Air pollution and accelerated aging: What PM2.5 does to your cells
How does PM2.5 pollution affect biological age? Learn evidence on epigenetic clocks, telomeres, inflammation, HEPA filters, and safer daily habits.
Alcohol and biological aging: What the research actually shows
Alcohol and biological aging: how drinking affects telomeres, epigenetic clocks, liver markers, sleep, and the newer evidence on moderate drinking.
Aortic stiffness and pulse wave velocity: The gold standard of vascular age
Learn how pulse wave velocity reflects aortic stiffness and vascular age, what values mean, how testing works, and which habits may improve arterial health.
Atrial fibrillation and aging: Why your heart rhythm is a longevity signal
AFib rises with age and raises stroke risk. Learn how HRV, sleep apnea, blood pressure, alcohol, and wearables shape heart-rhythm longevity.
Blue light and circadian disruption: How screens are aging you at night
Blue light at night can suppress melatonin, shift circadian timing, disrupt sleep, and affect metabolic health. Learn the evidence and fixes.
Carotid intima-media thickness: Measuring your arterial age directly
CIMT ultrasound measures carotid artery wall thickness, a vascular-aging marker. Learn what results mean, what guidelines say, and how to track risk.
Endothelial function: The vascular aging test your doctor doesn't order
Endothelial function shapes nitric oxide, blood flow, clotting, and vascular aging. Learn flow-mediated dilation testing and vessel-protective habits.
Glycine and collagen: The anti-aging amino acids that decline with age
Glycine supports collagen, glutathione, sleep, and connective tissue. Learn what studies show, practical food sources, and safe supplement context.
Heart rate recovery after 60 seconds: The deep dive into autonomic aging
New research shows that the first 10-60 seconds after exercise reveal your autonomic age. Learn what each recovery window means, why vagal tone declines, and advanced strategies to improve HRR.
