A new scientific study revealed that sleeping about five hours a night increases the risk of stroke and heart attack, indicating that the incidence may reach 70%.
The study showed that middle-aged women who sleep less than five hours each night are 75% more likely to suffer from heart failure or stroke, according to the British Daily Mail website.
Scientists at the University of Pittsburgh followed nearly 3,000 women between the ages of 42 and 52 over a period of 16 years.
Every year for about two decades, the women completed questionnaires about their sleep, including how many hours they slept on average each night, whether they considered themselves insomniacs, and filled out health questionnaires to keep a record of ongoing illnesses or problems.
Analysis of the data revealed that women who regularly slept less than five hours of sleep per night were more likely to have cardiovascular problems and coronary artery disease.
Surprisingly, this relationship remained true even when other potentially contributing factors, such as body mass index and underlying health conditions, were taken into account.
Scientists explained that this may be because lack of sleep can raise blood pressure and lead to insulin resistance, which increases the risk of blood vessel damage. They also warned that it increases the risk of obesity, which is known to affect heart health, due to the release of hunger and fullness hormones in the body.
But surveys indicate that one in three adults regularly fail to achieve this goal.
Surveys among middle-aged women indicate that half of them fail to get the recommended seven hours of sleep each night.
“Insomnia symptoms, when they persist into middle age or occur with short sleep, are associated with a higher risk of cardiovascular disease among women,” wrote the study authors, led by cardiologist Dr. Rebecca Thurston.
