If you've ever wondered whether your daily habits are quietly protecting your brain, or quietly working against it, this one's for you. Some of the most powerful things you can do for your memory, your focus, and your long-term brain health aren't found in a prescription. They're in your morning coffee, your nightly sleep, and the way you help your body recover every single day.
I'm joined by returning guest expert Dr. David Perlmutter, a board-certified neurologist and 6-time New York Times bestselling author, to unpack the real science on the choices that shape cognitive function, metabolism, and longevity. We get into why coffee is so much more than caffeine, how deep sleep literally washes waste out of your brain overnight, why tracking your sleep might be one of the smartest health moves you make, and what the research actually says about infrared saunas, cold plunges, and heart rate variability. It's practical, it's evidence-based, and you can start using it today.
What You'll Learn:
• Why coffee is far more than caffeine, and the 90-plus bioactive compounds that may help protect your brain
• The daily coffee sweet spot, and the "caffeine curfew" that guards your deep sleep
• How to choose cleaner coffee: organic, mold-free, water-processed decaf, and why flavored blends are a gamble
• Quality over quantity: why "I slept 8 hours" tells you almost nothing about your brain
• How deep sleep activates the glymphatic system to wash away waste tied to cognitive decline, and the minimum you should aim for
• The everyday habits that quietly sabotage restorative sleep, and why a wearable can help you fix them
• What HRV really measures, why higher means more resilient, and simple ways to raise yours
• Hot & Cold therapy: What the science says about infrared saunas and cold plunges, and why heat and cold may share the same protective pathways
• A crucial caution for breast cancer survivors and anyone at risk for lymphedema before starting heat or cold therapy
• The Mouthwash Habit Your Didn't Realize Is Harming You: The surprising connection between your mouth bacteria, mouthwash, blood pressure, and blood sugar
• Brain-Boosting Movement: Why exercise acts like medicine, turning your muscles into hormone-producing organs that support your brain
...and so much more!

It shocked me that our laundry rooms are often one of the most toxic places in our homes.

For laundry, I found a few brands that are really clean and free of harmful ingredients, but still searched for that fresh scent without the toxic junk.
Found it finally! Here is the link to it (and you can message me to check to see if there are any great offers happening with current savings!
