Is blue light bad for us?
An engineer's opinion
For the past few years, we have been hearing about the effects of blue light, this type of lighting is generated by LEDs and also by our smart devices. A handful of scientists have called for protection from this lighting and the optometry community has even thought about special glasses. Yet, is blue light really bad for us?
A physicist and researcher at the French Society for Radiation Protection sought to answer this question in a podcast called "Digital World." While it's true that the glow can have an effect on circadian rhythm and sleepiness, photochemical risks are virtually nonexistent. In fact, it would require a much longer exposure and by devices diffusing it intensely.
Or, our phones meet standards well below the permitted limits. Especially since the researcher has tried these blue light protections and they are only marginally effective against an already not dangerous source.
The physicist reminds us that the sun poses far more risk to the retina than LEDs. Consequently, it's all very well to go outside, but on very sunny days, it's best to wear your UV protective glasses.
When an administration leaves control of the environment and execution to those whose competence it has recognized, the school adjusts and the teachers become involved.
Taking the logic a step further, once students are recognized as competent to study, why take away their control of their study environment, which includes both their organization and how they go about it? Why can't they choose online courses in high school?
When we reread the documented experience of a Cree/Eeyou tracker, a native of North America, we understand that interpreting also involves the body and symbiosis with the environment.
Bullying is nothing new. Unfortunately, it has always occurred in all social environments, and particularly in schools. Today, however, it's making more headlines because we're increasingly aware of its deleterious effects on children. All the more so as the phenomenon has become more pronounced in the virtual world.
Trace, history, the past: 3 interrelated but distinct notions. The memory of all and the ecosystem of the thinker will make interpretations go right or left, adding another layer to the general story.
The solicitation of its senses allows the child to develop, to integrate the fictional universe and especially, to learn to control its environment. All the senses are called upon when one is in contact with a comic book. Awakening the senses through the story is a primary stage of development, but stimulating the imagination is an even higher level.
