I really don&#x27;t think it&#x27;s just a legend. The linked article and Wikipedia (<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Segmented_sleep" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Segmented_sleep</a>) give enough evidence that it seems unlikely to be a complete myth.<p>And saying &quot;I hate waking up in the middle of the night&quot; doesn&#x27;t really have much to do with this. If you consistently slept for 12 hours a night, you might find it a lot easier and more pleasant to get up in the middle, and that&#x27;s exactly what one of the studies in the Wikipedia article showed.<p>And as anecdotal evidence, even a few people in this 2-hours-old comment section say they&#x27;ve tried it with good results.
