Feeling lonely can change the way your brain operates.
Kasley Killam, Harvard-trained friendship expert and researcher on social connection, shares that when you’re lonely for a long time, your brain shifts into protection mode.
Kasley shares research that found that the brain of someone who’s been isolated all day looks similar to the brain of someone who hasn’t eaten all day.
Your brain treats loneliness like hunger… a biological cue saying, “You’re missing something essential.”
It makes you more guarded. You notice negative cues more than positive ones.
And without meaning to, you can pull back from the connection you’re actually looking for.
This conversation on The Mel Robbins Podcast with Kasley reframes loneliness as normal, useful information from your body, and a starting point for rebuilding your social health.
