Can Insulin help with sleep?

Insulin is a key hormone in glucose metabolism. Some mechanistic research suggests insulin may influence circadian rhythms and sleep regulation via hypothalamic pathways, but robust clinical evidence for insulin as a sleep aid is lacking. The provided context does not address this question directly. Using insulin without medical indication (e.g., diabetes) is dangerous and can cause hypoglycemia. For sleep improvement, focus on established interventions: sleep hygiene, CBT-I, and addressing underlying conditions like sleep apnea or insulin resistance. Evidence grade: unclear.
