People who work in shifts are at high risk of developing heart disease, as per a study conducted by Chinese scientists.
The study which was published in the journal Occupational Medicine, said the risk increases with years they work in shifts.
Shift work “can earn more profit, but it can also cause harm to the health of employees. Thus, employers should reduce shift work as much as possible,” lead author Weihong Chen, a researcher in occupational and environmental health at Huazhong University of Science and Technology in Wuhan, was quoted as saying to Health Day, a news website.
The scientists have yet not zeroed in about the exact cause, but believe that disruption in the normal sleep-wake cycle could increase stress, making them vulnerable for coronary heart disease.
In the study the team analysed data from 21 earlier studies involving over 3, 20,000 people and nearly 20,000 cases of patients suffering with heart disease. The data showed shift workers were 13 per cent more likely to develop coronary heart disease than daytime workers.
For every year spent working in shifts, there was a nearly one per cent increase in the risk of coronary heart disease, the report said.
