What to watch with Fitness | LifestyleCheck and sleep?

The available context on 'Fitness | LifestyleCheck' and sleep is limited. MyBody-X offers blood tests for hormones (TSH, fT3, fT4, testosterone, estradiol, progesterone, SHBG) and nutrients (ferritin, iron, vitamin B12) – these can indirectly affect sleep quality. No direct sleep marker (e.g., melatonin) is mentioned in the context. Sleep is influenced by many factors (stress, light, genetics). Genetic tests for sleep are generally weakly supported. Practical advice: For sleep issues, focus on lifestyle and check blood markers like iron, vitamin D, and cortisol. Caveat: Not a clinical diagnosis; consult a doctor for persistent problems.
