Can ADH1B help with Schlaf?

ADH1B encodes alcohol dehydrogenase, an enzyme that metabolizes alcohol. There is no direct scientific evidence that ADH1B variants improve or worsen sleep. Some variants (e.g., rs1229984) cause alcohol intolerance, which may indirectly reduce alcohol intake and thereby improve sleep quality in those who would otherwise drink heavily. However, this is a behavioral consequence, not a direct genetic effect on sleep regulation. Consumer DNA tests that market ADH1B as a 'sleep gene' overstate the evidence. For sleep issues, proven interventions include good sleep hygiene, stress management, melatonin, and addressing medical conditions like sleep apnea. Genetic testing for ADH1B is not recommended for sleep concerns. Evidence: unclear/marketing. Sources: none from provided context.
