Good nature – the new science of how nature improves our health
Watch Baroness Katherine Willis CBE explore the relationship between nature and human health.
Strong scientific evidence indicates interacting with nature is linked to a whole host of positive physical and mental health outcomes. These include reducing harm (for example lower blood pressure and heart rate), building resilience (for example increased natural killer cells), and restoring capacities (for example faster rates of stress recovery).
Watch Professor Willis explain some of the current scientific knowledge and data gaps.
Her keynote speech was given at the CBA’s second Nature-First Economy event on 15 October 2025, held at St James’s Palace in London.
