The hidden cost of going it alone: what loneliness does to men’s health

Loneliness is not just an unpleasant feeling. Persistent social disconnection can affect physical health, mental health and how well we function.

You wouldn't ignore chest pain for six months and say:

“I'll probably be alright.”

You wouldn't break your ankle and decide:

“Other people have worse problems.”

Yet when something is happening socially or emotionally, men can be remarkably good at doing exactly that.

We carry on.

Work.

Sort things.

Get through the week.

Tell ourselves we don't need anybody.

And because loneliness doesn't normally arrive with a flashing warning light, it's easy to treat it as something vaguely unpleasant rather than something worth taking seriously.

But social connection isn't simply a nice extra.

The World Health Organization now describes loneliness and social isolation as significant public-health issues, with links to physical health, mental health and premature death.

That doesn't mean:

“Loneliness gives you heart disease.”

Human health is far more complicated than that.

But it does mean that persistent disconnection deserves more respect than:

“I should probably get out more.”

First, loneliness and social isolation are not quite the same thing

These terms often get thrown together.

They're related.

But they're different.

Social isolation is more objective.

It refers to having relatively little social contact or few social relationships.

Loneliness is subjective.

It is the feeling that the connection you have does not match the connection you want or need.

That distinction matters.

A man can live alone and feel perfectly connected.

He sees mates.

Has hobbies.

Speaks to family.

Feels part of something.

Another man can live with a partner and children, spend forty hours a week around colleagues, and still feel lonely.

The WHO describes social connection as the ways people relate to and interact with one another, and distinguishes both loneliness and social isolation as forms of social disconnection that can affect health.

So this isn't about counting how many people are around you.

It's about whether you actually feel connected to any of them.

Why this matters to men

I don't want to pretend loneliness is exclusively a male problem.

It isn't.

Current England data does not show men consistently reporting more loneliness than women.

But that doesn't make male loneliness unimportant.

The issue for some men is recognising it.

A man may never say:

“I'm lonely.”

He may say:

“I've become a bit of a miserable bastard lately.”

Or:

“I don't really see anyone.”

Or:

“I just work and come home.”

Or:

“I can't be bothered doing anything.”

Or nothing at all.

If the language stops us seeing the pattern, we miss opportunities to do something about it.

The health bit: let's avoid the ridiculous headlines

You've probably seen claims such as:

“Loneliness is equivalent to smoking 15 cigarettes a day.”

It's catchy.

It's also the sort of claim that gets repeated so often that nobody stops to ask what it actually means.

I don't think we need to exaggerate the evidence.

The evidence is concerning enough.

The WHO's 2025 Commission on Social Connection concluded that loneliness and social isolation are associated with:

• cardiovascular disease;

• stroke;

• type 2 diabetes;

• cognitive decline;

• depression and anxiety;

• premature mortality.

The Commission estimated that loneliness contributes to around 871,000 deaths globally each year, although these are population-level estimates based on epidemiological evidence, not a claim that loneliness can be identified as the sole cause of an individual death.

That's the distinction I think responsible health information should make.

Association isn't the same as saying:

“You were lonely, therefore you became ill.”

Health is affected by genetics, behaviour, environment, income, sleep, physical activity, access to healthcare, stress and dozens of other things.

Social connection is one part of that picture.

But it is a part worth taking seriously.

🧠 What’s actually going on?

One way social disconnection may affect health is through stress.

Human beings are social animals.

For most of our evolutionary history, being part of a group wasn't just pleasant.

It improved your chances of survival.

A brain that notices social rejection, exclusion or lack of support therefore isn't behaving irrationally.

It is responding to something humans have historically needed.

Persistent loneliness can be associated with:

• greater stress;

• poorer sleep;

• changes in health behaviour;

• reduced motivation;

• less physical activity;

• increased anxiety;

• lower mood.

Then those things can interact.

You feel low.

So you go out less.

You go out less.

So you feel more isolated.

You sleep badly.

So you have less energy.

You have less energy.

So you're less likely to do something social.

Before long, loneliness isn't one isolated problem.

It's part of a loop.

The MoMENtum insight: The Isolation Loop™

I think the pattern often looks like this:

Feel disconnected

↓

Withdraw

↓

Do less

↓

Fewer opportunities for connection

↓

Mood and energy fall

↓

Everything feels like more effort

↓

Withdraw further

That's The Isolation Loop™.

And there's an important point here:

Loneliness can make you do exactly the things that keep you lonely.

You don't feel sociable, so you stay home.

You stay home, so there is no chance of a decent conversation.

Nothing changes, so staying home starts feeling increasingly normal.

That doesn't mean you're lazy.

It means the easiest short-term choice can reinforce the longer-term problem.

Loneliness and mental health

The link here is particularly important.

The WHO reports that people experiencing loneliness have a substantially increased risk of depression, and its 2025 Commission also links social disconnection with anxiety and thoughts of self-harm or suicide.

Again, this doesn't mean every lonely man becomes depressed.

Nor does depression always begin with loneliness.

The relationship can go both ways.

Low mood can make people withdraw.

Withdrawal can increase loneliness.

