Researchers from the University of Buffalo in the U.S. have been looking into the effects of stress on police officers. Research so far has shown that officers are at greater risk of high blood pressure, insomnia, raised levels of stress hormones, heart problems, post-traumatic stress disorder and suicide. Officers over 40 were more at risk of heart problems than the national average, 72% of female officers and 43% of male officers had higher-than-average cholesterol levels and police officers as a group had higher-than-average pulse rates and blood pressure. Suicidal thoughts were found to be higher in women working on the day shift and in men working on the afternoon/night shift. The female police officers were found to have high cortisol levels - which have been linked to cardiovascular disease - throughout the day.
