The Combined Buddhist Mindfulness Training Enhances Executive Functions and Psychological Well-being without Influencing Vagal Tone
摘要
Extended mindfulness sessions in Theravada Buddhist retreats can be challenging for beginners. This study examined whether a 1-hr daily Buddhist mindfulness training (BMT) program combining chanting, moving, and breathing meditations could improve executive functions, psychological well-being, and resting heart rate variability (HRV) in young adults within the framework of the neurovisceral integration model.
MethodFifty young adults were equally divided into the BMT or an active no-training (NT) group. Working memory, attention, inhibitory control, psychological well-being, and resting physiological measures (heart rate, HRV, blood pressure (BP), and respiratory rate) were assessed before and after the 8-week intervention.
ResultsThe BMT group showed significant improvements in awareness (d = 1.05) and happiness (d = 0.78), with reductions in anxiety (d = 0.78) and depression (d = 0.64) (p < 0.005). They also demonstrated improved backward memory (p < 0.05, r = 0.46), reduced reaction time variability (p = 0.002, d = 0.69), and a smaller reduction in sustained attention task efficiency compared with the NT group (BMT: p = 0.02, d = 0.46; NT: p < 0.001, d = 0.82). A nonsignificant trend toward reduced incongruent Stroop response time was observed in the BMT group (p = 0.07), whereas NT demonstrated a similar but smaller reduction. Physiologically, BMT reduced resting diastolic and mean arterial BP across the 15-min resting period (p < 0.01, d = 0.54–0.66), whereas NT showed a reduction only at 10 min. Only the BMT group showed an increase in 15-min resting ln LF-HRV (p < 0.05, d = 0.44).
ConclusionsDaily BMT practice over 8 weeks improved executive functions and psychological well-being without altering cardiac vagal tone in young adults, highlighting its potential as an engaging mindfulness-based intervention for novice practitioners.
