What Screen Time Is Really Doing to Your Body with Manoush Zomorodi

We hear a lot about how screens affect our mental health, but time spent on computers and smartphones is having just as much of an impact on our physical health — from brain fog and weakened core muscles to changes in our posture, our sleep, and even the shape of our eyes. As part of our series on spring cleaning your wellbeing, Dr. Laurie sits down with journalist and podcast host Manoush Zomorodi, author of Body Electric, to explore how modern tech habits are affecting us physically, and what steps we can take to protect our health in a world where screens aren’t going away anytime soon.

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.

Forgiveness might sound simple, but it's hard to let go of the anger that comes with being deeply hurt. Grudges, bitterness, and frustration with life’s unfairness can quietly build up over time and take a real toll on our mental and physical health. As The Happiness Lab kicks off a new season on spring cleaning your wellbeing, Dr. Laurie sits down with psychologist Dr. Fred Luskin, director of the Stanford University Forgiveness Project, to explore what research says about forgiveness. Why is letting go of resentment so much harder than it sounds? And what does it really mean to forgive someone? Plus, we revisit a powerful story from the archives that shows what forgiveness can look like in the face of profound loss and why it might be the most radical act of self-care we can take.

Why is social media so hard to quit? We waste hours scrolling, feel worse when we log off, and still find ourselves going back for more. Dr. Laurie sits down with Dr. Cass Sunstein, co-author of (00:00:57) Nudge, to explore a new concept from the 2026 World Happiness Report: the “product trap.” Together, they unpack why we keep returning to platforms that make us unhappy — and what it might take to finally break free.

Dr. Laurie sits down with her to unpack new findings from the 2026 World Happiness Report on how social media use affects teen wellbeing around the world.

Work doesn’t end when the workday does. Even after we close our laptops, our minds keep replaying awkward meetings, looming deadlines, and unfinished to-do lists. Over time, that “always on” mentality can quietly hijack our relationships, our health, and our happiness.
