This interview podcast episode of "The Happiness Lab" features psychologist Ethan Kross, author of "SHIFT," discussing emotion regulation. The episode begins with Kross's personal story, inspired by his grandmother's resilience after World War II, leading into a historical overview of emotion regulation techniques. Kross then presents practical strategies, including using sensory stimuli (music, touch), managing attention (distraction, re-engagement), and gaining perspective (self-talk, mental time travel). He emphasizes the importance of physical distance from stressors and the impact of emotional contagion in shaping our emotional state and those around us. Listeners gain actionable tools to manage negative emotions, such as using upbeat music to counter sadness or creating emotionally supportive spaces.
