This time, I'm going to talk about how the lighting in your room can change your attention span.What color is the lighting in your room?
From a psychological standpoint, the meaning of color is often used to manipulate impressions, but there are also studies that show that it can change a person's ability to concentrate and pay attention.
If you are in a room or workplace where you want to concentrate, why don't you refer to the results of the following research?
The study
This study was looking at whether certain types of lighting can change the alertness levels and mood states of workers during the day.
This is said because light has been implicated in many biological functions and is thought to affect sleep, mood, and wakefulness.For people who spend most of their day indoors, it has even been suggested that illumination levels can lead to reduced alertness and mood disorders.
This study will analyze the effects of all types of lighting on the attention and mood of workers who work indoors.
The lighting included cold white light compared to warm light, different levels of light intensity, and exposure to sunlight.
The five studies involved 282 participants.
The participants were clerical and hospital office workers.
Two studies examined the effects of cold white light, and one study focused on indirect light sources.
Another two studies used special glass or light boxes (flat boxes with translucent glass or plastic sides that contain light) to shine the light individually and examine the effects.
The results.
Cool white light was found to improve alertness, but not mood.
The results also suggested that this color may reduce irritability, eye discomfort, and headaches.Changing the ratio of direct to indirect light in the workplace does not seem to have much of an effect on alertness or mood.
We also found that using LED-equipped glasses to produce a bluish light resulted in improved agility and mood.
In addition, when people showed symptoms of mild, early seasonal depression, there were results of improved arousal and mood when exposed to the light individually.
Reviewer's Comments.
Additional research is still needed because all findings are based on low or very low quality evidence (due to the small number of studies and participants, as well as problems in how the studies were conducted).

Summary
The results of the study were not able to say that light increases performance.
As for the illuminance, I have heard that there is a standard value in the building standard, and I have heard that the standard value is set based on the effect on the human body.Since the exact unit of illuminance was not mentioned in this study, it may be desirable to use a white light source for color.
