According to a new study the healthiest environment for your child at bedtime would be a pitch-black room as researchers say increased light at night may put children at risk for leukemia.
In the 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 have determined that light at night is found to disrupt the circadian rhythm and suppress the production of melatonin. Researchers also says, "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."
Thus researcher conclude saying that if melatonin levels are altered by magnetic fields, a potential relationship between these fields and cancer, including leukemia, would be possible.
