Can Fitness | LifestyleCheck help with Schlaf?

Whether the Fitness | LifestyleCheck from MyBody-X can help with sleep is not supported by strong evidence. The test examines SNPs related to fitness, recovery, and general wellness, potentially including circadian rhythm genes like CLOCK or PER3. However, effect sizes are small, and sleep quality is influenced by many lifestyle and environmental factors (light, stress, diet, sleep hygiene). MyBody-X markets the test as lifestyle inspiration, not medical advice. Under German law (GenDG), such tests are not intended for diagnosing or treating sleep disorders. For persistent sleep issues, consulting a physician or sleep specialist is recommended. The test may offer general awareness but cannot replace evidence-based sleep interventions.
