Most replayed moment: Easy Steps to Reduce Inflammation and Slow Ageing | Professor Janet Lord

Chronic, low-grade inflammation—what scientists call 'inflammaging'—is emerging as one of the most critical drivers of aging and age-related disease, far beyond the acute inflammation we associate with injuries or infections. Professor Janet Lord reveals that this persistent, silent inflammation suppresses the immune system, accelerates muscle loss (sarcopenia), and increases vulnerability to infections and frailty in older adults. But the good news? Simple, science-backed habits—especially regular movement and resistance exercise—can directly counteract this process. Lord explains that even brief, frequent breaks from sitting can activate muscles to produce anti-inflammatory cytokines, effectively calming the body’s internal fire. The most powerful intervention? Consistently moving your body—whether through stair climbing, resistance training, or aerobic activity—acts as a natural regulator of immunity and inflammation, offering a practical, accessible way to extend healthy lifespan. The episode dismantles the myth that older adults should 'take it easy,' arguing instead that staying physically active—especially with resistance and stair-based movement—is not just beneficial but essential for maintaining strength, immune function, and vitality. Professor Lord’s bold advice: if you're helping an aging parent, don’t make life easier by removing stairs—make them climb them. It’s a small, cost-free intervention with profound long-term health returns.
