Teenagers And Sleep Disorder Risk

The importance of sleep for kids and teenagers is very well known. As one of the recent studies have shown, today’s teenagers should have at least 7 hours of sleep every night (read more about this study about teenagers and sleep needs of theirs). At the same time, a great number of parents and moms report about their teenage sons or daughters hardly getting the required 7-hour sleep since they spend pretty much of time at their PCs or watching TV shows till very late time, etc. Most of today’s teenagers go to sleep way after midnight, cutting their sleep hours down to 5-6 hours a night. Can this tendency be dangerous and can the links between the health of teenagers and sleep irregularities cause serious risk to their health? Teenagers And SleepA group of scientists at the Hospital for Sick Children in Toronto, Canada, carried out a study in order to find a possible answer to this question. Their findings were recently published in the Canadian Medical Association Journal.

The scientists analyzed the information on about 4,100 teenager, from secondary school¬† students to freshmen. It turned out that, first of all, there are very strong links between a lack of sleep or poor sleep and teenagers cardiovascular health. As the analysis has shown, every one of three teenagers who had reported about the problems like poor night’s sleep, inability to fall asleep, staying awake for a long time at night, and others, had high cholesterol levels and increased body mass. In addition, most of such participants were diagnosed with hypertension (or elevated blood pressure), the condition closely associated with high risks of serious cardiovascular problems like heart attack, stroke, and so on. At that, the mentioned risk increases substantially with age.

The experts tried to find proper explanations for the discovered issue of poor cardiovascular health of teenagers and sleep problems. It seems that poor sleep is closely linked to a lack of exercise, decreased appetite in the daytime and a tendency to have a snack at night causing poor nutrition and increased calorie consumption. All of the mentioned factors affect body mass, blood pressure and cholesterol levels, bringing to increased risks of cardiovascular diseases in today’s teenagers. Dr. Brian C. McCrindle, a senior researcher at the Hospital for Sick Children and one of the study leaders, underlines the importance of the links found by his colleagues: ‘When people think about cardiovascular risk, sleep doesn’t usually come up. These findings give more evidence that sleep is one of the things people should think about.’ He said that modern teenagers now have a great excuse to stay in bed for more than 7 hours every night.

Overall, the authors of the study aimed on finding the relationships between a chronic lack of sleep and teenagers’ cardiovascular health published the following information. Among all the participants of the study, 48 per cent of the teenagers had a problem of extra weight, accompanied with high cholesterol levels and high blood pressure. At that, among those teenagers who reported having a proper sleep every night and having a very good rest, only as much as 35 per cent had problems like either high body mass, or high cholesterol levels, or hypertension. At that, as the study has shown, more than a half of the teenagers reported about suffering from a chronic lack of sleep, restlessness, insomnia, inability to fall asleep, and other sleep disturbances.

Just 7 Hours Of Sleep For Teenagers Is Enough, A New Study Says

Many today’s moms are looking for an answer to the question, how much time sleep for teenagers can be enough? Earlier studies used to support the idea that due to very hard studies in schools and other realities of modern life, the present time’s teenagers need a lot of sleep. Some specialists in the matters related to teenagers and sleep are suggesting using not less than 9 hours a night, and for children between 7 and 12 not less than 11 hours of sleep is required. Sleep For TeenagresHowever, as the findings of a new study published recently in ¬†the Eastern Economics Journal have shown, the need in sleep of today’s teenagers is as much as seven hours only, and those of the young people who sleep too much can actually fall behind their school programs and their peers’ most common activities.

A group of scientists at Brigham Young University, Provo, Utah, monitored sleeping patterns and academic success of over 1720 American kids, secondary and primary school students. The main assessment was made on how many hours of the day they sleep, and what score they manage to achieve in standardized tests. It turned out that for primary school children aged below 10 sleeping time is 9 hours a night, for children aged between 11 and 12 it is 8 hours a night. 7 hours of sleep for teenagers between 12 and 17 turned out to be linked with a higher academic performance and good overall health. Eric Eide, one of the leaders of the research group, commented on the findings of his colleagues: ‘We’re not talking about sleep deprivation. The data simply says that seven hours is optimal at that age.’

At the same time, Brigham Young University scientists underline that not only such factors related to teenagers and sleep as sleep hours are linked to increased academic success. According to the findings, all schoolchildren aged between 12 and 17 can achieve better academic success and demonstrate better performance in case if their sleep is regular and of a good quality. Also, lower amounts of daily lie-ins are linked to a better performance in school, the scientists found out. Other factors that are linked to academic success of today’s teenagers include the level of their parents’ education, economic situation and psychological climate in the family, and many more.

According to the findings of another study carried out by the experts of the University of Chicago, those male teenagers and adults who sleep less than 5 hours a night for as long as 5 consequent nights have significantly lower levels of testosterone in the body compared to those men who sleep over 7 hours a night. It is a known fact that male hormone testosterone is closely linked to male libido and sexual power in men, therefore, the first drive of the men with less than 5 hours of sleep is put off their sexual life. Other important side effect of such decrease in sleep is decreased levels of energy. The experts found out that due to such sleep routine, the levels of testosterone in adults can fall down to the levels of a 15-year old teenager.
