Microplastics are in most of the water we drink, but what does that mean for our health and wellbeing? In this episode of The Happier Life Project, host Gabby Sanderson sits down with Dr. Sherri “Sam” Mason, one of the world’s leading researchers on plastic pollution, to uncover the truth about what’s in our tap and bottled water. 

Together they explore how microplastics affect our bodies and minds, and the small but powerful steps we can take to protect ourselves and the planet. If you’ve been noticing conversations around microplastics and wondering what they mean for your health, or if you’re simply trying to make more informed, empowered choices; this episode will give you a grounded, hopeful place to start.

Dr. Mason’s groundbreaking research not only revealed the widespread presence of microplastics in freshwater systems but also helped shape legislation like the Microbeads-Free Water Act. Her work has been featured across major outlets including the BBC, The Guardian, and The New York Times, sparking global awareness about the hidden costs of plastic pollution. In this episode, she explains how science is catching up to the scale of the problem, and why understanding it is the first step toward change.

Beyond the science, this conversation is about empowerment. You’ll hear how reconnecting and protecting the environment can ease stress, restore a sense of agency, and inspire resilience in the face of overwhelming headlines. Most importantly, you’ll walk away with practical, realistic steps to reduce your exposure and consumption of microplastics; proving that small, consistent actions really do add up to a healthier body, a clearer mind, and a happier life.
