Same with taking an afternoon nap. I've found that if post-lunch I work online and nap later than usual, I tend to wake up later at tea-time with a still sleepy and lethargic daze!

I have seen some people who go to bed very late and get up very late are not very active even though they have 7 hours of sleep. So a timely sleep is also very important. People who work in night shifts may sleep in the day time. Even then they are not very comfortable after getting up from sleep.
