Beebe D.W., Rose D., Amin R. Attention, learning, and arousal of experimentally sleep-restricted adolescents in a simulated classroom. In the same way, strengthening of the EEG connectivity may be driven by the increase of white matter volume and myelination process, which takes place during puberty [22]. Later School Start Time: The Impact of Sleep on Academic Performance The effects of sleep extension and sleep hygiene advice on sleep and depressive symptoms in adolescents: A randomized controlled trial. In this review of human and animal literature, we demonstrate that delayed sleep phase during puberty is likely a common phenomenon in mammals, not specific to human adolescents, and we provide insight into the mechanisms underlying this phenomenon. These data support involvement of a biological factor in the adolescent phase preference delay and indicate that our current understanding of adolescent sleep patterns may need revision. This notion is also supported by studies on neurodevelopmental trajectories in the adolescent brain. Moreover, morning rising time during school days leads to a large discrepancy between weekday and weekend sleep patterns as a direct consequence of rebound sleep on non-school days due to accumulated sleep debt during the week [48,49]. _____ hormones program the brain to behave in certain ways, whereas ________ hormones are thought to stimulate development of the secondary sex characteristics, Davis is interested in how puberty affects adjustment. Hasler B.P., Soehner A.M., Clark D.B. Therefore, intervening on sleep patterns could engender a cascade of positive outcomes on other areas of functioning. Furthermore, sleep loss in adolescents is likely to lead to increases in blood pressure [55,56] and high cardiometabolic risk [57]. Spectral power in the low electroencephalography (EEG) frequency band (~0.754.5 Hz) represents a sensitive marker of the homeostatic process, showing an increase dependent on previous waking period and a gradual decay throughout sleep episodes. Healthcare (Basel). Campbell I.G., Darchia N., Higgins L.M., Dykan I.V., Davis N.M., de Bie E., Feinberg I. Adolescent changes in homeostatic regulation of EEG activity in the delta and theta frequency bands during NREM sleep. Carissimi A., Dresch F., Martins A.C., Levandovski R.M., Adan A., Natale V., Martoni M., Hidalgo M.P. However, since the main biological changes in homeostatic and circadian processes covary during puberty, the studies described in the current paper concern the adolescent population. Unauthorized use of these marks is strictly prohibited. Recently, the study by Kelley and colleagues [123] went beyond the clinical recommendation that middle and high school should start later than 08:30 and examined possible additional benefits of moving starting times from 08:50 to 10:00 (1:10 h delay). Effects of school start times and technology use on teenagers sleep: 19992008. Sleepmore in Seattle: Later school start times are associated with more sleep and better performance in high school students. Pavlinac Dodig I, Lusic Kalcina L, Demirovic S, Pecotic R, Valic M, Dogas Z. Behav Sci (Basel). Epub 2015 Jul 16. It is noteworthy that nearly all studies used self-report instruments (questionnaire, survey, diaries) in evaluating the impact of changing school start times, except for a few studies using actigraphy [3,74,117,131] or polysomnography [3] to objectively measure sleep. Impact of insomnia on future functioning of adolescents. The delayed phase preference suggests that: school should begin later in the morning. Short M.A., Weber N., Reynolds C., Coussens S., Carskadon M.A. C) school should begin later in the morning. C) longitudinal design. Watson N.F., Martin J.L., Wise M.S., Carden K.A., Kirsch D.B., Kristo D.A., Malhotra R.K., Olson E.J., Ramar K., Rosen I.M. A large number of school systems all over the world have applied later start time programs as a policy change to reduce the imbalance between early waking time and adolescent sleep phase delay in order to address adverse outcomes intervening on the main external factor of sleep curtailment in this population. Additional research is certainly needed. 1-4 While most of the extant research focuses on the relationship between insomnia and mood disorders, other sleep disorders such as delayed sleep phase, inadequate total sleep duration and bedtime resistance in younger children may . Future studies should also investigate the effects on the well-known phenomenon of sleep inertia, occurring during the transition from sleep to wake [134,135]. Adam E.K., Snell E.K., Pendry P. Sleep timing and quantity in ecological and family context: A nationally representative time-diary study. 2023 Feb 28;12(3):383. doi: 10.3390/biology12030383. D. school should begin earlier in the morning. The adolescence sleep phase delay: causes, consequences and possible The site is secure. All the articles resulting from using these selection criteria and related to our focus were included. 