How are TSH Schilddrüse and sleep related?

The thyroid and sleep are linked via the hypothalamic-pituitary-thyroid (HPT) axis. TSH (thyroid-stimulating hormone) is secreted in a pulsatile manner, with a nocturnal peak before sleep onset. Sleep deprivation or disruption can alter this rhythm: studies show that sleep loss increases TSH levels, while deep sleep suppresses TSH secretion. Conversely, thyroid dysfunction (hyper- or hypothyroidism) affects sleep quality – e.g., night sweats, restlessness, or fatigue. The effects are moderate and vary individually. A single TSH test is not sufficient to diagnose sleep disorders; clinical evaluation is needed. Caveat: DTC tests (e.g., MyBody-X) measure TSH in blood, but interpretation should be done by a physician, as many factors (stress, diet, medications) influence TSH levels.
