Researchers from Laval University, Quebec say that chronic job stress can raise blood pressure. This is especially true of white-collar workers.
The research, appearing in the American Journal of Public Health, found that low support levels and tight deadlines increased blood pressure especially in men. The study followed 6,719 workers over more than seven years. "Our study supports the hypothesis that job strain, particularly in workers with low social support at work, may contribute to increased blood pressure," said lead researcher Dr Chantal Guimont.
Previous studies had found that stress could lead to ill health, but effects on blood pressure have so far produced mixed results. But the current study says that stress is bad for blood pressure.
