A large number of students are in the habit of staying up late preparing for the next day's exams.
They believe that burning the midnight oil is the most effective and economical way to study.
But they forget the fact that mind and body work together. They rarely do well on tests.
Their minds tend to go blank because they did not get sufficient sleep.
Poor physical conditions lower people's mental agility.
Quite a few office workers, too, are obliged to stay up late to get their work done.
They may have to meet a deadline. In the long run, however, this habit will cause some health problems.
Insomnia is just one of them. Besides, such workers will become less efficient.
They either go to work late or feel drowsy all day.
Either can damage their relationships with their boss or colleagues.
If they keep burning the midnight oil, they may get their fingers burned as well.
