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.
