My guest today, Russell Foster, has the grand title of Professor of Circadian Neuroscience at Oxford University, which is the science speak way of saying he is he's obsessed with clocks . - not the ticking type, but rather our biological clocks and the rhythm rhythms of life. More specifically, he studies the way light controls our internal clocks and circadian rhythms , and works to understand how light and dark affect our well-being. , everything from jetlag jet lag to serious mental health problems. Russell had to fight against strong oppositions opposition from eye experts when he discovered a new way in which animals can detect light. He's written a number of books explaining how these biological clocks control our and other animals' daily lives. Russell, welcome to the Life Scientific.

Delighted to be here, Jim.

Now, does our biological makeup mean it's difficult for us to cope with our 24/7 society?

Well, yes, . We carry with a set us sort of three and a half 3. 5 billion years of evolutionary baggage and buried it embedded within our genome our are the instructions of an the internal clock. It's actually , essentially providing us with a the representation of a day within. And every aspect of our physiology is being fine-tuned to the varying demands of activity and rest. And we can't easily work against that embedded programme.
