After a day full of activity, of course you need time to rest. Sleep is one of the ways you usually do to rest your body and your brain. Not only that, a good sleep is also useful in maintaining hormonal balance and the immune system.

An adult is said to have a good sleep if he has 7-9 hours of sleep a day, while for elderly, 7-8 hours is the recommended time. Many studies have shown that sleep quality has an important role in maintaining your health. In the latest study conducted by Huazhong University of Science and Technology, researchers found that too much sleep was associated with a high risk of stroke, especially in elderly

The researchers collected data on 31,750 participants with an average age of 62 years in China. It was found that each participant did not have a history of stroke or other serious health conditions at the beginning of the study period. Each participant was asked to fill out a questionnaire about their sleep patterns, both night and day. Clinically, the researchers monitored all participants with an average follow-up period of 6 years.

Researchers found that there were 8% of participants who had a habit of taking a nap for more than 90 minutes, while there were 24% of participants known to have a duration of night sleep of more than 9 hours. During the follow-up period, there were 1,557 participants who had a stroke. Those who slept for more than 9 hours had a 23% higher risk of stroke compared to those who slept for 7-8 hours. In addition, researchers also found that the risk of stroke was 85% higher for those who slept for more than 9 hours while also took a nap for more than 90 minutes.
