*7.1. Limitations of Study and Foresight*

The difficulties of this study stem from the scarcity of existing research in this field. The effects of continuously increasing or decreasing the percentage of blue light in a systemic way are unknown for human beings and, therefore, for children and adolescents. This is because, until a few years ago, it was not possible to make luminaires with alterable light components.

*There is no possibility to control the luminaires that are being made in real time for two reasons:* (1) any *company or person can buy LEDs, group them, and use a programming system with a remote control to change the proportion and composition of their light as desired* and (2) as there is no legislation on the non-visual effects of light, the proportion of blue light cannot be legally limited.

Due to these limitations, no concrete recommendations can be given to safely improve the health of adolescents. The scientific study of the effects of non-ionizing light on living beings is known as photobiology. This field does not currently exist as a separate subject, but is a new branch of knowledge that involves dermatologists, ophthalmologists, physicists, opticians, and chemists, each in their own fields. The aim of photobiologists is to integrate the specialty into all degrees of training in the health field (pharmacy, medicine, veterinary medicine, architecture, and engineering related to animal and plant biology).

Given its relevance to healthy human functioning, this content should be integrated into the curriculum from the earliest stages of education, with greater emphasis on the secondary and high school stages and the professional branches related to the field. In this sense, students should be aware of the impact of healthy ethical light in different contexts:


Therefore, the establishment of natural or artificial lighting according to natural parameters should also be a priority issue in the design and construction of new educational centers, as well as in the lighting of existing centers, to facilitate the transformation of toxic light into a new ethical–healthy model. In this sense, it is also necessary to train senior educational managers (central and autonomous community administration staff, as well as the directors or presidents of educational centers).

Additionally, this research offers a framework for study and reflection that will allow national and international governments to regulate lights in order to promote naturalization processes and new models that are applicable to the domestic, health, professional, and educational fields, thereby facilitating the incorporation of new measures and training that will make it possible to overcome the lack of existing regulations and training.
