🌟 2. Short-Term Aftermath (Right After Exercise) After your workout, your brain rides a “neurochemical high”: - Mental clarity improves: Dopamine sharpens focus and helps you think more clearly. - Mood lift: Endorphins and serotonin create that “runner’s high” — a calm, happy, grounded feeling. - Better stress resilience: Your nervous system recalibrates, making it easier to handle daily stress. You often leave the gym or walk feeling lighter and more positive, and that’s literally your brain chemistry resetting.
