London: A new study reveals that teenagers suffer from erratic body clock issues because of early school timings, which affects their mood.
Scientists have claimed that changing when the school day begins can perk up a teen's mood, benefit their health and enhance their ability to learn.
With the beginning of puberty, a teenager's body clock is shifted to 11:00 p.m. as sleep time.
When schools starts early and are coupled with a teen's biological clock, the result is chronic sleep-deprivation, and low grades and health problems.
Academics also contest that whereas a late start in school increased potential of students, there is no such comparable research that proves early start is beneficial.
The research was published in journal Learning, Media and Technology.
