What Causes Pre-Exam Anxiety?

Cortisol surges: The stress hormone spikes before exams.

Effects on Cognition 🧠

Brain fog 🌫️

Reduced memory recall 🧩

Difficulty concentrating 🎯

Faster fatigue ⚡

Negative thought spirals

The solution: calm anxiety without sedation, sharpen focus without overstimulation.
