Personal space shapes our daily lives more than we realise - from crowded commutes to open-plan offices and the subtle ways we signal when things feel “too close.” In this episode of Let’s Talk Health, host Natalie Cook speaks with Psychological Science Learning Facilitator Jenny Day to explore the science behind personal space, stress and why our brains react so strongly to proximity. 

Jenny breaks down how the brain interprets closeness, why our ancient threat systems activate in modern environments, and how anxiety, sensory overload and autonomy influence our comfort around others. Together, they discuss practical ways to recognise your own cues and approach these reactions with more understanding and self-kindness.
