Well, the second biggest reason why we cannot have enough sleep is studying. Do you study a lot?
No, I don't.
That is what I thought. I am busy making the video game every day, but I make time to study also.
So sometimes I stay up late for study.
You are the one who cannot sleep enough.
Well, as we described on the page of "Efficacy of sleep", what we have to care is to keep regular hours.
That helps our academic results better.
Yes, of course.
The morning and night time is the best time to study.
In the early morning, your brains are the clearest in the day.In the early morning, your brains are just after taking a rest.
So it is like a white campus. It can absorb any information rapidly.
At night you will sleep after studying. So your brain can marshal the things you learned while sleeping.
Both times have the good points. But if you study at night every day, it might disturb your sleeping hours.
Because you cannot have enough sleep. Then even though you study hard at night, your brain cannot marshal the things you study.
And as we explained on the page of "Efficacy of sleep", you should stop studying by 11:00pm. After that, even though you study hard, it is not so efficient.
So what we need is to keep regular hours and study in the early morning and at night before 11:00pm.
