To get up early to study or to stay up late to study?That is the question that puzzles most English learners.

A recent study by Dr.David Johnson discovered that late bedtimes led to lower grades.“Late bedtimes during weekdays and weekends,catch-up sleep on wekends and more daytime sleepiness badly influence students’ English study performance.They forget the new words more easily and have difficulty talking about their thoughts in English clearly.”

However,another study by Dr.Ali on Biocenter.com showed there is no connection between a student’s sleep habit and his study performance.“We found that different sleeping habits do not influence the performance of students in their English study,”Ali said.

Emily Jane,a college student,said she prefers to study differently depending on when the English test is.Normally,she only gets up early to study if she has an exam in the morning.She’ll arrive at school around 6:30 a.m.and study for her exam.If the test is a few days away,Jane said she will stay up later.

“Personally,I think that creativity or projects come at night,”Kyle said.Kyle does quite well in English.During the week,he will usually get up early to read texts aloud around 6 a.m.and be at school by 7 a.m.After that,he will stay up to do English reading until 1 or 2 a.m.On the weekends,he will sleep until about 1 p.m.

It is impossible to know for sure if it is better to stay up late and study or to wake up early to do so.But doctors advised students to avoid all-nighters because they won’t help as much as students think.
