Emotional Response to Different Lighting Conditions

Daylight and artificial light have a considerable and significant impact on humans daily. Daylight provides natural light, which saves energy and benefits the environment. However, daylight can cause harsh glares. Harsh glares come directly from the sun and reflect on surfaces, making the environment difficult to work in. Thus, the harsh response of daylight adds to the importance of artificial lights, making them more important to have once daylight is too harsh or nighttime intervenes. Artificial lights provide individuals with many different types of light. The spectrum chart provides a broad selection of colored lights. Colored lights can have a significant impact on individuals’ emotions. This chapter discusses the impact of lights on individuals’ emotions. The effects of artificial lighting on human physiological and psychological reactions are examined in this chapter with a focus on how human eyes adjust to light, age-related changes in light sensitivity, comfort levels as determined by a visual lighting spectrum chart, and the body’s reaction to artificial lighting. Additionally, the study explores the relationship between memory performance and LED illuminance, color temperature, and melatonin suppression. The chapter also examines how artificial light affects mood, considering a person’s cultural background, the weather, and how these factors affect light. Finally, it explores how different light hues are seen by people and how that affects perception. The chapter offers insights into how artificial lighting affects people and emphasizes the significance of lighting design and choice for the best human functioning through a study of numerous studies.
