Pre-thinking:

Imagine if you were locked in a bunker for a couple months stripped of your phone, laptop, watch, or any other time-telling machine and were forced to rely on your body clock. According to Jessa Gamble, the internal clock can provide us with the experience of full wakefulness when we retire our sense of day and night time.

Who is she:

Jessa Gamble is an award-winning writer who has devoted her research to the connection between sleep and global science. She was awarded a 2007 Science in Society journalism award from the Canadian Science Writers Association and has authored The Siesta and The Midnight Sun: How We Measure and Experience Time.

Why you should listen:

Gamble makes in excellent argument as to how our modernized urban 24 hour business day lives has changed our internal clock for the worse!

Discussion Questions:

  1. Every organism that has at least two, and sometimes one, cells has what chemical timer that helps distinguish between light changes?
  2. How much later do people wake up when stripped from their watch and light changes and how could that change the way you understand day and night?
  3. How does culture affect our sleeping patterns – think of Gamble’s explanation of sleeping during the summer and winter months in Arctic Canada.
  4. At what times would people sleep if they were using their ideal internal clocks?
  5. Would you ever be willing to give up a couple months to daylight and technology to live in a bunker to reset your internal clock? Think of all pros and cons and explain your answer.
