> In Matthew Walker’s book Why We Sleep: Unlocking the Power of Sleep and Dreams, the neuroscientist is blunt: “The shorter your sleep, the shorter your life span.”

I find it sad that people are still quoting this book. Many claims in this book have been debunked online[0]. The misinformation may even cause people to get too much sleep causing different kinds of issues.

As for me, this has caused me to come back with an impression of "we don't really know why we sleep." I wish there was a definitive source of information on this as popular as this book, but which is actually reputable. Now I just end up doubting my sleep patterns, waking up naturally and still being left unsure why I feel tired.