Anxiety can stop someone joining things.

Isolation can make anxiety worse.

That's why I don't particularly care which one officially came first if they're now feeding each other.

We need to interrupt the cycle somewhere.

Alan’s perspective

I think we've made a mistake when talking about men's wellbeing.

We sometimes make everything about mental illness.

A man says:

“I haven't got anyone to do anything with.”

And we immediately want to turn it into a mental-health intervention.

Sometimes the answer is far less complicated.

He needs mates.

He needs somewhere to go.

He needs a reason to leave the house that isn't:

work,

Tesco,

or taking the dog out.

That doesn't trivialise mental health.

Quite the opposite.

It recognises that not every wellbeing problem needs to become therapy before we're allowed to address it.

MoMENtum was built around that idea.

We're not a counselling service.

We're not trying to get men to disclose things.

We're trying to create something that adulthood removes surprisingly efficiently:

regular human contact that doesn't require a major reason.

Sometimes having somewhere to go on Sunday morning is useful in itself.

Why men can ignore the early signs

Loneliness rarely announces itself dramatically.

The social circle gets smaller.

Then smaller again.

You stop being invited because you've said no a few times.

Or you stop asking because everyone seems busy.

Perhaps work becomes the main source of conversation.

Then retirement comes.

Redundancy.

Working from home.

Divorce.

Children leaving home.

Suddenly the social scaffolding that was holding everything up changes.

And the man discovers he had fewer independent connections than he realised.

This can be particularly difficult because admitting:

“I don't have many friends anymore.”

can feel embarrassing.

As if friendship was something you were supposed to have sorted out years ago.

It wasn't.

Friendship is maintained.

And anything requiring maintenance can deteriorate when it is neglected.

Retirement can expose the problem

Think about a man who's worked for forty years.

Every weekday he has:

people around him;

structure;

banter;

responsibility;

somewhere to go;

a reason to get up.

Then one Friday everybody gives him a card.

On Monday morning?

Nothing.

He may have looked forward to retirement for years.

And still be surprised how much of his connection was actually coming from work.

It doesn't mean retirement is bad.

It means we need to think beyond money when planning for it.

What replaces the people?

The routine?

The sense of belonging?

Those questions matter.

Working from home has changed the social equation too

Remote working can be brilliant.

No commute.

No office politics at the photocopier.

No pretending to care about somebody else's journey on the A38.

But it can also quietly remove hundreds of tiny interactions.

Morning chat.

Coffee.

Lunch.

A joke.

Walking past somebody's desk.

None of those conversations seems significant.

Collectively, they create social contact.

If you work from home and your partner goes out to work, you can sometimes reach 6pm having spoken to almost nobody face-to-face.

Do that repeatedly and it changes the texture of your week.

That's one reason I think people need intentional connection now in ways previous working patterns sometimes provided automatically.

Separation and divorce

This can hit hard.

A relationship ends.

And alongside the relationship itself, a man can lose:

shared friends;

couples' social events;

family routines;

weekend structure;

even the person who previously organised most social contact.

Suddenly he has free evenings.

But no plan for them.

The obvious response can become:

work more.

Drink more.

Scroll more.

Stay home.

None of those necessarily creates the thing that's actually missing.

Connection.

What about heart health?

This needs careful wording.

The WHO's 2025 report identifies social isolation and loneliness as factors associated with cardiovascular disease and stroke at population level.

Scientists are still working through the precise mechanisms.

Possible pathways include:

• prolonged physiological stress;

• inflammation;

• blood-pressure effects;

• disrupted sleep;

• health behaviours such as inactivity;

• reduced practical or emotional support.

But don't read this and panic that a quiet weekend is damaging your heart.

That's not what the evidence says.

We're talking about patterns of persistent social disconnection across populations.

The useful takeaway is much simpler:

Your social life is part of your health, not completely separate from it.

Social connection can support healthier behaviour

Think about exercise.

It's considerably easier to cancel a walk you've planned with yourself than one where another person is waiting.

Same with:

cycling,

football,

gym,

walking groups,

even simply leaving the house.

Social connection can give behaviour structure.

That's one of the reasons activity-based groups make sense to me.

You're not just asking somebody to:

“be less lonely.”

You're giving them:

a time,

a place,

something to do,

and other people who are turning up too.

That's much easier to act on.

🔎 What I see at MoMENtum

Men don't necessarily arrive saying:

“I'm here because I'm concerned about the long-term health consequences of social isolation.”

Thank God.

They say:

“I thought I'd get out of the house.”

Or:

“Someone mentioned this group.”

Or:

“I don't know many people in Plymouth.”

Good.

That's enough.

You don't need an emotional diagnosis before you're allowed more social connection.

Sometimes the most useful thing about a group isn't what anyone says.

It's that somebody notices if you haven't been for a while.

That's belonging in a very simple form.

Why “just talk to someone” isn't enough

I see this advice everywhere.

Feeling lonely?

“Reach out.”

Great.

To whom?

That's exactly the problem.

If somebody already has a strong support network, reaching out is realistic.

If they haven't spoken properly to a mate for two years, it may feel enormous.

We need more practical advice.

