What role does TSH play in Schlaf?

TSH (thyroid-stimulating hormone) plays a key role in regulating thyroid function, which indirectly affects sleep. Hypothyroidism (elevated TSH) often causes fatigue, hypersomnia, and sleep apnea, while hyperthyroidism (low TSH) can lead to insomnia, restlessness, and poor sleep quality. However, the relationship is not straightforward: many people with normal TSH still experience sleep issues due to circadian disruption or stress. The evidence is human-strong based on clinical endocrinology, but the provided MyBody-X context does not contain specific studies on TSH and sleep. A TSH test alone is insufficient for sleep assessment; comprehensive thyroid panel and clinical evaluation are needed. Caution: Do not self-medicate with thyroid hormones for sleep problems.
