14 FolgenOn the occasion of Daylight Awareness Week 2024 [https://daylight.academy/daylight-awareness-week-2024/] (28-31 October) and Halloween, Light O’Clock is partnering up with the Daylight Academy [https://daylight.academy/about/portrait/] to bring you an extra special episode that blends the science, the spooky, and the supernatural! Our host dives into the eerie mysteries of circadian rhythms, sleep and daylight with Prof. em. Anna Wirz-Justice, a pioneer in the field of chronobiology. Tune in to learn about the witching hour, twilight, the forbidden zone, sundowning and much more! This episode is supported by the Daylight Academy.

In today’s episode, we dive deep into the relationship between light, circadian rhythms and mental health with Prof. Daniel Smith from the University of Edinburgh. What role do light sensitivity and circadian rhythms play in bipolar disorder? How can we design studies to answer key questions in this area, and how can the involvement of patients ensure the success of a research study? Tune in to get the answers to these and many other questions about light, circadian rhythms and mental health.

Did you know that your body has many body clocks? Like instruments in an orchestra, they each have a specific role to play, but how do they stay in rhythm with each other? In today’s episode, Dr. Laura Kervezee dives deep into the different body clocks, who is the conductor that makes our body run in harmony, and what happens when the rhythm goes out of sync.

Are you an early bird or a night owl? Can you choose to be an early type? In this episode, Dr. Anna M. Biller from the Technical University of Munich explains what chronotype is, how it changes throughout the lifespan, what happens when your biological clock and your social clock are out of sync, and how can you measure your type. Listen to uncover the answers to these and many other fascinating questions about chronotype.

In today’s episode, we dive deep into the relationship between circadian rhythms and the sleep-wake cycle with Dr. Renske Lok from Stanford University. Are they different or the same? What other processes in the body regulate your sleep? Can you catch-up on lost sleep? How can you even know if you are sleep-deprived and need more sleep? Tune in to get the answers to these and many other questions on sleep and circadian rhythms.
