The propensity for sleep shifts later as puberty progresses. present analysis examines whether the circadian-dependent wake maintenance zone, or forbidden zone observed in evening just before habitual bedtime is more pronounced late to post-pubertal adolescents compared adults and may partly explain onset maturing adolescents. Forty four healthy late/post-pubertal (aged 14.3-17.8 years, 23 female) 44 30.8-45.8 21 participated an ultradian light/dark protocol 3 days cycling between 2-h periods (~20 lux) nap (~0 without external time cues. dim light melatonin (DLMO), a measure of circadian phase, was measured immediately by sampling saliva every 30 min light. Wrist actigraphs were used assess latency total during naps that occurred sleep/wake schedule. Sleep episodes grouped into bins relative individual DLMOs (28-56 naps/bin). well males females within each age group. Adolescents took significantly longer fall asleep 4 h window surrounding DLMO [2h t (50) = 2.13, p 0.04; 2 after (33) 3.25, 0.003]. also slept less than 4-h [2 t(51) -2.91, 0.01; -1.99, 0.05]. Adolescent adolescent [t (14) -2.24, 0.04]. Compared adults, showed greater difficulty falling maintaining around their DLMO, which usually occurs few hours onset.

Abstract The COVID-19 pandemic has seen a rise in anxiety and depression among adolescents. This study aimed to investigate the longitudinal associations between sleep mental health large sample of Australian adolescents examine whether healthy patterns were protective context pandemic. We used three waves control group data from Health4Life cluster-randomized trial (N = 2781, baseline M age 12.6, SD 0.51; 47% boys 1.4% ‘prefer not say’). Latent class growth analyses across 2 years period identified four trajectories depressive symptoms: low-stable (64.3%), average-increasing (19.2%), high-decreasing (7.1%), moderate-increasing (9.4%), symptom trajectories: (74.8%), (11.6%), (13.6%). compared on sociodemographic characteristics. Adolescents low-risk more likely be report shorter latency wake after onset, longer duration, less sleepiness, earlier chronotype. Where improved or worsened, changed same direction. subgroups uncovered two important findings: (1) majority maintained good habits ( trajectories), (2) with worsening also reported vice versa improving trajectories. These distinct would using mean-centred statistical approaches.

During lucid dreaming (LD), dreamers are aware of experiencing a dream and may consciously influence its content. This study used an online questionnaire to investigate the LD frequency applications in 193 adolescent athletes non-athletes (17.40 ± 2.09 years; 46% athletes, 54% controls). Given critical role that sleep plays health, development, performance, associations with various parameters were also explored. is prominent adolescents (67.4% experienced it at least once, 30.0% once month or more, 12.9% week), but similar terms uses between non-athletes. A higher proportion those who practiced sports/dance during reported improved waking self-efficacy (57.1%) over sport performance (42.9%). There was no indication chronotype preference nor be detrimental sleep. Athletes controls had durations, daytime sleepiness, disturbances frequency, quality. Despite, on average, meeting minimum recommendation guidelines for their age, relatively large did not attain sufficient sleep, particularly weeknights (47.4% 14-17 20.0% 18-21 years), suggesting restricted remains prevalent populations.
