Power-napper par excellence
That’s me. Since my college days I have a habit of sleeping for an hour in the afternoon usually just after lunch. We usually used to have our lecture from 1 to 5 in the afternoon and since attendance was not mandatory for most of the courses I would skip one or two (at least) and sleep nicely.
However things changed when I left the nice comfy world of college to earn my livelihood. Was it acceptable to sleep in office? What would colleagues think? What would my boss think? But I was lucky enough to always end up in liberal-attitude projects and understanding bosses and so never had to really confront those questions. So my power-napping still continues. The duration has come down to 20-30 minutes but not the effectiveness.
Again things changed when I had to lead a project. When you are a team member you do not have to think much about being a role model or setting an example. You can go where your heart takes you. But is it nice to sleep when you the project leader? Again to my happiness I realised that people usually do not care much about these things. As long as you do the work efficiently, help everybody out and do well in your formal and informal responsibilities everybody looks up to you. In fact catching a few winks makes you look like somewhat of a “rebel” and add to your coolness quotient, an unintentional but not undesirable side-effect 
Power-napping leaves me fresh and releases new reserves of energy. It improves my mood and concentration span. And I have managed to regulate the nap periods to 20-30 minutes quite consistently and therefore it does not have any significant impact on my schedule. So my dear friends if you feel very drowsy at work I recommend you try this very effective technique, I am sure it will bolster your energy by at least a couple of hours.
