Overview

• Among 390 young adults (mean age 24), elevated neuroticism and reduced conscientiousness and extraversion correlated strongly with bedtime procrastination.
• Participants completed chronotype questionnaires and maintained sleep diaries for 14 days to isolate personality influences from innate circadian preferences.
• Bedtime procrastination was linked to depressive-like emotional patterns, with individuals reporting fewer positive experiences and heightened negative affect instead of seeking stimulation.
• The research distinguishes bedtime procrastination from simple planning failures by highlighting pre-sleep affective dysregulation as a central mechanism.
• Investigators plan to explore whether interventions that lower pre-bedtime anxiety can effectively reduce bedtime procrastination.
