Why is it so hard to say no? Whether it’s at work, with family, or in everyday social situations, many of us find ourselves saying yes when we really want to say no, then paying the price later in stress, burnout, or resentment.

In this programme, the doctors explore the psychology behind our reluctance to turn things down, and how we can become more comfortable protecting our boundaries.

They’re joined by behavioural scientist and physician Dr Sunita Sah from Cornell University , whose research reveals how social pressure, guilt, and even professionalism can get in the way of a simple two-letter word. Together, they explore why we struggle to say no, and offer practical strategies to help us do it more often, and with confidence.
