Trait-Like Mindfulness Promotes Healthy Self-Regulation of Stress

A number of experts have described mindfulness as a naturally occurring quality in the human mind that is present to some degree in all people, even without training in mindfulness or meditation. This study examined whether trait mindfulness is associated with reduced stress response activation and enhanced self-regulatory activity with recurrent stress. Self-ratings of mindfulness and continuous measures of physiological reactivity before, during, and after an interview about a recurrent stressful issue were collected from 47 undergraduate participants to examine our primary objective. Findings indicated that mindful individuals were less likely to engage in metabolically costly physiological activation in response to an emotionally challenging task, but were more likely to engage parasympathetic responding following the task, a response which is associated with effective downregulation following stress. Results from our study suggest that Bnatively mindful^individuals have the ability to engage self-regulatory physiological responding associated with improved adaptability and flexibility in a changing environment. Thus, mindfulness may be associated with physical indices of emotional well-being. Furthermore, our data adds evidence for the validity of self-report measures of mindfulness.

“…The validity of the use of specific patterns of autonomic activity as an indicator for specific emotions is disputed. There are certainly characteristics of sympathetic/parasympathetic activity and respiration that are correlated with certain emotional states such as anxiety or happiness (Kop et al 2011). We propose that negative mood states such as stress, anxiety, and depression cause sympathetic activation that is due to widespread depolarization throughout the brain and body, and that slow, deep breathing and meditation lead to parasympathetic activation due to widespread inhibition and hyperpolarization.…”

Understanding the autonomic nervous system and homeostatic changes associated with emotions remains a major challenge for neuroscientists and a fundamental prerequisite to treat anxiety, stress, and emotional disorders. Based on recent publications, the inter-relationship between respiration and emotions and the influence of respiration on autonomic changes, and subsequent widespread membrane potential changes resulting from changes in homeostasis are discussed. We hypothesize that reversing homeostatic alterations with meditation and breathing techniques rather than targeting neurotransmitters with medication may be a superior method to address the whole body changes that occur in stress, anxiety, and depression. Detrimental effects of stress, negative emotions, and sympathetic dominance of the autonomic nervous system have been shown to be counteracted by different forms of meditation, relaxation, and breathing techniques. We propose that these breathing techniques could be used as firstline and supplemental treatments for stress, anxiety, depression, and some emotional disorders.

“…In our study Alpha 2 activity increased meaningfully with response to sad emotion more specifically in Fz (mid frontal zone) there are few studies conducted with respect to Fz area in the past (15). In Kops's study, electrophysiological responses like HRV (Heart Rate Variability) related to emotions were assessed (27). It has been demonstrated that in emotional disorders, alpha variability occurs in frontal regions.…”

Background: One of the prime areas in psychiatry is concerned with assessing emotions. Assessment of physiologic responses can be attained by various approaches. One of them is analyzing Electroencephalography (EEG). Objectives: In current study, we aimed to assess Alpha wave in frontal region after inducing specific emotion by showing evocative video clips. Materials and Methods: After a baseline in Eye Open situation recording, we showed 5 video clips that each induced specific emotions from five major ones (Neutral, Happiness, Sadness, Anger, Fear) to 66 healthy individuals, including 33 males and 33 females between 20 -40 years old and EEG recording was continued simultaneously. Then, we analyzed their brain waves. Absolute power of Alpha wave Bands (Alpha 1 and Alpha 2) in frontal region (FZ, F4, F3) was analyzed via Wilcoxon test. Results: With respect to eye open situation, all video clips made significant change in Alpha 2 in F3 and F4 (P < 0.001) but not in Fz except for sadness. Sad inductive clip made a significant increase in Alpha 2 in Fz, also Alpha 1 in F3 and F4 (P < 0.001). Fz had no significant variability in all other emotions. Conclusions:The most trenchant impact with respect to Alpha band was sadness, and the most exclusive finding in FZ was Alpha 2. Nonetheless, in two other zones (F3, F4), Alpha 1 was exclusive and Alpha 2 variability was non-exclusive. It appears plausible that sadness activates neuron groups, which are involved in generating Alpha waves.
