Light: the main source of light for all living organisms. It’s what gives life to plants through photosynthesis to feed us and provide oxygen, stimulates vitamin D production in our bodies, as well as regulates our sleep cycle! Humans lived with solely natural light until 1879 when Thomas Edison invented the light bulb. Since our industrial revolution, much has changed. In fact, people now spend 91% of their time indoors, that is, AWAY from sunlight. With this significant increase indoors under artificial lighting, there have been some observed detrimental health effects. The first of which includes that 61% of people now have/wear some type of correction in/on their eyes. Artificial light, especially blue light, causes our eyes to strain and eventually damage our retina . Additionally, artificial light’s low quality spectral patterns does not reach our visual cortex to perceive images. The retina is in constant communication with our brain, so when that becomes damaged, our focus is also lost, hence less productivity. In fact, there have been studies in grade school classrooms where the school has put environmentally improved light bulbs in the classroom and the productivity increased! Unfortunately, with so many schools and businesses on a tight budget, improved light bulbs are not a priority on the list. The best we can do is at least have better light in our homes! Natural light also improves mood, hence the reason people use light therapy to combat seasonal depression during low sunlight times. The low quality light we receive indoors may just be one of the many environmental causes for increased mental health disorder and special needs cases today.
