Risks and limits of Longevity Alltag

The idea of optimizing daily life through 'longevity' measures is popular but warrants caution. Many interventions—from genetic tests to supplements and specialized diets—are based on preliminary data or animal models. Evidence for actual lifespan extension in humans is generally weak to moderate. For example, genetic variants in clock genes (e.g., PER, CLOCK) explain less than 5% of chronotype variance; environmental factors like light exposure, shift work, and stress dominate. A DNA test alone cannot reliably determine your optimal daily schedule or sleep quality. Similarly, supplements (e.g., resveratrol, NMN) often lack long-term human trials. Risks include overinterpretation, unnecessary costs, and potential drug interactions. Moreover, an excessive focus on 'optimization' can create undue pressure or delay proper medical evaluation—for instance, persistent fatigue despite adequate sleep warrants a doctor's visit, not just a genetic test. Responsible use means treating results as clues, not diagnoses, and always consulting a clinician for health decisions.
