The blue light coming from smartphones, tablets and street lights can help cause cancer.
People exposed to high levels of blue at night have twice as much prostate cancer risk as one-and-a-half times the risk
It is already believed that the light emanating from electronic devices interrupts our body watches, while people who burn Use Kindles, take longer to fall asleep.
It may also have effects on hormones that can lead to cancer, according to the findings of blue light, which also emanates from LED street lights in our homes.
Researchers from the Barcelona Institute for Global Health have found that people exposed to blue exterior and interior light increase their cancer risk, based on a study of more than 4,000 people in 1
People who are exposed to high levels of blue light at night have twice as much prostate cancer risk and One and a half times more breast cancer than an international study by the University of Exeter revealed
Dr. Alejandro Sánchez De Miguel, a co-author of the study from the University of Exeter, said: "People have evolved to need light during the day and darkness at night. As cities replace the older lighting, we are all higher" exposed to blue "lights that can disrupt our biological clocks."
& # 39; We need to know if this increases our risk of cancer Scientists have long suspected that this might be the case – now our innovative insights show a strong connection . "
He added," We also need to investigate whether nighttime exposure to blue light from smartphones and tablets increases our risk of cancer
Blue light has long been seen as the cause of night shift workers having long periods of artificial light have a higher risk of developing cancer.
The light that has one of the shortest wavelengths cuts that Production of melatonin in the body, which plays a key role in the regulation of body time.
This may interfere with other hormones, and both prostate and breast cancers are hormonal
and are used by flat panel displays, smart phones and tablets, blue light comes from street lights with LED bulbs that are on the rise in the UK Kent County Council in the conversion of its 118,000 lamps.
Researchers measured exterior lighting in Barcelona and Madrid with images from the International Space Station that has measured three visible light bands – blue, red and green.
People who were exposed to blue light from street lights at night were at greater risk for breast and prostate cancer.
Indoor light was recorded, asking people if they slept in total darkness, in an almost dark room, in dim light or "fairly lit".
Blue light has long been suspected to be a night shift worker exposed to artificial light for a long time have a higher risk of cancer
While breast cancer had no effect, men who slept in well-lit bedrooms had a higher prostate cancer risk than men (19659002). Manolis Kogevinas, study coordinator of the Barcelona Institute for Global, said: "The World Health Organization's International Agency for Research on Cancer (IARC) has classified night shift work as a likely carcinogen for humans.  There is evidence of a link between man-made Light irradiation at night, disruption of the circadian rhythm and breast and prostate cancer. & # 39;
The authors state that the exposure to blue light has increased rapidly due to the "massive use" of LED lights and smart phones and Tablets.
The role of melatonin in breast and prostate cancer is not yet understood, but it could prevent inflammation – the immune system's response to an infection associated with cancer.
There is less blue light in non-led light bulbs, but it still exists.The experts say that people spend one to two hours v Avoid bright lights and dimmers at bedtime.
