Invisible Enemies Surround the Classroom to Affect Teachers and Students' Health

Poor air quality, germs, and blue-light from LCD panels, are the silent enemy of a healthy classroom environment. When risks like these are prevalent, it can be detrimental to learning efficiency and school absenteeism. Due to COVID-19, maintaining a hygienic and collaborative classroom, without impacting educational outcomes, is now a top priority. Let’s look deeper into how germs, poor indoor air quality, and screen lights, affect the learning environment.

Did you know that germs are commonly accumulated
on the following items in school ?

Student's hands

Sink faucet handles

Keyboards

Bathroom door handles

Cafeteria tables and trays

Germs contribute to school absenteeism

In today’s learning environment, students are writing on interactive displays with their fingers, doing group activities together, and solving the problems side by side on the same display. A recent article in The Active Times highlights how germs accumulate and spread, on items such as：

students hands

sink faucet handles

classroom computer keyboards and desks

bathroom door handles

cafeteria tables and trays

Respiratory (colds and flu) and gastrointestinal illness (Norovirus and Rotavirus) are easily transmitted by touch, and a significant cause of school absenteeism. On average, in the US, each student is absent for 4.1 days, and the average teacher misses 5.3 days per school year per academic year. This amounts to losses of 10.7 billion per annum . Therefore, providing an interactive, yet hygienic, learning environment is crucial.

Poor indoor air quality affects student concentration

According to a study by The U.S. Environmental Protection Agency (EPA), indoor levels of pollutants may be more than 100 times higher than outdoor levels. In particular, CO2 ventilation rates in schools are inadequate. A CO2 buildup in classrooms can lead to discomfort and subsequently to learning difficulties and loss of concentration. Furthermore, poor indoor air quality can cause coughing, eye irritation, allergies, asthma and headache. Teachers need to be aware of the classrooms current environmental parameters in order to take remedial action.

Cough

Eye imitation

Allergic reactions

Asthma

Headache

Vision impairment causes poorer learning outcomes

According to WHO statistics, at least 2.2 billion people worldwide have a vision impairment. Many eye problems start at a young age, and may be due to constant exposure to the blue lights and flickers associated with electronic screens. Blue light is a powerful visible light which includes blue, indigo and violet light. The short-waves of violet light (UV) can penetrate through the cornea and lens, directly into the macula, causing damage to its photoreceptor cells.

Generally, screen flickering is not visible to the naked eye, occurring up to 250 times per second. During a regular 8 hour (working) day of screen viewing time, flickering occurs some 5,760,00 times. With the increasing adaptation of digital technology in classrooms, digital eye strain, also known as Computer Vision Syndrome (CVS), has become a major risk to students’ eye health.

Germ-resistant screen eliminates 99% of germs and bacteria
