May 31, 2017

Recently, Atlantic Media's digital business news platform, Quartz, has launched a discussion of office lighting, where a colleague at the New York office has launched a vote on the internal chat tool to choose bright or soft light.


Different views of the people of the word, the discussion lasted for an hour, many people join the chat group to participate in the vote but did not finally come to a unified result.

Why is a discussion about lighting so intense?


There is no doubt that the light will stimulate the body to produce a clear physiological response. Psychiatrist Baba Pendse focuses on the effects of light on human mental health. He believes that lighting can adjust the biological cycle rhythm, resulting in sleep, alertness and performance impact.

In order to deal with the sun will secrete cortisol, serotonin and other hormones, the more intense the more the secretion of hormones, emotions, appetite and so are affected. This explains why people will be drowsy under the dim light.


In contrast, strong light, especially after the night of light is easy to help people stay awake. Even the use of light on the human body, the medical community there is a light therapy to help cancer rehabilitation, improve the quality of sleep in patients with dementia and help them to reverse the frustration.


In addition, the relationship between light and mood there is another explanation. MarkRea, director of the Rensselaer Polytechnic Institute's R & D Center, said: "If you let the workers sit in the dim light to do fine and tedious manual work, they will be bored."

So Rea believes that people's desire for light is out of the desire to master information. The brighter light means the clearer the environment, the more information is collected.


"We can read the book in a bright light, or easily see what the children are doing." Rea said that if the light is not enough, it will hinder the collection of information, people must spend more energy, mood will be worse.


On the contrary, the same light does not mean that people can get the same mood, because everyone's response to light is not the same, as everyone has their favorite diet preferences. So almost can not find a specific light to the whole office are satisfied.



In fact, the most people feel comfortable light from the sun in nature, sunlight is the most in line with the laws of nature, can naturally improve job performance and good for human health. Northwestern University of the United States has published a transboundary nerve experiment results that in the absence of windows in the office work efficiency than in the normal environment in the sun than in the office under artificial lighting is more conducive to improving mood, increase morale, reduce fatigue.

In order to test the results of this study, "Bloomberg Business" two journalists when a mouse back. They adjust their schedule to synchronize with the sun, get up early into the office. At first the two reporters will feel sleepy in the afternoon, adapted to the rest time after they said that every day after work are energetic.


Only by the building structure constraints, at present almost all office space need artificial lighting assistance, only the outside of the building can enjoy the natural light. If your station happens to be in a bright light window, do not waste it, try to adjust the rest to let the sun help you improve work efficiency.
