Sleeping is known to be the best medicine to treat a lot of human diseases, but a new study suggests that people who sleep more than required have an increased risk of getting a stroke.
According to the study, people who nap regularly during midday for more than 90 minutes are 25 % more susceptible to have a stroke later in their life as compared to people who took naps of up to 30 minutes.
However, people who did not nap at all were not at all likely to have a stroke as compared to the ones who took naps of up to 30 minutes.
Author of the study said, studies have shown that long nappers and sleepers have unfavourable changes in their cholesterol levels and increased waist circumferences, both of which are risk factors for stroke.
Long napping and sleeping may suggest an overall inactive lifestyle, which is also related to increased risk of stroke, she added.
The study involved 31,750 people from China, having an average age of 61. The people who were involved in the study did not have any history of stroke when the study was started. The researchers followed the people for 6 years, during which a total of 1,557 cases of strokes were reported.
The conclusion drawn out of the study was that people who slept for 9 hours or more during the night were 23 % more susceptible of getting a stroke as compared to people who slept for 7 or fewer hours in the night.
The study found out that people who were both long sleepers and long nappers had 85 % likelihood of having a stroke than people who slept in moderation.
