Based on biophilia theory, which proposes benefits of connection with nature for physical and mental health, the study aimed to analyze the effects of observational exposure to green environments on test anxiety, academic performance, and neurophysiological variables. Specific focus was on heart rate variability (HRV). An experimental, quantitative, controlled, randomized block, double-blind methodology was used with 8 Physiotherapy students from UFPB distributed into two groups: visual exposure to nature and control without exposure. Instruments included the State-Trait Anxiety Inventory (STAI), Environmental Connection Scale (ECS), Polar H10 heart rate monitor for HRV analysis via Kubios software, plus academic performance evaluation. Data collection occurred at three moments: two weeks before, during, and two weeks after the practical evaluation. Results demonstrated that nature exposure favored better autonomic recovery in the post-test period, with lower heart rate (80.0 ± 8.1 bpm vs 86.5 ± 7.7 in control) and superior elevations in parasympathetic indices (pNN50 and RMSSD), indicating greater physiological relaxation. Although there was no statistically significant difference in academic performance between groups, a tendency for higher grades was observed in the intervention group. It is concluded that observation of green environments during evaluations constitutes a promising strategy for academic stress modulation and psychophysiological balance promotion, suggesting the inclusion of natural spaces in universities as a complementary tool for student well-being.; RESUMEN. Esta disertación investiga los efectos de la exposición a ambientes verdes en la regulación de la ansiedad ante los exámenes en estudiantes universitarios durante evaluaciones prácticas de Anatomía Humana. Fundamentado en la teoría de la biofilia, que propone beneficios de la conexión con la naturaleza para la salud física y mental, el estudio tuvo como objetivo general analizar los efectos de la exposición observacional a ambientes verdes sobre la ansiedad ante exámenes, rendimiento académico y variables neurofisiológicas, específicamente la variabilidad de la frecuencia cardíaca (VFC). Se utilizó metodología experimental, cuantitativa, controlada, randomizada en bloques y doble ciego, con 8 estudiantes de Fisioterapia de la UFPB distribuidos en dos grupos: exposición visual a la naturaleza y control sin exposición. Los instrumentos incluyeron el Inventario de Ansiedad Rasgo-Estado (IDARE), Escala de Conexión con la Naturaleza (ECN), monitor de frecuencia cardíaca Polar H10 para análisis de VFC vía software Kubios, además de la evaluación del rendimiento académico. Las recolecciones ocurrieron en tres momentos: dos semanas antes, durante y dos semanas después de la evaluación práctica. Los resultados demostraron que la exposición a la naturaleza favoreció mejor recuperación autonómica en el período post-test, con menor frecuencia cardíaca (80,0 ± 8,1 lpm vs 86,5 ± 7,7 en control) y elevaciones superiores en los índices parasimpáticos (pNN50 y RMSSD), indicando mayor relajación fisiológica. Aunque no hubo diferencia estadística significativa en el rendimiento académico entre grupos, se observó tendencia de notas superiores en el grupo intervención. Se concluye que la observación de ambientes verdes durante evaluaciones constituye estrategia promisoria en la modulación del estrés académico y promoción del equilibrio psicofisiológico, sugiriendo la inclusión de espacios naturales en universidades como herramienta complementaria para el bienestar estudiantil.

