Naturally occurring circadian rhythm and sleep duration are related to executive functions in early adulthood

In conclusion, naturally occurring insufficient sleep and later circadian rhythm showed modest associations with poorer executive function. Shorter habitual sleep duration was associated with lower scores of performance‐based tests of executive function, and later circadian rhythm was associated mainly with poorer trait‐like executive function characteristics. Our findings suggest additionally that sleep duration and circadian rhythm associate with different domains of executive function, and there are no additive effects between the two.
