Myth: A DNA test can reliably predict your cardiovascular risk based on sleep genes. Fact: Sleep duration and quality are strong, modifiable risk factors for cardiovascular disease, supported by numerous observational studies. However, genetic variants in genes like CLOCK or PER have only small effects on sleep patterns and even smaller effects on cardiovascular risk. Most consumer DNA tests overstate these links and neglect traditional risk factors such as blood pressure, cholesterol, smoking, and physical activity. A meaningful cardio risk check should include blood pressure measurement, lipid profile, lifestyle assessment, and sleep evaluation (e.g., via questionnaire or actigraphy) – not just genotyping. The evidence for genetic prediction is weak to moderate; clinical relevance remains unclear. Be cautious about overinterpretation: a 'risk gene' for sleep does not automatically mean high heart risk.
