Turn on the light when going to the night toilet, does it cause cancer?

Turning on the light for a few seconds to go to the night toilet is enough to destroy the body's cell division process, leading to cancer, both British and Israeli scientists have confirmed.

"The destruction of physiological cell division in the body is a feature of cancer. So this problem is important to be explored," the researchers said.

According to Newswise, previous studies have found a link between an increase in breast cancer and prostate cancer in night shift workers.

But this latest study is the first to show that even very short exposure to light in the night increases the risk of cancer.

Tests were performed on mice at the University of Leicester, conducted by genetics professor Charalambos Kyriacou.

In the experiment, a group of mice were exposed to night light for one hour. When compared to mice that were in the dark, they found that their brains had changes in cells responsible for the biological clock that controlled the body's functions.

"We believe that all lights turned on at night have an effect on the biological clock. It's an extremely sensitive mechanism. If you want to go to a toile, avoid turning on the light. You can replace it with a lamp. Sleeping is only a little dim, it will be safer, "said Dr. Rachel Ben-Shlomo, from Haifa University.

She also said this new finding is a very preliminary study, and needs to be investigated further.
