5. Mid-day naps
We all used to hate the naps we had to take as babies, but these naps are vital for a fully grown adult. Taking a nap in the middle of the day is known to increase the efficiency of the human mind. It also refreshes the mind, thus allowing you to work even better and contain more knowledge. The best time to take a nap is around 3 PM, or you could simply take a nap after a workout session.
