Cours de conversation en anglais : Wednesday 30th and Thursday 31st August 2017


When do you feel sleepy?

Alice and Neil discuss circadian rhythms – the so-called body clock that influences an organism’s daily cycle of physical, mental and behavioural changes – And what shift workers can do to help.

This week’s question

What does the word ‘circadian’ mean? Is it…

  1. a) around a day?
  2. b) every day?

You’ll hear the answer at the end of the programme.
