<title>Introduction</title>
<p>A clown is an artistic figure who is always surrounded by the unexpected and who knows how to make the most of every annoyance. They are performers who provoke failures but also overcome them by playing with imagination and poetics. The clown is a character firmly situated in the present who always exhibits a contrast, either through their image or their actions, consequently achieving laughter and humor. Approximately 50 years ago, they began moving from the stage to visit places where healthcare was offered (<xref ref-type="bibr" rid="B30">Spitzer, 2006</xref>), thanks to their ability to listen sensitively to people and communicate creatively in both verbal and nonverbal ways.</p>
<p>Clowns are also symbols of human vulnerability who empathize with patient uncertainty and cope with and fight stress, anxiety, and pain (<xref ref-type="bibr" rid="B12">Fusetti et al., 2022</xref>). Thus, they evolved to become known as clown doctors, hospital clowns, or healthcare or therapeutic clowns. The effect of these professionals has been evaluated and studied in various populations and medical contexts, confirming their impact and supporting this type of intervention, and they are now established figures in the healthcare system (<xref ref-type="bibr" rid="B10">Dionigi et al., 2012</xref>).</p>
<p>Professional clown visitors reduce the anxiety and stress levels of hospitalized children and their families. <xref ref-type="bibr" rid="B11">Dionigi et al. (2014)</xref> observed decreased levels of preoperative anxiety in children, while <xref ref-type="bibr" rid="B23">Melvin et al. (2025)</xref> reported positive effects in psychiatric units for adolescents. Several reviews and meta-analyses have validated the general effect of modulating stress and anxiety (<xref ref-type="bibr" rid="B31">Sridharan and Sivaramakrishnan, 2016</xref>; <xref ref-type="bibr" rid="B16">Kasem et al., 2023</xref>; <xref ref-type="bibr" rid="B22">Lopes-Junior et al., 2020</xref>; <xref ref-type="bibr" rid="B35">Wang et al., 2024</xref>). <xref ref-type="bibr" rid="B37">Xin et al. (2024)</xref> also reported benefits in pain perception and cognitive behavioral issues, specifically in the context of children with autism. A recent study comparing a large sample of hospitalized pediatric patients with control groups found decreased levels of pain and crying time and improved levels of physical stress markers, such as increased oxytocin levels and lower cortisol levels (<xref ref-type="bibr" rid="B27">S&#x000E1;nchez et al., 2024</xref>).</p>
<p>Initially linked to pediatric healthcare, hospital clown organizations have expanded their scope to adult and senior care settings (<xref ref-type="bibr" rid="B8">Dionigi and Canestrari, 2016</xref>), and, with adaptations of their approach and routines, they are currently used in dementia care. Because of advanced age or illnesses associated with the aging process, clowns in senior healthcare increasingly connect with end-of-life contexts and are also beginning to be integrated into adult oncology and palliative care units.</p></sec>
<sec id="s2">
<label>2</label>
<title>Is there room for clowns in oncology and palliative care?</title>
<p>Healthcare clowns are affectionate and attentive artists who act in the present, channeling emotions and stimulating their audience with surprise, but without generating agitation or nervousness (<xref ref-type="bibr" rid="B3">Auerbach, 2017</xref>). Professional hospital clowns can identify when the moment to perform their interventions arises (<xref ref-type="bibr" rid="B25">Pinna et al., 2018</xref>), prioritizing respect and attentive listening in all circumstances while remaining extremely sensitive to patient silence, anger, or frustration.</p>
<p>Their aim is to support each individual, making each person feel valued and special, enriching their interactions with resources ranging from music and magic to juggling and poetry, which allows their audience to process grief and difficulties related to illness, including severe conditions in oncology and palliative care.</p>
<p>As mentioned, research experiences have supported the appropriateness of the presence of specialized clowns in these sensitive spaces. In pediatric oncology, findings include lower levels of the stress biomarker salivary cortisol, lower fatigue scale scores (<xref ref-type="bibr" rid="B22">Lopes-Junior et al., 2020</xref>), and less pain and distress, along with enhanced calm during chemotherapy sessions (<xref ref-type="bibr" rid="B2">Arriaga et al., 2020</xref>; <xref ref-type="bibr" rid="B18">Kurudirek and Arikan, 2020</xref>). <xref ref-type="bibr" rid="B28">Santarpia et al. (2023)</xref> addressed the spiritual domains that clowns can manage during their visits to pediatric palliative care units. Also in pediatric palliative care, healthcare clowns play a significant role in modulating perceptions of hair loss or in enabling children to choose the clown to express emotions that the child does not usually show their parents, such as sadness (<xref ref-type="bibr" rid="B32">Valdebenito, 2021</xref>, <xref ref-type="bibr" rid="B33">2022</xref>; <xref ref-type="bibr" rid="B34">Valdebenito and S&#x000E1;nchez, 2021</xref>).</p>