2004 Jun;1021:276-91. doi: 10.1196/annals.1308.032. Delaying school start times can be a possible method to minimize the difficulty of staying awake during lessons by reducing the levels of daytime sleepiness. Campbell I.G., Higgins L.M., Trinidad J.M., Richardson P., Feinberg I. Another serious source of concern is represented by the elevated rate of suicidal ideation [66,67,68] or suicidal attempts [69] in sleep-deprived adolescents. C) school should begin later in the morning. Received 2020 Mar 11; Accepted 2020 Apr 7. D. Minges K.E., Redeker N.S. The phase delay gives the time delay in seconds experienced by each sinusoidal component of the input signal. Curcio G., Ferrara M., De Gennaro L. Sleep loss, learning capacity and academic performance. Physiologically, adolescents and young adults tend to have a delayed circadian preference, and are "night owls".12 This change occurs in association with puberty; more physically mature adolescents have a preference for later bedtimes and may have a lower homeostatic sleep drive, and consequently, are less sleepy at night.13-15 The . As a direct consequence of such sleep restriction, a multitude of adverse outcomes affects the quality of life of this population, especially compromising health and daytime functioning. The increase in longitudinally measured sleepiness across adolescence is related to the maturational decline in low-frequency EEG power. delayed-phase preference: the frequently seen tendency for adolescents and some others to perform better at tasks and to feel better later in the day, likely related to sleep-pattern changes of a physiologic nature. Furthermore, numerous studies were conducted without any follow-up protocols. Another critical issue about this literature refers to the exact quantification of how much time (minutes) school start should be delayed for ensuring the desired effect. Adolescents living the 24/7 lifestyle: Effects of caffeine and technology on sleep duration and daytime functioning. However, one study analyzing the benefitcost ratio suggested that shifting school start times represents a cost-effective strategy in the long term, resulting in substantial economic benefits relative to costs [95]. An official website of the United States government. The Role of Sleep on the Pathway to Substance Abuse in Teens. The delayed phase preference suggests that: school should begin later in the morning. Wahlstrom K., Dretzke B., Gordon M., Peterson K., Edwards K., Gdula J. However, delayed biological bedtime and early awakening due to school attendance inevitably result in a condition of chronic sleep debt in this population. HHS Vulnerability Disclosure, Help Shochat T., Cohen-Zion M., Tzischinsky O. Functional consequences of inadequate sleep in adolescents: A systematic review. Kubiszewski V., Fontaine R., Potard C., Gimenes G. Bullying, sleep/wake patterns and subjective sleep disorders: Findings from a cross-sectional survey. Taken together, most cross-sectional and longitudinal studies reported an increase in total minutes of sleep following later school start times [103]. [Google Scholar] 13. To determine whether biological processes may underlie a delay of phase preference in adolescents, 183 sixth-grade boys and 275 sixth-grade girls completed questionnaires for morningness/eveningness (M/E) and pubertal status. This behavior is known as the phase delay, and is in conflict with the students' morning school schedules. In search of lost sleep: Secular trends in the sleep time of school-aged children and adolescents. Sleep in adolescents and young adults. developmental-psychology; 18. Owens J., Group A.S.W. Sleep pattern, sleep homeostasis, and circadian rhythms in teenage students; Adolescent sleep loss and negative consequences on (a) mental and physical health, (b) learning abilities and academic performance, (c) risk-taking behavior; Experimental evidence on delayed school start time. Moreover, based on the available empirical evidence, we intend to propose a direction for future studies targeted to implement prevention or treatment programs by modifying sleep timing. Louzada F. Adolescent sleep: A major public health issue. Med. Baum K.T., Desai A., Field J., Miller L.E., Rausch J., Beebe D.W. Sleep restriction worsens mood and emotion regulation in adolescents. The paradox of adolescent health in the United States is that: adolescence is one of the healthiest periods in the life span, but nearly 1 in 15 adolescents has at least one disabling chronic disease. government site. His mother attributes his mood swings to being an adolescent. Determining the long-term effectiveness of intervention represents a crucial factor for a stable implementation of this policy shift. Adolescent 1 Flashcards - Cram.com Then, we also explore the relationship between adolescent sleep loss and principal domains of human functioning (mental and physical health, cognitive and behavioral performance). ; Supervision, L.D.G. Chapter 1 test Revised - Practice Test - Of all the - Studocu Some studies examined nocturnal melatonin patterns and found a global reduction in the basal levels of melatonin during the pubertal stage [6,7], in contrast to previous studies [8,9]. Almost all studies to date varied in their sample size and composition, ages of participants, and experimental design. Azadbakht L., Kelishadi R., Khodarahmi M., Qorbani M., Heshmat R., Motlagh M.E., Taslimi M., Ardalan G. The association of sleep duration and cardiometabolic risk factors in a national sample of children and adolescents: The CASPIAN III study. To introduce this primary issue, we briefly depict the most recent findings on current sleep condition in adolescents within a consolidated theoretical framework. J. In a recent meta-analysis [108], the length of delay was associated with the extension of sleep duration in a positive direction. Is insufficient quantity and quality of sleep a risk factor for neck, shoulder and low back pain? Allen R., Mirabile J. Self-reported sleep-wake patterns for students during the school year from two different senior high schools. . Tarokh L., Carskadon M.A., Achermann P. Dissipation of sleep pressure is stable across adolescence. Adolescents' preference for later school start times Randler C., Bilger S., Daz-Morales J.F. Sleep loss was further associated with unhealthy behavioral strategies [87], bullying [88], physical violence [63], and unsafe sexual activity [89]. . One study measured mental health indicators and reported fewer depressive symptoms in students with later start times than in the control group, although these differences were not significant [107]. The delayed phase preference suggests that: A. adolescents should not be taught sex education until high school.
