Summary: A comprehensive meta-analysis of 33 studies finds that individuals with high environmental sensitivity are more likely to experience common mental health conditions — notably depression, anxiety, PTSD and avoidant personality disorder. Environmental sensitivity refers to a heightened awareness and responsiveness to sensory and emotional cues in the environment, which can increase vulnerability to stressors while also making people more receptive to positive experiences and psychological treatment.
The research suggests clinicians should routinely consider sensitivity when assessing and planning treatment, since approaches such as mindfulness, applied relaxation and other tailored strategies may be especially beneficial for highly sensitive people. With roughly 31% of the population estimated to be highly sensitive, the findings point to both increased risk and important therapeutic opportunities associated with this personality trait.
Key Facts
- Stronger risk: Higher levels of sensitivity are linked with elevated rates of depression, anxiety, PTSD and related disorders.
- Double-edged trait: Sensitivity amplifies the impact of negative experiences but also increases responsiveness to positive interventions.
- Treatment implications: Tailored interventions, such as mindfulness and relaxation techniques, may produce stronger benefits for highly sensitive individuals and help prevent relapse.

Overview of the meta-analysis
This study is the first large-scale meta-analysis to systematically quantify the link between environmental sensitivity and common mental health outcomes in adolescents and adults. By pooling results from 33 studies, the authors examined how sensitivity relates to conditions such as depression and anxiety and explored broader associations with other psychopathologies.
Sensitivity in this context is defined as an individual difference in perceiving and processing environmental stimuli — for example, sensitivity to bright lights, subtle changes in surroundings, or other people’s moods. Although personality traits like neuroticism are commonly considered in mental health research, trait sensitivity has received less attention despite evidence of its relevance. The current analysis highlights the importance of recognizing sensitivity as a distinct characteristic that can influence both risk and recovery.
The pooled results show consistent positive correlations between sensitivity and a range of mental health outcomes. Highly sensitive individuals were more likely to report symptoms of depression and anxiety, and the meta-analysis also found associations with psychosomatic complaints, obsessive–compulsive symptoms, post-traumatic stress disorder, agoraphobia, and social phobia. These relationships suggest sensitivity is a meaningful factor in understanding who may be at greater risk for certain psychiatric symptoms.
Beyond identifying risk, the study emphasizes clinical relevance: sensitivity may help predict which patients will respond especially well to psychological interventions. Techniques that reduce physiological arousal and promote emotional regulation — such as applied relaxation and mindfulness-based practices — appear promising for sensitive individuals and may also support relapse prevention.
Tom Falkenstein, a psychotherapist and PhD student at Queen Mary University of London, notes that this is the most extensive systematic review to date examining sensitivity and mental health across adolescents and adults. The meta-analysis provides the first quantitative estimate of the association, revealing moderate positive correlations between sensitivity and several mental health problems, including depression, anxiety, post-traumatic stress disorder, agoraphobia and avoidant personality disorder. Falkenstein highlights the potential for these findings to improve diagnosis and to inform more personalized treatment planning.
Michael Pluess, Professor in Developmental Psychology at the University of Surrey and Visiting Professor at Queen Mary University of London, emphasizes that while highly sensitive people show greater vulnerability to negative experiences, they are also more responsive to positive experiences and therapeutic interventions. The quality of a person’s environment, including clinical care, is therefore especially important for their long-term well-being.
The review and meta-analysis were conducted by a multidisciplinary academic team from institutions including Queen Mary University of London and the University of Surrey, pooling data to produce robust estimates of the relationships observed.

Abstract
The Relationship Between Environmental Sensitivity and Common Mental-Health Problems in Adolescents and Adults: A Systematic Review and Meta-Analysis
Environmental sensitivity is a personality trait that captures individual differences in how people respond to environmental influences. While links between common personality dimensions and psychopathology are well established, trait sensitivity has often been overlooked despite its clear relevance to mental health.
This systematic review and meta-analysis synthesized 33 studies (N = 12,697; 62.51% female; mean age = 25.35 years) to quantify the relationship between sensitivity and several mental-health outcomes. The analysis identified positive correlations between sensitivity and depression, anxiety, psychosomatic symptoms, obsessive–compulsive disorder, post-traumatic stress disorder, agoraphobia, and social phobia, with correlation coefficients ranging from r = .05 to r = .65.
Effect sizes were substantial for depression (r = .36, 95% CI = [.30, .42], p < .001) and anxiety (r = .39, 95% CI = [.34, .44], p < .001), indicating a robust association between higher sensitivity and these common mental-health problems. The findings support the value of incorporating sensitivity into clinical assessment and treatment planning and encourage further research on how the trait can inform prevention and intervention strategies.
