Loneliness and depression: How they feed each other
Are you feeling disconnected or isolated? Worried about the link between loneliness and depression? It’s not just you.
While the recent summer season may have made it feel like everyone else is constantly having fun, your social media feed doesn’t tell the whole story. Did you know that:
Loneliness is common:
- Recent data shows nearly 1 in 4 UK adults say they feel lonely ‘often, always, or some of the time.’
Loneliness is most reported among younger people:
- In a 2026 ONS study, adults under the age of 50 were far more likely to report regular feelings of loneliness than people over the age of 70. In fact the age breakdown was:
- 27% in 16-29 year olds
- 28% among 30-49 year olds
- 16% among 70+ year olds
You don’t have to actually be alone to feel lonely, and loneliness among others may sting even more:
- Research shows that socially isolated people do have a higher risk of loneliness
- However, some people can experience a lot of social isolation without feeling lonely; others really struggle with loneliness despite being surrounded by people
- One study involving several thousand people found that feelings of loneliness suffered in the company of others were associated with more negative impacts on mental wellbeing. So it is not only possible to feel lonely around others; it may even be worse than feeling it alone. The quality of our connections matter, not just the quantity.
Because of the social pressure to seem like we’re enjoying ourselves, it can be really hard to admit when we’re feeling isolated, and even harder if we’re worried about falling into a loneliness and depression loop. But you don’t need a diagnosis to seek answers and support. Consultant Psychiatrist Dr Benjamin Janaway says:
“Modern society champions that social connection is normality, but history tells us that much of humanity struggled alone. But even now, in a world of infinite connective possibility, many of us feel even more distant, misunderstood and misplaced. We are not built to be lonely creatures, and for most of us our biology, psychology and spirit tend to suffer alone. We were built to connect, so how do we overcome the barriers? We first realise that pain needs no diagnosis,”
So what is the loneliness and depression loop and what can we do about breaking the cycle of loneliness? Read on.
Is loneliness the same as depression?
No, loneliness and depression are not the same thing – they are separate but often closely related. Loneliness is the distressing void between the connections we want and the connections we actually have. Depression is a diagnosable clinical condition that impacts your mood, cognition, energy and ability to function.
Loneliness and depression are often associated with each other. Researchers have identified loneliness as a potential risk factor for developing depression symptoms. A recent study involving several hundred thousand people concluded that loneliness and social isolation were independently linked with a greater risk of depression. What’s more, people suffering from depression are more likely to be lonely; research has shown the relationship between loneliness and depression can be two-way. As Dr Janaway says:
‘The phenomena of depression captures a range of psychological defenses to multiple, complicated and interacting experiences, often written in the past, enforced in the present and condemning of the future. It is not just sadness, but a whole-body and mind experience of surrender to the world within and without. Loneliness is just one experience alongside many that contribute to a depressive episode, but it is one relatively unique in that to tackle it may not just reduce the risk of depression, but depress the risk further loneliness.’
But while the loneliness and depression loop is common, it is also perfectly possible to experience loneliness without depression and vice versa. So if you’re wondering ‘is my loneliness a symptom of depression’, the answer may be yes or no. You can read more here about the symptoms of depression as well as the symptoms of anxiety.
How does loneliness turn into depression, and back again?
Loneliness can be part of a larger process leading to depression through a mutually reinforcing feedback loop. Loneliness tends to breed negative emotions and threat perception responses in the brain, which over time can lead to depression, and then depression creates physical exhaustion and a loss of social confidence, leading to withdrawal from others which feeds loneliness. And on the loop goes.
How to break the loneliness loop: 5 evidence-based strategies
1. Join a group (or two!)
Whether it’s an arts, music, or activity group, research shows that structured group activities are effective at tackling loneliness because they provide opportunities to meet others and connect. After all, you’ll be there with people who’ve all turned up to meet others too. And what better people to connect with than folk who share your interests? So ask yourself what things you’re interested in and then google some local groups centred around that.
2. Do some acts of kindness
There are a million acts of kindness options: giving up your seat on the bus for someone that needs it more; sending a gift to someone; reaching out to check on a friend or family member that is struggling; doing some volunteering. This ‘prosocial’ behaviour can help reduce unhelpful self-focus and increase positive interactions with others. Indeed research shows that doing prosocial acts can reduce loneliness and boost mood.
3. Try mindfulness training
If you’re suffering from loneliness, mindfulness training can help lower the intensity of negative thoughts and feelings – through non-judgmental, present-moment awareness and acceptance. This then gives you more bandwidth to seek out social interactions and connection. Indeed research has demonstrated that mindfulness training can help reduce loneliness and lead to more social contact.
4. Exercise
If you’re feeling lonely or even depressed, exercise will probably be the last thing you feel like doing. However, it can play an important role in beating loneliness because exercise can help to boost confidence, positive feelings and self-esteem, giving you more internal resources to reach out with.
5. Do some CBT for loneliness
Cognitive Behavioural Therapy (CBT) is proven to be effective in helping people recognise and break out of the negative thought patterns and behaviours associated with chronic loneliness. CBT is a NICE-recommended talking therapy with an enormous evidence base, which is why the NHS considers it a gold-standard first-line treatment for a range of problems. And when it comes to avoiding a loneliness and depression loop, early intervention is key.
But I don’t need therapy, or I don’t have depression, you might think.
Dr Benjamin Janaway says: “Loneliness may be a consequence of many things, but what is often consequential of loneliness is pain. Pain needs no diagnosis, just realisation and action. Research shows CBT is effective at tackling loneliness, helping people to challenge the negative thought cycles and social withdrawal associated with it.”
If you or a loved one is struggling with loneliness or low mood, you can get your life back.
