The Circadian Rhythm
Nice Genes!
Introduction
This chapter mentions the Genetics Unzipped Podcast's recent episode about circadian rhythms and transitions to a discussion about recurring dreams and spooky nightmares.
Challenging our assumptions about sleep
Sleep is essential to our lives, but our perception of how it functions in our non-waking life is not always well understood. So in the mires of our busy daily lives do we overlook sleep by seeing it as a means of refilling our energy for a productive day? By questioning this assumption, one term rolls from out of the haze: The ‘Circadian Rhythm’.
Dr. Kaylee Byers speaks with Dr. Hiroki Ueda from the University of Tokyo in the Faculty of Medicine on demystifying the links between our sleep and genomics. Then neuroscientist Dr. Andrew Coogan shares the connection between sleep and ADHD. Finally, we hear from Dr. Ueda and Dr. Hiroshi Ono, from Hitotsubashi University Business School, on how their homeland of Japan is reckoning with an off-balance relationship with sleep and work.
