A new study involving 10,000 civil servants aged between 35 and 55 over 12 years found that chronic work stress raised the risk of coronary heart disease (CHD) and this association was stronger among the under 50.
Stress appeared to undermine the autonomic nervous system that controls the heart and the variability of the heart rate. Researchers also found higher levels of the stress hormone in workers who reported stressful job.
