Amplify your gratitude practice with Waveflow’s gratitude community. Waveflow offers creative daily journaling prompts and an opportunity to celebrate and visually share your gratitude journey with your family and friends too. We apply the latest science to our gratitude framework. Expressing gratitude consistently with a community is a superpower, improving everything from our feelings of social connection to presence-based awareness. To maximize the effects of the practice, we guide our community through a thoughtful rotation of gratitude themes including: gratitude for the environment, gratitude for other people, and gratitude for ourselves. Sharing gratitude can cause synchronized activation in different parts of our brains, illuminating reward pathways and the hypothalamus. Gratitude can boost serotonin and trigger our brain stems to produce dopamine, our ‘pleasure’ neurotransmitter. In short, the more consistently we practice gratitude, the better we feel. Waveflow helps users to deepen their gratitude practice by offering features including accountability buddies and the chance to ‘follow’ friends and family along their gratitude journey. Accountability keeps us true to the practice, because consistency in a gratitude practice (finding something good, even when it’s hard) is necessary to enrich our lives in the most helpful way possible. This way, we garner inspiration and joy from our family and friends’ reflections too. Consistently celebrating and sharing the light in our lives has the power to change the way we see the world. Download Waveflow today and encourage a friend or family member to join you on your daily gratitude journey.
