Maximise wellness and productivity with good lighting

Prag Bhatnagar, senior vice president, Havells India, highlights four lighting strategies that can improve the work environment

Lighting does not just illuminate a space but also plays a key role in changing our moods and emotions. For instance, you must have noticed that bright lights inside a shopping complex cheer you up while inadequate or flickering light inside a subway makes you feel anxious and unsettled. According to a study published in the Journal of Consumer Psychology, the brighter and more intense the light, the more heightened are our emotions, good and bad alike. Therefore, selecting proper lighting is a critical aspect while remodelling or designing an office.

Bring in natural lighting

Natural lighting helps boost productivity and biologically stimulates the production of Vitamin D, which is crucial for physical and mental alertness. According to a study done by Prof. Alan Hedge at Cornell University, workers in day-lit spaces reported an 84% decrease in issues like eye strain, headaches, and blurred vision, which affects productivity. In case the required natural lighting is not available, advanced artificial daylight systems can be deployed indoors that reproduce a natural scene with sky, clouds, and sunshine indoors. These lighting solutions use the latest technologies to give the feeling of daylight indoors that can liven up the ambience of a workplace.

Use indirect lighting

As opposed to direct lighting which uses a direct lamp or fixture to illuminate an area, indirect lighting is used to illuminate a wider area without causing direct glare to the employees. Since employees are already in touch with the light from various types of devices such as laptops and mobile phones etc., it is best to use indirect lighting at workplaces that illuminate a wider area with soft light. Indirect light creates a pleasant even light, without any stark contrast between lights and shadows. Reduced glare helps in lower stress levels and improve focus, thus resulting in better productivity.

Use neutral hues
Light reflects on the colours of the walls. Bright fluorescent paints on the walls will lead to a high amount of light reflection which will be harsh and fall directly on the employees and their computer systems eventually hindering work efficiency and mood. Bright colours add to a higher rate of reflection and higher lux levels at the working area. Go for softer shades by choosing paints that will help tone down the reflection from light.

Choose human-centric lighting

Innovation in lighting has led to the advent of human-centric lighting i.e. lighting that supports human well-being and performance through a focus on both visual and non-visual impact of lighting. HCL functions in a way that lighting and our body’s circadian rhythm are in harmony with each other. It works by integrating light fixtures with daylight and are designed to mimic the natural patterns of the Sun with the help of tuneable technology and automatic adjustment of intensity. It helps people perform at optimum levels. Not just the workplace, HCL is also relevant for homes, schools, hospitals, factories etc.

Good lighting can improve the overall well-being and productivity of the employees. As the saying goes, better light leads to a better life!
