Telomere Age Estimator
Telomeres protect your DNA and shorten with age. Your lifestyle can speed up or slow down this process. See where you stand.

Factor breakdown:
Telomere age is an estimate based on lifestyle factors known to affect telomere shortening rate. For actual measurement, consider a clinical telomere length test.
Common questions
What are telomeres?
Telomeres are protective caps at the ends of your chromosomes, like the plastic tips on shoelaces. Each time a cell divides, telomeres get slightly shorter. When they become too short, cells can no longer divide properly, leading to aging, disease, and cell death.
Can you lengthen your telomeres?
While you cannot dramatically regrow telomeres, research shows that healthy lifestyle habits can slow telomere shortening and, in some cases, modestly increase telomere length. Regular exercise, stress reduction, quality sleep, and a whole-food diet all positively affect telomere maintenance.
What is the link between telomeres and cancer?
The relationship is complex. Short telomeres increase the risk of cells becoming cancerous due to chromosomal instability. However, cancer cells often activate telomerase to become immortal. Maintaining healthy telomere length through lifestyle factors is generally protective.
How is telomere length measured?
Clinical telomere testing uses a blood sample analyzed with techniques like qPCR or Flow-FISH. Companies like TeloYears and Life Length offer consumer tests. Results show your average telomere length compared to age-matched populations. Costs range from $100-$500.
