Exposure To Night Light may Increase The Risk Of Leukemia
A pitch-black room may be the healthiest environment for your child at bedtime. According to new research , increased light at night may put children at risk for leukemia. Researchers have determined that light at night is found to disrupt the circadian rhythm and suppress the production of melatonin.

As an antioxidant, in many studies melatonin has been shown to protect DNA from oxidative damage. Once damaged, DNA may mutate and carcinogenesis may occur. Past research has found a correlation between night workers and an increased risk for breast cancer, further supporting the theory that light at night is a risk factor for leukemia.

Researchers conclude saying that if melatonin levels are altered by magnetic fields, a potential relationship between these fields and cancer, including leukemia, would be possible.
