Shorter sleep duration and lower sleep quality have been linked to a higher risk of diabetes and heart disease, even among young adults. Factors such as socioeconomic status, race, ethnicity, and discrimination can further affect sleep quality and health outcomes.
During adolescence, teenagers naturally tend to stay up later as their internal biological clocks mature. However, school schedules often require students to wake up earlier than their bodies prefer, leading to sleep deprivation. Over time, chronic sleep deprivation may contribute to various health problems, including cardiovascular disease.
The recommended amount of sleep for teenagers aged 12–18 is 8–10 hours per night. Unfortunately, many teens do not get enough sleep due to academic pressure, extracurricular activities, social commitments, and increased screen time.
In most cases, it is beneficial for parents and teens to work together to establish healthy sleep habits. Avoiding caffeinated drinks in the evening and keeping screens out of the bedroom are simple but effective ways to improve sleep quality and reduce long-term health risks. Personally, I believe the “no phones in the bedroom” rule is especially beneficial for students and young adults. As someone who follows this rule, I have found it much easier to fall asleep without the constant temptation to check notifications or social media, despite experiencing severe FOMO (fear of missing out).
Healthy sleep habits can begin even earlier in childhood. Having a consistent bedtime routine helps children recognize when it is time to sleep and may encourage healthier sleep patterns later in life.
While improving individual sleep habits is important, broader social factors should also be considered. Revisiting school start times may be an important step toward supporting teenagers’ natural sleep rhythms and promoting long-term heart health. Aligning school schedules more closely with adolescent biological development could help reduce sleep deprivation and improve overall well-being.
Heart disease may seem like a distant concern for teenagers, but healthy habits often begin long before symptoms appear. By prioritizing sleep today, young people may be taking an important step toward protecting their heart health for decades to come.
