Night Shifts May Be Wrecking Your Health
(Ivanhoe Newswire) – A new Canadian study involving over 2,000 women found that individuals who work night shifts for 30 years or more have double the risk of developing breast cancer, regardless of what kind of job they have.
It is believed that working night shifts raises the likelihood of breast cancer because the sleep hormone melatonin is disrupted, which may cause more estrogen to be produced. However, other problems with night shift work such as, sleep disturbances, upset body rhythms, vitamin D, or lifestyle differences, should also not be discounted as possible factors.