One of the hospital sectors where this assistance is carried out is the Intensive Care Unit (ICU). Professionals working in shifts are exposed to specific occupational variables that often lead to sleep deprivation, fatigue, and stress, among other factors that may affect their executive functioning and sleep. Objective: To evaluate the predictive factors of executive functioning and sleep among healthcare professionals working in an Intensive Care Unit. Method: This was a cross- sectional, analytical, and exploratory study, using specific questionnaires administered at the end of day and night shifts to assess executive functioning (ADEXI), sleep quality (PSQI- BR), and daytime sleepiness (ESE and ESS) in a sample of 71 healthcare professionals (physicians, physiotherapists, nurses, and nursing technicians) from the Adult ICU of the Lauro Wanderley University Hospital (HULW), in João Pessoa – Paraíba. Results: The sample was mostly composed of married individuals (57.7%), females (62%), with a mean age of 45.3 years, holding a postgraduate degree (64.8%), and nursing technicians were the majority (46.5%). Regarding executive functioning, inferential analysis revealed a statistically significant relationship between age and working memory (the older the age, the better the performance), and between sex and inhibitory control (females showed worse performance). The variable ―hours of sleep/rest per shift‖ was significant (sleeping less than 6 hours per shift increased the prevalence of poor sleep quality), and for each additional weekly working hour, there was a 10% increase in the prevalence of poor sleep quality among these professionals. The prevalence of EDS was 53.5% according to the ESE and 36.6% according to the ESS. The variable ―mixed work shift‖ was also significant, increasing the prevalence of excessive sleepiness by 194% in these professionals. Conclusion: This study was consistent with the existing literature in showing a critical relationship between sleep and executive functioning, and that healthcare professionals are susceptible to changes in these outcomes due to their distinct work routine.; RESUMEN Introducción: El régimen de trabajo por turnos es una forma común de organización laboral en el ámbito hospitalario, lo que permite una atención integral y continua a los pacientes. Uno de los sectores hospitalarios en los que se desarrolla esta asistencia es la Unidad de Cuidados Intensivos (UCI). Los profesionales que trabajan en turnos están expuestos a variables laborales diferenciadas que suelen conducir a privación del sueño, fatiga y estrés, entre otros factores que pueden afectar su funcionamiento ejecutivo y su sueño. Objetivo: Evaluar los factores predictores del funcionamiento ejecutivo y del sueño de los profesionales de la salud que trabajan en una Unidad de Cuidados Intensivos. Método: Se trata de un estudio transversal, analítico y exploratorio, con aplicación de cuestionarios específicos al final de los turnos diurno y nocturno para evaluar el funcionamiento ejecutivo (ADEXI), la calidad del sueño (PSQI-BR) y la somnolencia diurna (ESE y ESS) en una muestra de 71 profesionales de la salud (médicos, fisioterapeutas, enfermeros y técnicos de enfermería) de la UCI de adultos del Hospital Universitario Lauro Wanderley (HULW), en el municipio de João Pessoa – Paraíba. Resultados: La muestra estuvo compuesta en su mayoría por personas casadas (57,7%), del sexo femenino (62%), con una media de edad de 45,3 años, con posgrado (64,8%), y los técnicos de enfermería fueron mayoría (46,5%). En el funcionamiento ejecutivo, el análisis inferencial reveló una relación estadísticamente significativa entre la edad y la memoria de trabajo (a mayor edad, mejor desempeño) y entre el sexo y el control inhibitorio (el sexo femenino presentó peor desempeño). La variable ―horas de sueño/descanso por turno‖ fue significativa (dormir menos de 6 horas por turno aumenta la prevalencia de mala calidad del sueño), y por cada hora adicional en la carga horaria semanal se observó un aumento del 10% en la prevalencia de mala calidad del sueño entre estos profesionales. La prevalencia de SDE fue del 53,5% según la ESE y del 36,6% según la ESS. La variable ―turno de trabajo mixto‖ también fue significativa, aumentando en un 194% la prevalencia de somnolencia excesiva en estos profesionales. Conclusión: Este estudio fue consistente con la literatura existente al mostrar que existe una relación crítica entre el sueño y el funcionamiento ejecutivo, y que los profesionales de la salud están susceptibles a alteraciones en estos desenlaces debido a su rutina laboral diferenciada.

This study combined findings from three complementary studies. The first involved 33 children aged 5 to 7 years, divided into three groups (microcephaly due to ZIKV, microcephaly due to other causes, and typical children). They were assessed for temperament, functionality, and gross motor strength using the Children's Behavior Questionnaire (CBQ), the International Classification of Functioning (ICF), and the Gross Motor Function Classification System (GMFCS). The results indicated a significant impact of microcephaly, regardless of etiology, on physical, emotional, and behavioral aspects. In the second study, 11 children with microcephaly were monitored between 2019 and 2023, revealing significant differences in the Negative Affect and Effortful Control domains of the CBQ-SF, with worsening during the COVID-19 pandemic, associated with reduced social interactions and the interruption of essential therapies. In the third study, reports from informal caregivers revealed high burden and poor quality of life, highlighting the psychosocial impact of continuous care. The findings reinforce the need for public policies that ensure the continuity of multidisciplinary interventions and support for caregivers, even in social isolation settings, aiming to mitigate harm to child development and family well-being.

A growing body of evidence suggests that contact with nature promotes significant restorative effects, both psychological and physiological. However, in urban settings, access to natural environments can be limited, prompting the exploration of alternatives such as virtual reality (VR). This experimental study, using a crossover design, aimed to investigate the immediate effects of a brief exposure to virtual nature—via the game Nature Treks VR—on heart rate variability (HRV) in university students following a cognitive stressor. A total of 39 participants were randomly assigned to experimental and control groups. Continuous physiological data were collected using the Polar H10 chest strap, and psychological scales were administered at baseline. Results indicated that both VR and passive rest facilitated autonomic recovery. Although no significant differences were observed between conditions for most HRV indices, a significant reduction in heart rate was found in the group exposed to VR. Furthermore, symptoms of depression, stress, mindfulness levels, and life satisfaction showed meaningful associations with physiological indices, suggesting that individual characteristics influence autonomic recovery responses. These findings support the potential of virtual nature as a complementary tool for well-being promotion, particularly in academic environments, and underscore the need for future studies with larger samples and longitudinal designs.
