Sleep in on the weekend: good or bad thing?

It is completely fine to sleep in 1 or 2 extra hours to recuperate from missed hours of sleep during your work week. In fact, it increases your brain and body awareness. A 20-minute nap at 3 or 4 pm on a weekend can also be beneficial. But napping for more than two hours is likely to make it harder for you to fall asleep on Sunday night.
