What to watch with CLOCK and Langlebigkeit?

The CLOCK gene variant (e.g., rs1801260) is linked to circadian rhythms and possibly longevity, but the scientific evidence is weak. Studies show associations with sleep patterns, metabolism, and cardiovascular risk, but no direct causal link to lifespan extension. The effects of single SNPs are small and highly context-dependent (diet, light exposure, lifestyle). Consumer DNA tests for CLOCK and longevity are not clinically validated. Instead, focus on evidence-based measures: consistent sleep schedule, adequate daylight exposure, avoiding shift work, and a balanced diet. Longevity is influenced by many factors, not a single gene.
