Midlife often reshapes our closest relationships. Children grow up and move out. Some marriages end after decades. Friends move away, get busy with their own families or pass away. Work friendships fade after a job change or retirement. Any of these can leave a quiet, lonely gap.
Loneliness is not just a sad feeling. It is linked to depression, heart disease, stroke, dementia and early death. The good news is that connection can be rebuilt at any age, often through small, regular steps. This guide is part of our midlife guide.
Key points
- In the U.S., the divorce rate for people 50 and older doubled from 1990 to 2010. Nearly 40% of people who divorce are now 50 or older.1
- The World Health Organization estimates that loneliness is linked to about 871,000 deaths a year worldwide, about 100 every hour.2
- About 1 in 3 U.S. adults say they feel lonely. Divorce, job loss and the death of a loved one are known risk factors.3
- Adults who often feel lonely are more than twice as likely to develop depression.4
- Small, steady contact helps. Counseling can help you through separation, an empty nest and other big changes.
Signs that loneliness is affecting you
Loneliness is the painful gap between the connection you want and the connection you have. You can feel lonely in a full house or a long marriage. Being alone is not the same as being lonely, but living alone is a risk factor.3
Signs to notice:
- You go days without a real conversation.
- You feel left out, or that no one really knows you.
- Evenings and weekends feel empty or hard to fill.
- You turn down invitations, then feel worse.
- You lean on TV, your phone, food or alcohol to fill time.
- Your sleep, appetite or energy have changed.
- You feel low, irritable or hopeless.

Why it happens in midlife
Divorce later in life. "Gray divorce" means divorce at age 50 or older. Researchers at Bowling Green State University report that the gray divorce rate doubled between 1990 and 2010, then leveled off in the past decade.1 Divorce after many years can mean losing a partner, a home, shared friends, in-laws and daily routines all at once.
The empty nest. When the last child leaves home, many parents feel proud and free. Others feel a deep sense of loss, especially if parenting was the center of daily life. Many feel both. Couples may find they have to get to know each other again.
Shrinking circles. Friends move, caregiving and work take over, and health problems can make it harder to get out. Life transitions such as divorce, job loss and the death of a loved one all raise the risk of loneliness and isolation.3 So do chronic illness, depression and long-term disability.3
Hearing loss. When conversations become hard to follow, people may slowly pull back from groups and gatherings. See hearing loss and loneliness.
How loneliness affects health
The U.S. Surgeon General has reported that poor social connection is linked to about 29% higher risk of heart disease and 32% higher risk of stroke. In older adults, long-term loneliness and isolation are linked to about 50% higher risk of dementia.4 Isolation is linked to a 29% higher risk of early death.4
A large review of 148 studies found that people with stronger social ties were about 50% more likely to be alive at follow-up than people with weaker ties. That effect was similar in size to quitting smoking.5
Loneliness and depression feed each other. In a 12-year study of adults 50 and older in England, people who were lonelier at the start had worse depression symptoms later. The researchers estimated that about 11% to 18% of depression cases might be prevented if loneliness were removed.6
The WHO also links loneliness and isolation with diabetes and cognitive decline.2 For more, see health effects of loneliness and heart, brain and mood.
What helps
Small, regular contact
Limited researchA weekly phone call, a standing coffee date or a regular class builds connection over time. Research strongly links social ties with health, but trials of specific programs are still limited. See finding connection.
Treating depression
Strong evidenceIf loneliness has turned into depression, talk therapy, medicine or both can help.7 Take our depression test and see depression treatment.
Counseling for big changes
A counselor can help you grieve a marriage, handle conflict with an ex, or plan a new life after children leave. Interpersonal therapy focuses on life changes and relationships. See finding a therapist.
Hearing care
PromisingIn the ACHIEVE trial of adults 70 to 84 with hearing loss, hearing care improved loneliness and the size and quality of social networks over 3 years compared with a health education program.8
Purpose and service
Limited researchVolunteering, mentoring or helping neighbors gives structure and brings you into contact with others. See purpose and meaning.
Steps you can try this week
- Make one contact. Text or call one person you have lost touch with. Keep it simple: "I was thinking of you. How are you?"
- Put something on the calendar. Choose one weekly event, such as a walking group, faith community, class or club. Seeing the same faces each week gives friendships time to grow.
- Say yes once. The next time you are invited somewhere, go for a short time even if you do not feel like it.
- Plan your hard hours. If evenings or Sundays are lonely, plan a call, an outing or a hobby for that time.
- Get your hearing checked if you often miss parts of conversations.
- Watch what you use to cope. If you are drinking more to fill the evenings, see alcohol in midlife.
- Practice kindness toward yourself. The loving-kindness practice can ease feelings of disconnection.
- Use free tools. Our values compass can help you choose activities that fit who you want to be in this new chapter.
After a divorce or separation
Separation is a major loss, even when it was the right choice. Expect waves of grief, anger and relief. It helps to:
- Keep basic routines: regular sleep, meals and movement.
- Limit big decisions in the first months when you can.
- Lean on friends and family, and say clearly what you need.
- Keep conflict away from children, even adult children.
- Get legal and money advice early so that worry does not pile up.
- Try a support group for people going through divorce. See support groups.
If a relationship involved control, threats or violence, your safety comes first. Our unhealthy relationship warning signs checklist can help you think it through.
For partners, family and friends
You may notice a friend, sibling or parent pulling back after a divorce, a death or a move. Reach out on a regular schedule rather than waiting for them to call. Invite them to something specific, such as "Walk with me Saturday at 10?" Listen more than you advise. If they seem hopeless or talk about not wanting to live, ask them directly and help them get support. See helping someone who is isolated.
Adult children can help a parent with an empty nest, too. A short weekly call or video chat means a lot.
Special situations
Men in midlife. If you are a man facing divorce, widowhood or a move, check in with yourself about how connected you feel. See men's health in midlife and depression in men.
Caregivers. Caring for a parent or partner can crowd out friendships. See caregiving in midlife.
Losing a spouse. Grief after a death is different from divorce, but loneliness is common in both. See losing a spouse.
Common questions
Is it normal to feel lost when my kids leave home?
Yes. Many parents feel sad, restless or unsure of their role for a while. These feelings often ease as new routines form. If they last for weeks and you feel hopeless, talk with someone.
How long does it take to feel better after divorce?
It differs for each person. Support, routines and time help most people. If you still feel stuck or very low after several months, counseling can help.
I am married but lonely. Is that possible?
Yes. Loneliness is about the quality of connection, not just having people around. Couples counseling can help partners reconnect, and outside friendships matter too.
Is online contact good enough?
Video calls and messages help, especially with family who live far away. Try to add some in-person contact when you can.
When to get help
Talk with a doctor or counselor if loneliness or sadness lasts more than two weeks, if you have stopped doing things you used to enjoy, or if you are drinking more to cope.
If you have thoughts of suicide, call or text 988, the Suicide & Crisis Lifeline. It is free and open 24 hours a day. If you or someone else is in danger right now, call 911.
