In the moment
Call, don't message
Ring one person instead of texting them, five minutes, no agenda
5 min
How to do it
Pick someone you'd normally text and call them instead. It doesn't need a reason. Five minutes of an actual voice does something a thread of messages doesn't.
What the evidence says
The research on loneliness is specific about what works: contact alone, of the kind a text thread gives you, showed limited effect in the largest recent review of trials, while programs with a real social or group part did better. A call is a small, doable step in that direction.
