It has been suggested that schools should start later in the morning so that teenagers can get enough sleep. I agree with this proposal, although it would create some practical difficulties.
The strongest argument is biological. During adolescence, the body clock shifts, so teenagers naturally fall asleep later and need around nine hours of sleep. An early start forces many of them to wake before their bodies are ready, leaving them tired, irritable and unable to concentrate in the first lessons. Lack of sleep is linked to weaker memory, lower exam results, poor mental health and a higher risk of accidents for those who drive. Schools in the United States that moved their start times by an hour or so reported improved attendance, better grades and fewer cases of depression among their pupils. A later start would therefore benefit both learning and wellbeing.
Nevertheless, practical issues cannot be ignored. Many parents begin work early and rely on schools opening before their own working day, so children might be left unsupervised. A later finish time could interfere with sports practice, after-school jobs and homework, and might require changes to bus timetables, which would add costs for councils. Teachers, too, may find their own schedules disrupted. Some critics also argue that teenagers might simply stay up later instead of sleeping more, which would remove the advantage.
These objections can be addressed. Schools could introduce a modest delay of thirty to sixty minutes, offer supervised breakfast clubs for pupils who arrive early and plan transport accordingly. Parents and teachers should also encourage healthy habits, such as turning off screens before bedtime, so that the extra morning time is used effectively.
In conclusion, later start times match teenagers' biology and improve learning and health, and since the practical difficulties can be solved with planning, I strongly support the idea.
