Why Personal Relationships Are Important
More info on this topic
Healthy relationships are a vital component of health and wellbeing. There is compelling evidence that strong relationships contribute to a long, healthy, and happy life. Conversely, the health risks from being alone or isolated in one’s life are comparable to the risks associated with cigarette smoking, blood pressure, and obesity.
Research shows that healthy relationships can help you:
A review of 148 studies found that people with strong social relationships are 50% less likely to die prematurely. Similarly, Dan Buettner’s Blue Zones research calculates that committing to a life partner can add 3 years to life expectancy (Researchers Nicholas Christakis and James Fowler have found that men’s life expectancy benefits from marriage more than women’s do.)

The support offered by a caring friend can provide a buffer against the effects of stress. In a study of over 100 people, researchers found that people who completed a stressful task experienced a faster recovery when they were reminded of people with whom they had strong relationships. (Those who were reminded of stressful relationships, on the other hand, experienced even more stress and higher blood pressure.)
According to research by psychologist Sheldon Cohen, college students who reported having strong relationships were half as likely to catch a common cold when exposed to the virus. In addition, 2012 international Gallup poll found that people who feel they have friends and family to count on are generally more satisfied with their personal health than people who feel isolated. And hanging out with healthy people increases your own likelihood of health—in their book Connected, Christakis and Fowler show that non-obese people are more likely to have non-obese friends because healthy habits spread through our social networks.
A survey by the National Bureau of Economic Research of 5,000 people found that doubling your group of friends has the same effect on your wellbeing as a 50% increase in income!

Depression. Loneliness has long been commonly associated with depression, and now research is backing this correlation up: a 2012 study of breast cancer patients found that those with fewer satisfying social connections experienced higher levels of depression, pain, and fatigue.
Decreased immune function. The authors of the same study also found a correlation between loneliness and immune system dysregulation, meaning that a lack of social connections can increase your chances of becoming sick.
Higher blood pressure. University of Chicago researchers who studied a group of 229 adults over five years found that loneliness could predict higher blood pressure even years later, indicating that the effects of isolation have long-lasting consequences.
According to psychiatrists Jacqueline Olds and Richard Schwartz, social alienation is an inevitable result of contemporary society’s preoccupation with materialism and frantic “busy-ness.” Their decades of research supports the idea that a lack of relationships can cause multiple problems with physical, emotional, and spiritual health. The research is clear and devastating: isolation is fatal.
