Artificial Light at Night Raise Breast Cancer Risk

An interesting study shows that sleeping in a well-lighted environment lowers melatonin levels, and stimulates the growth of breast cancer cells! This also explains why night-shift workers have higher levels of cancer, and the blind have lower rates. The body produces the most melatonin in pitch darkness, so if you live near a street light, or have a spouse that absolutely demands a nightlight, you may want to invest in one of those things that covers your eyes at night! There is also the option of taking melatonin supplements, which are pretty cheap.
