There are days when we are exhausted and overwhelmed. We are so tired that we could go to bed and sleep for ages. When you’re tired, you’re told you should get a good night sleep. It’s alright to sleep a little longer, but don’t overdo it, and don’t turn it into a habit.
Researchers from Keele University say that sleeping regularly for longer than 8 hours could be a sign of serious illness. According to the recent study, a sleep duration of ten hours is linked with 30% increased risk of dying compared to sleeping for seven hours.
The study, published in the Journal of the American Heart Association, examined the link between self-reported sleep and cardiovascular disease and mortality in more than three million participants.
The research found that a sleep duration of ten hours is further linked to a 56% increased risk of stroke mortality and a 49% increased risk of cardiovascular disease mortality.
Sleep is vital for staying healthy. But staying in bed too long can be very dangerous and if you feel you need too much sleep, you should talk to your doctor.
“Our findings have important implications as clinicians should have greater consideration for exploring sleep duration and quality during consultations. If excessive sleep patterns are found, particularly prolonged durations of eight hours or more, then clinicians should consider screening for adverse cardiovascular risk factors and obstructive sleep apnea, which is a serious sleep disorder that occurs when a person’s breathing is interrupted during sleep,” Dr. Chun Shing Kwok at Keele University’s Institute for Science and Technology in Medicine said in a press statement.
Still, remember that the amount of sleep depends from person to person. For example, genius Nikola Tesla never slept more than 2 hours a day, but most of us need much more sleep.

“Sleep affects everyone. The amount and quality of our sleep is complex. There are cultural, social, psychological, behavioral, pathophysiological and environmental influences on our sleep such as the need to care for children or family members, irregular working shift patterns, physical or mental illness, and the 24-hour availability of commodities in modern society,” Dr. Kwok added.
So, go to bed, get a good night sleep, but don’t forget to set the alarm clock and don’t be annoyed when it wakes you up after seven or eight hours. It would seem that ancient Greeks did us a great favor when they invented the alarm clock.
