Countless studies have shown maintaining
rich, meaningful relationships and social interaction is a key ingredient to a
healthy life. But did you know that it
also can lead to a healthier brain? Along with physical
exercise, nutrition, brain
training, and lifelong
learning, social interaction has been found to greatly
impact cognitive sharpness and brain health.
A rich social network provides sources
of support, reduces stress, combats depression, and enhances intellectual
stimulation. Studies have shown that those with the most social interaction
within their community experience the slowest rate of memory decline. Happy
marriages or long-term relationships and having a purpose in life have shown
significant positive effects against age-related cognitive impairment.
Researchers at
Brigham Young University analyzed data from 70 studies that
included more than 3 million people and found that loneliness and social
isolation increased the risk of premature death by about 30 percent. In fact,
the scientists found that feeling lonely is as dangerous as smoking 15
cigarettes a day.
On
the other hand, having meaningful relationships helps protect the immune
system, reduces stress, and decreases
the risk of developing dementia.
”Researchers have found that having even
one close friend that you can confide in can extend your life by as much as 10
years,” says sociologist and relationship coach Jan Yager, PhD, author of Friendshifts.
But socializing doesn't just help prevent
mental disease, it can also help us remember more, and think more
clearly. Oscar Ybarra of Michigan University monitored phone usage data from 3600 people,
analyzing how long they talked and to whom. Even while controlling for other
variables, researchers uncovered a positive
relationship between social engagement and mental performance.
Other research
shows that people who are regularly engaged in social interaction maintain
their brain vitality. But again, the combination of physical and mental activity
with social engagement, and a brain-healthy diet is more effective than any of
these factors alone. So rekindle some friendships, volunteer in your community,
get out and mingle; it is not only good for your soul, but good for a healthy
brain!
