What should I know about was bedeutet biohacking?

Biohacking refers to the deliberate use of science, technology, and self-experimentation to optimize health, performance, and longevity. It includes areas like nutrigenetics, sleep optimization, microbiome analysis, and hormone regulation. The MyBody-X contexts show that DNA tests for CLOCK/PER genes can offer clues about chronotype, but effect sizes are small and lifestyle factors (e.g., morning light) are more impactful. Micronutrient blood tests (zinc, vitamin D) are reliable, but blood levels don't always reflect tissue stores. Biohacking can be useful, but it carries risks: without medical guidance, misinterpretations can lead to unnecessary supplementation or neglect of underlying conditions. Evidence is often mechanistic or observational; randomized controlled trials are lacking for many DIY approaches. A critical, evidence-based approach is essential.
