This study investigates the effectiveness of watering indoor plants as a stress-reduction strategy compared to engaging in computer tasks among college students. Participants randomly assigned to one of two groups each performed their respective activities for 15 min. A comprehensive evaluation included measures of blood pressure, electroencephalography, the semantic differential method and the state-trait anxiety inventory to assess emotional and physiological responses. Results revealed a significant decrease in systolic blood pressure, while electroencephalography data showed neural patterns associated with a more relaxed cognitive state. Participants in the plant-watering group also exhibited higher meditation scores, reinforcing the stress-relieving potential of this intervention. Psychological data indicated that those in the plant-watering group reported greater relaxation, comfort and perceived connection to nature, as well as lower anxiety scores, compared to the computer task group. These findings highlight the benefits of nature-based activities in reducing stress and promoting well-being in academic and work environments.

The increasing use of technological devices has contributed to rising psychological stress among young people. Effectively managing this stress is essential for improving mental health and reducing its impact. This study examines the psychophysiological benefits of participating in a 15-min nature-based filming activity among modern Chinese adults. Participants were instructed to create a nature-themed film using a camera, and their experiences were compared to a control activity involving city-themed filmmaking for the same duration. Various measures, including blood pressure, the State-Trait Anxiety Inventory (STAI-S), electroencephalography (EEG), and the semantic differential method (SDM), were used to assess the effects of both activities.The results showed significant reductions in both diastolic and systolic blood pressure, along with notable changes in brain activity, during the nature-based filming. Psychological responses indicated that participants felt “moderately relaxed,” “moderately comfortable,” and “moderately natural,” with lower anxiety levels after the nature-based filming compared to the control group. These findings suggest that engaging in outdoor, nature-based filming can effectively reduce psychophysiological stress in Chinese adults.

Chinese classical gardens serve as restorative environments that epitomize the essence of Chinese aesthetics. Despite their recognized Outstanding Universal Value, research on the multisensory experiences and associated well-being benefits they offer remains insufficiently explored. This study examines the Humble Administrator’s Garden through a multisensory framework incorporating visual, auditory, and tactile dimensions. By employing a mixed methods approach that integrates questionnaires and physiological measurements, we assessed the psychophysiological responses of 78 participants before and after entering the garden, as well as at distinct landscape points. Key findings reveal the following: (1) the traditional garden environment evoked significant positive perceptual effects; (2) the garden, with its diverse combination of landscape elements—including architecture, water features, rock formations, and plants—was strongly associated with enhanced well-being outcomes. A higher diversity of visual landscapes yielded more pronounced benefits, with water features exerting the most substantial positive influence on health, while rock formations showed a comparatively lesser effect; and (3) physiological and psychological responses of participants varied within the same landscape setting, with tactile experiences eliciting the most profound psychological changes. These findings underscore the pivotal role of multisensory engagement in Chinese classical gardens for fostering well-being, offering valuable health-related benefits beyond their cultural and ecological significance.

The dual challenges of global aging and intensifying urban heat demand innovative, evidence-based strategies to foster thermally and psychologically comfortable environments for vulnerable populations, particularly the elderly. Despite the documented benefits of urban greenery, the species-specific impacts of urban trees on thermal comfort and well-being remain underexplored. This study investigates how distinct tree species—Camphora officinarum (camphor), Platanus acerifolia (London plane), and Ginkgo biloba (ginkgo)—regulate urban microclimates and support elderly well-being during hot summer days. Conducted at five sites in Shanghai, including a control site and four vegetated plots, this study engaged 210 elderly participants. Microclimatic variables were measured using the physiological equivalent temperature (PET) alongside air temperature, humidity, and wind speed. Physiological responses, assessed through heart rate variability (HRV), and psychological outcomes, evaluated via validated self-report scales, were analyzed. The results revealed that dense-canopy trees significantly reduced PET, enhanced thermal comfort, and improved ROS and SVS scores, while lower LF/HF ratios indicated reduced physiological stress. Correlation analyses underscored the pivotal role of canopy density (SVF) in fostering psychological and physiological well-being. Camphor and London plane trees consistently provided the greatest benefits, emphasizing the importance of species selection in urban greening strategies. These findings underscore the critical role of species selection in urban forestry to mitigate heat stress and foster age-friendly resilience. Practical implications emphasize integrating dense-canopy species into urban landscapes to enhance microclimate regulation and public health.

