Andrew Huberman, Stanford neurobiology and ophthalmology professor and popular science communicator. He explores pandemic-driven self-care, the rise and risks of peptides and GLP-1s, wearable sleep and circadian tracking, noninvasive tools to modulate focus and physiology, and how AI could personalize health learning.

Episode notes
Calm Anxiety With Long Exhale Breathing
- Use simple mechanistic tools to control acute anxiety, for example long-exhale breathing to slow heart rate via the vagus nerve.
- Huberman recommends long exhale breathing because respiratory sinus arrhythmia links exhalation to vagal-induced heart rate reduction.
GLPs Could Reshape Population Obesity
- GLP drugs (like retatrutide) can enable substantial weight loss and may shift obesity norms by making healthy weight achievable without heavy exercise.
- Retatrutide showed up to ~33% body weight loss and appears to spare muscle more than earlier GLPs.
Source Peptides From Verified Suppliers
- Prefer reputable sourcing for peptides: compounding pharmacies or gray-market suppliers with test data over opaque black-market vendors.
- Huberman warns about contamination risks (e.g., lipopolysaccharide) and recommends validated purity certificates.
