Biomechanical insights into the regulatory effect of light on residents’ emotions and physiological rhythms in human living environment
Abstract
In the field of modern biomedical science, biomechanics focuses on the mechanical properties and interactions of molecules, cells, tissues, and organs, which is crucial for a deeper understanding of how the human body perceives and adapts to changes in the external environment. As an important environmental factor, light’s impact on the human body not only involves psychological and physiological aspects, but is also closely related to biomechanical mechanisms. Therefore, this study aims to explore the regulatory effects of light on residents’ emotions and physiological rhythms from a biomechanical perspective, providing a new perspective for revealing the mysteries of the interaction between light and the human body. By measuring physiological parameters such as heart rate, respiration, and skin conductance response, investigate whether there is a certain resonance between exposure to light of different wavelengths (red, green, blue) or color temperatures (3000 K, 6000 K) and hearing. The results indicate that auditory or visual environmental stimuli can indeed cause changes in human physiological parameters and emotions; The dynamic lighting environment has a stronger impact on emotional perception; Revealed the feasibility of using physiological parameters as the basis for acousto-optic fusion perception and judgment. Understanding the relationship between color and psychology is crucial for creating a living environment that meets people’s psychological needs. Finally, summarize the principles of human living environment lighting design based on color psychology, providing guidance for future design practices. This study reveals the intrinsic relationship between light and human biomechanical response by measuring a series of biomechanical related indicators, providing scientific basis for optimizing human living environment design.
