I’m joined by Russell Foster CBE, one of the most prominent sleep experts globally and professor of circadian neuroscience at Oxford University. Russell’s research centres around sleep, the body clock and how the two profoundly affect our biology and our overall health and wellbeing. We discuss: Why sleep is important and how much we really need The link between cravings, hunger, and sleep Tools for improving sleep quality Why stress may be at the root of your sleep difficulties How fine-tuning your internal body clock supports optimal health Each week I unpack a wellness trend with GP Gemma Newman. This week on Fact or Fad we’re looking at matcha versus coffee, where should we get our caffeine from.
