Due to the last unrest in Tunisia, studies and work has permanently stopped for around two weeks. I was following politics and life (study/work/house work) was the last thing to think about.

So I was sleeping when I needed it and waking up, when I just wake up. I've found during that period that I'm following a poly-phasic sleep instead of one phase sleep.

This can be caused by staying late (until 4-5 A.M.) on Facebook. However I let my body naturally wake and sleep. It organised itself, by itself.

- The day begin at 9:00-10:00 [around 4 hours sleep]

-> Feel good and fresh; have a considerable concentration; however my strength and concentration quickly drop at 2:00-3:00 PM

- So, I get back and sleep at 2:00PM-3:00PM [around 2,5 hours sleep]

-> Feels good too, and I can stand up to 4 or 5 A.M. with a considerable strength and concentration. From 1:00 A.M to 4:00 A.M, I have a considerable concentration and spirit.

So, I sleep 6.5 hours Vs. 7 hours, where is really the difference?

I found out that the difference is huge!

1. When I wake up at 10:00 I spend much less time at breakfast, I then quickly jump to do something. I don't feel I need to waste time. -30 min. gained-

2. I need a rest in the half of the day. Generally, I spend 1-2 hours in front of T.V or Internet. Now I sleep instead. So that's time earned. -2:00 hours gained-

3. I also need a rest before starting my night, generally an hours. Now I don't need it. I just woke up. -1:00 hour gained-

4. Finally, when it's 1:00 A.M, I find that I get back my breath. May be because it's calm and dark. There is no distractions.

So there is:

- Improvements in productivity and concentration

- I feel always fresh and no exhaustion

- I saved 3:30 hours
