Everything else feels right or not in this life....sleep does  .
It can never be compromised for anything.

Personally , I take 'beauty sleep' of 8 hours daily ...no matter what.. 

So How many hours sleep is really needed, or How many hours you sleep???

As far as I know, our body needs 8 hours of sleep a day, but personally me I only slept 5 - 6 hours a day because of my online jobs at night, then I'm so sleepy in my work at morning, so sad but I need to this for my family.

Power naps in between are effective in regaining energy. Being a student i have enough time after noon to take such naps. Maybe you can take such naps at night in between your "Online Jobs"  

Yup! power naps is very effective but I can't take naps at night it's because it will not be a nap anymore instead I will sleep continuously lol
