Exposure To Blue Light

Indoor exposure to artificial light was determined through personal questionnaires.The researchers found the bluer the light emission that people in large cities were exposed to, the higher the risk of cancer.This was compared to populations with less exposure to blue light."We must also investigate whether night-time exposure to the blue light emitted by smartphones and tablets increases our risk of cancer," he said. Both breast and prostate cancer are hormone-related. This was compared led vapor tight fixture factory to populations with less exposure to blue light.Little is known about how environmental factors affect breast and prostate cancer. The researchers hypothesise that LED lights may disrupt the body's 24-hour cycle known as the circadian rhythm, in turn affecting hormones.

Researchers from the Barcelona Institute for Global Health (ISGlobal) and University of Exeter in the UK found that participants living in large cities with heavy exposure to blue lights at night had double the risk of prostate cancer and 1.LED lights may disrupt the body's 24-hour cycle known as the circadian rhythm, in turn affecting hormones.The study, published in the journal Environmental Health Perspectives, included medical and epidemiological data of more than 4,000 people between 20 and 85 years of age in 11 Spanish regions."Humans have evolved to need light during the day and darkness at night.end-ofTags: leds, lighting, advertising, breast cancer, prostate cancer, barcelona institute for global health (isglobal), university of exeter, uk.

Scientists have long suspected this may be the case - now our innovative findings indicate a strong link," said de Miguel.Older lighting schemes emit a glow within the 'orange' spectrum, but new modern lighting creates a bright 'blue' light emission. The study also found that people who lived in homes with darker rooms, by using window shutters for example, had lower risk than those who did not. As towns and cities replace older lighting, we're all exposed to higher levels of blue lights, which can disrupt our biological clocks," said Alejandro Sanchez de Miguel, from the University of Exeter."It is imperative that we know for sure whether this increases our risk of cancer."
