What connection is there between the two?A recent article posted in Cancer Weekly highlighted the issue of artificial lighting and how it can affect your sleep cycle and damage your overall health. When you're ready to go to bed, your cortisol level drops, your melatonin levels rise and you fall into several sleep cycles throughout the night.University of Connecticut cancer epidemiologist, Richard Stevens, has been studying this theory for many years and says, "It's become clear that typical lighting is affecting our physiology, but lighting can be improved. We're learning that better lighting can reduce these physiological effects. By that, we mean dimmer and longer wavelengths in the evening, and avoiding the bright blue of e-readers, tablets and smart phones."The problem is now as a society, we're more connected than ever and now have access to everything online, which allows you to bring laptops, smartphones, tablets, iPads and TVs in your bedroom... all of which increase stimulation, cause disruptions in your sleep cycle and cause other health issues..including cancer.
