A new study by the University of North Carolina found that social ties are just as important for an individual’s health as exercising and healthy eating. The study analyzed data from age groups ranging from teenagers to seniors, and found that people who had more social ties at a young age were healthier later in their life. The study also found that social needs are different among different age groups. Teenagers need large social groups, but as people age, strong social ties are more important than a large social network. The study also found that for older adults, social isolation has a significant effect on the development of high blood pressure. The study suggests that doctors and other health workers enhance their efforts to help their patients understand the importance of social bonds.
