According to a new study, both the amount and quality of sleep in teenagers have significant effects on cardiovascular health. The investigation revealed that only 2% of the adolescents are having a good night sleep and that a poor sleep exposes to heart diseases.
The study, conducted by a team of researchers headed by the Massachusetts Children’s General Hospital (MGHfC) in the United States, showed that both the amount and quality of sleep in teenagers could have critical impacts on cardiovascular health aspects, such as blood pressure, blood cholesterol levels, and belly fat amount.
This research is the most recent update coming from the Viva Project, a long-running project conducted at the Harvard Pilgrim Health Care Institute involving over 2,000 women and their offspring registered from 1999 to 2002. The participants in the survey have been monitored consistently for the past two decades, with periodical reports of contributing factors concerning children’s development and their both mental and physical wellbeing.
Poor sleep exposes to heart diseases in teenagers
This most recent survey reported the researchers’ findings after collected and analyzed the data from 829 participants. The researchers analyzed teenagers who, in conjunction with an in-person assessment, had their night-time sleep and everyday physical activity recorded over 7 to 10 days
The attendees, who were on average about 13 years old, also filled out detailed sleep logs. Besides the duration of sleep, the researchers also gauged the efficiency of rest which is the exact amount of time when a person is actually asleep over the night, an indicator of both the quality and continuity of night-time sleep.
The data indicated that the overall average sleep length for all participants was 441 minutes or 7.35 hours per day, while only 2.2% achieved or surpassed the recommended sleep duration for their age category, which is of 9 hours per day (between 11 and 13 years old) and 8 hours per day (between 14 and 17 years old).
On the other hand, both reduced sleep duration and lower sleep efficiency were linked to increased levels of both overall fat and abdominal fat deposits. Also, poor sleep exposes the heart diseases in teenagers, the scientists found.
“Normal amount and quality of sleep are pillars of health along with diet and physical activity,” concluded Elizabeth Cespedes Feliciano, the study’s leading author.
