Effects of split and continuous sleep schedules and total sleep opportunity in adolescents

Takeaway

  • Adolescents can adopt a split-sleep schedule with minimal effect on basic cognitive functions provided the total amount of sleep across a 24-hour period is ~8 hours.

Why this matters

  • Nocturnal sleep curtailment in adolescence and its impact on cognitive function is an area of growing interest in sleep medicine, particularly relating to school performance and mood.

  • Preliminary studies show that split sleep may be beneficial; however, the impact of different sleep patterns on behavioral and cognitive domains is not well understood.
