Positive psychology exercises improve heart health in weeks

A review of 18 randomized trials found that mindfulness, gratitude, and optimism training improved blood pressure and inflammation within two to three months. The most effective programs combined daily practice with regular reinforcement. Researchers suggest these interventions could complement traditional cardiovascular care.

The review examined trials enrolling 50 to 200 adults with elevated cardiovascular risk, including uncontrolled hypertension and heart failure, with participants typically in their late 50s to mid-60s. Programs ranged from six to twelve weeks and used varied delivery methods, including phone sessions, journaling with check-ins, apps, text messages, and in-person group meetings. A 12-week digital spirituality-based intervention produced one of the largest recorded reductions, lowering systolic blood pressure by 7.6 points and central aortic pressure by 4.1 points.

Hernandez noted that previous positive psychology research often failed to establish clear practice frequency guidelines. The most reliable physiological improvements came from programs with frequent participant contact, particularly an eight-week WhatsApp-based intervention combining weekly sessions with daily microtasks encouraging physical activity, dietary improvements, and medication adherence. This suggests sustained reinforcement, not just initial training, may be critical for maintaining cardiovascular benefits over time.
