Working long hours and getting little sleep or time off is a sure-fire shortcut to an early grave. According to a new Anglo-Japanese study "working 60 or more hours a week, and regularly not getting much sleep, may double the risk of having a heart attack." An average night's sleep of five or fewer hours, for two nights of the working week, was associated with a doubling and even tripling of the risk. The study, conducted between 1996 and 1998, looked at 260 men aged between 40 and 79 who had survived a first heart attack and matched them against 445 comparable men with no history of cardiac arrest. All were questioned closely about their work, relaxation and sleep patterns as well as other key areas such as lifestyle, weight, diet, blood pressure, cholesterol and diabetes. The study found that while all participants had similarlifestyles and medical conditions, the heart attack group worked for longer hours, hardly relaxed and slept less than five hours a night significantly more often than the other group.
Sleep deprivation may lead to increased blood pressure.