<p>Studies have shown that hospital clowns also work well with the adult population. <xref ref-type="bibr" rid="B8">Dionigi and Canestrari (2016)</xref> confirmed that clown interventions enhance well-being by reducing the intensity of emotions such as stress and anxiety. <xref ref-type="bibr" rid="B6">Casellas-Grau et al. (2020)</xref> studied a sample of adult oncology patients and their relatives, finding improved levels of fatigue, discouragement, anxiety, boredom, sadness, anger, laughter, happiness, worry, disappointment, and fear.</p></sec>

<title>Functions of healthcare clowns in oncology and palliative care settings</title>
<p>Understanding the specific way in which clowns achieve these outcomes requires consideration of the precise functions that benefit the psychosocial well-being of patients, their families, and staff. The following five functions are not limited to oncology and palliative care; however, it is in these services that they can play a particularly outstanding role.</p>
<sec>
<label>3.1</label>
<title>Surprise</title>
<p>Clowns operate primarily by reacting from the logic of emotions, and the first emotion present in an encounter with a clown is surprise (<xref ref-type="bibr" rid="B21">Linge, 2011</xref>). The salience of a clown&#x00027;s presence serves as a powerful stimulus capable of distracting from fear, anxiety, stress, uncertainty, and even certain degrees of pain (<xref ref-type="bibr" rid="B12">Fusetti et al., 2022</xref>; <xref ref-type="bibr" rid="B7">Ding et al., 2022</xref>). Surprise and the subsequent emotions it generates, such as joy and tenderness, are incompatible with simultaneously experiencing negative emotional states.</p>
<p>Clowns in hospitals are highly unexpected interlocutors. Novelty, naturally linked to surprise, is a powerful property of stimuli that directly captures attention (<xref ref-type="bibr" rid="B14">Horstmann and Herwig, 2016</xref>). Surprising events generate intense memories, associated in this case with the moment a clown appears.</p>
<p><xref ref-type="bibr" rid="B21">Linge (2011)</xref> described the surprise associated with the presence of a clown as a starting point for establishing a connection or a moment of insight. This initial surprise can act as a direct way to unlock other emotions and prepare patients for play and imagination (<xref ref-type="bibr" rid="B20">Linge, 2008</xref>).</p>
</sec>
<sec>
<label>3.2</label>
<title>Imagination and play</title>
<p>A fundamental aspect of a clown&#x00027;s basic training is broadening the capacity to enhance unexpected ways of responding to stimuli or solving problems. This imaginative attitude is in constant use and lived naturally. <xref ref-type="bibr" rid="B29">Santos et al. (2021)</xref> claimed that interaction with clowns encourages patients to establish new, clever, and creative reevaluations about life needs and adaptations (<xref ref-type="bibr" rid="B1">Anes and Obi, 2014</xref>).</p>
<p>This can be expressed by the term &#x0201C;playfulness&#x0201D;, which refers to the disposition to find new meanings in everyday or normative objects or situations, accompanied by feelings of joy, fun, and spontaneity (<xref ref-type="bibr" rid="B5">Bozionelos and Bozionelos, 1999</xref>; <xref ref-type="bibr" rid="B9">Dionigi et al., 2025</xref>). Playfulness is a measurable concept (<xref ref-type="bibr" rid="B4">Barnett, 1990</xref>; <xref ref-type="bibr" rid="B19">Lau et al., 2025</xref>) and is understood as a basic and essential seed of creativity that is inherent in the capacity to adapt and learn at any age.</p>
<p>For a clown, play is not infantilization but rather an imaginative strategy full of humanity, warmth, enthusiasm, closeness, and, of course, empathy. A clown&#x00027;s main mission in a hospital is to construct a space for imagination, transforming that space through play. Together with the patient, clowns physically embody and develop the patient&#x00027;s creative, living stories (<xref ref-type="bibr" rid="B17">Kontos et al., 2017</xref>), memories, and desires, moving them away from the hospital room to the seaside, mountains, forests, or anywhere else the patient wishes to go.</p>
</sec>
<sec>
<label>3.3</label>
<title>Humor to dissolve tension</title>
<p><xref ref-type="bibr" rid="B25">Pinna et al. (2018)</xref> conducted a systematic review of the use of humor in palliative care, observing a list of useful functions of humor: transforming space, relieving moments of despair, distancing oneself from the medical context and situations of pain, handling and expressing personal vulnerability, releasing anxiety, stress, and fear, enhancing self-esteem, arousing imagination, and promoting positive remembrance. This description of humor aligns with the interventions of medical clowns.</p>
<p>Clowns can find laughter on many occasions, breaking the tension and stress present in these spaces by using the unexpected contrast of humor, but never forcing it. What happens is always done with sensitivity and their ability to build a shared expression.</p>
</sec>
<sec>
<label>3.4</label>
