“For example, robust evidence indicates that exercise, sauna use, cold exposure, eating plenty of polyphenol-rich fruits and vegetables, and many other lifestyle factors slow aging. But recent research has revealed some promising technologies that may slow, or even reverse, some markers of aging.”

“Ultraviolet (UV) light exposure – from the sun or tanning beds – causes premature skin aging, a process called photoaging. But a new study in mice found that supplemental collagen, which is rich in the glycine-proline dipeptide, protects against the damaging effects of UV light exposure.”

“Without these nutrients, the body has to compensate for the shortages – a concept known as "triaging." Long-term compensation contributes to aging. Watch this clip in which Dr. Bruce Ames explains this phenomenon in what he calls his triage theory.”

“The arrival of a new year is a great opportunity to make health-focused resolutions – promises to ourselves that we're going to live better, healthier, and (hopefully) longer. We all age at different rates, however, so our chronological age – the number of years we've lived – often differs from our biological age.”

“These findings suggest a mismatch between one's biological preferences and sleep schedule can harm mental well-being. The investigators posited that people should aim to sleep before 1 a.m. for optimal mental health, even if their natural chronotype favors later sleep.”

“Older adults can have anabolic resistance and may need more protein per meal to reach a leucine threshold; Dr. Schoenfeld discusses roughly 2–3 grams of leucine as a flexible estimate, not a hard cutoff or a reason everyone needs isolated leucine.”

“Scientists have speculated that regular heat exposure, such as that experienced in a sauna, might help aging muscles adapt in ways that preserve strength and mass. A recent study found that older adults who engaged in infrared sauna sessions regularly experienced a 33% increase in the number of small blood vessels surrounding their muscle fibers.”

“Partial reprogramming attempts to restore more youthful cellular features without pushing a cell fully back into a stem-like state. In animal studies, cyclic expression of reprogramming factors has improved selected aging-associated features and regenerative functions.”

“Children of the women who took the drug during pregnancy were 13 percent more likely to have ADHD-like behaviors at the age of 7 years; 29 percent more likely to take ADHD medications; and 37 percent more likely to be diagnosed with a hyperkinetic disorder at birth.”
