“A smaller comparative study found improved hair density, shaft size, and anagen-follicle proportion with 2 percent ketoconazole shampoo, while its authors called for larger controlled studies. These results support individualized combinations rather than one universal protocol.”

“Dr. Mattson contends that unstressed cells become complacent, making them more vulnerable to the stressors that cause disease, including oxidative stress and inflammation. In modern times, fasting and exercise are behaviors that mildly stress cells.”

“Contrary to the traditional view of lactate as a metabolic waste product, it is now recognized for its critical role in brain health. Elevated lactate levels after vigorous exercise are linked to improved executive function, hinting at its potential protective benefits against neurodegenerative diseases.”

“In a crossover experiment with 12 healthy adults, six 40-second high-intensity cycling intervals increased circulating BDNF four to five times more than 90 minutes of light cycling. The BDNF response also tracked with the rise in circulating lactate.”

“Patients assigned to supervised exercise during neoadjuvant chemoradiation, followed by continued activity before surgery, were more likely to achieve a complete or near-complete pathological response than those receiving usual care.”

“The physical activity guidelines and estimates on how much activity we need are heavily based on self-reported activity, which is useful but imperfect: people remember going for a run, but they forget the short, intense bursts in daily life like sprinting up stairs, chasing kids, and running to catch a bus.”

“Genetics plays an important role in longevity, but there is also a strong lifestyle component. Dr. Snyder's research, using deep molecular measurements, indicates that when you exercise, a profound molecular change occurs — particularly when it comes to immune molecules.”

“In this excerpt from Dr. Rhonda Patrick's A4M LongevityFest 2023 keynote, she argues that vigorous exercise is one of the most powerful tools for healthy aging because it can raise cardiorespiratory fitness.”

“In 25,241 adults who reported no structured exercise, a median of three one- or two-minute vigorous lifestyle bouts per day was associated with 38% to 40% lower all-cause and cancer mortality and 48% to 49% lower cardiovascular mortality.”

“Controlled human studies support acute brain-related responses to high-intensity exercise. Six short all-out cycling intervals improved selected learning and executive measures while increasing circulating BDNF, IGF-1, and VEGF; lactate tracked several of these changes.”
