Sound and Light Waves in Healthy Environments: Architecture and the Health of People Through the Stages of Life

Abstract

Architects need the freedom to design their projects with the assurance that they will be inspiring aesthetic as well as healthy places, i.e., buildings, streets, parks, avenues, and squares that offer a complete living experience in an environment that takes into account light, sound, vibration, climate, and all those aspects that can disturb people's well-being. We know that prolonged exposure to noise can cause discomfort and sleep disorders, which affect the quality of life. This noise is not the only pollutant as there are other sound waves such as infrasound and ultrasound that are not perceptible but potentially harmful to health. Not forgetting electromagnetic waves, the light that reaches our bodies and which has regulated our lives throughout the existence of the species. The invention of electric lighting had the consequence that people spend practically all day indoors. Days are poorly illuminated, and the nights have too much light. On the other hand, the intensity of artificial light is a fraction of that of daylight and the spectral composition is also different.
