Blue Light is mostly friendly, we say ‘mostly friendly’ as it has not been around long enough for centuries of research and we are only now noticing its somewhat of an indirect, silent assassin. It can affect your sleep and this can potentially flow on to cause diseases. Until the invention of man-made lighting, the sun was the major source of light, and people spent their afternoons in almost darkness. Now, in much of the world, afternoons are as bright as day, you can thank Thomas Edison for inventing the light bulb.
Blue Light – The Silent Assassin
But, is all this light a double-edged sword? Is the human eyes, brain and body built for 14-16 hours of light? In the afternoon light alters the body’s biological clock otherwise known as the circadian rhythm, the effect is difficulty sleeping or poor sleep. We are slowly identifying through research that blue light may contribute to the causation of cancer, diabetes, heart disease, obesity and that’s not all. Poor sleep and blue light have been linked to moods, productivity, ability to handle life’s simple problems and there is a strong link to poor sleep and depression.
