We all know that sleep can have a huge impact on our quality of life. But how does sleep actually work, and what can we do to improve it? In this episode I sat down with world-renowned sleep and circadian rhythm expert Professor Russell Foster. Russell has recently published a book called ‘Lifetime’, which explores how our circadian system underpins our overall health and this new science of the body clock can help us have better sleep, better health, and better cognitive function. In the conversation we talk about exactly how our body clocks work, and what we can do to make sure that we are keeping our internal clocks on track through light, temperature and stress reduction. He also debunks some common myths about sleep and gives his top tips for making sure we get enough rest so we can function at our best.

Join Russell Foster, a professor of circadian neuroscience and author of 'Life Time,' as he unravels the secrets of your body's internal clock. Discover how light exposure affects your physical and mental health, and learn why blue light could be ruining your sleep. Foster highlights the serious health risks of night shifts and shares practical tips for optimizing your sleep schedule based on your chronotype. Plus, find out how circadian rhythms impact immune function and medication timing for better health!

Professor Russell Foster, one of the world's foremost experts on circadian rhythms and sleep, discusses various topics on optimizing sleep. Highlights include the impact of sleeping arrangements on relationships, the accuracy and concerns of sleep trackers, the illusion of human success, and the effects of light exposure on sleep and mental health. The podcast also covers sleep aids, the role of light in setting the body's clock, the effects of melatonin and aging on sleep, and the importance of restful sleep.

Sleep: How Do We Get More? Guests include Pam DeYoung, a lab coordinator, Dr. Brady Riedner, a sleep researcher, and Prof. Russell Foster, a circadian scientist. Not sleeping enough affects our behavior. A sleepy brain is less efficient and slower. Circadian rhythm affects sleep. Melatonin helps regulate our internal clock. Blue light disrupts sleep. Consistent bedtime routines and a sleep-friendly environment improve sleep quality.

In today’s discussion, Russell Foster, a Professor of Circadian Neuroscience at Oxford University, uncovers how light exposure affects our health and mood. He emphasizes the importance of morning light for regulating our biological clock. Foster explains how natural light can enhance mental well-being and improve sleep patterns, presenting light therapy as a promising alternative to medication for mood disorders. The conversation also touches on the detrimental effects of evening screens and the need to align our routines with nature's light cycles for optimal health.

The tired brain remembers negative experiences but forgets the positive ones. Is there a more powerful statement in favour of going to bed earlier and prioritising our sleep? Modern life has seen us push into the night, staying up later and extending our social and work lives around the clock. But this, says today’s guest, goes against what our bodies are wired to do. Russell Foster is Professor of Circadian Neuroscience at Oxford University and author of the fantastic new book, Life Time: The New Science Of The Body Clock And How It Can Revolutionise Your Sleep and Health. Russell explains that living out of sync with our circadian rhythms doesn’t just lead to sleep disruption and tiredness. The further we stray from them, the more we become vulnerable to chronic conditions such as obesity, type 2 diabetes, heart disease, cancer, suppressed immunity, dementia and mental illness. But he’s not here to scare us – rather share the strategies that we can all use to get back on track. During this compelling conversation, we cover the science behind exposure to natural daylight at the right times. We talk chronotypes – and if there’s anything you can do to change being a lark or an owl. Russell explains the dangerous phenomenon of ‘microsleeps’ and why 4am is the most dangerous time to be on the roads. And we cover the unique problems faced by night-shift workers and new parents, including what they, their families and employers can do to mitigate their health and safety. We also chat about the value of sleep trackers and blue-blocking glasses. Russell busts the myth that we all need eight hours’ sleep or that you mustn’t read a Kindle before bed. And he reveals the best time of day for sex (clue: it’s different depending on whether you want to conceive or relax). And for all those insomniacs who go to sleep fine but wake during the night? There’s some wisdom towards the end of our conversation that you’ll want to hear! This is a fact-filled episode, full of fascinating insights.

