Healthy Sleep and Smart Choices

 When people think about preventing youth substance misuse, they often imagine classroom lessons, parent talks, or community events. What many don’t realize is that one of the most powerful protective factors against risky behavior is something far simpler: sleep.




Why Sleep Matters for Teens

The Centers for Disease Control and Prevention (CDC, 2022) recommends that teenagers get 8–10 hours of sleep each night. Yet surveys consistently show that most teens average far less, often only 6–7 hours. Busy school schedules, extracurricular activities, late-night screen use, and stress all cut into rest.

The consequences go well beyond tiredness. Lack of sleep has been linked to impaired judgment, poor academic performance, and an increased likelihood of engaging in risky behaviors, including substance use. The CDC reports that sleep-deprived students are more likely to report drinking alcohol, using marijuana, and experiencing depressive symptoms.

The Connection Between Sleep and Substance Use

Many teens turn to substances like alcohol or marijuana in an effort to “relax” or help them fall asleep. Unfortunately, these substances do the opposite. Alcohol interferes with deep, restorative stages of sleep, while marijuana disrupts REM cycles, which are critical for memory and learning. Rather than promoting healthy rest, these substances leave teens groggy, irritable, and more impaired the next day.

The National Institute on Drug Abuse (NIDA, 2023) notes that disrupted sleep cycles contribute to poor emotional regulation and higher impulsivity — both of which make teens more vulnerable to substance misuse. In other words, lack of sleep and substance use can create a dangerous cycle, where poor sleep increases risk-taking, and substance use further erodes healthy rest.

Benefits of Healthy Sleep

On the flip side, when teens get enough rest, the results are dramatic:

  • Improved academic performance: Rested brains process and retain new information more effectively.

  • Better emotional health: Adequate sleep reduces stress, anxiety, and depression risk.

  • Stronger decision-making: Well-rested teens are less impulsive and more capable of resisting peer pressure.

  • Enhanced physical health: Sleep supports immune function, growth, and recovery, which are critical for athletes and active students.

What Parents Can Do

Parents play a major role in shaping routines that prioritize rest. Here are practical steps to support teens:

  1. Model Healthy Routines
    Teens learn as much from what we do as what we say. Setting a family bedtime routine, reducing late-night screen use, and prioritizing sleep sends a clear message that rest is valuable.

  2. Set Tech-Free Zones
    Devices are one of the biggest culprits in poor sleep. Encourage phones and tablets to be left in a common charging station at night, rather than bedrooms.

  3. Balance School and Activities
    It’s easy to overschedule. While sports, jobs, and clubs are important, students need balance. Ensure commitments don’t consistently cut into healthy sleep.

  4. Encourage Stress-Management
    Talk openly about stress and provide outlets like exercise, journaling, or relaxation practices. Healthy coping reduces the temptation to self-medicate with substances.

  5. Connect Sleep to Goals
    If your teen cares about sports, music, or academics, explain how sleep is a “performance booster.” Conversely, show how alcohol, vaping, or marijuana disrupt the very goals they are working toward.

Building a Culture of Health at Home

When families make sleep a priority, they send a strong prevention message. Just as important as saying “no” to substances is saying “yes” to wellness — sleep, nutrition, activity, and connection. Together, these protective factors form a foundation where teens are healthier, happier, and less likely to misuse substances.

Prevention doesn’t always require a campaign or a billboard. Sometimes, it starts with something as simple as lights out at a reasonable hour.

National Surge in Pediatric THC Poisonings Over the Past Five Years

Image
Over the last five years, the United States has seen an alarming rise in children accidentally ingesting THC , the psychoactive chemical in marijuana. Tetrahydrocannabinol (THC) is what produces the marijuana “high,” and when kids get into THC-infused products, the results can be dangerous. Recent data show that pediatric THC poisonings have skyrocketed. New research recorded a 1,375% increase in the number of young children (mostly toddlers) accidentally poisoned by cannabis edibles since 2017 ​  web.musc.edu   In raw numbers, cases rose from roughly 200 per year in 2017 to over 3,000 per year in 2021 ​  pbs.org  – more than 7,000 cases in total during that period. Health experts are sounding the alarm about this trend and urging stronger prevention measures. A Five Year Spike in Accidental Exposures Several factors contribute to the surge in pediatric THC exposures . The period of 2017–2021 coincides with many states legalizing medical or recreational cannabis, me...

Critical Issue: Underage Drinking

Image
 Underage drinking is a critical issue that, as Brown & Crouppen highlights, “can lead to devastating consequences for the minors themselves and those around them.” Their webpage underscores how early alcohol use poses significant health risks and legal ramifications. Individuals who drink before the legal age risk impairing brain development, which can influence memory, coordination, and long-term cognitive functions. Moreover, Brown & Crouppen explains that penalties for underage drinking may include driver’s license suspension, mandatory community service, steep fines, or even jail time in severe cases. The article also notes how adolescents often underestimate the dangers of alcohol, leading to increased injury risks, risky behavior, and involvement in serious car accidents. By detailing the physical, psychological, and social harm associated with underage drinking, Brown & Crouppen emphasizes the importance of parental involvement and community education initiative...

The Evolution of America’s “Fourth Wave” Overdose Crisis

Understanding the Four Waves of the Opioid Crisis: We often hear about the opioid epidemic, but it’s not a single monolithic event – it’s evolved in waves. To set the stage, Wave 1 started in the late 1990s with a surge in prescription opioid use (think OxyContin and Vicodin overprescribing). Wave 2 saw many people transition to heroin around the 2010s as prescriptions became harder to get. Wave 3 hit in the mid-2010s with the emergence of illicit fentanyl , a synthetic opioid vastly more potent than heroin, driving overdose deaths to new peaks. Now, we’re in what experts call the “Fourth Wave” – characterized by polysubstance overdoses, especially fentanyl mixed with other drugs like stimulants (cocaine, methamphetamine) uclahealth.org . This means people aren’t just overdosing on opioids alone; often it’s fentanyl combined with meth or cocaine (sometimes intentionally, sometimes unbeknownst to the user). From 2010 to 2021, the proportion of U.S. overdose deaths involving both f...
