Research from the Wheatley Institute reveals that regular involvement in religious communities is associated with longer life expectancy and better physical and mental health, based on a comprehensive analysis of over 1,000 studies.
A report released on October 10, 2023, by the Wheatley Institute at Brigham Young University and Duke University highlights significant correlations between religious participation and improved health outcomes. The study aggregated data from 1,069 high-quality research studies, providing a comprehensive overview of how religious involvement influences both physical and mental health.
The findings indicate that individuals who engage regularly in religious activities are less likely to experience premature death, struggle with addiction, or suffer from chronic diseases such as cardiovascular ailments and cancer. The report suggests that the benefits of religious participation significantly outweigh any potential negative impacts, with positive health-related findings outnumbering negative ones by a ratio of 7 to 1 for physical health and 10 to 1 for mental health.
Key Findings
Loren Marks, a professor of family life at Brigham Young University and one of the report’s authors, emphasized the rarity of such favorable ratios in social science research. The report suggests that various elements of religious involvement—such as health codes, community support, and spiritual beliefs—contribute to these health benefits. For instance, nearly 98% of the highest-quality studies on smoking found that religious individuals are less likely to smoke, and over 90% of studies on substance abuse indicated that those who are religious tend to struggle less with addiction.
The term “religious involvement” is defined in the report as active participation in a faith tradition, particularly among individuals who attend worship services weekly or more consistently over time. Marks noted that occasional attendees do not experience the same health benefits, and that these advantages are unique to religious engagement when compared to other social activities, such as political affiliations or social clubs.
Complementary Role of Religion
Marks cautioned that while religion can have positive health implications, it should not be viewed as a replacement for professional medical advice or treatment. He pointed out that there are instances where religious beliefs might detrimentally affect health, such as when small congregations resist vaccinations, which can result in outbreaks of preventable diseases. “Religion should complement, not replace, competent medical and mental health professionals,” Marks stated.
The Wheatley report builds on previous research compiled in the “Handbook of Religion and Health” by scholars from Duke and Harvard, which has been analyzing the relationship between religion and health for over two decades. This latest report on physical health follows an earlier publication focusing on mental health, and together they form part of a broader series titled “Religion and Human Flourishing.”
Contextualizing the Findings
The timing of this report is significant, as it emerges during a period marked by rising suicide rates in the United States and a growing sense of social isolation among many Americans. The report cites alarming statistics that indicate 40% of the U.S. population is physically inactive, contributing to increasing rates of obesity, heart disease, and diabetes. Against this backdrop, the authors suggest that religious communities may offer valuable resources for promoting individual and communal well-being.
Marks remarked on the unprecedented potential of religion as a source of health benefits, stating, “What we’re seeing here is something almost unprecedented in terms of a potent source for health.”
Mental Health Insights
In the realm of mental health, the report reveals that 961 studies identified a positive correlation between religious participation and mental well-being, while only 101 studies found harmful effects. Those who are religious often report lower risks of suicide, healthier coping mechanisms for stress, and greater overall life satisfaction. Marks highlighted the importance of social involvement, stating, “We need other people like we need air; social involvement is very important in any context.”
However, the report also acknowledges exceptions to this trend, particularly concerning mental health disorders like bipolar disorder and schizophrenia, where some studies suggest that religion may not provide the same benefits.
Preventive Health Behaviors
Religious individuals are also more likely to engage in preventive health behaviors, such as adhering to recommended screenings and following treatment plans. The report notes that while 60 studies found positive links between religiosity and preventive health behaviors, 33 studies reported negative correlations. In some cases, religious beliefs may lead individuals to forgo medical advice in favor of spiritual remedies.
Diet and Lifestyle Factors
The report examines dietary practices influenced by religious beliefs, noting that many faith traditions have specific health codes that can promote better physical health. For example, dietary restrictions observed by Jews, Muslims, and certain Christian sects, as well as practices like fasting which are common in many religions, have been linked to improved health outcomes. However, the social aspects of religious gatherings can sometimes lead to unhealthy eating habits, such as the consumption of high-calorie foods at communal events.
Cardiovascular and Cognitive Health
Religious participation is associated with personality traits, such as agreeableness and conscientiousness, which are believed to contribute to better cardiovascular health. Additionally, approximately 28 out of 38 studies indicated that involvement in religious activities may reduce the risk of Alzheimer’s disease and dementia, potentially due to increased social engagement and cognitive stimulation.
Substance Abuse Prevention
The report found that 94% of studies showed a correlation between religious participation and lower rates of substance abuse. Faith communities often foster strong family structures and parental involvement, both of which are linked to reduced addiction risks. Furthermore, religious experiences can activate brain reward systems in ways similar to addictive substances, which may help individuals manage cravings.
Policy Implications
In light of these findings, the authors recommend that healthcare providers and social service organizations consider incorporating faith-based support into their offerings and collaborate with religious organizations on issues such as addiction and suicide prevention. Marks noted, “When done well, everyone wins—public health, medicine, and the faith community all benefit from healthier and stronger congregants.”
