In this episode, Christa Elza and Sheree Beaumont explore practical, science-backed ways to protect and optimize cognitive health, long before symptoms of decline appear. From sleep and hormones to exercise, nutrition, adaptogens, and supplements, this conversation empowers you with tools to safeguard memory, focus, and resilience.    Whether you’re in your twenties or forties, the choices you make today set the stage for sharper thinking, stronger mental health, and longevity in the decades to come.   [00:01 – 07:59] The Power of Sleep & Impact of Alcohol Sleep is the most underrated “nootropic,” more powerful than supplements Deep sleep clears toxins like beta amyloid linked to Alzheimer’s REM sleep drives creativity, problem-solving, and memory Alcohol disrupts restorative sleep, causes brain inflammation, and shrinks the hippocampus [08:00 – 13:39] Hormones & Cognitive Protection Estrogen acts as a neurosteroid, protecting synapses and enhancing neurotransmitter activityProgesterone supports GABA receptors, promoting calmness and improved sleep Testosterone aids memory, drive, and motivation in both men and women Cortisol, when chronically high, damages neurons—stress resilience is crucial   [13:40 – 18:08] Exercise, Muscle Mass & Brain Health Exercise is a natural nootropic that improves clarity and mood Strength training enhances insulin sensitivity and lowers dementia risk Aerobic activity increases BDNF, supporting neuroplasticity and recovery Muscle mass acts as a glucose buffer, protecting long-term brain health [18:09 – 27:33] Mushrooms, Adaptogens & Nootropics Lion’s Mane stimulates nerve growth factor for new neural connections Cordyceps enhances stamina and focus, while reishi and chaga help reduce inflammation Nootropics like L-theanine, ginkgo, and NAD support calm focus and energy Adaptogens (ashwagandha, rhodiola, holy basil) regulate cortisol and enhance resilience [27:34 – 34:30] Nutrition, Supplements & Daily Practices Ketogenic diets can aid ADHD, seizures, and neurodegeneration, but the Mediterranean diet is more sustainable High-quality fats (omega-3s, MCT oil) are essential for cognitive health Creatine supports ATP production and may protect against neurodegeneration. Foundational habits, such as whole foods, strength training, and hormone optimization, reate lasting brain protection   Key Quotes: “You have to be intentional about your health and don’t forget your brain, your future self will absolutely thank you.” - Christa Elza   “Creatine isn’t just for the gym bros, it’s one of the most researched supplements for brain health and protecting against neurodegeneration.” - Sheree Beamont   Connect with Sheree!  Instagram: https://www.instagram.com/shereehannahwellness/ LinkedIn: https://www.linkedin.com/in/sheree-hannah/   Connect with Christa!
