Link Between Sleep Issues in Early Adolescence and Future Self-Harm Risk

Recent research emphasizes the significant impact of sleep disturbances in early teens on the likelihood of engaging in self-harm later in adolescence. Published in the Journal of Child Psychology and Psychiatry, a study conducted by the University of Warwick and the University of Birmingham analyzed data from over 10,000 teenagers through the Millennium Cohort. The researchers focused on various sleep parameters, including the amount of sleep during school nights, sleep onset latency, and nighttime awakenings, and their association with self-harm behaviors.

Dr. Michaela Pawley, the lead author, explained that teenagers asked about their sleep patterns at age 14 and were surveyed again at 17. Findings indicated that shorter sleep duration on school days, longer time to fall asleep, and more frequent night awakenings at age 14 were correlated with self-harm both concurrently and three years later. Importantly, sleep problems remained a relevant risk factor even after accounting for variables like socioeconomic status, previous self-harm, self-esteem, and depression levels.

Professor Nicole Tang highlighted that self-harm is a leading cause of death among adolescents, and recognizing sleep issues as a potential early warning sign offers new avenues for prevention. Interestingly, the study found that poor sleep was not explained solely by impaired decision-making, suggesting that other mechanisms are involved. Overall, the findings underline the importance of prioritizing sleep health during adolescence, offering a modifiable factor that, if addressed through targeted interventions in schools and homes, could diminish the risk of self-harm.

Sleep health in teens is often overlooked despite its long-term implications. Addressing sleep problems during this critical developmental phase could serve as a crucial strategy in mental health prevention and promote overall adolescent well-being.
