Some lights are actually bad for your health.

Have you ever wondered what environmental aspects of your office could be changed to improve your and your employee's mood and productivity? Well, the answer might be just over your head!

Some lights are bad for your health.As American office workers, we spend at least one-third of each weekday in the office - and while it is everyone's goal to have a successful and productive workday, often something as simple as lighting impedes our ability to do so. A study conducted by the American Society of Interior Design disclosed that 68 percent of employees complain about the lighting situation in their offices. This substantial number implies that many employers could be making the same mistakes.

While natural lighting is the most desirable solution, we can't all grab our desks and work outside everyday. We can, however, implement the science of the human mind's response to light to improve mood, productivity, and success.

The temperature of light, measured in Kelvin (K), is a numerical measurement of the color that's emitted when an object is heated to a high enough temperature. As the temperature increases, the object changes colors and emits certain colors of that light.

Higher color temperatures (4,600K or more) appear blue-white and are called cool or daylight colors. A typical sunny day is about 5,000K or 5,500K and is considered a cool color.

Mid-range color temperatures (3,100K–4,600K) appear cool white. A sunset is about 4,000K and is considered a cool white color.

Lower color temperatures (up to 3,000K) range from red to yellowish-white in tone and are called warm colors. The glow-from-the-fire lighting is about 2,000K and is considered a warm color. [source]
Studies show that working under "blue-enriched" light bulbs that are 17,000K increases work performance by supporting mental acuity, vitality, and alertness while reducing fatigue and daytime sleepiness.

Felderman and Keatinge, researchers at the University of Greenwich, found in a two-month study that the workers they put under "blue-enriched light bulbs" reported feeling "happier, more alert and had less eye strain."

Other benefits of blue light include lowering melatonin, which is created in our glands and puts us to sleep. This lower level of melatonin keeps people alert in the same way coffee does.

With so many brainpower benefits, blue or cooler light should be kept in brainstorming rooms where you want people to feel invigorated and excited to share their ideas, according to Felderman and Keatinge.

On the other hand, since warmer tones tend to create a sense of comfort, use this kind of lighting in more intimate settings where you want workers to feel calm and relaxed, perhaps in a meeting room where you want to emit trust.

Conference rooms should have middle tones that produce a friendly and inviting environment, but also cool enough tones to keep workers alert and motivated.

Throughout the day, light also needs to change since space acts as a working organism, according to Felderman and Keatinge. Earlier in the day, lighting in the office should be cooler and blue and should gradually change to a warmer, yellow color as the day progresses.

The most innovative companies are already discovering the power of strategic lighting.

"You're going to see, in the next six months to a year, major changes in lighting technology in companies," said Felderman. "More and more companies will have programmable lighting that will be able to be changed as one desires."

The next time you find yourself eager to get into the office in the early hours and not mind staying late after hours, it's possible that new lighting has changed your rhythm and given you a slight advantage.

What a pleasure it was dealing with Aubrey of John's electric! We had a breaker that would not reset. Aubrey arrived at our house at exactly the time he said he would. He had the problem diagnosed in under a minute and had us back to normal with all of our garage outlets in under 5 minutes. I know that all service calls can't go that quickly, but he sure found the problem right away and got it fixed immediately. I would strongly recommend this company.
