While most people are familiar with the advice to eat healthy and exercise to prevent serious illnesses like stroke and heart disease, mounting evidence suggests that social relationships may be just as important to long-term health.
Experts and researchers are emphasizing the overlooked role that social connections play not only in mental well-being but also in physical health outcomes. Sociological studies continue to reveal that a person’s relationships can have a profound impact on both their short- and long-term health.
One study cited by the American Sociological Association found that individuals with a larger number of social connections tend to live longer than those who are socially isolated. However, it isn’t just about lifespan—social health also affects the likelihood of developing life-threatening conditions.
Isolation Linked to Major Health Risks
Isolation has been identified as a contributing factor in the development of several chronic diseases. A systematic review of 19 studies conducted across 12 countries and involving nearly 1.7 million participants revealed a significant link between poor social relationships and an increased risk of stroke.
Although researchers caution that correlation doesn’t necessarily mean causation, the data suggest that strong social ties may encourage healthier lifestyles, improved mental health, and a reduction in harmful behaviors—all of which contribute to lower disease risk.
Loneliness in the U.S.: A Growing Health Concern
According to the Centers for Disease Control and Prevention (CDC), nearly one in three adults in the U.S. report feeling lonely, while one in four say they lack emotional or social support in their lives. The CDC notes that several factors can increase the risk of isolation, such as employment status, health, geographic location, and even language barriers.
Factors that may contribute to social isolation include:
- Mental health challenges
- Chronic illness or long-term disability
- Belonging to a marginalized community
- Living in rural or remote areas
- Limited transportation access
- Language differences
- History of abuse or violence
- Unemployment
- Bereavement
Populations at higher risk include:
- Older adults
- Young adults
- People living alone
- LGBTQ+ individuals
- Immigrants
The CDC stresses that taking steps to strengthen social bonds can lead to better mental and physical health. Strategies include joining community groups, seeking support services, or simply making an effort to connect regularly with friends and family.
In an era increasingly defined by digital interactions and social fragmentation, health experts are urging both individuals and policymakers to recognize social connectivity as a crucial element of preventive healthcare.
