A global study by Keele University found that people who sleep more than eight hours a night are more at risk for heart disease and premature death than those who sleep less than 7 hours.
A study published in the Journal of the American Heart Association (JAHA) examined the link between self-reported sleep and cardiovascular disease and mortality. Scientists from Keele University, along with colleagues from the University of Manchester, the University of Leeds and the University of East Anglia, reviewed 74 studies of mortality and cardiovascular outcomes by indicators of duration and quality of sleep. Data on more than three million people were analyzed.
“This study started because we were interested to know if it was more dangerous to sleep less or more than the recommended seven to eight hours of sleep. We also wanted to know how gradually deviating from the recommended amount of sleep changed the risk of death and cardiovascular risk,”said lead researcher Dr. Chun Shing Kwok, of the Keele University's Institute of Medicine Science and Technology. for Science and Technology in Medicine).
According to the findings, sleep duration of about 10 hours is additionally associated with a 56% increase in the risk of death from stroke and a 49% increase in mortality from cardiovascular disease. In addition, poor sleep quality is associated with a 44% increase in coronary heart disease. Sleeping for 10 hours is associated with a 30% increased risk of premature death compared to sleeping within 7 hours.
The study's findings appear to be important for public health as they show that abnormally long sleep is a marker of an increased risk of cardiovascular problems. Therefore, clinicians should pay more attention to studying the duration and quality of sleep during consultations. If excessive sleepiness is found, especially over eight hours, consideration should be given to screening for adverse cardiovascular risk factors and apnea, a serious sleep disorder that occurs when a person's breathing is interrupted during sleep.
“Sleep affects everyone. The quantity and quality of our sleep is important. There are cultural, social, psychological, behavioral, pathophysiological and environmental influences on our sleep, such as caring for children or family members, irregular work shifts, physical or mental illness and 24-hour availability of goods in modern society,”sums up Chun Shing Kwok, calling for more attention to the study of sleep duration and quality.
It should be noted that the study was not reliable as information on sleep duration was self-reported by the participants and underlying mental or physical conditions may have influenced "extreme sleep patterns."
