Exposure to light from street lamps and mobile phones can trigger risk of cancer, according to a new research. Modern street lamps are increasing the risk of prostate and breast cancer by alerting hormone levels.
The study discovered that the risk of developing prostate cancer among men who are exposed to blue light at night has become double while women exposed to the light have 1.5 times higher risk of developing breast cancer.
Scientists have found a “strong association” between the new generations of street lights risk and the disease. They have advised officials to think about limiting the roll-out of LED (light-emitting diode) lights.
The study published in the journal Environmental Health Perspectives claims that exposure to light from street lamps and mobile phones can increase the cancer risk. It looked at the medical and epidemiological data of more than 4,000 men and women aged between 20 and 85 in 11 different Spanish regions.
The research conducted by the research team at the University of Exeter and the Barcelona Institute for Global Health (ISGlobal) discovered that LED light, which emits mainly blue light, may disrupt the body’s internal clock and hormone levels to cause cancer. Their research may also show the involvement of using mobile phones and tablets at nighttime which emit blue light, in cancer development.
“Given the ubiquity of artificial light at night, determining whether or not it increases the risk of cancer is a public health issue.” said first author Dr. Ariadna Garcia, of ISGlobal.
“At this point, further studies should include more individual data using for instance light sensors that allow measuring indoor light levels,” “It would also be important to do this kind of research in young people that extensively use blue light emitting screens.”
