On a typical school night, they spend over 2 hours on homework. The more stress a teen feels, the more likely they are to spend even more time on homework.<\/p>\n<p><span style=\"color: #21738a;\"><strong>What are the causes of stress for high school students?<\/strong><\/span><\/p>\n<p>Grades\/test scores and homework are overwhelmingly the top two causes of stress for all teenagers.

More than three-fourths (79%) get 7 hours of sleep or less on a typical school night. Only about one in five teens are getting 8 hours of sleep or more. 43% of teens are going to bed at 11 p.m. or later and about one-third (33%) of these same teens are waking up at 6 a.m. or earlier. The more stressed a teen feels, the more likely they are to get less sleep, go to bed later and wake up earlier. They are also more likely to have trouble going to sleep and staying asleep \u2013 more often than their less-stressed peers.<\/p>\n<p><span style=\"color: #21738a;\"><strong>Methodology<\/strong><\/span><\/p>\n<p>The online survey was fielded between 9\/27\/18 and 9\/29\/18 with 1,004 teenagers across the United States. Lucid, a global company with industry-leading automated sampling, provided the sample. All respondents were between the ages of 13 and 19 and currently attending high school. About half of the respondents were seniors and three-quarters were 16 years of age or older.

They showed that students with higher grades reported more total sleep, earlier bedtimes on school nights and reduced weekend delays of sleep schedules than students with lower grades. These data of better performance as a consequence of \u201chygienic\u201d sleep patterns were confirmed by several studies indicating a poorer school achievement, a greater tendency to fall asleep in school, more difficulties in concentration and in focusing attention in students with an evening circadian typology, earlier school starting times and a mild delayed sleep phase syndrome.<\/em><\/p>\n<p><em>\u2026 regardless of the theoretical framework adopted (dual process hypothesis or sequential processing hypothesis), both REM and NREM sleep seem necessary for learning and memory: thus, for an efficient consolidation of both (declarative) knowledge and (procedural) skills, the worst risk is sleep loss or fragmentation. Moreover, it was shown that an increasing daytime sleepiness, as a consequence of poor sleep quality, can seriously impair students\u2019 cognitive functioning and behavioral performance<\/em>.<\/p>\n<p>Source: Giuseppe, C., Ferrara, M., and De Gennaro, L.

We find that the group that get the most abundant sleep group (sleep early and wake up early group) are less likely (35%) to get stressed out than they don\u2019t, while the group that get the least amount of sleep (sleep late and wake up early) has significantly more chance (136%) to get stressed out than others. This group spend much more time working on the homework than unstressed group (2.72 hrs. vs 1.9928 hrs.). However, they don\u2019t get better grades. Yes. <em>They sacrifice the sleep time, spend extra amount of time on homework, bear extra stress but they don\u2019t get better grades. <\/em><\/p>\n<p>Bad sleep habits (sleep late) also reduce the quality of sleep and bring issues. The \u201cSleep Late &amp; Wake Up Late\u201d group, although they don\u2019t wake up early, still the majority of them feel that they don\u2019t get enough sleep (74.8% comparing to 49.5% of sleep early and wake up early group, a group that get similar amount of sleep time). Sleeping issues and bad sleep quality reduce the chances of getting good grades. The group who always have trouble falling asleep is 92% more likely to get C or below than they get As.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How many hours a week do teenagers spend on homework?
