Research shows gratitude journaling three times weekly for just two weeks significantly increases positive emotions while decreasing negative ones. This practice goes beyond simple thankfulness, activating brain reward pathways and increasing happiness-related neurotransmitters. Using diverse prompts prevents adaptation, while focusing on specific details (like "grateful for my spouse making coffee" versus general appreciation) creates stronger neural connections. Consistency rewires your brain toward positive thinking, even during challenging times—making this simple practice transformative for mental health and relationships.
