The first results from the world’s largest sleep study have been published, concluding that between seven and eight hours of sleep is the ideal range for optimal cognitive performance. The study convincingly revealed that too much sleep interestingly correlated with similar cognitive deficits associated with too little sleep.

Sleep is important, and vital for effective cognitive functioning. This has been established by a number of comprehensive studies over many years. However, it is not clear exactly how impaired sleep affects different cognitive domains, and how these cognitive effects relate to variations in sleep duration. This new study offers the most granular insight into these questions gathered to date.

“We really wanted to capture the sleeping habits of people around the entire globe,” explains Adrian Owen, one of the researchers working on the project. “Obviously, there have been many smaller sleep studies of people in laboratories but we wanted to find out what sleep is like in the real world.”
