EUSTRÉS Y RESPUESTAS NEUROFISIOLÓGICAS EN PARQUES DE ATRACCIONES

Throughout history, amusement parks have been considered purely hedonic spaces associated with immediate and empty pleasure, ignoring a eudaimonic component: the potential to produce positive effects on the organism. In this sense, the objective of this article is to synthesize existing evidence through an umbrella review following PRISMA 2020 guidelines, on the positive neurophysiological responses induced by eustress experiences and their relationship with EWB, cognition, and resilience in humans. Now, in order to achieve this, a screening of 98 sources was performed, from which 31 final studies were selected. Among these, six systematic reviews and meta-analyses published between August 2020 and February 2025 formed the main analysis. The results demonstrate that intense attractions, such as roller coasters, are associated with states of happiness linked to the release of dopamine and endorphins after the successful resolution of a perceived stressor. Evidence suggests that this process (eustress) might improve concentration, strengthen the immune system by mobilizing cells (lymphocytes and NK), and promote group cohesion through the release of oxytocin. As well, G-forces may contribute to balance training and the reduction of psychomotor restlessness. And finally, it is concluded that these recreational experiences can activate neurobiological systems related to reward and adaptation, inviting the scientific community to rethink their role in promoting mental health and strengthening psychological resilience.
