Shift work is bad for your sleep, and lack of sleep can contribute to diabetes. Rotating shift work that overlaps with midnight to 6 am, leads to a 37% increase in diabetes risk in men and a 9% increase in diabetes risk in women. The more years of shift work someone works, the greater will be their risk of developing diabetes. Diabetes, in turn, increases the risk of heart disease.
This row of “bad health dominoes” makes it all the more important for shift workers to keep regular appointments with a primary care provider. That way, if chronic disease begins to develop, you have enough warning to make major lifestyle changes before things get worse.
