Many adults find their social circles shrinking as they age. Whether due to retirement, the loss of loved ones, limited mobility or other reasons, this often leads to loneliness. And it’s a bigger problem than you might think.
“A recent study found that a third of adults over 50 in the U.S. experience significant loneliness,“ notes Robert L. Trestman, MD, PhD, chair of Carilion Clinic Psychiatry and Behavioral Medicine.
But being lonely isn’t just about having fewer people around—it’s about feeling disconnected and lacking meaningful relationships. And that can take a real toll on your body and mind.
Health risks of loneliness
“Data links loneliness to negative effects on our health, especially in those over 50,” says Dr. Trestman. This can include impacts on:
- Heart health: Loneliness can raise your risk for problems like heart disease and high blood pressure. Being lonely causes stress, which puts strain on your heart over time.
- Memory and brain function: Socializing helps keep your brain active. Spending too much time alone can speed up memory loss and increase the risk of dementia.
- Immune system: Loneliness can weaken your immune system, making it harder to fight off illness. It also increases inflammation in the body, which can make chronic conditions like arthritis worse.
- Mental health: People who are lonely are more likely to suffer from depression and anxiety. These mental health issues can make it harder to stay physically healthy or manage existing health problems.
- Sleep: Loneliness can cause sleep problems, like trouble falling or staying asleep. Poor sleep can affect everything from mood to balance and coordination.
How can older adults stay connected?
There are many steps older people can take to stay connected and improve their health and happiness:
- Stay in touch: Call, text or video chat with friends and family regularly. Even a short conversation can make a big difference.
- Join a group: Look for book clubs, interest groups or fitness classes in your area. Many free community events are available.
- Volunteer: Helping others is a fulfilling way to feel connected.
- Try something new: Learning a new skill or hobby can boost confidence and create new opportunities to meet people.
- Get outside: Fresh air is important. A walk in the neighborhood or spending time at a local park can provide a mood boost and chance for socializing.
If you have concerns about your mental or physical health, make an appointment with your doctor.
