Light affects the performance of workers

Nowadays, if you want to be more productive and efficient for your employees, do you have to spend more time at offices, factories and factories to work?

This is not necessarily true, there are many other ways that businesses can apply to support the ability and productivity of employees, without increasing the working time, to help them produce Better products, better service and, of course, increase the profitability of your business.

One of the factors that has a direct impact on people doing it is light, which directly touches people in almost the entire working time.

Stanley Felderman & Nancy Keatinge, a couple running a Design Studio called Felderman Keatinge & Associates, said: 'Lighting has a huge impact on our physical and mental activities . ' The couple believes that our DNA works better under special light, and that's why we react differently depending on the light environment.

Learn the basics of light color temperature

Before you want to understand how light affects your productivity. We need to learn about the basic knowledge of light including the color temperature of light?

The light color temperature now measured in Kelven (K), is a measure of the color that appears with the corresponding temperature. When the temperature changes, the light will change the light color corresponding to that temperature.

For example, when a blacksmith makes a horseshoe. When the temperature rises, the horseshoe will start emitting light of different colors from red, orange, yellow, white and eventually it will emit bluish white.Lower color temperature light sources are called warm colors, and light sources with higher temperatures are called cold colors.

Cold light makes workers more productive.

Below is a summary of the color temperature of the light source:

• A higher color temperature (4,600K or more) appears in blue-white color called cold color or daylight color.
• The average color temperature (3,100K - 4,600K) appears cold white.
• Lower color temperature (3,000K return) fluctuates in tones from red to yellow, and is a hot color.

An easier-to-understand example:

• The light color temperature emitted from the fire is about 2,000K (Hot light).
• The sunset color temperature is about 4,000K (Cold light).
• Sunlight color temperature 5,000K - 5,500K (Cold light).
• The color temperature of winter days is about 7,000K (Cold light).

The link between light and productivity

What are the benefits of experts and light scientists in the workplace?

Cold light makes workers more productive. There are many studies that have shown that sunlight has innumerable benefits to our health. Exposure to natural light is extremely beneficial for workers who must confine themselves to a room all day. If using natural light for both morning and evening can reduce depression and improve mood, energy, alertness and productivity at work.

After discovering this Felderman and Keatinge replaced the entire plaster wall in his design office. With this change light can disperse throughout office space.

Lighting design for the workplace

Researchers have found that if working under light bulbs with a lot of blue light, the color temperature of about 17,000KK actually increases the efficiency of work by supporting eyesight, increasing vitality and alertness. tired and sleepy during the day. Researchers at the University of Greenwich had a study that lasted for about 2 months and statistical data showed that workers working under light-rich bulbs felt happier, more alert and less tired.

Another benefit is that working under blue light reduces melatonin, a hormone that makes us fall asleep. Keeping melatonin low helps people work more alertly than using a cup of coffee.

In addition to the blue light, or the cold light can be used in the space to think much, it helps people feel more enthusiastic and motivated to share their ideas.

On the other hand, the kind of light with warmer tones tends to create a sense of comfort. So we can use them in more intimate environments, where you want employees to feel calm and relaxed, maybe in a meeting room where trust is needed.

Other rooms such as conference rooms should have a medium color temperature to create a welcoming, friendly environment, but the color must also be cold enough to keep people happy and active.

According to Felderman and Keatinge, light should be changed throughout the day. At the beginning of the day, there should be a lot of green light and change gradually during the day.
