Background: Working women frequently encounter high stress levels due to the combined demands of professional duties and household responsibilities. Emotional fatigue, often underestimated, plays a critical role in reducing well-being and work-place productivity. Objective: This study investigates the effectiveness of mindfulness techniques in reducing fatigue and alleviating stress among working women. Method: A qualitative case study was conducted with five professional women who also manage domestic roles. Data were collected through in-depth interviews and observations during a series of mindfulness sessions. Result: Fatigue was found to stem not only from workplace demands but also from emotional strain at home. Participants who felt unappreciated, described as experiencing a hypo emotional tank, tended to carry negative emotions into their work, increasing stress and lowering performance. After mindfulness practice, most participants reported improved emotional balance, enhanced self-worth, and noticeable reductions in fatigue and stress. Conclusion: Mindfulness practices help working women manage stress and fatigue by fostering self-awareness and emotional resilience. Originality/Value: This study offers a significant contribution to clinical psychology and occupational health psychology by revealing the qualitative dynamics of the hypo emotional tank, namely the emotional strain arising from unacknowledged domestic burdens, alongside the therapeutic efficacy of Mindfulness Based Stress Reduction (MBSR) in restoring self worth and emotional equilibrium. By examining stress and fatigue management among career women balancing professional and domestic roles, this research addresses a critical yet underexplored dimension of workplace well being. These findings enrich the evidence based psychological literature and serve as a strategic reference for mental health practitioners, organizational counselors, and human resource managers in designing and implementing workplace mindfulness interventions to support women psychological well being and job performance.
