Peer-reviewed research on mindfulness, workplace well-being and habit formation, including its limitations.
Mindfulness-based programs have been studied scientifically for more than 40 years. This page presents a selection of peer-reviewed studies that inform Serene Flow, what they found and where their limits lie. Evidence differs by outcome and population, and results from research settings do not automatically transfer to every organization. This page is for information only and does not replace medical or psychological care.
1. Stress, anxiety and depression
Goyal et al. (2014) · JAMA Internal Medicine Meditation programs for psychological stress and well-being: a systematic review and meta-analysis Review of 47 randomized trials with 3,515 participants. Meditation programs produced small to moderate reductions in negative dimensions of psychological stress. For mindfulness programs, the evidence was moderate for improvements in anxiety, depression and pain, and low for stress and distress. Limits: the trials mostly involved people with clinical conditions and were mostly short-term; the review found no evidence that meditation was better than active treatments such as exercise or other therapies.

Buric et al. (2017) · Frontiers in Immunology What is the molecular signature of mind–body interventions? A systematic review of gene expression changes induced by meditation and related practices Review of 18 studies on mind–body practices (for example mindfulness, yoga, tai chi, qigong and breath regulation). Overall, these practices were associated with reduced activity of the NF-κB pathway, which is involved in inflammation and is activated by chronic stress. Limits: few studies; it is unclear how the effects compare with other healthy habits such as exercise or nutrition. This is early-stage evidence. Link
2. Mindfulness at work
Vonderlin et al. (2020) · Mindfulness Mindfulness-based programs in the workplace: a meta-analysis of randomized controlled trials Mindfulness-based programs reduced employees’ stress, burnout, mental distress and somatic complaints, and improved mindfulness, well-being, compassion and job satisfaction. Effect sizes ranged from small to large (Hedges’ g = 0.32–0.77). Limits: results vary between studies and programs; workplace trials differ in design and quality, and further high-quality trials are needed. Link
Michaelsen et al. (2023) · Mindfulness Mindfulness-based and mindfulness-informed interventions at the workplace: a systematic review and meta-regression analysis of RCTs Synthesis of 91 randomized studies (about 4,900 participants in the intervention groups). The interventions showed small to medium average improvements in stress, mental health, well-being and mindfulness. Limits: short-term effects (up to 12 weeks) were more consistent than long-term effects (13–52 weeks), for which fewer studies exist; heterogeneity and risk of bias were high, so the authors call for higher-quality studies. Link
Good et al. (2016) · Journal of Management Contemplating mindfulness at work: an integrative review Integrative review proposing a framework for how mindfulness influences attention, with downstream effects on cognition, emotion, behavior and physiology, and through these on workplace outcomes such as performance, relationships and well-being. Limits: a conceptual framework rather than an effect-size estimate; the authors also set out open research questions. Link
3. Attention and the brain
Killingsworth & Gilbert (2010) · Science A wandering mind is an unhappy mind In a large smartphone-based study of adults going about their day, minds wandered during about 47% of waking moments, and mind-wandering was associated with lower reported happiness. Limits: observational design; it describes associations and does not test the effect of meditation. Link
Zeidan et al. (2010) · Consciousness and Cognition Mindfulness meditation improves cognition: evidence of brief mental training After four 20-minute sessions of mindfulness meditation training, participants improved on tests of visuo-spatial processing, working memory and executive functioning compared with a control group. Limits: small study with healthy volunteers; effects were measured right after the training; replication and longer follow-up are needed. Link
Hölzel et al. (2011) · Psychiatry Research: Neuroimaging Mindfulness practice leads to increases in regional brain gray matter density In a small MRI study, an 8-week mindfulness-based stress reduction course was associated with changes in gray matter concentration in brain regions linked to learning, memory and emotion regulation. Limits: small sample; what such changes mean for everyday functioning is not yet clear, and replication is needed. Link
4. Habits: what makes a practice stick
Lally et al. (2010) · European Journal of Social Psychology How are habits formed: modelling habit formation in the real world 96 volunteers chose a simple daily behavior (eating, drinking or activity) and repeated it in the same context for 12 weeks. For those whose progress could be modelled, reaching near-peak automaticity took between 18 and 254 days (about 66 days on average). Missing a single day did not materially affect the process. Limits: simple behaviors and volunteer participants; the observation lasted 12 weeks, so longer times are model-based estimates; more complex behaviors can take longer. Link
Gollwitzer (1999) · American Psychologist Implementation intentions: strong effects of simple plans Review of research showing that specific “if–then” plans (when, where and how one will act) help people turn intentions into action. Limits: the effect depends on how committed a person is to the goal and on the situation. Link
Wood, Quinn & Kashy (2002) · Journal of Personality and Social Psychology Habits in everyday life: thought, emotion, and action In a diary study of university students, about 43% of everyday behaviors were performed almost daily in the same context, that is, largely out of habit. Limits: self-reported data from a student sample. Link
5. Breathing
Balban et al. (2023) · Cell Reports Medicine Brief structured respiration practices enhance mood and reduce physiological arousal In a one-month randomized study, five minutes of daily breathwork improved mood. “Cyclic sighing” produced the largest mood gains and lowered breathing rate more than mindfulness meditation. Limits: short duration and self-reported mood; replication with longer follow-up is needed. Link
6. Limits, risks and schools
Van Dam et al. (2018) · Perspectives on Psychological Science Mind the hype: a critical evaluation and prescriptive agenda for research on mindfulness and meditation Critical review by mindfulness researchers pointing to inconsistent definitions, methodological weaknesses and overstated claims, with recommendations for stronger research and more careful communication. Why it matters here: we use the research in this spirit and state its limits openly. Link
Lindahl et al. (2017) · PLOS ONE The varieties of contemplative experience: a mixed-methods study of meditation-related challenges in Western Buddhists Study of experienced meditators documenting a range of challenging experiences (cognitive, perceptual, emotional and physical) that some practitioners report, and the importance of context and guidance. Limits: not a prevalence estimate; a sample of experienced practitioners from one tradition. Link
Kuyken et al. (2022) · Evidence-Based Mental Health Effectiveness and cost-effectiveness of universal school-based mindfulness training compared with normal school provision (the MYRIAD trial) Cluster-randomized trial in 85 schools; 84 schools (8,376 adolescents) were analyzed. There was no evidence that the school-based mindfulness program was superior to teaching as usual at one-year follow-up. What this means for us: the result applies to one specific 10-lesson program. It shows why programs for schools should be voluntary, age-appropriate and evaluated. Serene Flow works with students aged 13 and over. Link
