Loneliness can feel hard to shift, and many people wonder whether getting outdoors might help. A study in Barcelona looked at that question by comparing two nature-based approaches. Loneliness scores fell over time in both, but the overall gap between them was not statistically significant, so the study does not show that group outings were better.
A news report dated 23 October 2026 described a study published the same month in The Lancet Regional Health. It enrolled 320 lonely adults in Barcelona, Spain.
One group joined a weekly two-hour outing to parks, gardens and similar green spaces over nine weeks. The comparison group received suggestions for free, accessible outdoor activities they could try on their own.
Since both groups were offered something connected with nature, nobody was left with no activity or support at all. The design can set the two approaches side by side. By itself, though, it cannot show that either caused the drop in loneliness, because no group received nothing.
The report describes checks at three months and at one year, not just a reaction straight after an outing.
Taking both groups together, average loneliness scores dropped by 10.5 per cent at three months. At one year, the reported average fall was close to 17 per cent. Even so, people offered group outings and people given individual suggestions did not differ significantly overall.
Group outings seemed particularly helpful for participants who began with higher loneliness or lower emotional wellbeing. That comes from a subgroup analysis, and the news report does not describe the full method used, so treat it with caution. It should not be taken to mean group activity suits everyone who is struggling.
It is tempting to focus on the improvement over time. The comparison matters just as much. Each group had a nature-related option, and the study found no clear overall edge for the group format. That sits more comfortably with trying out accessible choices than with naming one format as the answer.
The study does not show that a park visit is a cure for loneliness, and it cannot say why scores changed. Without a no-intervention group, the change cannot be put down to the nature component alone. People's circumstances, the passing of time and the attention of being in a study could all play a part.
The news account leaves out the full loneliness scale, confidence intervals, drop-out details and the subgroup method. That makes it hard to judge how precise the average reductions are, or how sturdy the subgroup pattern is. Nor does the report establish that any particular activity will work for an individual.
Outdoor activity will suit some people and not others. Some will welcome a scheduled group outing. Others will prefer a quiet visit at a time of their choosing. Neither preference means a person is making more or less effort.
When looking at an option, you could check on transport, accessibility, cost, timing and how flexible taking part is. These are everyday planning questions, not features that the study showed to explain its results. What matters is finding something that suits you, not living up to some idea of how nature or socialising ought to feel.
If time outdoors appeals, think about whether you would prefer something quiet and solo or with other people, and whether a free, accessible choice exists near you. One small outing can be just that, without turning into a measure of whether you can beat loneliness. The study backs keeping your options open; it does not make outdoor activity a duty.