<title>Communication and expression</title>
<p>Healthcare clowns employ several skills to enhance communication, which is especially beneficial when interacting with patients who have verbal impairments. This is illustrated first of all by their proficiency in using non-verbal expressiveness and gestures. Second, communication happens using music, either by bringing songs that are meaningful to patients in the hospital or by leveraging their high sensitivity to listen to and respond to the rhythms of the space, adjusting to the tempo of the interaction established between interlocutors. A third benefit lies in establishing communication through the gaze and basic emotional expression, which also stimulates the expression of others&#x00027; emotions.</p>
<p>This becomes especially relevant when considering older adults receiving oncology and palliative care who may also be experiencing dementia or speech problems derived from neurological damage. This was demonstrated using an ethogram of micro-gestures, which found a significant increase in communicative intent among the older population in interactions with healthcare clowns (<xref ref-type="bibr" rid="B24">P&#x000E9;rez-Gonz&#x000E1;lez and Carnero-Sierra, 2023</xref>). Clowns have excellent skills for capturing and interpreting subtle signals from people and their environments, allowing them to adapt their proposals and share in the experience of others. They also have outstanding potential to understand and respond to the emotional states of others, acting by focusing on the present and integrating elements provided by their artistic tools to enhance participant engagement (Roberts et al., <xref ref-type="bibr" rid="B26">2024</xref>).</p>
</sec>
<sec>
<label>3.5</label>
<title>Support</title>
<p>The hospital clown is clearly a supportive figure (<xref ref-type="bibr" rid="B29">Santos et al., 2021</xref>), providing emotional release and psychological relief (<xref ref-type="bibr" rid="B34">Valdebenito and S&#x000E1;nchez, 2021</xref>), as shown by the various measures of anxiety and stress previously mentioned. A clown&#x00027;s intervention serves as an acknowledgment of the individual, distinguishing them from their illness and giving priority to the patient&#x00027;s initiative and right to make their own decisions (<xref ref-type="bibr" rid="B36">Warren and Spitzer, 2011</xref>). In the specific context of the end-of-life process, clowns work as a channel to celebrate both life and memories.</p>
<p>In addition, clown support also extends to staff. Brief encounters with members of staff provide relief through distraction and playfulness (<xref ref-type="bibr" rid="B13">Gomberg et al., 2020</xref>), particularly for mental health professionals, who are at the end of the care chain.</p>
<p>Additionally, clowns are a source of artistic tools that enrich and support healthcare teams, offering great opportunities for physical and cognitive stimulation, and encouraging initiative when performing sensorial, speech, or movement rehabilitation exercises. Furthermore, clowns encourage eating, taking medication, or accepting invasive practices such as injections (<xref ref-type="bibr" rid="B15">Javed et al., 2021</xref>). Storytelling, the transformative and elaborate function of play, physical theater, and the grammar of movement, music mixed with presence, juggling, magic tricks, objects, and theater, are tools at the service of clowns in their interventions. They can collaborate with psychosocial professionals in oncological and palliative settings.</p></sec>

<title>Discussion</title>
<p>Healthcare clowns surprise and stir emotions in settings of grief and pain through humor, but are also attuned to opportunities to channel and process negative emotions through play and imagination. They are effective figures of support and reminders of the right to imagine and play, regardless of condition or age. This makes the clown duo a highly versatile tool for addressing needs that arise in the contexts of oncology or palliative care, whether with pediatric or adult patients, celebrating all possibilities and reinforcing every achievement and attempt at communication.</p>
<p>Another important point is the capacity of clown interventions to generate a strong psychological impact in a relatively short amount of time. A single performance can create intense memories due to its significance and unexpected presence. Another essential aspect of clowns is their ability to work in the absence of verbal language, always respecting reality and individuality while using their creativity to encourage patients&#x00027; expression.</p>
<p>The clown is an interlocutor who naturally experiences all facets of being human. Ultimately, this is the essence of the clown: their poetic presence and actions transform the place and channel the emotional circumstances of extreme moments (<xref ref-type="bibr" rid="B28">Santarpia et al., 2023</xref>). Poetics also brings psychological comfort. Being a clown for patients experiencing grave circumstances is more than just dressing up and wearing a red rubber nose: a clown is a human being who sublimates pain through art and humanity.</p></sec>