Every moment of the day tiny biological clocks are ticking throughout the body, but Russell Foster, world-renowned expert in circadian neuroscience, warns that modern life is playing havoc with these ancient and delicate mechanisms. In his latest book, Life Time: The New Science Of The Body Clock And How It Can Revolutionise Your Sleep and Health, Professor Foster reveals how this essential part of our biology works. He tells Tom Sutcliffe how new understandings about our daily routines could help reset how we live and sleep.ViSiBLE is a professional theatre company dedicated to creating new and provocative works, with and about older people. Its latest performance, Five Characters in Search of a Good Night's Sleep, is at the Southwark Playhouse until 21st May. ViSiBLE’s founder, the playwright Sonja Linden, says the new piece was inspired by the experiences of the actors who as they’ve aged have found sleep more elusive and sleep-inducing techniques more desperate.

Her research focuses on ideas about sleep and insomnia, and how they’ve been represented in the visual culture of twentieth century and contemporary China. From the images of ‘national awakening’ in the early years of the Republic and the always-alert workers of the Cultural Revolution to the cities that never sleep today – sleep deprivation has become part of life in China.Producer: Katy HickmanPhoto Image: 'Five Characters in Search of a Good Night's Sleep' (credit: Bessell Photography)

The assault on our sleep really only began in earnest 75 years ago as the world became flooded with light, stimuli, shift work, and birthed the concept of a 24/7 world. Today, we're wired and tired, overworked and under rested. This is not news to you, but what might be When we think of high-risk jobs, we often think of underwater welders, fishing boat crew, and oil rig workers. But did you know that all shift work is also high risk? You're unlikely to have physical risks, but the metabolic, mental health, impaired driving ability, and even cancer risks are sky high.  Here's what happens when we don't sleep:  Ghrelin, the hunger hormone goes up Blood glucose and metabolic health suffers  Cardiovascular risk shoots way up Risk of neurodegenerative illness skyrockets  Links Russell’s Book ABOUT RUSSELL FOSTER - Russell Foster is a British professor of circadian neuroscience at Oxford University and the director of the Sleep and Circadian Neuroscience Institute (SCNi). He is known for his discovery of non-rod, non-cone ocular photoreceptors that regulate the body’s internal clock. He has received numerous awards for his research, including the Zoological Society scientific medal and the CBE (Commander of the Order of the British Empire). He is the author of Time Line: Your Body Clock and Its Essential Roles in Good Health and Sleep.

In today’s world, we increasingly live our lives late into the night. Whether it's work obligations, socializing, or being glued to a screen, we ignore the sun's rise and fall. But most of us are unaware that a clock is ticking away inside us. It uses light to keep time and tells us when to sleep and eat. Should we listen? Or is this biological clock simply a relic from a past time?In today’s episode, Jonathan speaks to a leading authority to unravel the latest science that reveals that this body clock, or circadian rhythm, has a dramatic impact on our health, weight, and mental wellbeing: Russell Foster is an Oxford University scientist who has dedicated his life to studying circadian rhythms.

Professor Russell Foster, Director of the Sleep and Circadian Neuroscience Institute at Oxford, shares top sleep tips such as finding relaxation instead of agonizing awake at night and sleeping on big decisions. He also discusses the impact of light on our chronotype and the power of sleep in problem-solving and breakthroughs.

Every second of the day, tiny biological clocks are ticking throughout your body, from the neural pathways of your brain down to your very cells. But modern life is disrupting this ancient and delicate mechanism in ways we are only just beginning to understand. Artificial light, jet lag, smartphones, air pollution and out-of-sync work-and-meal routines are conspiring to push us out of joint. This is not only exacerbating mental health issues such as depression and fatigue, but according to new studies, is also increasing the risk of obesity, heart disease, dementia and even cancer. Professor Russell Foster is a world-leading expert on circadian neuroscience and his new book, Life Time, looks at how we can better understand and harness the science of rhythm and our own biology.
