A video clip that caught my attention

Title of this video clip: Early Birds vs Night Owls

Content of the video clip: This video clip compares the difference between humans who are early birds and humans who are night owls.  The video provides reasons for the difference of sleep patterns  in different humans.  It also lists the advantages and disadvantages of being a night owl or early bird.

What I have learnt from this video clip:
  • I have learnt that night owls are not always at a disadvantage.→Night owls have higher cognitive ability than early birds and tend to be risk-takers, leading to more opportunities and much more financial gain.
  • I have learnt that the brain of early birds have more white matter in their brains as compared to night owls.→Since the white matter helps neurons communicate, lesser white matter means there are lesser pathways for feel good hormones such as Serotonin and Dopamine in the brains of night owls.  As such, night owls experience social jetlag, where they feel that they are in a different time zone altogether.
  • I have learnt that our sleep patterns can be genetically passed down from our ancestors.→So if our ancestors were night owls, we would most likely be night owls.  Whereas if our ancestors were early birds, we would most likely be early birds too.
