following functions:

If indoor lights are interfering with your body’s ability to regulate stress, you may notice that you feel increasingly more stressed during the day. You may also notice an increase in food cravings and decreased energy levels. While your students may not be aware of your food cravings, they are likely to pick up on your increasing stress levels or fatigue and respond accordingly.

#4. Can Interfere with Sleep Cycles

The area of your brain that influences your sleep cycles is regulated by the natural progression of sunlight, full-spectrum light. Limited exposure to can interfere with this essential regulatory process.

Fluorescent light exposure suppresses melatonin production. Melatonin is the hormone that regulates sleep.

If you have trouble sleeping in spite of the physical and emotional demands of the classroom, you could be feeling the effects of sleep cycle dysregulation caused by fluorescent lighting. If  your sleep is being affected, you may be far too aware of the following symptoms of sleep deprivation:

While daytime exposure to overhead lights can affect hormone regulation, you may notice that it’s the evening activity, the extracurriculars or parent/teacher conferences, that will disrupt your ability to fall asleep the most.

The effects of sleep deprivation are cumulative. Sleep deprivation can increase your risk of serious health complications including heart disease, high blood pressure, diabetes, and stroke.

Are fluorescent lights making you tired?

Do you feel sleepy towards the end of the school day? Your lighting may be robbing you of a restful nights sleep.

#5. Fluorescent Lighting Can Increase Your Risk of Eye Problems

The light emitted from your classroom lighting fixtures utilizes two types of energy. Electrical energy interacts with gasses in the fluorescent tube to generate ultraviolet light, the same type of energy emitted from the sun.

The phosphorous coating of the bulb absorbs the UV rays and emits visible light.

Many teachers underestimate the potential impact of indoor UV light exposure on their health. A 2011 report published in The American Journal of Public Health estimates that prolonged, consistent fluorescent light exposure increases your risk of eye disease by up to 12 percent.

The lighter your eyes, the more susceptible they are to damage. Prolonged, daily exposure to fluorescent lighting can have significant consequences, including:

To protect the health of your eyes, it’s important to minimize UV exposure. Outdoors, UV blocking sunglasses are ideal. Indoors, consistently wearing dark glasses can increase light sensitivity. UV-blocking fluorescent light filters may be your ideal solution. By blocking UV rays, you will be protecting your eyes from cumulative damage.

#6. Classroom Lighting Can Accelerate Skin Aging

While fluorescents are designed to absorb UV radiation, the phosphorous coating protecting your skin is vulnerable to damage. It appears that the risk of indoor exposure is more significant than once believed. Age decreases the protective phosphorous coating of fluorescent bulbs. UV exposure: even low-dose exposure, can  your skin.

Your skin needs protection from UV rays whether natural or man-made. Consider the following effects of UV rays on the appearance of your skin.

If you have a chronic skin condition, UV exposure could make your symptoms worse. Indoor UVB exposure can also trigger rashes, skin lesions, and joint inflammation in those living with lupus and negatively impact those living with other autoimmune disorders.

#7. Classroom Lighting Can Interfere with Your Lesson Plans

Until you know what to look for, you may not initially recognize the impact of unfiltered fluorescent or LED light on your students. Young people may be more susceptible to the effects than adults.

In addition to the headaches, sleep disruption, and the effects on moods and emotions, research also suggests that fluorescent classroom lighting can contribute to:

Light intensity and color temperature are shown to have a significant impact on student progress. The loss of visual acuity and reading difficulty is directly related to lighting glare. In classrooms where glare is minimized, classroom performance can improve by as much as 25 percent. Filtration helps students remain alert and focused.

Lighting and Student Performance

Modifying Classroom Lighting Inexpensively with Natural Light Filters

Many teachers who are concerned with the effect of lighting in their classroom are opting to filter the harsh, glaring light of their overhead fixtures with fluorescent light covers.

It is well known that students perform better when exposed to natural sunlight as an indirect light source. Natural light helps the learning environment by helping improve students mood while increasing overall performance. Studies show that test scores can improve with more focus and less eye fatigue from better lighting.

When investigating your options, it’s important to remember that not all products are equally beneficial.
