In the modern world, the average person spends a large chunk of their daily life in the comfort of indoor spaces, shaded from the sun. This might sound like a good thing, but sunlight actually plays an important role in our general health and well-being.

For starters, exposure to daylight helps regulate our circadian rhythms — the body’s built-in and natural clock that “tells” us when to sleep and wake up. Normally, the changing brightness levels of natural light as the day progresses helps our circadian rhythm regulate our body’s alertness and sleepiness, depending on the time of day. Since the invention of artificial lighting, we now have access to light at any given time. This has caused a major change in our sleep-wake cycle, affecting everything from our immune system to our cognitive functions and behavior.

Enter human centric lighting.

Human centric lighting is a holistic approach to lighting that includes all aspects of how lighting affects our well-being, productivity, and comfort in indoor environments. Human centric lighting helps us understand how we can make the most of artificial and natural lighting to enhance our performance, health, comfort, and well-being through balancing the visual, biological, and emotional effects of lighting.

The implications of human centric lighting means it has a number of useful applications across numerous sectors.


Tunable white-light features are excellent for schools. Whether it’s a kindergarten class or a university lecture hall, integrating human centric lighting into a lighting system can help students and teachers improve their alertness during class.

Optimized lighting can also help with concentration. For example, teachers may use a strong, cool white light during exams, or switch to a warmer white dimmed lighting for group discussions and break periods.


Intensive care rooms, recovery rooms, operation rooms, clinics, and other healthcare facilities are best fitted with a lighting system where doctors, nurses, and patients have different lighting conditions depending on their needs.

Different tasks require different lighting. For example, a lounge can have softer light to help staff relax. An operating room, on the other hand, need cool bright light to maximize concentration and alertness.


Incorporating human centric lighting into homes can help mitigate the effects of seasonal affective disorder (SAD), which usually strikes around winter, when the days are shorter and skies are gray, limiting exposure to sunlight. Human centric lighting can mimic natural sunlight inside living spaces, helping regulate moods and guide the sleep-wake cycles of occupants.

Office and Work

Office spaces are excellent areas to integrate human centric lighting into. When you have the right lighting setup, you can help your employees feel more energized and productive the entire day. For example, in offices with little to no windows, using LED lights that shift their brightness depending on the time of day prevents employees from feeling burned out. It also reduces problems like eyestrain, which happens when we’re exposed to bright light the entire day.

With all of these benefits and potential applications, you can’t go wrong integrating human centric lighting into your commercial establishment or workplace in Scottsdale.
