Telomere Length
Telomere length measures protective chromosome caps that shorten with aging and stress. Population studies link shorter telomeres to higher disease risk, but one-off tests are limited.
Telomere length refers to protective caps on chromosome ends that shorten with cell divisions and some stressors. Shorter telomeres associate with aging and disease risk in population studies, but single tests are noisy.
Exercise, sleep, and lower chronic stress correlate with healthier telomere maintenance.
Common questions
-
Can you lengthen telomeres with supplements?
Evidence for supplements is weak compared with sleep, exercise, and stress management. Focus on behaviors with stronger functional outcomes before chasing telomere products.
