Preventative Health Expert: Truth About Biohacking & 2 Non-Negotiable Habits for High Performers

In this episode of Lead with Balance, host Jessie Li sits down with preventative expert Dr. Sinead Sheridan to unpack the truth about optimizing physical and mental performance under chronic stress. If you are navigating high-pressure corporate environments, juggling endless professional and personal demands, and looking for science-backed, easy-to-implement protocols that actually move the needle, this conversation is your ultimate roadmap. From the effective predictor of longevity to the hidden truth about female cardiovascular health and why popular quick-fix trends might be destroying your metabolism, Dr. Sheridan delivers clear, non-negotiable protocols designed for time-poor leaders. In this episode, you will learn: Brain-Boosting Exercise: Physical movement alters brain chemistry, increasing hippocampus size for memory, releasing BDNF for nerve growth, and boosting dopamine, serotonin, and norepinephrine for executive focus. The Hidden Female Heart Crisis: Cardiovascular disease presents differently in women (e.g., fatigue, nausea, jaw/arm pain instead of chest pain) and often hides in microvasculature, leading to frequent emergency room misdiagnoses. Beyond Standard Bloodwork: Standard panels miss critical risk factors; tracking APO B and Lipoprotein(a) provides a true picture of cardiovascular risk. The #1 Longevity Biomarker: Your VO2 Max (aiming for 35) is the single greatest predictor of all-cause mortality and functional capability as you age. Foundations Over Hype: Advanced therapies like NAD+ infusions, hyperbaric oxygen, and red light are ineffective unless your core foundations—sleep, movement, and nutrition—are optimized first.
