Think Thirsty - Episode 1, The Science and Psychology Behind Porn "Addiction"

In this episode of Think Thirsty, I chat about what the science actually says about the term “porn addiction.” We talk through how researchers distinguish between addiction and compulsion, what brain studies show about habit and reward, and how the Problematic Pornography Use Scale helps measure distress, control, and emotional coping. I break down how repetitive porn use can shape attention, arousal, and emotion regulation in everyday life. And we end by talking through psychological frameworks—like cognitive restructuring, behavioral activation, and reward reorientation—that can help us think more compassionately and curiously about our own patterns of desire.🔬 Sources MentionedDe Sousa, A., & Lodha, P.
