On a recent episode of her podcast, bestselling author Mel Robbins tackles the topic of happiness — specifically fun.

“Lately, I’ve been feeling like life just isn’t fun anymore,” she said on the show.

Robbins went on to list a number of reasons for this. For example, people are burned out, overwhelmed by life and world events, and more focused on what’s taking place on their phone than in their physical life, she says.

But “fun isn’t just some frivolous thing,” she said. “Micro-moments of fun, I’m talking laughter, silliness, joy, they’re critical for happiness, resilience.”

The benefits of laughter also include stress relief, pain relief and a stronger immune system, according to the Mayo Clinic.
