It is no secret that many noble figures in the history practice polyphasic sleep. One of the significant ones is leonardo da vinci. This guy sleeps only 1.5-2 hours a day.

Others being Nikola Tesla, Thomas Jefferson, Thomas Edison, Sir Issac newton, Napoleon Bonaparte, Benjamin Franklin, Albert Einstein and many many more. Averagely having only around 3-4 hours sleep per day giving them more time to continue their research /work.

I wonder how they do it because scientist said that an average adult needs 7-8 hours sleep per day and anything less than that will harm your health. Why is it so that by just changing your sleeping habits will allow you to have more awake hours per day? In fact, you will not be able to enter deep sleep with such sleeping habits because one can only enter deep sleep after 1.5-2 hours of sleeping. And we all know that deep sleep IS the most important part of sleeping.

Wikipedia did cited such sleeping habits as a sleeping disorder. And patients are found to have less awareness, alert to surrounding and concentration.

So, how did polyphasic sleep allows a person to sleep less and still able to maintain a sustainable health while still retain the focus on their job? I have lots of doubts.

so your suggesting that we should increase the quality of the sleep, than the quantity?

but ur not suggesting ppl to skip sleep all few days just to get into REM sleep faster than usual right

so how did u find out how to cope with less sleep?

thanks, the way u use caps lock to highlight important words, hahahaha..... i can imagine how effective you are...
