😀 The Science of Smiling: How Facial Expressions Affect Mood
Introduction
Have you ever smiled when you didn’t feel like it, only to feel a bit better afterward? That’s not just coincidence—it’s backed by science. Your facial expressions can influence your emotions more than you might think.
🧠 What Happens in the Brain When You Smile
Smiling triggers the release of feel-good neurotransmitters, such as:
-
Dopamine – Elevates mood and motivation.
-
Endorphins – Natural painkillers that reduce stress.
-
Serotonin – Promotes emotional balance.
Even a fake smile can stimulate these chemicals, thanks to the facial feedback hypothesis—a theory stating that facial movements can influence emotional experience.
