A long-running Chinese cohort suggests nighttime sleep and physical activity don't just add up for the aging brain — they multiply. Optimizing one without the other leaves cognitive runway on the table.
Three population studies point to the unglamorous middle layer of healthy aging — where perceived stress, sleep architecture, and muscle composition quietly shape what comes next.
The American Heart Association's updated 0–100 cardiovascular score now includes sleep — and new French cohort data show how few adults actually land in the 'high' zone.
