The negative effects of sleep deprivation — memory and concentration problems and increased risk of obesity, diabetes and heart disease– have been well known; interestingly, a new study suggests oversleeping may also be bad for us: it could significantly increase the risk of stroke. This finding was published by a research team at the University of Cambridge in the UK, in the journal Neurology. The study, involving more than 9,000 people with an average age of 62, found that getting more than 8 hours sleep each night was associated with a 46% increased risk of stroke. Based on their findings, it is unclear as to whether sleeping more than 8 hours a night is a cause or result of stroke. These researchers suggest that extended sleep duration would more likely serve as an early warning sign of increased stroke risk, particularly in older people.
