Introduction to the Study on Insomnia and Substance Use
A good night’s sleep is essential for children’s health and development, but childhood sleep patterns may also be linked to future substance use. A new study, led by a team of Penn State researchers, found that adolescents were more likely to have consumed alcohol or tried marijuana by age 15 if they went to bed later and slept fewer hours during childhood and adolescence. The team published their findings in *Annals of Epidemiology*.
The research team explored childhood sleep at different developmental stages within the same sample of children to see if there’s an impact on later substance use, which few studies have investigated. They focused on two different facets of sleep health—total duration of sleep and time of sleep or bedtime. The researchers explained that if children, especially school-aged children, go to bed later, it could affect their ability to sleep well.
Key Findings on Insomnia and Adolescent Substance Use
The study drew on data from 1,514 children in the Future of Families and Child Wellbeing Study, a diverse longitudinal birth cohort of children from 20 cities across the United States. Parents reported their child’s regular weekday bedtime at ages three, five, and nine. They also reported their child’s sleep duration at ages five and nine.
- Teens were 45% more likely to try alcohol by age 15 if they had a later bedtime at age nine when compared to other children with earlier bedtimes at age nine. However, bedtime at age five wasn’t associated with future alcohol use, nor was sleep duration at ages five or nine.
- When it came to marijuana use, later bedtime at age five was associated with 26% increased odds of trying marijuana by age 15, while sleeping an hour less at age nine was associated with 19% increased odds of trying marijuana by age 15.
The research team also examined data from adolescents at age 15, who self-reported their bedtime, sleep duration, and alcohol and marijuana use. They found that teens with a later bedtime had a 39% greater chance of drinking alcohol and a 34% greater chance of trying marijuana. Sleeping one hour less was associated with 28% increased odds of ever trying alcohol but wasn’t associated with marijuana use.
The findings highlight the critical role of sleep across multiple aspects of long-term health and wellbeing, researchers said. For school-age children, creating an environment that’s conducive for sleep and establishing an age-appropriate bedtime are key elements for cultivating good sleep.
“Exploring the connection between sleep and substance use is a critical area of research because we continue to struggle with an epidemic of opioid addiction and substance use,” Chang said. “It’s an important area to continue to research and to disseminate our research findings to the broader population, families, and health care professionals.”
Mechanisms Linking Poor Sleep to Increased Substance Use
So, how exactly does poor sleep lead to a higher likelihood of substance use in adolescents? The researchers believe that late bedtimes and shorter sleep durations can significantly affect decision-making and impulsivity. When kids don’t get enough sleep, their brains don’t function at their best. This can lead to poor decision-making and increased impulsivity, which are both risk factors for engaging in risky behaviors like substance use.
Sleep plays a crucial role in brain development, especially during childhood and adolescence. The brain is highly plastic during these stages, meaning it’s more adaptable and capable of change. Healthy sleep supports this neural development, helping kids grow into well-adjusted adults. On the flip side, poor sleep can have long-term effects on both physical health and behavior, potentially setting the stage for substance use later in life.
Data and Methodology of the Sleep Study
The study utilized data from the Future of Families and Child Wellbeing Study, which is a diverse longitudinal cohort of 1,514 children from 20 cities across the United States. This extensive dataset allowed the researchers to track sleep patterns and substance use over a significant period.
The findings were clear: later bedtimes and shorter sleep durations were associated with a higher likelihood of substance use by age 15. This highlights the importance of establishing good sleep habits early on and maintaining them through adolescence.

By understanding the mechanisms linking poor sleep to increased substance use and examining the data and methodology behind these findings, we can better appreciate the importance of good sleep habits. This knowledge can guide parents, educators, and healthcare professionals in creating environments that promote healthy sleep, ultimately reducing the risk of substance use in adolescents.
Implications for Prevention and Intervention
The findings from this study underscore the importance of targeting sleep health in school-age children as a preventive measure against future substance use. By establishing healthy sleep habits early on, parents and educators can help mitigate the risk factors associated with poor sleep, such as impaired decision-making and increased impulsivity.
- Establishing Appropriate Bedtimes: One of the most effective strategies for promoting good sleep health is setting consistent and age-appropriate bedtimes. Parents should ensure that children go to bed early enough to get the recommended amount of sleep for their age group. This can help regulate their sleep patterns and improve overall sleep quality.
- Creating a Conducive Sleep Environment: The sleep environment plays a crucial role in the quality of sleep. Parents should create a quiet, dark, and cool bedroom environment to promote better sleep. Limiting screen time before bed and establishing a calming bedtime routine can also help children wind down and prepare for sleep.
Broader Impact and Future Research Directions
The ongoing challenges of substance use epidemics, including the opioid crisis, highlight the need for continued research into the factors that contribute to substance use. This study adds to the growing body of evidence that sleep health is a critical component of overall well-being and can influence behaviors related to substance use.
- Role of Sleep Research: Sleep research is essential for understanding the complex interactions between sleep, brain development, and behavior. By identifying the mechanisms through which poor sleep affects decision-making and impulsivity, researchers can develop targeted interventions to improve sleep health and reduce the risk of substance use.
- Contributions and Support: The contributions of various researchers and the support from national institutes and foundations have been instrumental in advancing our understanding of sleep and its impact on health. Continued funding and collaboration will be crucial for future research efforts.
Future research should explore the long-term effects of sleep interventions on substance use and other health outcomes. Longitudinal studies that follow children into adulthood can provide valuable insights into how early sleep patterns influence lifelong health and behavior. Additionally, research should investigate the potential benefits of incorporating sleep health education into public health initiatives and school programs.
