Can you get cancer from sleeping?

Disruptions in the body’s “biological clock,” which controls sleep and thousands of other functions, may raise the odds of cancers of the breast, colon, ovaries and prostate.

Exposure to light while working overnight shifts for several years may reduce levels of melatonin, encouraging cancer to grow..

Does melatonin fight cancer?

Melatonin also inhibits the growth of certain cancer cells including breast cancer and melanoma when directly applied to these cells. Studies in humans, however, do not show an anticancer effect. When used at the same time as specific chemotherapy drugs, melatonin may increase survival time.

Is it bad for a child to sleep with the light on?
