“While high-intensity interval training (HIIT) might be associated with extreme, all-out efforts, at its core, it's about varying intensity levels, much like "hills and valleys." This adaptability suits many people, including older adults.”

“Chiefly, sleep deprivation triggers the onset of a "loneliness phenotype" by inducing critical changes within the brain that alter behavior and emotions, disturb metabolic processes, and influence the expression of immune-related genes.”

“Detecting SARS-CoV-2 infection pre-symptomatically When the COVID-19 pandemic struck, Dr. Snyder's laboratory began investigating whether heart rate data might be able to inform SARS-CoV-2 infected people before symptoms arose, allowing them to get tested and self-quarantine.”

“Creatine works by building tissue stores, so consistent daily intake matters more than taking it immediately before a specific workout. Dr. Patrick and Dr. Candow also discuss its value during aging, when preserving training quality and muscle becomes increasingly important for function and independence.”

“Dr. Huberman favors training and behavioral cues as the foundation and warns that stacking caffeine, nicotine, music, and other rewards can make effort feel dependent on stimulation.”

“In this member Q&A clip, Dr. Rhonda Patrick shares four practices she uses or finds compelling for healthy aging: sauna, sulforaphane-rich foods or supplements, time-restricted eating, and high-intensity interval training.”

“A pooled analysis of 1,422 participants from 14 intervention trials found that supplemented participants took an average of 1,983 milligrams of EPA plus DHA per day for about 13.6 weeks, while their mean Omega-3 Index rose from 4.9% to 8.1%.”

“In a small study of 10 men, twice-weekly sauna sessions for three months altered sperm production and function, with recovery documented during follow-up after sauna use stopped. Sperm outcomes and circulating testosterone are distinct measures of reproductive function.”

“In this clip from Q&A #68, Dr. Rhonda Patrick compares stearic, palmitic, myristic, and lauric acids and explains why chocolate, cheese, butter, and coconut oil can produce different lipid responses.”

“Activity timing can add another benefit. A meta-analysis of eight crossover trials found that exercise after eating reduced post-meal glucose excursions more than exercise before eating or inactivity, with earlier post-meal activity generally producing a larger effect.”
