After finishing a fascintating book called Why We Sleep by Prof. Matt Walker, I found myself trying to help a student get started on her exam revision in a visual arts cover lesson. She tells me she's had 4 hours sleep because she went to bed at midnight but had to set an alarm for 4am to finish an English task due that day. She isn't very hopeful that the revision will stick, and neither am I.

In this episode, I provide no final answers but enjoy having a good chat about the science of sleep, and how good sleep does seem to improve student outcomes.
