✨ Introduction
As a BA Psychology student passionate about becoming a clinical psychologist, I always wondered what exactly happens inside the brain when we feel anxious. Recently, I discovered something fascinating—microglia, the brain’s immune cells, play a major role in anxiety.
🧠 What Are Microglia?
- Microglia are the brain’s cleanup and defense cells.
- They protect neurons, remove waste, and regulate inflammation.
- When microglia become overactive, they can affect mood and stress.
⸻ 😰 How Microglia Influence Anxiety ⸻
- Overactive microglia release inflammatory chemicals.
- This inflammation disrupts areas responsible for fear and worry (like the amygdala).
- Science suggests that chronic stress can “switch on” microglia, increasing anxiety levels.
👩🎓 Why This Excites Me as a Student
Learning about microglia helped me connect biology with psychology. It reminds me that mental health isn’t “all in the mind”—there are real biological processes behind emotions.
✔ Tips to Boost Your Brain Health
- Good sleep
- Anti-inflammatory foods
- Regular exercise
- Mindfulness practices
Eat “Microglia-Calming” Foods
These reduce inflammation and support mental clarity:
- Walnuts
- Turmeric (with black pepper)
- Green tea
