A recent study found very interesting results in regards to sleeping patterns and the risk of stroke but with no clear answer as to how these things are connected. According to the study, the longer we sleep, the higher the risk of developing strokes.
Results showed that, in comparison to people sleeping between 6 and 8 hours per night, those who get more than eight hours of sleep increased their risk of developing strokes by 46 percent over a period of 10 years.
The British scientists who conducted the experiment also found that people who modified their sleeping habits from less than 6 hours to more than 8 had a 4 times higher risk of suffering from stroke later on in life.
Up until now, the team is unable to explain the mechanism behind the process since there are very few studies that found a strong link between these two aspects. But they are certain that sleeping too much increases the risk of stroke.
For the study, the scientists used a previous cancer study entitled the European Prospective Investigation of Cancer conducted over a period of almost about 10 years. Over 9,500 British people participated in the cancer study. All of them were between the ages of 40 and 79.
Another purpose for the European Prospective Investigation of Cancer study was to analyze sleeping habits. All participants had to fill out a survey regarding the number of hours slept per night and the quality of sleep.
In addition to this, the British researchers looked at other factors that could have influenced the risk of stroke: age, smoking, body mass index (BMI), cardiovascular disease, family history.
The team found that approximately 350 participants experienced a stroke during the survey, 67 of them being fatal. After adjusting for the factors that increase the possibility of stroke, the team concluded that those who slept more than 8 hours (“the long sleepers”) had a higher possibility of developing strokes. They also noticed that the female participants who slept more than the healthy limit were even more predisposed to strokes than male long sleepers.
The results were publishes in the Neurology journal on Feb. 25.
