In the dark: Body clocks and blindness
‘Our eyes are the window through which we make sense of the colours, people and objects around us. But scientists at Oxford University say they have another important role – setting our internal body clocks. When bright light enters the eye in the morning, it kick-starts the brain into generating a regular pattern of sleeping and waking. So what does this mean for people who can’t see anything at all? Smitha Mundasad reports from Oxford.’ (3 minute video).

Why do we Sleep? A TED Talk by Russell Foster
Russell Foster is a circadian neuroscientist: He studies the sleep cycles of the brain. And he asks: What do we know about sleep? Not a lot, it turns out, for something we do with one-third of our lives. In this talk, Foster shares three popular theories about why we sleep, busts some myths about how much sleep we need at different ages — and hints at some bold new uses of sleep as a predictor of mental health. (22 minute video)
Sleep – Freedom to Think
“Take control of your sleep,” says Professor Russell Foster CBE, leading neuroscientist and this year’s opening lecturer on the festival theme of the Speed of Life. Sleeping consumes a third of our lifetimes, but Professor Foster believes our sleeping hours are still not properly appreciated. His research shows how our bodies, honed by three million years of evolution, follow a natural clock and not the man-made one in daily use. He believes that all life on the planet has developed a 24-hour timing system which humans now use to fine-tune our rhythms.” Click this link to listen to Russell Foster talking about the importance of sleep at the BBC Free Thinking Festival (59 minute podcast): https://www.bbc.co.uk/sounds/play/b08hz9yw

How Sleep Science Explains Eye Disease and Mental Health
“Sleep disruption is so much more than the inconvenience of being able to sleep at the desired time — it is a global health disruption,” said Russell Foster, a professor of circadian neuroscience at the University of Oxford, speaking at Wired Health in London. (17 minute video)
The Science of Sleep: Melatonin to Neural Pathways
Russell Foster, Debra Skene and Stafford Lightman discuss the science of sleep in this video from The Royal Institution. Why do we need sleep and what are the physiological processes driving our circadian rhythm? When is our circadian clock disrupted and how does this affect our health? Cognitive neuroscientist Vincent Walsh chairs the debate. (52 minute video)
Light and the circadian rhythm: The key to a good night’s sleep?
We spend about a third of our lives asleep and cannot survive without it. But while scientists have long understood the importance of getting enough sleep, the key part played by light exposure can sometimes be overlooked.
