Does Heartfulness meditation improve stress-related neuroendocrine markers and emotional states in young adults?
Heartfulness meditation significantly modulates stress-related neuroendocrine markers by increasing oxytocin and endorphins and reducing cortisol, presenting a promising non-pharmacological intervention for stress resilience.

BACKGROUND: Chronic stress disrupts the neuroendocrine system, leading to imbalances in neurotransmitters and stress hormones such as oxytocin, β endorphins and cortisol, contributing to mood disorders and poor emotional regulation. Complementary and alternative practices like meditation have shown promising results in stress regulation and mood elevation. Heartfulness (HFN) meditation, rooted in yogic traditions and incorporating yogic transmission, is an emerging technique to improve emotional resilience and hormonal homeostasis. Therefore, this study aimed to evaluate the effects of HFN meditation on oxytocin, β-endorphins, and cortisol. It also evaluated the changes in meditation depth using validated psychometric tools. METHODS: A randomized controlled trial was conducted. Participants were divided into experimental and control groups. The experimental group practiced guided HFN meditation for 30 days. Following this, a crossover design was implemented in which, the control group participants were now given the intervention of HFN meditation. Biochemical markers (serum oxytocin, β-endorphins, cortisol) were measured at day 30, and day 60. Psychometric assessments included the Meditation Depth Questionnaire and the Positive and Negative Affect Schedule (PANAS). RESULTS: HFN meditation significantly improved meditation depth (ΔM = -14.87, 95% CI -23.61,-6.13, P = .001, r = 0.333) and positive affect (ΔM = -8.48, 95% CI -12.03,-4.93, P < .001, r = 0.29), while reducing negative affect (ΔM = 7.70, 95% CI 3.81, 11.60, P < .001, r = 0.21). Oxytocin and endorphin levels increased (oxytocin ΔM = +88.18, P = .003, r = 0.355 and endorphin ΔM = +94.83, P = .003, r = 0.357), and cortisol decreased (ΔM = -133.55, P < .001, r = 0.661). After crossover, the control group exhibited similar improvements. Negative correlations were found between cortisol and both oxytocin and β-endorphins. CONCLUSION: HFN meditation significantly modulates stress-related neuroendocrine markers and enhances positive emotional states. By increasing the levels of these happy hormones and reducing cortisol, HFN presents a promising non-pharmacological intervention for improving mental health and stress resilience.
Philip et al. (Fri,) conducted a rct in Healthy young adults (n=60). Heartfulness (HFN) meditation vs. No meditation was evaluated on Serum cortisol levels at day 30 (r = 0.661, p=<0.001). Heartfulness meditation significantly reduced serum cortisol levels and increased oxytocin and beta-endorphin levels compared to no meditation in young adults.
