Circadian rhythm is a sort of an internal clock that responds to lighting and signals one's body and brain when it's time to wake up and go to sleep. It controls our energy level, mood and sense of alertness or sleepiness. Our brain regulates the circadian rhythm of the body based on light signals from our environment

Designing an office space is not just about aesthetics, colouring and illumination but it is much more than that. An ideal workspace should enhance employee productivity and reduce stress level and strike an ideal balance between privacy and collaborative working.

Several studies have shown that access to natural light increases alertness. There are recorded instances where installation of human-centric lighting has boosted efficiency by 15-20%. There’s a reason people tend to be happier when it’s bright and sunny rather than dreary and gray. If your office is a dull place with limited natural light, your employees might be snoozing by lunchtime. Using natural light to illuminate an office space has many benefits. Apart from being eco-friendly and able to lift moods, it helps employees maintain natural circadian rhythms.

Studies have revealed that office lighting can impact employees circadian rhythm and change their overall productivity, mood and health. Circadian rhythm is a sort of an internal clock that responds to lighting and signals one’s body and brain when it’s time to wake up and go to sleep. In other words, the circadian rhythm controls our energy level, mood and sense of alertness or sleepiness. Our brain regulates the circadian rhythm of the body based on light signals from our environment. When our inner clock no longer functions synchronously with the time of the day we become agitated and our reactions slow down we are less attentive and it becomes more difficult to concentrate.

As people spend more time indoors and less time outdoors, they have less exposure to the natural rhythms of daylight. Of the time spent indoors, half the time is spent in offices. Therefore, it is necessary to take advantage of the technological evolution and to mimic the effects of natural light in an office, helping to optimize people’s circadian rhythms and improve mood and productivity.

Office lighting is an important aspect of interior design as eye strain, exhaustion, and weakening mental health are all issues that share a root cause in poor access to light.  Just like with a healthy diet, if we feed the body what it needs, it will perform better.
