Episode Description

What if kindness wasn’t soft at all, but one of the most powerful biological forces we have?

In this episode of The Kindness Podcast, Nicole Phillips talks with David R. Hamilton, a former pharmaceutical scientist and one of the world’s leading researchers on the science of kindness.

Dr. Hamilton explains why kindness is literally wired into our genes, how it counteracts stress at a physiological level, and why genuine kindness changes inflammation, immunity, aging, and mental health. They also talk about why “being nice” out of duty does not count, why kindness has real teeth, and how small moments of compassion can ripple out to change lives we will never meet.

This conversation is honest, science-backed, and deeply human.
