We keep thinking loneliness needs a big fix. A 2021 trial tested something smaller.
Trained volunteers phoned 240 isolated adults, most of them 65 or older, for four weeks. Another group got no calls.
At four weeks, the group that got the calls reported less loneliness, less depression and less anxiety. Physical health did not change, and the study did not test family stories.
Being listened to, by a voice, is not small. It is just a phone call.
The full breakdown is in the comments.
