The Human Upgrade: Biohacking for Longevity & Performance
Raw Garlic "Ultimate Biohack" Trend Faces Scientific Scrutiny
Raw garlic has gone viral as a morning ritual, with fans crushing a clove, mixing it with honey, and crediting it with everything from lower cholesterol and better insulin sensitivity to cleared acne, eliminated brain fog, and colds cured within 24 hours. The biochemistry behind the trend is real: garlic contains no allicin until it's crushed or chopped, which mixes an enzyme with a sulfur compound to form the active compound, and letting it sit for ten to fifteen minutes before cooking preserves more of that activity. Host Dave Asprey separates what the human data actually supports, modest blood pressure and cholesterol effects, real antimicrobial properties, and a genuine bleeding-risk caution for anyone on blood thinners, from the unproven parasite-cleanse and brain fog claims driving the trend online, drawing on his own EEG tracking to challenge the cognitive benefit narrative directly.

HEPA Air Filtration Linked To Measurable Brain Function Improvements In One Month
A new study found that older adults using true HEPA filtration to reduce indoor fine particulate matter saw small but measurable cognitive improvements after just one month, adding to a growing body of evidence connecting air pollution exposure to neuroinflammation and long-term cognitive decline. Host Dave Asprey breaks down why clean air belongs in the biohacking conversation alongside supplements and training protocols, and why the World Health Organization's decision to list air pollution as a modifiable dementia risk factor is a bigger deal than it sounds.

Egg Yolk-Derived Peptides Show Neuroprotective Effects Against Oxidative Stress
New research on phosphopeptides isolated from egg yolk phosvitin found that the compounds reduced reactive oxygen species, improved antioxidant defense markers, and increased neuron survival in cells exposed to oxidative stress in the lab. Host Dave Asprey connects this early but promising finding to his long-standing case for the whole egg, yolk included, as one of the most nutrient-dense foods available, and flags what would need to happen next for this to translate into a usable protocol.

Heat Stroke Survivors Face Elevated Cardiovascular Risk Years Later, Research Shows
A closer look at heat stroke recovery reveals it's rarely a one-day event. Survivors of classic heat stroke had three and a half times the rate of ischemic heart disease twelve years later compared to matched controls, along with elevated long-term risk of kidney disease and lingering heat intolerance, fatigue, and dizziness. Host Dave Asprey draws the line between the controlled heat stress he uses deliberately in sauna and hyperthermic conditioning and the uncontrolled, uncooled heat exposure that leaves this kind of lasting cardiovascular damage, and what that distinction means for how to think about any stressor.

Long-Term Melatonin Use Linked To Nearly Double Heart Failure Risk In Large Cohort Study
A cohort study of over 130,000 adults with chronic insomnia found that those who used melatonin for a year or more had nearly double the rate of heart failure and all-cause mortality compared to non-users, along with a three and a half times higher rate of heart failure hospitalization. Host Dave Asprey walks through why this is observational data, not proof of causation, and why he's stayed a low-dose, occasional melatonin user for years rather than a nightly one, plus what the real underlying driver of chronic insomnia might be for listeners still relying on it every night.
