Effects of Sleeping Late

Well this may seem a little hypocritical but recently i've been staying up late. Of course I can justify that I can, in fact, afford to sleep later because I don't need to get up early (for your information, i'm on a holiday break now). Consequently, I've been staying awake until 2am in the morning, then I sleep for around 8 hours and wake up at 10am. I do this intentionally, not because I cannot sleep but because I'm busy on the computer. (If you are having difficulty falling asleep, you might want to take a look at this article on how to fall asleep quickly)

Anyway, I noticed a few peculiar things that I'd like to share. For one, even though I was getting the same amount of sleep, I felt more tired than I normally did. I attribute this to the decreasing quality of sleep as the day progresses, mainly because the ambient noise and light levels are significantly higher in the morning. In fact, I noticed that towards the end of my sleep (8am onwards) I constantly slip in and out of light sleep. I would awaken groggily and feel extremely drowzy and fall asleep a few minutes later only to awaken again within the hour.

I think that this could be aggravated by the fact that the latter part of our sleep is deep sleep, where body regeneration takes place. Having this interrupted would definitely affect our energy levels.

In conclusion, sleeping late could result in a poorer quality of sleep, as I have experienced myself. Maybe it would be wiser to just tuck in and leave tomorrow's work and worries for tomorrow, instead of staying up and risking your well being.
