🧠 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.
