Natural Light and Mental Health: Inspiration for Lighting Technology

Your mental health is of prime importance to lead a wholesome life! Every now and again, we’re all told to step out in the sun to boost our well-being. And, why not? Various studies have proven that sunlight has a profound impact on your mental and physical health. There have been studies which show that more cases of depression were recorded during winter when the days were shorter as compared to summer. Why? Exposure to sunlight triggers the release of serotonin in our body, which contributes to our well-being. Such is the beauty of science!

Thus, it is evident that an introduction of natural light in your daily life can influence your state of mind. But, more often than not, your work schedule won’t allow you to take a break and venture outdoors. Keeping this in mind, the lighting experts have taken up the responsibility of promoting good mental health and improving efficiency across work-spaces. To bring natural light therapy right to your cubicle, innovative lighting solutions are being developed.

Human centric lighting: Artificial lighting for natural effect

Technology has been upgraded to such a level that, it focuses not only on lighting up an area, but also suiting your health. Quite an improvement, right?

Human centric lighting is designed in such a way that it matches your biological clock. The Earth’s natural lighting cycle has made our body to respond according to the varying intensities of light. Daylight triggers the production of dopamine and serotonin which aid in alertness and concentration. Moonlight releases melatonin which indicates your body to relax. If your body is not exposed to such different intensity of lighting, this rhythm, termed as circadian rhythm, will be disrupted, affecting your health. To avoid such fatal scenarios, circadian lighting has been brought into the picture as it mimics the patterns of daylight to match your internal clock. Human centric lighting also helps to uplift people’s moods and improve visibility. Adjusting indoor lighting according to the human clock can shoot up productivity levels among employees. If you are wondering how circadian lighting works in the favour of your health, here you go!

Circadian Lighting:

According to research, retinal ganglion cells, which are responsible for setting up our internal clock, are found to be responsive to blue light. Circadian lighting implements this finding and introduces light with a blue wavelength during daytime. This significantly improves concentration, thereby resulting into increased productivity. LEDs also enable you to adjust colour and temperature, which makes them the optimum solution for circadian lighting.

To tune the intensity of light indoors, correlated colour temperatures can be adjusted as the day progresses. Your day starts with a lower intensity, higher intensity during the noon, and reduced intensity in the evening, similar to natural light pattern. Cooler temperatures are maintained to induce alertness at work-spaces. What does it result in? Higher productivity and reduced hyperactivity are the documented results of circadian lighting. Not disrupting your natural cycle gives way to a significant improvement in your overall health and work efficiency!

We, at Havells, promote human centric lighting so that you can continue to work indoors without missing the magic of natural elements. Lighting technology has come a long way and it will flourish further with newer technologies that make your life better. Lighting up your space not at the cost of your health is where the lighting industry is headed!
