Most replayed moment: Can you really boost your immune system? | Professor Daniel Davis

Professor Daniel Davis discusses why the popular concept of 'boosting' the immune system is scientifically misleading. He explains that the immune system is too complex and hidden to measure as simply 'strong' or 'weak,' and that most supplement and superfood claims lack evidence. The real ways to support immune health align with general healthy living — diet, exercise, and sleep — rather than any single quick fix.
