[quote=Anonymous][quote=Anonymous]And why would anyone bother with all this when people who want a later start time can just push their clock ahead 2 hours?[/quote] Shame DCUM has so many science deniers. [quote=Anonymous]More and more research showing circadian rhythms shift later in adolescents. The can't effectively go to sleep as early as we'd like for an early school start. But keep denying science; it suits you. https://pubmed.ncbi.nlm.nih.gov/36043490/ "It was shown that schoolchildren with [school start time] SST of 09:00 wake up at a later time on school days, sleep more, have less pronounced social jetlag and sleep loss, and higher academic performance than schoolchildren with SST of 08:00. As a result of logistic regression analysis, it was found that the frequency of the detection of food addiction is ~30% lower in schoolchildren with SST of 09:00 than in their peers with SST of 08:00." https://pubmed.ncbi.nlm.nih.gov/15930216/ "The results of this study demonstrated that current high school start times contribute to sleep deprivation among adolescents. Consistent with a delay in circadian sleep phase, students performed better later in the day than in the early morning. " https://pubmed.ncbi.nlm.nih.gov/35659022/ "Early school start times negatively affect sleep in adolescents as well, with poorer outcomes in their overall health, wellbeing, and performance." https://pubmed.ncbi.nlm.nih.gov/26545246/ "School start times were delayed 25-60 min, and correspondingly, total sleep time increased from 25 to 77 min per weeknight. Some studies revealed reduced daytime sleepiness, depression, caffeine use, tardiness to class, and trouble staying awake. Overall, the evidence supports recent non-experimental study findings and calls for policy that advocates for delayed school start time to improve sleep." [/quote][/quote]
