Comparative Effects of Meditation, Nature Exposure, and Digital Activities on Physiological and Perceived Stress
Comparative Effects of Meditation, Nature Exposure, Digital Scrolling, and Reading on Physiological and Perceived Stress: A Non-Randomized Controlled Study
The present study aims to compare the effects of meditation, nature exposure, digital scrolling, and reading on physiological and perceived stress. Participants will undergo a baseline assessment including the Five Facet Mindfulness Questionnaire (FFMQ), a visual analogue scale (VAS) for anxiety, and salivary cortisol collection at 8:30 a.m, prior to cortisol peak. Participants will then engage in one of four activities: guided meditation, a walk in a forest environment, digital scrolling on a smartphone, or reading a neutral text. Following the activity, salivary cortisol will be collected again and anxiety will be reassessed using the VAS. The study will evaluate changes in cortisol levels, perceived stress and perceived anxiety across the four conditions and explore the potential moderating role of baseline mindfulness traits.
The central research question of this study is whether different experiential conditions elicit distinct psychophysiological responses, as reflected by changes in perceived stressm salivary cortisol and perceived anxiety and therefore this investigation could improve the understanding of how different experiential contexts influence short-term stress regulation.
調査の概要
詳細な説明
Stress is a global phenomenon. Chronic exposure to stress is associated with adverse physical and mental health outcomes, including cardiovascular disease, anxiety, depression, sleep disturbances, and impaired cognitive functioning. Consequently, identifying accessible and effective strategies for stress reduction has become a major public health priority. To explore new ways of managing it is of crucial relevance, therefore the effects of meditation, nature exposure, digital scrolling, and neutral reading on physiological and perceived stress will be investigated.
Participants will be allocated to one of 5 intervention groups: (1) guided meditation, (2) guided meditaiton (3) forest walking, (4) smartphone scrolling, or (5) reading a neutral text.
All study procedures will take place in the morning to account for the circadian rhythm of cortisol secretion. At baseline, participants will complete demographic and study-related assessments, including the Five Facet Mindfulness Questionnaire (FFMQ) and a VAS measuring current stress and anxiety levels. A baseline saliva sample for cortisol determination will be collected at 8:45 a.m., shortly before the expected morning cortisol peak.
Participants will then engage in their assigned activity. The 2 meditation groups will complete a 20-minute guided meditation session using two different meditation techniques. The forest exposure group will undertake a 20-minute walk in a forest environment. The digital activity group will spend 20 minutes scrolling on a smartphone, while the control group will spend 20 minutes reading a neutral text. The duration of the intervention will be standardized across all groups.
Immediately following completion of the assigned activity, participants will undergo a second assessment at approximately 9:00 a.m. A post-intervention saliva sample will be collected for cortisol analysis, and participants will again complete the VAS for anxiety and stress. Salivary Cortisol and DHEA levels will be evaluated at 4 time points the above already mentioned two, and in the evening and before sleeep.
The primary objective of the study is to compare changes in perceived stress. Secondary objectives include evaluating changes in cortisool levels, DHEA, perceived anxiety and exploring the relationship between baseline mindfulness traits, as measured by the FFMQ, and physiological and psychological responses to the interventions.
The study aims to provide preliminary evidence regarding the immediate effects of contemplative practice, exposure to natural environments, and digital engagement on stress-related outcomes in healthy adult participants

参加者グループ / アーム |
介入・治療 |
|---|---|
|
実験的：Experimental
Participants in this groups will undergo a mindfulness based intervention.
The meditation tecniques will differ one from the other for focused breathing, body relaxation, emotional awareness and acceptance exercises.
The intervention consists of 1 in person session of 20 minutes.
|
The intervention consists of 1 in person session of mindfulness of 20 minutes.
|
|
介入なし：No Intervention
Participants in this group will not receive any psychophysiological interventions during the study.
This group serve as a passiva control group to evaluate the effectivness of the mindfulness-based intervention by comparing pre and post intervention measures.
|
|
|
アクティブコンパレータ：Forest bathing
The forest bathing group will act as a an active control group.
Forest bathing is known to exert psyhophysiological effects on the stress response system, allowing to evaluate different stress management techniques
|
Participants engaged in guided forest immersion including mindful walking, sensory awareness, meditation, and nature-based contemplative activities.The intervention consists of 1 in person session of 20 minutes.
|
|
アクティブコンパレータ：Scrolling
Scrolling group will act as an active control group to evaluate the absence of the positive psychophysiological stress response.
The intervention consists of 1 in person session of 20 minutes.
|
Strolling consisted of a slow, relaxed walk in a natural environment without specific mindfulness or sensory-awareness instructions.

メジャーの説明 |
時間枠 |
|---|---|---|
|
Change in perceived stress.
時間枠：Baseline and immediately after the single intervention session (same day).
|
Change in perceived stress measured using a Visual Analog Scale for Stress (VAS-Stress), ranging from 0 to 100, where 0 indicates no perceived stress and 100 indicates the highest level of perceived stress imaginable.
The outcome will be calculated as the difference between post-intervention and pre-intervention scores.
Negative values indicate a reduction in perceived stress following the intervention.
