What if the chemicals in our food, water, and everyday products were silently influencing our mental health? This week, I’m sitting down with Dr. Aly Cohen, a board-certified rheumatologist, integrative medicine specialist, and environmental health expert, to explore the powerful connection between toxins and mental health. Dr. Cohen’s journey into this space started with a deeply personal loss—the sudden illness of her beloved dog—which set her on a mission to uncover the hidden dangers of environmental chemicals. Now, through her work at The Smart Human podcast and her latest book, Detoxify, she’s empowering people to take control of their health in a way that’s accessible, science-backed, and not fear-based.
How Everyday Toxins Affect Mental Health, Hormones & Gut Health with Dr. Aly Cohen
In this episode, Dr. Cohen breaks down the unseen impact of toxins on our nervous system, hormones, and immune function—factors that play a huge role in anxiety, depression, and overall brain health. We dive into why autoimmune diseases (which disproportionately affect women) are on the rise, how common chemicals known as “obesogens” might actually be blocking weight loss, and why filtering your water could be one of the simplest, yet most impactful, changes for your mental and physical health. Plus, I put her expertise to the test by pulling out some of my own everyday products for an on-the-spot analysis—let’s just say I had a few wake-up calls!
If you’ve ever felt off but couldn’t quite pinpoint why, or if you’re ready to make small, powerful changes to feel better inside and out, this episode is a must-listen. Dr. Cohen’s 21-day detox plan is the perfect way to start reducing your toxic load without overwhelm. Grab her book Detoxify, follow The Smart Human, and let’s take a step toward cleaner living—without the all-or-nothing pressure.
