Simple practices such as mindfulness, gratitude journaling, and optimism training may improve several markers of cardiovascular health within a matter of weeks. A recent study found that these positive psychology interventions were consistently associated with improvements in blood pressure, inflammation, and other heart disease risk factors. Because some of the benefits appeared to be connected with healthier behaviors, including better eating habits and increased physical activity, the researchers said continued reinforcement may be necessary to maintain progress over time.
Rosalba (Rose) Hernandez, a professor of social work at the University of Illinois Urbana-Champaign, led the research team. The group reviewed results from 18 randomized controlled trials that tested positive psychology and mindfulness interventions designed to improve mental or physical health.
How the Heart Health Programs Worked
The programs varied widely in how they were delivered. Some relied on structured phone sessions, journaling paired with brief check-ins, or digital tools such as apps and text messages. Others involved interactive in-person group meetings or hybrid approaches that combined face-to-face activities with online tools and virtual sessions.
