Blue Light Waves at Night

Some believe that the photoreceptor cells in the retina display the highest rate of oxidation of all cells in the body. Apparently, unprotected exposure is bad enough during daylight hours—worse at night. Researchers have linked exposure to artificial blue wave light at night (e.g., working the night shift) to an increased risk for diabetes, heart disease, obesity, some types of cancer, diabetes, heart disease, and an increased risk for depression. This may be because blue light waves can suppress the production of melatonin. Lowered levels of melatonin are linked with inadequate amounts of sleep; inadequate amounts of sleep are linked with the development of chronic illnesses; chronic illnesses are linked with a potentially shortened lifespan. It’s a vicious circle.
