Effects of mindfulness and fatigue on emotional processing: an event-related potentials study

Abstract

Fatigue is a common experience in everyday life. People who experience fatigue will have more intense negative emotions, and at the same time, their positive emotions will decrease, impairing the individual’s emotional processing ability. In previous research, mindfulness meditation reduces the intensity of negative emotional stimuli. However, if individuals continue to be affected by negative emotions when they are fatigued, it is unclear whether mindfulness can buffer the negative association between fatigue and emotions. This study examined whether mindfulness meditation affects the association between fatigue and emotions, using event-related potentials (ERPs). One hundred and forty-five participants completed the experiment. They were randomly assigned to the Mindfulness or Non-mindfulness group; and they were presented with positive, neutral, or negative pictures in an emotional processing task before and after mindfulness or rest. Late positive potential (LPP) is an important indicator of emotional stimuli perceived by individuals, and positive or negative pictures can induce an increase in LPP amplitude more than neutral pictures. Our findings suggest that fatigue significantly affected individuals’ LPP amplitudes in the early, mid, and late windows in the Non-mindfulness group, specifically, the more fatigued individuals had lower LPP amplitudes, but not in the Mindfulness group. These results suggest that in a state of fatigue, mindful individuals are able to maintain responsiveness to emotional stimuli by maintaining LPP amplitude. Our study has demonstrated that mindfulness meditation, to some extent, offsets the negative association of fatigue with the neural activation of emotions.

“…Top-down regulation decreases emotional reactivity through engagement of prefrontal brain regions by means of active reinterpretation and reappraisal of the meaning of emotional stimuli. 24 It is understood that mindfulness may enact similar top-down and bottom-up regulatory processes for physical symptoms such as fatigue 25 and sleep. 26 For example, mindfulness might assist bottom-up activation by aiding in the reorientation of attentional processes to be open, curious, and accepting of present moment experiences of fatigue or sleep disturbance without judgement of embellishment.…”

Rope Skipping or Badminton? The Effect of Exercise on Sleep Quality and Fatigue in University Students

“…Among Chinese university students, this can also be attributed to academic workload and employment concerns [31]. Fatigue and sleep issues are often interrelated and are associated with impairments in physical and mental health, cognition, emotions, and well-being [7,13,19,20]. Previous studies have shown that exercise interventions can be bene cial for fatigue and sleep issues [3,8,17].…”
