Can MC4R help with Schlaf?

MC4R (melanocortin 4 receptor) is primarily known for its role in appetite regulation and energy balance. Some studies suggest variants may influence sleep-wake timing or sleep duration, but the evidence is weak and inconsistent. Most findings come from animal models or obesity-related research, not direct sleep studies in humans. There is no validated clinical application for improving sleep via MC4R. DNA tests claiming such links are speculative. For sleep issues, medical evaluation is recommended.
