● Regarding the impact of light on human health, the public has not yet formed a comprehensive and scientific understanding.

1 healthy office light environment to meet three parts

I have been doing research in the field of the office environment for many years. The concept of health is very early, but I think it is the WELL standard to quantify it for the first time. It is reflected in a language that light designers and architects can understand. Come out. I personally believe that a healthy office light environment must meet the requirements of the following three parts.

The first one is to reduce the negative impact of the office environment on human circadian rhythms. If we are outdoors, eating fruits and hunting like primitive people, the circadian rhythm is the most natural, but modern people’s lifestyle changes, circadian rhythms It is bound to be influenced by the indoor environment of modern living, so what we can do is to reduce the negative impact as much as possible.

The second important part of the office light environment is how to make office lighting help to improve employee productivity. In fact, solving this issue is a win-win situation for employees and employers. Every owner wants employees to work more efficiently. If you can improve the productivity of office workers through the office light environment, owners may have a higher enthusiasm to design and install healthier lighting systems.

The third part is a comfort. To create a work environment with high visual comfort, it is closely related to the color temperature and illumination of the light source used in the office. According to the current illumination standard, the office lighting will usually choose a color temperature of about 4000K. But there are also new academic studies on visual physiology and psychology that do not have this inevitable relationship between color temperature and visual comfort.

2 The effect of light on human health is actually more profound

In China, everyone understands the impact of air pollution on human health, but the impact of light on people is far more profound. It affects people’s circadian rhythms, sleep, and hormone secretion. Much medical research has obtained relevant results.

For example, when you wake up in the morning, the light needs to be brighter. This will improve the alertness of the person and may help improve the work efficiency of the person. However, in the evening, if you are still very bright, very white and blue, It will inhibit the secretion of melatonin, which will affect people’s sleep. At night, in terms of spectrum and color temperature, the warmer yellowish color temperature is more suitable for sleep.

3 Lighting is vital in the office environment

If an office air conditioner is broken, people can stay in it for at least half an hour or even an hour, but if the lights are broken, many offices with poor natural lighting will not be able to continue working. People have a relatively high tolerance for poor lighting, but many people don’t realize that the human body has a high demand for good lighting. In addition to health, it will have the overall atmosphere, comfort, and functionality of the office environment. Have a great impact.

4 The health industry is one of the fastest growing industries in the world

The health industry is one of the fastest growing industries in China and the world. But the public did not realize the impact of light on people’s health, or there was some inaccurate information that was rumored by everyone.

For example, everyone always said that blue light damages the eyes, but from the 450-500 nm wavelength, all of the blue light, only a small part of the eyes of teenagers may be harmed by long-term exposure, while other spectral blue light, in the current study Underneath, there is no such negative impact.

A correct understanding of the impact of the light environment on human health will help people to more scientifically using the science and health principles of light in their living and working environments. I feel that spreading rigorous and scientifically validated information to the masses is a great advantage and responsibility of the Yunzhiguang platform.
