Rewiring Your Brain for Better Mental Health: How Small Actions Can Transform Your Health with Dr Camilla Nord #543

Apr 1, 2025 2h 20m 20 insights
Have you ever wondered why the same traumatic experience affects different people in completely different ways? Or why finding pleasure in life is so fundamental to our mental wellbeing? To answer these questions and a whole host more, I'm joined this week by Dr Camilla Nord. Camilla leads the Mental Health Neuroscience Lab at the University of Cambridge and is author of the best-selling book, The Balanced Brain: The Science of Mental Health. In this fascinating conversation, we explore: How everything that impacts our mental health ultimately works through the brain, and why we often artificially separate 'mind' from 'brain' and 'mental' from 'physical' health Why pleasure is so fundamental to mental wellbeing that a loss of it is a core symptom of depression, and how activities like social laughter can boost mood by releasing natural opioids The fascinating overlap between chronic pain and depression circuits in the brain – revealing why experiencing one increases your risk of developing the other How motivation varies throughout the day based on our individual body clocks, and why morning people and night owls have different energy patterns Interoception – our internal body awareness – and how practices like meditation, yoga and body scanning can enhance this crucial sense Why the placebo effect is so powerful and how a doctor's communication style can significantly impact treatment outcomes Throughout the conversation, Camilla emphasises that there is no one size fits all approach and that it’s the small, consistent actions that ultimately end up transforming our lives.   Support the podcast and enjoy Ad-Free episodes.

Actionable Insights

1. Prioritize Pleasure for Mental Health

Do not deprive yourself of everything you love in pursuit of optimized health, as this often does not lead to the best mental health. Instead, actively seek out and prioritize doing things you genuinely love, as there is an inherent benefit for your mental health.

2. Start Small to Build Habits

To overcome apathy and build motivation, make the initial cost of an activity very small (e.g., 5 minutes), as this makes it easier to start and eventually become a self-reinforcing habit.

3. Prioritize Sleep and Exercise

Focus on fundamental aspects of health like sleep hygiene and regular exercise, as these can significantly enhance resilience against mental health challenges and improve overall well-being.

4. Engage in Social Laughter

Laugh with friends to release endogenous opioids, which can reduce pain, increase physical endurance, and lower physiological stress signals during conflict, enhancing social cohesion.

5. Tune into Body’s Internal Signals

Practice tuning into your body’s own internal signals (interoception) to understand your physical and emotional state, as this can have a profound impact on your well-being.

6. Reframe Pain Perception

Seek temporary relief from painful symptoms to change your interpretation of those signals, making them feel less permanent or all-encompassing, which is key to overcoming them.

7. Optimize Work Based on Chronotype

Understand your chronotype (morning person vs. night owl) and modify your work schedule to align with your most energetic and motivated hours for better output and personal well-being.

8. Find Enjoyable Movement

When increasing movement for mental or physical health, prioritize activities you genuinely enjoy, as it’s a much easier and more sustainable path than forcing yourself to do something you dislike.

9. Boost Interoception with Mindfulness

Practice mindfulness-based therapies or simple exercises like training to attend to your heartbeat to boost interoception, which may be a key mechanism for improving anxiety and depression.

10. Distinguish Hunger from Emotions

Practice detecting subtle physiological differences, such as stomach rumbling, to distinguish true hunger from emotional states like irritability, which can be mistakenly interpreted as ‘hangry.’

11. Seek Positive Prediction Errors

Engage in activities that might unexpectedly bring pleasure, creating a ‘positive prediction error’ that can help integrate a more positive outlook into your model of the world.

12. Train Interoceptive Control for Anxiety

Engage in interoceptive training, such as controlled breathing during heightened physiological signals, to learn to control your body’s responses and potentially stop panic attacks.

13. Listen to Hunger and Fullness Cues

Pay attention to your body’s internal signals of hunger and fullness, as a deficit in interpreting these interoceptive cues can lead to dysfunctional eating patterns and negatively impact physical health.

14. Use Brief Discomfort for Mood

Engage in brief discomfort, such as very cold water immersion, to induce endogenous opioid release in the brain, which can acutely boost mood and help push through pain.

15. Clinicians: Optimize Patient Communication

Clinicians should recognize the immense power of the placebo effect and prioritize how they communicate with patients, as their manner and words can significantly influence patient expectations and treatment outcomes.

16. Be Mindful of Wearable Data’s Impact

If using health wearables, be aware that negative data (e.g., poor sleep quality) can have negative repercussions on your subjective well-being, potentially more than your own perception.

17. Apply & Teach New Insights

To enhance learning and retention, identify one new insight to apply to your own life and one to teach to someone else.

18. Be Architect of Your Health

Take ownership of your health, understanding that making lifestyle changes is always worthwhile because feeling better leads to living more.

19. Recognize Body-Brain Interconnection

Understand that the body and brain are not separate entities; physical health is consequential to the brain, and artificial divisions between physical and mental health are misleading.

20. Be Mindful of Social Contagion

Be aware that mental and even physical symptoms can be transmitted or enhanced in social settings, especially during adolescence, due to unconscious social contagion.
