The Happiness Lab with Dr. Laurie Santos

Struggling to find free time? Feeling constantly busy or burned out? This episode is for you. Dr. Laurie explores the science behind “time famine,” the nagging sense that there’s never enough time in the day.
Writer Tom Hodgkinson, author of How to Be Idle, makes a provocative case that doing nothing (napping, daydreaming, even staring out the window) isn’t laziness, but a powerful path to greater happiness and creativity.
Plus, Harvard professor Ashley Whillans explains why we keep prioritizing money over time and what that trade-off is really costing us.
Experts Mentioned:
Tom Hodgkinson, founder and editor of The Idler and author of How to Be Idle
Ashley Whillans, Harvard Business School professor and author of Time Smart
Cassie Mogilner, UCLA professor of marketing and behavioral decision making
Michael I. Norton, Harvard Business School professor of business administration
John M. Darley and C. Daniel Batson, psychologists behind the Good Samaritan helping study.

Buying something new can trigger a rush of dopamine, leading to a momentary boost in happiness. But the rush is fleeting, and over time, our possessions can end up weighing us down more than they lift us up.
As part of our series on spring cleaning your wellbeing, Dr. Laurie explores why material things so often fail to make us happier, and why experiences are usually a better investment in our long-term wellbeing. Along the way, she talks with psychologist Bruce Hood, researcher Amit Kumar, and writer Cait Flanders, who reflects on the psychological benefits of shifting from a maximalist lifestyle to a minimalist one.
If you’ve ever wondered whether it’s actually worth the time and effort to clean out your closet, this episode offers some answers.

Our surroundings affect our happiness in ways we often don’t notice. The layout of a room, the amount of clutter in our home, and even small changes to lighting can shape our mood, focus, and relationships.
As The Happiness Lab continues its spring cleaning series, Dr. Laurie sits down with University of Virginia Professor Leidy Klotz, author of In a Good Place, to explore the hidden ways our spaces shape our inner lives. Why do certain places make us feel calm, connected, and grounded, while others leave us distracted or drained?
From creating more connection at home to using our surroundings to remember loved ones we’ve lost, these practical ideas will refresh your space and your wellbeing.

Breaking bad habits often feels like a test of willpower. We tell ourselves we’ll stop scrolling, eat better, or exercise more — and then fall right back into the same routines. So why is lasting change so hard?
As part of our spring cleaning series, we’re revisiting a powerful episode from The Happiness Lab archives that reveals a surprising truth about behavior change: it’s not about willpower at all. Dr. Laurie Santos sits down with psychologist Wendy Wood to explore what the science of habits really says about why we get stuck — and how we can finally change.
Along the way, we hear the remarkable story of American soldiers in Vietnam who abruptly overcame heroin addiction after returning home, offering a powerful clue about how habits really work. If you’re looking to break a bad habit or build a better one, this episode shows how small changes to your environment can make lasting change feel almost automatic.
