I have been hacking my sleep to achieve the optimum sleeping period. Two months back when I started this experiment, I was sleeping almost 9 hrs per day. Today I am spending only 6.5 hrs per day on sleep. The gain of 2.5 hours per day is very big.
It started with reducing from 9 hours to 7.5 hours. It was tough, specially during the afternoon. Initially I had to take a quick nap (20 minutes) at my desk after lunch.
But then my body got used to it. A month & half later I took another giant step and reduced the duration to 6.5 hours. Again I went through the same cycle which involved similar noon naps. As of today, my sleep duration is only 6.5hrs per day *with out* any noon naps.
Another change I made w.r.t to my sleeping is to have fixed timings. Before I used to sleep anytime between 9pm-2am and get up anytime between 7am-9am. Now it is more fixed. Now I sleep strictly at 12am and wake up by 6am. My body is so used to it that I don’t need wake up alarms.
The standard side effects of reduced sleep are loss of weight, irritation, low concentration etc. As of now I don’t see any side effects (or I don’t know). In fact my other experiment of “Put on weight” is also giving positive results :)
The ultimate plan is to reduce the sleep duration to 6 hours. But I am still not sure if my body can take it. I am planning to go with 6.5 hours for six more months and then take my next step.
