MyBody-X angle on Schlaf Training

MyBody-X offers DNA and blood tests that can theoretically point to sleep-related factors – e.g., genetic variants in clock genes (PER3, CLOCK) or biomarkers like melatonin and cortisol. However, the evidence for deriving specific sleep training interventions from these data is weak. Sleep hygiene, light exposure, and behavioral routines are far better supported by current research than personalized supplement recommendations based on single SNPs. MyBody-X positions itself as a lifestyle companion, not a medical diagnostic tool. The tests may serve as a prompt to reflect on one's sleep habits, but they do not replace clinical evaluation for sleep disorders. An evidence-based approach would combine actigraphy, sleep diaries, and possibly clinical diagnostics – the genetic add-on is currently exploratory at best.
