Energy Efficiency and Good Health
Time and time again, studies (such as this piece published by the American Journal of Clinical Nutrition in 2004) have shown that exposure to natural light affects your vitamin D and immune system, serotonin and melatonin levels, as well as your circadian rhythms, sleep cycle and hormones. In fact, scientists at the UNC School of Medicine recently published a study in which they pinpointed the key connection between light signals and circadian rhythms. The study is anticipated to give insight on how light influences molecular signals in our bodies to affect a broad array of biological processes ranging from the sleep-wake cycle to cancer growth and development.
In addition to the aforementioned studies, the lack of proper lighting can lead to issues such as depression (S.A.D.), immune problems, and your susceptibility to life-threatening diseases such as diabetes, multiple sclerosis and cancer are exacerbated – particularly as related to Vitamin D absorption. Researchers from the Moores Cancer Center at the University of California, San Diego have found that 600,000 cases of breast and colorectal cancers could be prevented each year worldwide, if vitamin D3 levels were increased.
Only within the last couple years have we seen the building industry begin to embrace green lighting that’s not only cost and energy-efficient, but also concerned with issues related to human health. However, with heightened awareness, today’s consumers are increasingly able to tailor various lighting options to meet their individual needs.
