How To Stop Overthinking Things You Can’t Control With Dr Hannah Critchlow

Have you ever wondered why your brain feels like it's working against you when actually, it might just be waiting for you to understand it?
This week I'm joined by Dr. Hannah Critchlow, neuroscientist, Cambridge University researcher, and author of 21st Century Brain, and this conversation genuinely shifted something for me.
Hannah has a way of taking the science of your brain and making it feel like something you can actually use, today. Not in a "10 steps to fix yourself" way.
What we explore together:
• Why does your brain fear uncertainty more than pain itself, and what does that mean for how you handle stress and change?

• Did you know emotional intelligence is a bigger predictor of life satisfaction than IQ, and that it can actually be trained?

• How is your gut shaping your mood, your empathy, and even how kind you are to complete strangers?

• What are sleep, nutrition, and movement really doing for your brain, and why do amino acids matter so much at night?

• Why is walking in nature one of the most underrated tools for emotional regulation?

• What does the rise of AI relationships mean for real human connection, and what are we at risk of losing?

• Why is curiosity our greatest superpower, and how do we protect it?

Love, Sarah Ann 💛
