What Constant Stress Does To Your Brain

Your brain wasn’t built for nonstop pressure—and when stress becomes your norm, it quietly starts rewiring everything.

This video breaks down how cortisol hijacks your brain’s wiring, what it looks like over time, and why burnout feels like you’re not even “you” anymore. Have you noticed yourself changing lately—maybe more than you’d like?
