It is recommended to have at least six eight hours of sleep for the healthy functioning of the body. While insomnia is becoming a common issue. Oversleeping should also not be overlooked as it can increase your risk of stroke.

While oversleeping might seem like a luxury on weekends, sleeping too much on a daily basis can indicate a medical concern. Studies have shown that people who sleep for more than eight hours every day are more likely to suffer a stroke as compared to people who sleep between six to eight hours.

Due to a sedentary lifestyle, people as young as 25 are dying due to cardiac arrest leading to stroke.
The study

Scientists evaluated the risk of stroke among 32,000 people with an average of 62 in the online edition of the journal Neurology, the American Academy of Neurology's medical journal on December 11, 2019.

The scientists linked stroke rates to self-reported sleep patterns of the study participants.

A stroke happens when the blood flow to a portion of the brain is disrupted or diminished, causing damage to the brain tissue.

Further, people who nap for at least 90 minutes in the middle of the day have 25 per cent higher chances of having a stroke than those who took less than 30 minutes of nap.

People who sleep for longer but report having poor sleep are at 82 per cent increased risk of stroke. Sleep issues are frequent even after a stroke.
