Sleeping is the most important part of human life. If a person can sleep well, it’s a sign of healthy living. But now, according to research sleeping, more than 9 hours can increase the risk of incident stroke. Taking long mid-day naps is also not good for the health. According to the MD of Huazhong University, Science and Technology in China, sleeping more than nine hours compared to 7 to 8 hours of sleep can increase the risk of incident stroke by 23.1%. But sleeping six hours a day has no significant effect on stroke-related risk. If a mid-day nap lasts for more than 3 hours, it can boost the risk of stroke by 25%. Taking 30 minutes’ midday nap a day has no adverse effect on human health. In previous studies, it is stated that long sleepers and long nap takers are facing changes in their cholesterol levels. Also, they are facing the problem of increasing waist size. Both of the two factors are responsible for growing stroke-related risks.
Prior researches completed over ten years of span showed that irregular sleep patterns could increase the risk of cardiovascular diseases. A new study performed on the 31,750 retired employees of the firm known as Dongfeng Motor Corporation shows similar results. The average age of retired employees was 62 years, and researchers followed them for 6.2 years. The participants had no history of cardiovascular diseases and they filled questionnaires related to their sleeping patterns. From this, it is noted that 23.9% of participants sleep for long hours, which is up to 9 hours. And 7.6% were taking long mid-day naps as mid-day napping is common in China. After the 6.2 years, it is noted that 1,557 participants emerged with the problem of incident stroke. Over 29% of participants faced the problem of incident stroke.
But the people who were taking both long mid-day nap and sleeping more than 9 hours developed the risk of incident stroke about 85 % more than normal sleepers. Those who switched from normal sleeping to long sleeping boosted the danger of incident stroke by 44%. So for a healthy life, it is advisable to maintain normal sleeping hours.