Not:

“Connect more.”

But:

“Go somewhere regularly enough to become known.”

That's actionable.

The Connection Prescription™

Not a medical prescription.

Just a useful framework.

If social connection matters to health, I think rebuilding it needs four ingredients.

Regularity

One event won't transform your life.

Familiarity

You need to see some of the same people repeatedly.

Activity

Something to do reduces pressure.

Reciprocity

Eventually connection needs to go both ways.

That is The Connection Prescription™.

It's not complicated.

It's just not instant.

⚠ The bit nobody tells you: health benefits aren't immediate rewards

You can't go to one coffee morning and announce:

“Excellent. Cardiovascular risk reduced.”

That's obviously nonsense.

The health evidence concerns longer-term patterns of social connection and isolation.

The immediate benefits are usually much more ordinary.

You got out.

Had a laugh.

Walked.

Met somebody.

Your day felt different.

That's enough.

Healthy patterns are usually built from ordinary repeated behaviour.

When loneliness needs more than a social group

This is important.

MoMENtum is social connection.

It isn't therapy.

If loneliness is happening alongside:

• persistent depression;

• severe anxiety;

• substance dependence;

• thoughts of suicide or self-harm;

• significant mental-health deterioration;

then a social group may be useful as part of someone's life, but it isn't a substitute for professional help.

In England, urgent mental-health support can be accessed through NHS 111 by selecting the mental-health option. If there's immediate danger, call 999 or attend A&E.

Social connection matters.

So does knowing when something requires more.

🌱 One small step this week

Don't decide to “be healthier socially”.

That's meaningless.

Choose one measurable thing.

Perhaps:

Message one friend.

Walk with someone.

Attend one recurring group.

Have coffee somewhere other than home.

Volunteer for something.

Come to one MoMENtum event.

Then notice how you feel afterwards.

Not whether you've solved loneliness.

Whether the day was better because another person was part of it.

That's useful information.

Frequently asked questions

Can loneliness affect physical health?

Persistent loneliness and social isolation are associated with poorer physical-health outcomes, including cardiovascular disease, stroke and premature mortality. These are population-level associations and do not mean loneliness directly causes every individual illness.

Can loneliness cause depression?

Loneliness and depression are strongly related, but the relationship can run in both directions and not everyone who is lonely becomes depressed. The WHO reports that lonely people have a higher risk of depression.

Is loneliness as bad as smoking?

Comparisons between loneliness and a specific number of cigarettes are simplifications of population-risk research and can be misleading. It is more accurate to say persistent social disconnection is associated with increased risk of poor health and premature mortality.

Is social isolation the same as loneliness?

No. Social isolation describes limited social contact more objectively; loneliness describes the subjective feeling of insufficient or unsatisfying connection.

Are lonely men more likely to die young?

Research links social isolation and loneliness with premature mortality across populations, including men and women. Individual risk depends on many interacting health, behavioural and social factors.

Does having a partner protect against loneliness?

It can provide valuable connection, but being partnered does not guarantee somebody will not feel lonely or lack friendships and community.

Can joining a group improve health?

Regular social connection can support wellbeing and healthier behaviours, and the WHO recommends community strategies, groups, volunteering and everyday relationship-building among approaches to strengthen social connection.

How much social contact do I need?

There is no universally correct number of friends or social hours. Quality, reliability, belonging and whether your relationships meet your needs matter as well as frequency.

Can exercise help loneliness?

Activity can help wellbeing generally, but activity with other people has the additional advantage of creating opportunities for repeated social contact.

Why does loneliness make me tired?

Loneliness can coexist with poor sleep, stress, depression and lower activity, all of which may affect energy. Persistent fatigue should not automatically be assumed to be caused by loneliness and may warrant medical assessment.

What if I don't like talking about feelings?

You don't need to begin there. Activity-based groups can create social contact through walking, coffee, meals or shared interests without requiring personal disclosure.

Is MoMENtum a mental-health service?

No. MoMENtum is a men's social connection group. It can support friendship, routine and belonging but isn't a replacement for counselling, medical care or specialist mental-health services where these are needed.

The MoMENtum question

Here's the question I'd ask:

“If you thought about social connection as part of your health, would you treat it differently?”

Most of us understand exercise.

Sleep.

Food.

Blood pressure.

We know those things matter.

Friendship?

That gets whatever time is left.

Then the time disappears.

And the friendships go with it.

Perhaps we should stop thinking of connection as something slightly indulgent that men fit around the serious parts of life.

It is one of the serious parts.

You don't need fifty friends.

You don't need a huge social calendar.

You don't need to discuss your deepest emotions every week.

But having people in your life who know you, notice you and expect to see you matters.

The evidence increasingly says it matters to health.

My experience says it matters to how life feels as well.

And you don't need to wait until you're desperately lonely to do something about it.

Start earlier.

Go somewhere.

Become a familiar face.

Have a coffee.

Walk.

Laugh.

Come back next time.

It sounds almost too ordinary to be important.

Maybe that's why we've underestimated it.

Looking after yourself isn't only about what you eat, how much you exercise or whether you get enough sleep. It also includes who you share your life with.
