Biopsychology – Biological Rhythms

  • Description

About this Course

About the Course

In this course, Dr Halstead (University College London) explores biological rhythms. In the first lecture, we think about the three main types of biological rhythm: infradian, circadian and ultradian. In the second lecture, we think in more detail about circadian rhythms, specifically the sleep-wake cycle. In the third lecture, we think in more detail about infradian and ultradian rhythms, specifically the sleep cycle and the menstrual cycle. Next, we think about the impact of rotating shift work on circadian rhythms, reviewing Czeisler and colleagues’ 1982 study. In the fifth and final lecture, we think about some key ways of reducing the impact of jet lag on circadian rhythms.
