You’ve probably heard that smiling can make you happier. It’s a lovely idea, and many people notice that a smile can lift their mood a little. Research on smiling and mood is mixed, though: some studies suggest a small effect, while others don’t find much at all.

Here’s what a smile can, and can’t, do.

What a smile can do

A smile can be a gentle way to connect. Smiling at someone can make an interaction feel warmer, and a smile is often returned. Some people find that a soft smile helps them relax or reminds them to be kind to themselves.

What a smile can’t do

A smile isn’t a quick fix for sadness or stress. Forcing a smile when you feel low can sometimes make you feel more disconnected from your real feelings. You don’t need to smile to be good company or to be okay.

Let feelings be real

It’s fine to have a serious face on a hard day. Feelings come and go, and they don’t need to be covered up. If you feel like smiling, wonderful. If not, that’s okay too.

Finding natural smiles

Instead of forcing a smile, notice what brings one naturally: a friend’s message, a pet, a funny memory, sunlight on your face. These small moments can be worth seeking out.

How little is enough

Today, notice one thing that makes you smile naturally, and let yourself enjoy it.
