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. However, 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.
