Women who are working in night shifts for more than three decades are in increased risk (about double) of developing cancer in their breast, according to new findings. This may be related to decreased melatonin production in these women. Melatonin is a hormone that is produced in dark and is responsible for maintaining our day and night circadian rhythm. Since night shift working don’t allow one to sleep, melatonin production is dampened therefore.
