Sunlight has an important role in human evolution, but it is estimated that, nowadays, people spend more than 90% of their time indoors. These lifestyle changes are associated with population diseases such as sleep deficiency, myopia, or diabetes.
The sunlight pattern adjusts and balances the circadian rhythm, our internal clock controls our metabolism, so when it stops functioning correctly we can have some problems in our metabolism.
When we have a disruption in our circadian rhythms such as working or traveling, our bodies are affected and we may have some sleep disturbances. Thus, if we don’t have a good rest, we do not allow our body to heal itself. This can make us hungrier, weaker, or less focused.
Depending on the type of light we receive our body has a different response, that is:
- Bright white light in the morning gets us ready for our daily activities, so our body starts producing the daytime hormones such as cortisol, serotonin, GABA, and dopamine, which modifies the synthesis of follicle-stimulating hormone, gastrin-releasing peptide, and TSH [1].
- Warmer light and darker conditions help us relax and sleep and recover for the next day, so our body starts to produce the night-time hormones such as melatonin, vaso-intestinal peptide, and growth hormone [1].
Human-centric lighting is a way of reproducing the natural cycle of daylight indoors, which can have a positive effect on people’s circadian rhythms. Thanks to advances in control lighting, we can design lighting systems that adapt to the movement, intensity, and color of sunlight, improving sleep quality.
KUMUX offers the HCL lighting solution which is 100% adjustable in brightness and mimics the rhythm of natural light providing the right light at the right time for the right space and the right activity improving people’s sleep.
