New research has found that looking after your mental wellbeing could also help protect your heart.
Public Health Wales commissioned experts at Cardiff Metropolitan University to examine the evidence linking mental wellbeing and heart health. Their rapid review looked at peer-reviewed studies published between 2005 and 2025 and identified 12 high-quality studies exploring the connection.
The findings show that people with better mental wellbeing are more likely to have healthier hearts. In particular, the evidence found lower rates of cardiovascular death and reduced risk factors such as high blood pressure and unhealthy cholesterol levels among those reporting higher wellbeing.
The strongest and most consistent links were seen in adults aged over 50. For younger people, the picture was more mixed, with lifestyle factors such as diet, smoking and physical activity playing a larger role. However, the review did find that young people who reported a strong sense of belonging and social connection were more likely to have better heart health.
Researchers say there are biological reasons behind the link. Stress hormones such as cortisol and adrenaline can damage the cardiovascular system over time. Lower stress levels may therefore help protect the heart. Social connection may also play a part, as it is linked to increased levels of oxytocin – sometimes known as the “bonding hormone” – which can help buffer the effects of stress.
The report suggests that doctors and healthcare services should treat mental wellbeing as a central part of overall health, rather than an optional extra. It encourages clinicians to ask patients about their wellbeing, measure it where appropriate and signpost people to support as part of a more holistic approach to preventing heart disease and stroke.
Emily van de Venter, Consultant in Health Improvement at Public Health Wales, said the findings underline that good mental wellbeing is “not a nice to have” but fundamental to health and quality of life.
Dr Britt Hallingberg, who led the work at Cardiff Metropolitan University, said the research highlights the importance of considering wellbeing in efforts to prevent cardiovascular disease, and called for further studies to explore how improving wellbeing over time might reduce heart risks.
Heart disease and stroke remain among the leading causes of death in Wales and across the UK. The review adds to growing evidence that prevention is not just about medication and diet, but also about strengthening community support, reducing stress and helping people feel connected and supported in their daily lives.
