Quiet time can be lovely. Loneliness is different. It is the painful feeling of not being connected. New research suggests that feeling matters for how we age.
What the newest research says
In July, Harvard Health shared a large study from the Journal of Personality and Social Psychology. Researchers pooled 11 earlier studies of 175,070 adults aged 50 and older in 18 countries. People who felt lonely had worse thinking and memory over time and a shorter life. This held even after the researchers accounted for how few social contacts people had. Each 10 percent rise in loneliness scores went with an 8 to 9 percent higher chance of moving from normal thinking to mild memory trouble.
Here is the part that surprised many: spending time alone, by choice or by life events, was not consistently linked to thinking problems. It had only a weak link to early death. The study's authors suggest that feeling connected may matter more than how many contacts you have. This study is observational. It shows a link. It does not prove that loneliness causes these problems.
What the CDC says
The CDC says about 1 in 3 U.S. adults report feeling lonely. About 1 in 4 say they lack social and emotional support. It adds that older adults are more at risk for social isolation. The CDC links isolation and loneliness with a higher risk of heart disease, stroke, type 2 diabetes, depression, anxiety, dementia and earlier death. It also says that being connected helps protect against serious illness.
Simple ways to connect
- Join a group. Harvard Health suggests clubs, volunteer jobs and classes that match your interests. Online or in person both work.
- Start your own. A book club, trivia or game night, or a bird-watching group.
- Make a weekly date. A walk with a neighbor. Coffee with a friend. A phone call every Sunday.
- Share a meal. Cook a big pot of soup and invite someone.
- Say yes. When someone invites you, go for 30 minutes. You can leave if you wish.
Keep it going
Harvard Health suggests that if you cannot find the right group, start one. A regular get-together gives you something to look forward to. Ask a friend to share the work. One person brings the snacks. Another picks the game or the book. Keep it small and keep it regular.
It also helps to remember that feeling connected is the goal. A few close, warm relationships may do more for you than a big crowd.
A gentle four-week plan
- Week 1: Call one person you have not spoken to in a while.
- Week 2: Say hello to a neighbor or a store clerk. Short chats count.
- Week 3: Visit a class, library event or club once.
- Week 4: Pick one group or friend and set a regular day.
If getting out is hard, Harvard Health says online clubs and classes can work too. What matters is a regular, real connection.
If you are feeling very low
Loneliness and sadness can go together. Talk to your doctor if you feel down for more than a couple of weeks, or if you feel hopeless.
