Bipolar Affective Disorder; Remission in

This study aims to explore how six short, 15-minute self-regulation techniques affect the body and brain in a female adult with ADHD and stabilized bipolar disorder. The techniques being tested include: * Aerobic exercise * Controlled breathing (cyclic sighing) * Aromatherapy with lavender essential oil * Listening to specific music (Solfeggio 528 Hz) * Virtual reality relaxation with forest imagery * Emotional Freedom Technique (EFT) tapping One session of quiet sitting with eyes open serves as a comparison. The participant will attend one 15-minute session per week for each technique. Before and after each session, the researchers will measure: * Heart rate and heart rate variability * Stress levels using Subjective Units of Distress Scale * Mood using a questionnaire * Blood pressure * Brain activity using EEG * Memory performance with a simple test (N-back) * Pain sensitivity The goal is to understand how these short, non-invasive techniques influence both physiological and psychological responses. Sessions are safe, short, and designed to involve minimal risk. The findings may help guide future research on relaxation and exercise strategies for people with ADHD and bipolar disorder.
