Indoor Lighting and Effects on Emotions
Lighting levels have an impact on human performance at many points, including vision, understanding, and mood. Therefore, it cannot be ignored that lighting affects the productivity of employees in a workplace or the learning situation of students in a classroom.
Researcher Alison Jing Xu says that the effect of a bright light on our emotional structure stems from the heat perception of the light and the heat perception stimulates the emotions. According to Alisaon Jing Xu's research, lighting a room affects decision-making and bright light acts as a catalyst for more intense emotions.
Light affects human behavior such as sleep order and mindfulness in a wide range. Research has shown an increase in the performance of students working in natural daylight. Natural light is always a plus; however, it may not always be available in places such as a classroom or business environment.
Natural light should be preferred as much as possible because it affects positively the mood of employees and students.
Due to the fact that we spend most of our time indoors, the amount and quality of light during the day varies according to the work we do. Illumination can affect our overall health and happiness depending on our eye comfort. It is quite common for eye fatigue to occur due to lighting or lack of lighting. Insufficient lighting, glare, flicker etc. situations may cause this. Eye fatigue can lead to general health problems such as headache, restlessness, fatigue and feeling unhealthy.
As in many areas of life, lighting should be in an appropriate balance where people work, spend their time or rest. Achieving the desired distribution of lighting is closely related to the light source and luminaires.
Fluorescent lamps are the most suitable form of lighting for the wide distribution of public areas such as meetings and classrooms. Low-voltage incandescent light sources and LED luminaires are suitable for narrow spaces such as corridors and staircases.
To achieve the right balance, different lighting levels in industrial or academic areas or residential areas need to be assessed by business managers. It should be remembered that a low level of light can cause sleep and an extremely bright light can cause emotional arousal. Therefore, a proper balance should be considered.
