Has something to do with sleep cycles. But don't worry about what is written. Just give it a try and see how much you naturally sleep for and when you wake up and go from there. This can be as simple as just laying your head down on a desk with an eye patch and ear plugs. Airline tarmack type ear muffs also work well for this and completely block out most noise. Everyone is different. I don't care much for what has been written about this I just experiment and have found what works for me. I have been doing this from way before there were even things written or it was something that was even considered a strategy. To me it just made sense. I don't really care what others do or whether they think it's good or bad.
