Lighting Science Group announced Tuesday that it would add warning labels to all its products, alerting consumers to the dangers of artificial light and directing them to a website where they can learn about the latest research. The labels say, “Exposure to certain electric lights may cause biological effects, some potentially disruptive.”
Many scientific reports have found that the blue spectrum light emitted from TVs, computers, smartphones and tablets, as well as from regular incandescent and compact fluorescent lights (CFLs), suppresses secretion of the hormone melatonin that helps us fall asleep. That leads to trouble sleeping, which in turn brings on a host of other issues, such as weight gain, mood disorders and increased risk of heart disease and diabetes [as well as certain cancers including prostate and breast cancer].
