Ever wonder why you feel a certain way at a certain time? It is due to our Circadian Rhythm, which is the biological process that most living things follow in regards to how an organism functions in a 24-hour time frame. It is important for our bodies that we do not see a disruption in this rhythm. When a disruption occurs, the overall success of our immune system and well-being is negatively affected.
Among other things such as ambient temperature, light is one of the main drivers behind our Circadian Rhythm. By detecting the temperature of light(temperature refers to what we perceive as the color of the light, a higher temperature is a bluer light, lower temperature is more yellow light) in our environment, our bodies are able to prepare for certain events through the day. One of the most important events for our bodies is when it’s time to sleep, by detecting a shift in the temperature of light to a lower(or more yellow) shade we start to secrete melatonin which aids in rest, allowing us to recover from the day’s events. On the flip side, when the temperature of light starts to increase to a “daylight” color in the morning we stop secreting melatonin and begin to secrete testosterone which increases energy and activity, helping us to get up and get ready for the day to come.
Currently there is a trend in the LED lighting market towards providing lights that are able to change temperatures by remote. This technology is still in the early stages of development but we are excited to see this functionality as it will increase our ability to adapt to specific circadian needs in the most cost effective way.
By utilizing this knowledge in lighting applications we can create the most productive atmosphere possible. By using higher color temperatures in areas of activity, such as a school/office or lower temperatures in areas of relaxation we can maximize the effectiveness of individual environments to help get the most beneficial results possible.
