Higher Rates of Breast Cancer Linked to Nighttime Lights
The Washington Post published a story last week reporting on the work of researchers in Israel. The scientists "overlaid satellite images of Earth onto cancer registries" and found that women who live in neighborhoods that have a lot of nighttime light, or those who work the graveyard shift, such as nurses and flight attendants, have a greater risk for breast cancer - as much as 60 percent higher. The key may be a lack of melatonin which is produced primarily at night; however, production of melatonin drops when light is present, especially light on the blue end of the spectrum, such as that from computer screens and fluorescent lights.
