Shift work may be very common in today’s workplaces and across all professions. But while shift work may have become a part of everyone’s lives, it is extremely harmful to your health, according to a study by the Huazhong University of Science and Technology in China. Specifically, it was found that shift work was closely linked to an increase in the risk of cardiovascular diseases. The reason why shift work poses so many dangerous risks is that working in shifts could disrupt the normal sleep-wake cycle which could increase stress on the heart. The study, published in the journal Occupational Medicine, showed shift workers were 13 per cent more likely to develop coronary heart disease than daytime workers. Not just this, for every year spent working in shifts, there was a one per cent increase in the risk of coronary heart disease. Sadly, there are many other risks involved when you do shift work.
