World Laughter Day: Can laughter really make you healthier?

It is often said that laughter is the best medicine. Since ancient times, civilizations such as the Greeks and Romans recognized its therapeutic value: they believed it could relieve physical discomfort, reduce stress, and contribute to emotional balance.

Every year, on the first Sunday of May (May 3 in 2026), World Laughter Day is celebrated—a date intended to promote joy, mental well-being, and connection among people through something as simple as laughing. This celebration also aims to encourage peace, friendship, and greater global awareness.

But are the effects of laughter real?

Laughter is the best medicine

So-called “laughter therapy” is a technique that uses humor as a tool to reduce pain, stress, and negative emotions. Its purpose is to improve quality of life, and it is often used as support in difficult situations or during illness.

When we laugh, the body releases endorphins, neurotransmitters associated with feelings of well-being. These substances not only boost mood but also help reduce stress and strengthen the immune system.

According to researchers at Mayo Clinic, it has been proven that a good laugh has very positive short-term effects. When we laugh, not only is the mind relieved, but physical changes also occur, bringing significant health benefits.

The power of laughter offers the following short-term benefits:

• It increases oxygen intake, helping stimulate organs such as the heart, lungs, and muscles.
• It boosts the release of endorphins in the brain, which can reduce the perception of pain.
• It activates and relieves the stress response.
• It eases tension by relaxing muscles.

According to research highlighted by Psychology Today, people with a good sense of humor who laugh frequently may live longer and achieve better outcomes when dealing with chronic illnesses. Beyond being a temporary mood boost, laughter can be seen as a lifestyle habit that supports long-term physical, mental, and social well-being.

Its long-term benefits include:

• Strengthening the immune system through the release of neuropeptides that help combat stress and potentially more serious illnesses.
• Improving self-esteem and encouraging a more optimistic outlook on life.
• Helping improve sleep, especially in people who suffer from insomnia.
• Making it easier to cope with difficult situations.
• Helping connect with others.
• Improving overall mood.

Here it is: the next time you feel overwhelmed by stress, need to lift your mood, or want to improve your rest, try laughing—whether alone or with others. One way or another, laughter always brings something positive.
