Say it a boon or curse, but due to the modern lifestyle, our indoor stay time has increased rapidly. As we spend 90% of our time indoors, we do not consume the adequate amount of sunlight which is paramount for the human body. The indoor light conditions do not deliver light nutrition that people need to stay healthy. A sunny outdoor day provides 100,000 lux and a cloudy day still provides 10,000 lux. Indoor light levels are not even half of that. This artificial light that we have in our indoor environment (offices, homes, etc.) can throw off our eternal clocks and cause issues with sleep. It can further lead to destructive health consequence i.e. poor circadian synchronization, problems with body clock similar to jet-lag, disturbance of hormonal system, and compromised mood and productivity. This lack of exposure to the sun’s spectrum disturbs the Human Circadian System which is fundamental to our physiology and controls much of our behaviour.
“This diagram depicts the typical circadian pattern of a person. Although circadian rhythms tend to be synchronized with cycles of light and dark, other factors such as ambient temperature, lack of sunlight, stress, etc. can influence the rhythm as well.”
The natural variations of sunlight help determine the timing of our internal clock called the circadian rhythm and tell our bodies when to sleep and when to be alert. If our sleep-wake cycle is deregulated, it can affect our immune system, memory, and behaviour. Our health is somewhere suffering in this disconnection between natural light and artificial light. Though we cannot cut short our indoor stay time, but by replacing the conventional lighting solutions with human-centric lighting we can surely make a big difference.
Benefits of Human Centric Lighting
Light affects our vision, body, and emotions. Human Centric Lighting enhances human performance, comfort, health, and well-being by balancing visual, emotional, and biological benefits of lighting for humans. It also improves alertness and concentration during learning by providing a better light environment. Lighting systems that give higher light intensities and colour temperature at the right time can help to improve the duration of sleep and quality of sleep and thus improve learning effects.
- Maximizes the concentration and energy.
- Improves work performance and productivity.
- Increases employee motivation and commitment.
- Assures health safety in the indoor environment.
- Improves circadian rhythm and quality of sleep.
- Biorhythm adjustments for night shift workers.
- Increases emotional stability and lowers the rate of depression.
Human Centric Lighting should be implemented across various sectors to ensure the well-being and performance of people at a maximum rate.
Schools are an excellent location for tuneable white light features. It doesn’t matter if the person is an elementary scholar or a teacher, both can leverage the benefit from an optimized lighting environment in a direct or indirect way. Human Centric Lighting can be used to improve alertness during tests and concentration tasks. The teacher may switch on an intensive, cool white light during these activities, or a warm white dimmed light for relaxation and group talk.
Healthcare environments (operation rooms, recovery rooms, intensive care rooms, etc.) are well suited to implement Human Centric Lighting. To improve the conditions for patients, nurses, and surgeons, HCL should be implemented because it dives the room in different lighting zones depending on the tasks. This results in less strain on the eyes, less fatigue, and improved quality.
Incorporating HCL in residential areas can prevent mood fluctuations, depressions, and stabilizes the circadian rhythm. The emotional and physical well-being can be improved because of restful nights in better environments. The residents can feel more relaxed with fewer headaches and less tired eyes.
Corporate areas are excellent places to implement Human Centric Lighting as it can bring energy and motivation to employees. For countries with little daylight, HCL solutions may reduce seasonal depressions and other emotional disorders. Workplace lighting, in addition to providing enough light to conduct work-related visual tasks, can also improve employees’ alertness, mood, cognition, sleep-wake pattern, and health.
It is important to understand how light can impact the occupants’ health, productivity, and overall potential. With the range of modern lights options available (LEDs, tuneable white lights, etc.), establishing a safe and healthy space is easier than ever. They are also energy-efficient and easy to control with advanced control systems. Human Centric Lighting promotes smart and connected lighting systems that can create endless possibilities with better user control.
