It is said "rice makes good blood" and, in fact, laughter has a validated therapeutic potential, triggers endorphins, natural analgesics able to induce a state of well-being, catecholamines, hormones that produce an improvement in mood, globules whites that protect us from infections and tumors, and immunoglobulins that improve the immune system; all of this reactivates the body's energy and helps us withstand pain. So laughing is a serious thing!

In medicine, in the last 25 years, we talk about psychoneuroimmunology, more commonly known as the connection between body and mind. It is understood that tensions (physical, mental and spiritual) have an effect on the biochemistry and physiology of the body. Extensive studies have shown that in the long run elements such as love, humor, enthusiasm, curiosity, passion, hope, joy, stimulate the immune system and help our bodies fight infection and disease, as well as influencing the way we take care of ourselves. Thanks to the efforts of Patch Adams, doctor and clown who travels the world to explain that you can heal sooner and better by laughing, today the clown doctors are part of hospital departments, such as pediatrics, cardiology, oncology, intensive care and many others with amazing results for healing, thanks to the technique that we could also call good humor. For clown doctors it is not important to make people smile at all costs, but to be there with a heart ready to welcome.

Laughing is already communicating and we learn it as a child, we just have to remember to do it more often as adults; it is a universal and instinctive language, which allows us to express hidden emotions and nuances; it is important that it is a heartfelt laugh, or a sincere smile, that manifests emotions coming from the depth of the individual, a bit like an animal call, innate, with the intrinsic ability to generate others.
