Early School Timings Affect Teenagers’ Performance, Lead to Obesity, Depression: Study

Early school timings are not good for teenagers and may hamper their performance in studies owing to sleep inadequacy, says a study.

As per the norm, children require about nine hours of sleep during adolescence when their growth is very high and older kids tend to stay awake for longer hours than the younger ones, the study confirmed.

“This is one of the few studies that has tracked sleep behaviour and circadian rhythms over the course of up to two-and-a-half years in the same adolescents,” said lead author Stephanie Crowley from the Rush University Medical Center, Chicago.

The impact of inadequate sleep will result in poor academic performance, frequent mood disturbance, depression, obesity and feeling drowsy during the day. It also warns that those driving may lead to negligence and cause accidents, especially among the older teenagers.

The research studied 56 volunteers, aged 15 or 16, who participated in the research and found that weekday sleep time continued to shrink with age for all of them.

Even those typical kids who go to bed sharp at 8 pm or 9 pm, moved to a later sleep/wake cycle with ageing, said the study, which has been published in the journal PLoS ONE.
