If you’ve ever felt like making friends as an adult feels impossible, or you’ve looked around and thought, "Where did all my friends go?" – you are not alone. Or maybe you have friends, and you want deeper connections, but you don’t know how to create it without forcing it. Friendship is hard right now. Which is why today, Mel is sitting down with Harvard-trained social scientist and bestselling author, Kasley Killam, who has spent the last 15 years researching friendship, connection, and loneliness.

WHAT IT’S REALLY ABOUT

Why adult loneliness grows and research-backed steps to rebuild friendships

  1. They frame “social health” as a core pillar of overall wellbeing—alongside mental and physical health—with measurable effects on stress, disease risk, and longevity.
  2. They argue modern life (work hours, commuting, moving more, living alone, phones/social media) systematically reduces in-person time with friends and makes isolation feel “normal.”
  3. They distinguish legitimate boundaries (“needs”) from common avoidance patterns (“excuses”) like fatigue, “me time,” or insecurity, emphasizing that connection often restores energy rather than drains it.
  4. They offer concrete tools to rebuild connection: prioritize micro-moments, schedule recurring touchpoints, pursue shared-activity communities, and use the 5-3-1 social health formula.
  5. They normalize loneliness and social anxiety, citing studies showing people underestimate how much others like them and how much outreach is appreciated—making small bids for connection highly effective.

IDEAS WORTH REMEMBERING

5 ideas

Treat social connection as health maintenance, not a luxury.

They argue loneliness can raise health risks comparable to major lifestyle factors, so friendships aren’t optional “nice-to-haves”—they’re preventative care for stress, mental health, and physical resilience.

Loneliness is a signal, not a personal failure.

Killam reframes loneliness as your brain’s cue that you need connection (similar neural activation to hunger), reducing shame and turning it into actionable information.

Most “I’m too tired/busy” moments are avoidance that worsens burnout.

The episode highlights the stress-buffering hypothesis: supportive contact can lower stress physiology, meaning the thing you’re skipping is often the antidote to how you feel.

Use the 5-3-1 formula to make connection concrete and trackable.

Aim to interact with 5 different people each week (diverse ties), maintain at least 3 close relationships, and spend 1 hour/day connecting cumulatively (preferably voice or in-person, not just texts).

Replace scrolling with “connection first” micro-moments.

When you have spare minutes (between meetings, in line, commuting), text or call someone instead of defaulting to social media; even 10-minute calls can reduce loneliness.

WORDS WORTH SAVING

5 quotes

If you are feeling lonely right now, the first thing I wanna say is that it is nothing to be ashamed of. It does not mean that you are not lovable or likable.

— Kasley Killam

Loneliness registers as a cue in our brain. It's literally a signal telling you, "Hey, there's something you need that you're not getting."

— Kasley Killam

I really worry that people will protect their peace so much that they have no one.

— Kasley Killam

What are we burned out and working so hard for if not to then be able to spend time with the people we love?

— Kasley Killam

Taking care of your social health is a way to change your life and change the world.
