Most of us assume that we are above the grubby world of biology, and that we can do what we want, at whatever time we choose. This assumption is wrong. Our biology is governed by a 24-hour biological (circadian) clock that advises us when it is the best time to sleep, eat, think, and undertake a myriad of other essential tasks. This daily internal adjustment allows us to function optimally in a dynamic world, “fine-tuning” our biology to the profound demands imposed by the 24-hour day.

Progress in understanding the fundamental nature of circadian biology has been astonishing, and certainly, this knowledge has added to our wonder and appreciation of the biological world. However, in parallel with this appreciation there has been an emerging realisation of the fundamental importance of circadian rhythms to our health and wellbeing.

In this talk Professor Foster will unpack the science of circadian rhythms, and how this new biology can be used by each of us to make more informed decisions to improve our lives.
