A switch to permanent daylight saving time will undo any positive effects on sleep of delaying school start times, according to researchers.
Delaying school times has been a contentious issue in North America and Europe with proponents arguing that such a postponement would enable teenagers, who typically go to bed later, to get the recommended amount of sleep, whilst opponents point to the logistical problems that would arise from such a change.
DST, the practice of setting the clocks forward one hour from standard time (ST) during the summer months in order to make better use of natural daylight, is also a divisive issue
In March, the European parliament voted to stop changing the clocks, with European Union member states required to decide whether to stay on permanent DST or permanent ST by 2021.