Background: Gardening as a leisure activity has been shown to be potentially beneficial for older adults, this study aimed to assess the physiological and psychological impacts of a specific horticultural activity, watering indoor plants, compared with playing a computer game - the Klondike Solitaire Card Game. Methods: This crossover study included 100 older adults recruited from a nursing care facility for older people in Shanghai, China. They were allocated to either engage in watering indoor plants (horticultural group) or playing a computer game (control group). For the inclusion criteria, screening for cognitive function was conducted to exclude those with severe cognitive impairments, thereby focusing on those capable of participating fully in the study activities. Brainwave activities, blood pressure, and psychological states were measured through pre- and post-test questionnaires to evaluate the physiological and psychological effects. Results: The activity of watering indoor plants was associated with significant reductions in both systolic and diastolic blood pressure, in contrast to the computer game activity. Additionally, participants in the horticultural group showed increased brainwave mean values, indicating heightened relaxation and focus, while decreases were observed in the control group. The experimental group reported reduced anxiety scores, along with increased feelings of comfort and relaxation, and also exhibited significantly higher meditation levels, which indicates a profound mental relaxation effect. Conclusion: Our findings suggest that engaging in indoor horticultural activities, such as watering houseplants for 10 minutes, can reduce mental and physical stress levels in older adults.

In today's fast‐paced society, escalating work and academic pressures have led to rising stress levels. While numerous studies have explored adolescent mental health, there has been a lack of focus on “educational stress” among Chinese students. This study sought to understand the psychological and physiological effects of educational stress in Chinese university students. We studied the impact of a 5‐min nature photography session on campus compared with a control activity of photographing urban settings near campus. Data were collected using blood pressure measurements, electroencephalography (EEG), the Semantic Differential Method (SDM), and the State–Trait Anxiety Inventory (STAI) in order to understand psychophysiological reactions. The findings from the SDM and STAI assessments indicated that students felt slightly more at ease and considerably more relaxed, had a heightened sense of naturalness, and experienced reduced anxiety after engaging in nature photography compared with urban photography. Notably, we observed that both systolic and diastolic blood pressure dropped by many values and there were noticeable EEG changes among participants. The results suggest that a brief 5‐min nature photography activity can effectively reduce mental stress in Chinese university students.

Few studies have investigated plants’ healing effects, particularly through touch-based therapy, on older adults. As hypertension rates continue to climb worldwide, touch-based therapy for hypertension prevention has become a significant priority in public health initiatives. This study investigated the impact of tactile interaction with real grass (a landscape activity) versus artificial grass on older adults’ physical and cognitive abilities. Employing a within-subject design, we assessed the physiological and emotional effects of touching real grass versus artificial glass for 10 min. Study participants included 50 Chinese individuals, with an average age of 85.64 ± 3.72 years. Measurements included blood pressure, electroencephalogram, State-Trait Anxiety Inventory, and standard deviation (SD). Analyzing the SD data revealed that participants experienced a heightened sense of relaxation and calmness after touching real grass, compared to artificial grass. Furthermore, the participants’ brainwave patterns—measured in mean power units—exhibited an upward trend while interacting with real grass, whereas they exhibited a downward trend during the interaction with artificial grass. Moreover, the mean systolic blood pressure significantly decreased following interaction with real grass. These findings suggest that engaging with real grass through touch potentially alleviates mental stress, in contrast to the effects of artificial grass.
