Many of us may not know that our lighting environment has a tremendous effect on our overall well-being and lifestyle, as is evident from scientific research and studies in the past. A perfect interior setting of any house is always complemented by perfect lighting, and there are various facts and terms around lighting that every common man needs to be aware of. While good lighting can truly define and drive one’s emotions and moods, long-term exposure to inaccurately designed artificial lighting on the other hand can adversely impact our mood, eyesight, sleep patterns, and other aspects of health.
It is important to note that when we talk about good lighting, it denotes both the quality and quantity of lighting inside and outside our house. The amount of light of a space is usually measured in LUX. It is important to have just the right amount of light to read at your preferred locations, to find your favourite jewellery (if you drop it around your dressing table), to be able to see minute objects, to do specific tasks and avoid stumble while moving in the house, and so on.
Sure enough, the lighting levels will vary throughout the house depending upon the functionality. While insufficient light means we strain to see, overwhelming light will blind our vision. Therefore, it can be concluded that “too much” or “too less” of lights are not what we should ideally opt for.
Further, how well one can distinguish colours using the light is measured as CRI or Colour Rendering Index. This one is really important to:
- see a green worm while you are cooking ladyfinger
- react to the pale skin of your child which indicates they are unwell
- distinguish between navy-blue and black shirt
Thus, we clearly see it is important to make sure you take conscious decisions pertaining to lighting colour index for a healthy quality of life.
It is advisable to make maximum use of daylight/whiter lights in the kitchen and study table of our homes as this would keep you attentive and productive. White light or blue light suppresses melatonin hormone level which leads to sleep difficulty and keeps you more attentive.
At the same time, warmer lights should be in the bedrooms, drawings rooms and dining spaces which to make us feel relaxed and help us get to sleep easily. We can definitely use coloured lights for enhancing our mood and celebration, but it is important to remember that our eyes are not great at doing tasks in coloured lighting. The right approach is to have a combination of warmer coloured and cooler coloured lighting fixtures at our homes.
Lastly, we have a new parameter on the block which directly affects our health—flicker. This was not so prevalent in earlier lighting sources but with the growing popularity of LEDs, it is a menace now as most of Indian consumer products have flicker. We cannot see flicker with naked eyes but if present in your light sources, it will definitely harm your eyes and health. Thus, flicker and glare-free products are highly recommended.
