Smile vs Laughter: What’s Scientifically Better?
When you think of happiness, what comes to your mind first, smiling or laughing? Both are natural ways to show joy, and they make us feel good. But which one is better for your health and happiness? In this blog post, we’ll look at the science behind smiling and laughter, and find out which one is more helpful for your body, mind, and relationships.
What Is a Smile?
A smile is a facial expression where the corners of your mouth turn upward. Sometimes, a real smile also includes the eyes. People smile when they feel happy, but also when they are shy, nervous, or trying to be polite.

Types of Smiles:
- Duchenne smile: A true, happy smile with the eyes and mouth.
- Social smile: A polite smile, often used in formal or public situations.
- Nervous smile: A smile used when someone feels uncomfortable or unsure.
What Happens When You Smile?
Smiling helps your brain release chemicals like dopamine, endorphins, and serotonin. These chemicals help you feel happy and calm. Some studies say even if you force a smile, your brain may still feel the positive effects.
Benefits of Smiling:
- Lowers stress
- Makes your mood better
- Strengthens your immune system
- Helps you connect with others
- Makes you look friendly and honest
What Is Laughter?
Laughter is a stronger action than smiling. It uses your mouth, voice, lungs, and body. We usually laugh when something is funny, but also when we’re surprised, excited, or feeling awkward.
Types of Laughter:
- Spontaneous laughter: Real and natural, often when we hear a joke.
- Simulated laughter: Practiced laughter, used in laughter yoga or therapy.
- Nervous laughter: Happens when we are uncomfortable or anxious.

What Happens When You Laugh?
Laughing also releases happy chemicals like dopamine and endorphins. It makes your body take in more oxygen and helps your heart and lungs work better. Laughter also helps reduce pain and boosts your mood.
Benefits of Laughter:
- Reduces stress
- Supports heart and lung health
- Increases pain tolerance
- Improves mood
- Helps build strong friendships and relationships
