Lack of sleep in teenagers linked to increased risk of high blood pressure: Study |

Sleep plays a crucial role in maintaining good health, especially for teenagers. Recent research from Pennsylvania State University has found that lack of sleep, combined with insomnia, significantly raises the risk of high blood pressure in adolescents. High blood pressure, or hypertension, is a major risk factor for heart disease and other cardiovascular problems. This study highlights the importance of proper sleep habits in teenagers and shows that not getting enough sleep, especially less than 7.7 hours per night, can have serious health consequences. Understanding how sleep quality and duration impact teenage health is vital for preventing future heart-related illnesses.
Study finds insomnia and short sleep increase hypertension risk in teens
The study involved over 400 teenagers in the United States. Researchers looked at how insomnia and short sleep duration affected their blood pressure. Insomnia was defined as difficulty falling asleep or staying asleep, while short sleep was defined as less than 7.7 hours of sleep based on lab tests. The results showed that teenagers who had insomnia and slept less than 7.7 hours were five times more likely to develop clinical hypertension compared to those who slept well without insomnia. This reveals a strong link between poor sleep and high blood pressure risk in teens.
Importance of sleep duration and quality
Interestingly, teenagers who slept less than 7.7 hours but did not have insomnia were still nearly three times more likely to have elevated blood pressure than good sleepers. On the other hand, teenagers who reported insomnia symptoms but still managed to get enough sleep did not show a higher risk for hypertension. This suggests that both sleep duration and sleep quality are important factors in maintaining healthy blood pressure levels.
How much sleep do teenagers require
According to the American Academy of Sleep Medicine, teenagers require 8 to 10 hours of sleep every night to function well and maintain good health. However, most high school students get an average of only 6.5 hours of sleep per weeknight, which is far below the recommended amount. This widespread sleep deficit among teens is a growing health concern because it increases the risk of developing high blood pressure and other cardiovascular diseases later in life.
Why sleep health matters for teenagers
Professor Julio Fernandez-Mendoza explained that poor sleep is a known risk factor for high blood pressure in adults, but this association had not been clearly studied in teenagers before. This new research shows that addressing sleep problems early can help protect heart health in adolescence and adulthood. Monitoring sleep patterns can also help identify teenagers who are at higher risk due to severe insomnia combined with short sleep duration.
What parents and teens should know
Not all teenagers who experience insomnia symptoms will develop high blood pressure. However, when insomnia is paired with insufficient sleep, the risk rises sharply. Parents and healthcare providers should encourage healthy sleep habits and ensure teens get enough quality sleep. Simple lifestyle changes, such as reducing screen time before bed and maintaining a consistent sleep schedule, can improve sleep quality and help prevent hypertension.
The link between teen sleep and heart health
This important study underscores the critical role of sleep in teenage health. With rising cases of sleep deprivation among adolescents, understanding its impact on blood pressure is key to preventing future cardiovascular problems. Prioritising good sleep habits during the teenage years can support overall well-being and reduce the risk of heart disease later in life.
