New Book Reveals Hidden Dangers in Toothpaste, The Truth About Exercise Myths, and Why Your Monday Anxiety Might Be Changing Your Brain Chemistry

October 20, 2025 — When a licensed psychologist with decades of experience treating Alzheimer's patients and Social Security Disability claimants decides to pull back the curtain on what really affects our health and well-being, you know you're in for some startling revelations.

Dr. Patricia A. Farrell's latest book, Unfiltered Redux: Exploring Uncharted Depths of Mind Where Masks Fall and Wisdom Emerges, drops October 20th, and it's not your typical self-help book. This is the raw, unvarnished truth about the hidden factors shaping our mental and physical health—the things your doctor might not tell you, the research that gets buried, and the everyday exposures that could be silently affecting your brain.

What You'll Discover Inside:

The Toothpaste in Your Cabinet Might Be Poisoning You

Research dating back to 1974 found lead in toothpastes—yet 50 years later, we're still using products that may not be safe. Dr. Farrell reveals which major brands tested positive for neurotoxins and what this means for your children's developing brains.

Your Body Has Multiple Internal Clocks (And They Could Save Your Life)

Forget what you think you know about sleep schedules. Dr. Farrell explains the cutting-edge science showing that when you take medication, eat, or exercise could matter more than what you do—and how understanding your personal biological rhythms could transform your health.

Monday Anxiety Isn't Just in Your Head—It's in Your Hair

Groundbreaking research reveals that people who feel anxious on Mondays have 17% higher stress hormone levels in hair samples collected months later. Dr. Farrell breaks down what this means and provides science-backed strategies to break the cycle.

The 10,000 Steps Myth Finally Debunked

That fitness tracker goal? It came from a 1960s Japanese marketing campaign. Dr. Farrell shares what the actual research says about movement, health, and longevity—and why doing "nothing" might actually be good for your mental health.

Food Insecurity Is Creating Generational Brain Damage

In one of the book's most powerful chapters, Dr. Farrell draws on her own childhood experiences with poverty to expose how malnutrition doesn't just affect one generation—it echoes forward through DNA, affecting children who haven't even been born yet.

A Voice That Won't Be Silenced

Dr. Farrell doesn't mince words. As a former WebMD psychology expert, researcher at Mt. Sinai Medical Center, and consultant across multiple industries, she's seen firsthand how corporate interests, outdated research, and systemic biases shape the health information we receive.

"Too many people suffer because we accept comfortable lies instead of uncomfortable truths," Dr. Farrell says. "This book isn't about scaring people—it's about empowering them with knowledge that could genuinely change their lives."
