Calling all those who are sleep-deprived: We interrupt your yawns with an important announcement. If you re trying to get by on about six hours or less of sleep a night during the workweek, you re setting up your brain for future failure, according to a new study published Tuesday in the journal Nature Communications. After following nearly 8,000 people for 25 years, the study found a higher dementia risk with a sleep duration of six hours or less at age 50 and 60 as compared to those who slept seven hours a night. In addition, persistent short sleep duration between the ages of 50, 60 and 70 was also associated with a 30 per cent increased dementia risk, independent of sociodemographic, behavioural, cardiometabolic, and mental health factors, including depression, the study said.
Researchers followed 8,000 people over the course of 25 years and discovered that a short night s sleep increased dementia risk, independent from sociodemographic, behavioral, cardiometabolic and mental health factors, according to CNN.
Sleep is essential for normal brain function, Tara Spires-Jones, the deputy director of the Centre for Discovery Brain Sciences at the University of Edinburgh in Scotland, said in a statement.
Without enough sleep, the brain cannot function properly and can impair your abilities to concentrate, think clearly and process memories, according to the Sleep Foundation. Lack of sleep has also been linked to Type 2 diabetes, obesity, high blood pressure, heart disease, stroke, poor mental health and early death.
