Loneliness: understanding it

Being alone is simply a situation: no one else is around. Many people enjoy solitude. It can be a time to rest, think, create or recharge.

Time alone becomes a problem only when you do not want it, or when it goes on so long that you feel cut off.

Loneliness is a feeling, and it is personal. It depends on what you need. One close friend may be plenty for one person, while another needs a wider circle to feel at home.

It can be about missing a close, trusted person, or about missing a wider sense of belonging, like a group or community.

Social isolation means having too few social ties, like rarely seeing or talking to anyone. It is something that can be counted, not just felt.

Someone can be isolated without feeling lonely, or lonely without being isolated. But the two often go together, and both can affect health.

The NHS describes emotional loneliness as missing a close emotional attachment, like a best friend or a partner. It is the feeling of having nobody to tell your real news to, or nobody to call when something goes wrong.

You can have a busy social life and still feel this. Lots of friendly acquaintances do not always fill the space left by one close, trusted person. It often shows up after a breakup, a death, or when a best friend moves away.

What may help

• Choose one or two people to grow closer to, rather than meeting many new ones
• Share a little more of what is really going on for you
• Spend regular one-to-one time, like a weekly walk or call
• The Ways to reconnect guide has more on deepening connections

The NHS describes social loneliness as not having friends to go out with, or people who share your hobbies and interests. You might have a loving partner or family and still wish you had a group to play, laugh or explore with.

This kind often grows after a move, a new job, retirement, or when friends get busy with new stages of life.

What may help

• Join something that meets regularly, like a class, team, choir or volunteer group
• Invite one person from that group for coffee after a few weeks
• Try a new hobby with a friendly beginner group
• The Ways to reconnect guide has more on making friends as an adult

The NHS describes this as being in a room full of people you know and still feeling alone. It can feel like a deeper sense that nobody truly understands you.

It can come after experiences other people around you have not shared, like a serious illness, a loss, a trauma or a big change in what you believe. It can also come when you feel different from everyone around you.

What may help

• Peer support groups with people who have lived something similar
• Faith, spiritual or values-based communities
• Writing, art or music to put the feeling into words
• Talking it through with a counselor or therapist

The NHS notes that some people feel lonely only at certain times, like Sundays or Christmas. Evenings, weekends, birthdays, anniversaries and holidays can all bring it up, especially when everyone else seems to be busy with people.

Because these times are often predictable, you can plan for them. Having something lined up, even something small, can take the edge off.

Ideas for hard days

• Book a call with someone for that evening or day
• Plan a walk, a film or a favorite meal
• Look for free community events on holidays
• Volunteer on a day that is usually lonely

The NHS says some people feel lonely all the time, which is sometimes called chronic loneliness. If loneliness is very severe or lasts a long time, it may raise the risk of some physical and mental health conditions.

Long-lasting loneliness is not your fault, and it can change. The NHS reminds us that loneliness and difficult feelings can pass.

Chosen solitude might be a quiet walk, reading in a café, a long bath, drawing, gardening or cooking a meal just for you. The NHS suggests filling your time with things you like, such as time outdoors, exercise, reading, podcasts or radio, which can lift your mood.

Good solitude usually leaves you feeling calmer and more like yourself. You come back to people with more to give.

The NHS lists some signs that loneliness may be affecting you, including:

• Getting nervous about, or avoiding, social events
• Changing daily routines, like no longer cooking for yourself, caring about how you look, or getting up early
• Finding it hard to get to sleep or stay asleep

If you notice these, it does not mean something is wrong with you. It is a sign to gently add a little more connection back into your week.

Solitude feels better with a little shape. Instead of drifting into hours of scrolling, plan something you look forward to, like a walk, a hobby, music or a podcast.

