Evidence check: Menopause Check in the context of Schlaf

The evidence for a Menopause Check in the context of sleep is weak. Most commercial tests (e.g., salivary hormone panels or DNA-based menopause profiles) rely on markers like estradiol, progesterone, or FSH, but their fluctuations during perimenopause correlate poorly with specific sleep disturbances. Sleep issues in menopause are multifactorial: hot flashes, mood changes, lifestyle, and sleep hygiene are more influential than single hormone levels. The provided context contains no validated studies linking menopause checks to sleep. Some DNA tests claim to capture individual hormone regulation, but the effects of tested SNPs are small and not sleep-specific. Therefore, the predictive value of such checks for sleep quality is low. Medical evaluation (e.g., sleep study, clinically relevant hormone assessment) is recommended. Evidence: marketing/unclear.
