My mum lives alone. Should I be worried?
Or your dad. The question is the same, and it is one of the most common worries there is: a parent living on their own, a child living somewhere else, and a feeling that something ought to be done without much clarity about what.
The honest answer is that it depends on which of two things is happening. Living alone is a fact about a house. Being lonely is a fact about a person. They overlap less than you would think, and everything you should do depends on telling them apart.
Alone and lonely are not the same thing
Age UK, who have spent decades on this, put it plainly: loneliness is a feeling, about whether the contact someone has is meaningful and meets their needs, while isolation is simply being alone, whether or not that is what they want. Someone can live alone and be perfectly content. Someone else can be surrounded by people and lonely all the same.
A lot of older people who live alone have chosen it, and will defend it. They have their routines, their radio, the neighbour who waves, the Thursday at the church hall. The house being quiet is not a problem to be solved, and treating it as one is a reliable way to be told, politely, to mind your own business.
The worry is the other case: when the quiet stopped being a choice. When the friends who used to phone have died or moved into homes, when the bus route changed, when a hip turned the walk to the shops into a thing to plan rather than a thing to do. The house looks the same from the outside. Inside, the week has hollowed out.
What it does to them, in plain terms
This is where the evidence is uncomfortable, and worth knowing.
Age UK's most recent report found that nine in ten older people who are often lonely are also unhappy or depressed, against four in ten of those who are hardly ever lonely. Roughly one older person in twelve says they are often lonely, and the number grows as the population ages. More than two million people in England over seventy-five live alone, and more than a million older people say they go over a month without speaking to a friend, a neighbour or a family member.
Persistent loneliness is not only miserable. It is associated with poorer sleep, higher blood pressure, faster cognitive decline and a higher risk of dying early, and the research behind that is large and consistent. Nobody is saying your mum will fall ill because her Tuesdays are empty. They are saying that empty Tuesdays, stacked up over years, are a risk to her health in the same category as the things her GP already asks about.
So: alone is fine. Lonely is not fine, and it is not a mood that passes on its own.
Why they will not tell you
If she were lonely, she would say. Wouldn't she?
Almost certainly not. The generation now in their late seventies and eighties was raised on not making a fuss. Loneliness, to many of them, sounds like a complaint, or worse, like a request, and the one thing they are determined not to be is a burden. "I'm fine, love" is not a lie in their book. It is manners.
There is pride in it too. Admitting to loneliness means admitting the life has narrowed, and that the person who used to be the centre of everyone's week is now waiting on someone else's. It is easier to say the telly was good.
And there is the practical fear that if they say it, you will do something: move them, sign them up for things, arrive with a leaflet. So the honest answer stays behind the teeth, and you are left reading the signs instead. We have written about those separately: the practical ones, the social ones, and the ones that only show in the conversation itself.
What actually helps
Not what you would think, mostly.
The big visit is lovely and does very little. A weekend of company followed by three silent weeks is, from her side, a weekend of company followed by three silent weeks. Loneliness is not a tank you fill. It is a rhythm, and what breaks it is regularity, something that comes round. A short call at the same time each day does more for a lonely parent than a long one at random intervals, because the looking forward is half the good of it. Age UK's own analysis found that older people who go a week without speaking to a friend or family member are almost three times as likely to be lonely, which tells you the fix is not intensity. It is frequency.
Beyond family, there is a whole quiet infrastructure for this. Befriending schemes pair an older person with a volunteer who calls or visits every week. Age UK runs them locally and by telephone through The Silver Line, and Re-engage runs Sunday tea parties and call companions for the over-seventy-fives. The Campaign to End Loneliness is a good place to find what exists near her. None of this is charity in the pitying sense. It is, quite often, the best friendship she will make this decade.
Then there are the small structural fixes nobody writes home about: a lift to the thing she used to go to, a standing arrangement with a neighbour, a radio in the kitchen, and a dog, honestly, if she is up to it.
What does not help
Guilt, mainly yours. It produces either paralysis or a grand gesture, and neither of those is a phone call on Wednesday.
Rescue does not help either. The instinct, once you have seen it, is to fix it: move her nearer, fill the diary, arrive with solutions. Most parents experience this as being managed, and dig in. The better move is to add one regular thing, keep it going long enough to become part of her week, and let her tell you it was her idea.
So, should you be worried?
If she lives alone and likes it: no. Keep the contact regular and enjoy her.
If she lives alone and the week has gone quiet, the friends gone, the outings stopped, the same three sentences on every call, then yes, a little, and usefully so. Not because anything dreadful is about to happen, but because loneliness is the kind of thing that gets steadily worse if nobody notices, and steadily better if somebody puts one small regular thing in the way of it.
You noticing is the first of those things.
