Mindfulness is a practice that involves focusing on the present moment with calm awareness. It is widely used as a method to manage stress, improve emotional well being, and build mental clarity. Many students face academic stress due to exams, assignments, and deadlines. Without proper strategies, this stress can affect their health and performance. This study explores how mindfulness can help reduce stress among students in the English Department at UIN Ar-Raniry. This research used a qualitative descriptive method. Ten students from the English Department who had taken the Advance Language Skills course and practiced mindfulness were chosen as participants through purposive sampling. Data were collected using semi structured interviews and analyzed using thematic analysis to find patterns and themes in their responses. The study found that mindfulness had several positive effects. Emotionally, it helped students feel calmer, more relaxed, and less anxious. Cognitively, it improved their focus, memory, and decision making. Behaviorally, students used mindfulness activities like deep breathing, meditation, walking, or listening to music to manage stress. Both short term and long term benefits were observed, including better sleep, stronger emotional control, and increased mental strength. The results show that mindfulness is an effective strategy to reduce academic stress. It supports emotional balance, improves thinking ability, and encourages healthy habits. Students who regularly practice mindfulness become more resilient and confident in handling academic challenges. These findings suggest that mindfulness should be promoted in educational settings to support students mental health and academic success.
