Why Does Stress Rewire Your Brain for Negativity?

Stress has a major impact on your brain. Ever wondered why your mind goes blank during important moments? Why you forget everything during tests, presentations, or high-pressure situations?

This video reveals the neuroscience behind what's actually happening in your brain when stress hits—and why chronic stress literally rewires your brain for negativity.

What you'll learn:
🧠 The inverted U-curve: Why moderate stress helps but high stress destroys performance
📚 Why test anxiety makes you forget everything you studied (hippocampus shutdown)
🎭 The neuroscience behind stage fright and "going blank"
⚠️ How your amygdala gets STRONGER with stress (while memory gets weaker)
🔄 The vicious cycle: How chronic stress rewires your brain for anxiety and depression

The most important takeaway: Your brain's stress response was designed for short-term survival, not modern chronic stress. Understanding this biology is the first step to breaking free from the negativity spiral.

This explains why some people seem stuck in negative thinking patterns—it's not a character flaw, it's neuroplasticity gone wrong.
