Poor sleep tracks with inflammation, chronic disease, and mortality risk. The signal is meaningful, but the strongest outcome evidence is observational—not proof that a better sleep score adds years to life.

Promising signal
Creatine is one of the rare supplements where the baseline evidence is not flimsy. That makes the overclaim risk more interesting: strong sports-nutrition evidence is now being stretched into cognition, depression, aging, women’s health, sleep deprivation, and neuroprotection.

Promising signal
Sauna has a stronger long-term cardiovascular and mortality signal than most cold-plunge claims. Cold exposure has acute physiology, mood appeal, and recovery tradeoffs. Contrast therapy adds ritual, but not automatic evidence.

Lifespan is how long you live; healthspan is how much of that time you can move, think, recover, and participate in life well.
News cycle
FDA's July advisory meeting covers BPC-157, Semax, Epitalon-related substances, MOTS-c, TB-500, KPV, DSIP/emideltide, and other peptide-related bulk substances popular in longevity circles.
Why now
The FDA calendar puts several longevity-clinic peptide favorites into a formal public regulatory review window.
FDA advisers will review whether several popular peptides should be allowed for certain pharmacy compounding uses, while FDA materials flag limited human evidence and potential safety or quality concerns.
Why now
The peptide gray market just got a real FDA spotlight: BPC-157, TB-500, MOTS-c, Semax, and Epitalon are heading into a public review.
Secondary coverage revived the idea that accelerated biological aging could help explain rising early-onset cancer risk, but the primary paper needs review before publishing.
Why now
The primary journal record and institutional explanation support a bounded risk-marker brief while media pickup shows why the claim needs careful framing.
