What role does TSH Schilddrüse play in sleep?

TSH (thyroid-stimulating hormone) regulates thyroid hormone release, which controls metabolism and influences sleep regulation. Elevated TSH (e.g., in subclinical hypothyroidism) is associated with poorer sleep quality, longer sleep onset, and more nighttime awakenings. Suppressed TSH (e.g., in hyperthyroidism) can cause restlessness and insomnia. TSH secretion follows a circadian rhythm with a peak during early night; sleep deprivation can disrupt this rhythm. However, a single TSH value from a consumer test is not diagnostic. If sleep issues and abnormal TSH are present, a full thyroid panel (T3, T4, antibodies) and medical evaluation are needed. The evidence linking TSH to sleep is human-strong, supported by clinical studies and endocrine guidelines.