Try

• Pick one “just for me” activity each week
• Get outside, even for 10 minutes
• Notice how you feel after: refreshed, or lower?
• Mix quiet time with a bit of being around people, like a library or park

Loneliness depends on what you need, not on a set number of friends or hours. One person may feel content with one close friend and lots of quiet. Another may need a busy social week to feel at home.

Your needs can also change with stress, seasons and life stages. It is okay to check in with yourself and adjust.

When you feel cut off, your mind scans for signs that people do not want you around. Research describes this as heightened vigilance for social threat.

Example: a friend replies “ok” instead of their usual long message. The radar says, “They’re annoyed with me.” In reality, they might just be at work, tired or driving.

Studies found lonely people remember more negative social events than people who are not lonely.

Example: after a party, you replay the one joke that fell flat, and forget the three people who smiled and asked you questions.

Try

• After seeing people, write down one moment that went okay
• Ask yourself, “What would a neutral observer have seen?”
• Keep a short list of kind things people have said to you

When rejection feels likely, it is natural to protect yourself: short replies, turning down invites, leaving early, or not sharing much. Research suggests negative expectations can draw out reactions from others that seem to confirm them.

Other people cannot see your fear. They may think you are not interested, and stop asking. That is how the loop keeps itself going.

Hawkley and Cacioppo report that loneliness is linked to poorer sleep quality, with more tiny awakenings in the night, even when people sleep the same number of hours. In one diary study, lonely feelings predicted feeling less able to function the next day.

Being tired then makes it harder to reach out, which can deepen loneliness. Caring for your sleep is one more way to loosen the loop.

You might feel fairly relaxed once you are with people, but you do not have the closeness or company you want. The main problem is missing opportunities or missing deeper bonds.

Here, the most helpful steps are usually practical: regular activities, invitations and putting time into a few relationships.

NIMH describes social anxiety as a strong fear of being watched or judged. In the moment, people may blush, sweat, tremble, feel their heart race, or find their mind goes blank. They may dread an event for weeks, avoid it, and then pick apart how they did afterwards.

It can look like extreme shyness, but it goes further. It is strong enough to get in the way of work, school or relationships.

Skipping a party brings quick relief, so the brain learns, “Avoiding works.” But each time, the world gets a little smaller and the next invitation feels harder.

Gentle ways in

• Start with lower-pressure settings, like an activity where you do something side by side
• Arrive early, when groups are smaller
• Bring a friend, or ask to just watch the first time
• Plan a kind way to leave if you need to

NIMH calls cognitive behavioral therapy (CBT) the “gold standard” talk therapy for social anxiety. It teaches new ways of thinking and reacting, and helps build social skills. Exposure therapy, a part of CBT, helps people face feared situations step by step. Group CBT and acceptance and commitment therapy (ACT) can also help.

Support groups, in person or online, let people hear honest feedback and learn how others faced similar fears.

WHO found 17–21% of people aged 13–29 feel lonely, with teens highest of all.

You can feel lonely in a crowd, or in a relationship. A few close, real connections often matter more than many shallow ones.

WHO links loneliness to an estimated 871,000 deaths a year worldwide.

Most people feel lonely at some point. It often comes after life changes, not because of who you are.

In Gallup’s 2024 workplace research, working men and working women reported loneliness at the same rate, 20%. The Men’s friendships & connection guide goes deeper.

Loneliness can turn up a “threat radar” that makes people expect rejection. In a review reported by Hawkley and Cacioppo, programs that worked on those thoughts had the biggest effect. More chances to meet people help most when they feel safe.

CDC survey data from 2022 found about 1 in 3 U.S. adults feel lonely. WHO estimates 1 in 6 people worldwide are affected.

A therapist can help you work through loneliness and build strategies for reconnecting with others. Therapy can also help with the worry, low mood or social anxiety that often come with it.

Your clinical provider can also help you find support in your area.

Peer support connects you with people who have been through something similar. Many communities have groups for new parents, carers, grief, newcomers and more.

Libraries, community centers, faith groups and senior centers often know what runs locally.
