Dr Rangan Chatterjee: GP & Author
About this episode

Sleep is one of the most important pillars of health. Our bodies and our brains are designed to function during the day and rest at night.


Feel Better Live More Bitesize is my new weekly podcast for your mind, body and heart. Each week I’ll be featuring inspirational stories and practical tips from some of my former guests.


This week’s guest is award-winning journalist, Linda Geddes.


Circadian rhythms are 24-hour cycles that are kept in time by light and dark cycles. These rhythms can become disrupted by changing our exposure to light which can affect our sleep and make us feel sluggish during the day.


Exposure to bright light after sunset is a modern phenomenon. Darkness is a signal to our bodies that it’s time to rest and access to bright light and screens at night disrupts these signals.


There are simple things that we can do to help reset our circadian rhythms. Linda shares the findings of her own experiment of getting rid of light at night in her own home.


Finally, she gives her tips on what we can all do to get more light into our days and darken our nights.


Access to sunlight, even in winter, is crucial for living a happy and fulfilling life. I hope you feel inspired to get outside!
