Most of the time, I stay up late until midnight and do things that I want to complete. However, I get 7-8 hours of sleep a day.
My normal weekday routine is as follows: Wake up at 8am and go to work. Come back home for lunch at 12:30, take a 15-30 min. nap (not always, but makes my afternoon work go more smoothly), eat lunch, and then go back to work. (It is easy for me to eat lunch first and then nap, but I have heart burn and when I woke up I don't feel good.) Then I get back home at 5pm, take a 15 min. nap (I don't do that if I am not tired), eat dinner, and then stay until midnight to do some personal projects and assignments (3-4 hrs).
I heard that instead of staying late at night, it might be better to go to sleep early and woke up early in the morning (4-5) and do my personal projects.
Does the effect differ from person to person or is there a scientifically proven assumption that waking up early in the morning has an effect? How about the effect of doing physical exercises? Since I get tired after exercises, I don't exercise if I do have things to do later.
