In this bonus episode of Let’s Talk Health, host Natalie Cook speaks with psychology learning facilitator Jenny Day about how COVID-19 has reshaped our sense of personal space. While crowded trains and busy offices once felt normal, the pandemic triggered a global shift in how close we’re comfortable getting to others. Jenny explains why personal space boundaries expanded, how pathogen awareness influences our reactions, and why many people still instinctively step back in public settings.

Together, they explore the psychological impact of lockdowns, the role of threat perception, and how factors like climate, culture and disease history shape comfort zones around the world. It’s a fascinating look at how our ancient survival instincts collided with a modern pandemic - and why closeness still feels different today.

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.

• What “personal space” really means in psychological science
• How the brain processes proximity, threat and safety
• Why crowded trains, busy cities and open-plan offices feel overwhelming
• How the amygdala influences our reactions to closeness
• The link between anxiety, hypervigilance and larger personal space boundaries
• Why sensory overload is more common in modern environments
• How autonomy and control shape comfort levels in social spaces
• Everyday cues we use to signal “I need more space”
• Why headphones have become a universal social boundary marker
• Practical ways to understand your reactions and support your well-being

In this bonus episode of Let’s Talk Health, host Natalie Cook speaks with Associate Professor Rachel Ambagtsheer about how social media shapes the way we think about ageing. Together, they explore how beauty standards, image-based culture and “anti-ageing” messaging influence our expectations of what getting older should look like.

Rachel explains why the cosmetics industry often reinforces ageist ideas, how constant exposure to curated images affects self-perception, and why younger generations may be absorbing narrow ideas of what is “normal”.

In this bonus episode of Let’s Talk Health, host Natalie Cook speaks with Tim Trevail to explore why pain is more about protection than damage. Together, they unpack how the brain interprets pain, why context matters, and what it really means when something hurts - from stubbing your toe to recovering from injury.

Using relatable examples, Tim explains how factors like childhood learning, fear, and even social settings influence how we feel pain. He shares how athletes train their brains to tolerate discomfort, why past injuries can trigger false alarms, and how understanding the mind–body connection can help anyone manage pain more confidently and move freely again.
