Your Brain Can't Hustle and Heal at the Same Time ft Dr. Krissy Doyle-Thomas | Episode 154

What does your brain do when you finally rest — and why can't it rest while you're hustling? This week we sit down with Dr. Krissy Doyle-Thomas, medical neuroscientist and professor, for a conversation where faith meets neuroscience. She breaks down why sleep is your brain's housekeeping shift, what gratitude physically does to your prefrontal cortex (and why it's not toxic positivity), and how Romans 12:2 described neuroplasticity centuries before science caught up. Plus: why your brain defaults to the negative, and what that means for young people making big decisions.
