London: Simply turning on a light at night for a few seconds to go to the toilet can cause changes that might lead to cancer, scientists claim. Researchers in the UK and Israel found that when a light is turned on at night, it triggers an "over-expression" of cells linked to the formation of cancer.
"We believe that any turning on of artificial light in the night has an impact on the body clock. It`s a very sensitive mechanism. If you want to get up to go to the toilet, you should avoid reaching for the light switch. There are some plug-in lights that just glow, that are safe and you could use them as an alternative," Rachel Ben-Shlomo, of the University of Haifa, was quoted as saying. IANS
