Episode notes

Challenge refers to interventions that challenge the body mentally and physically in order to maintain muscle mass and promote bone health as we age.
Intermittent fasting is an example of a challenge that triggers an anti-inflammatory response and is associated with increased lifespan and healthspan in model organisms.
The repair side of things does not include sleep.
Mastering sleep hygiene is important due to the impact of electrical light, especially the blue spectrum, on the body's perception of starting the day.

Ian Sample talks to Dr David Furman, an expert on inflammation and ageing at Stanford University. He explains how chronic inflammation is affecting our health and how lifestyle choices can help us fight it. This episode has been updated from an earlier version which stated that dairy is a cause of inflammation. Current scientific evidence suggests dairy has a negligible to marginally positive impact on inflammation in humans.. Help support our independent journalism at theguardian.com/sciencepod
