The Science of Gratitude: How It Heals Your Body

Gratitude isn’t just a nice feeling—it actually changes your biology. When you regularly practice gratitude (like writing in a journal or simply noticing what you're thankful for), it sends signals through your brain that increase feel-good chemicals like dopamine and serotonin. These chemicals help regulate your mood and reduce stress. Gratitude also boosts oxytocin, which strengthens social bonds and trust. Even more amazing, gratitude can “turn off” genes linked to inflammation and disease, and “turn on” genes that support healing and repair. In short, the simple act of being grateful can lower stress, reduce inflammation, improve your immune system, and even protect your heart and brain over time.
