Genomic instability
DNA damage accumulates over time, leading to mutations and chromosomal abnormalities that drive aging.
Somatic mutations and structural variants corrupt gene function, enable clonal expansions, and raise cancer incidence with age. Persistent DNA damage also activates senescence programs and maladaptive repair responses that spread dysfunction across tissues.
How to minimize genomic instability
- Reduce exogenous damage: UV protection, avoid tobacco, limit alcohol, and minimize unnecessary ionizing radiation.
- Support endogenous repair via metabolic health, consistent sleep, and adequate micronutrients (folate, B12, zinc)—without megadose antioxidant mythology.
- Prioritize interventions with human evidence adjacent to longevity: exercise, weight management, and glycemic control.
- High-risk contexts (strong family cancer history) warrant clinical screening—not consumer genomics alone.
