Choose White or Warm, the right light for you is the best one!
In daily life, we are most often exposed to blue white light and warm light. It is the colour temperature that sets them apart! The colour temperature is the temperature of a black-body radiator that emits light of different colours, from red to orange to yellow to blue, when heated at different temperatures. The lower the colour temperature is, the yellower/warmer the colour becomes; when the colour temperature increases, the colour shifts from white to blue. Lighting colours will affect the secretion of melatonin. Compared to warm light, white light contains more of the blue spectrum. In white light, we stay more alert, as it inhibits secretion of melatonin. On the other hand, warm light has little effect on the secretion of melatonin. That’s why we feel more relaxed in warm light. We should choose proper lighting to suit individual working requirements. At work, white light of a high colour temperature helps you stay focused, while warm light of a low colour temperature (<3000K) is better when you need some relaxed reading time, as it rarely affects the secretion of melatonin, allowing you to relax and decrease your alertness before going to bed in order to have quality sleep and get ready for the next wonderful morning.
The majority of people nowadays spend 90% of their time indoors. Interior lighting has thus become more important for the current generation. Unlike outdoor environments, which present various colour temperatures, indoor environments are often conditioned by a fixed lighting source with a fixed colour temperature. The lighting affects our circadian rhythms, as well as our sleep quality and health.
