What to watch with TSH Schilddrüse and sleep?

TSH (thyroid-stimulating hormone) is a screening marker for thyroid function. Elevated TSH suggests hypothyroidism, which can cause fatigue, low energy, and poor sleep quality. Low TSH indicates hyperthyroidism, often linked to insomnia, restlessness, and night sweats. However, TSH alone is not diagnostic – free thyroid hormones (fT3, fT4) and antibodies should also be measured. Sleep issues are multifactorial (stress, lifestyle, other conditions). An abnormal TSH should be evaluated by a doctor before taking supplements or making dietary changes. Evidence is based on clinical practice, not from the provided context. Caution: consumer hormone tests may show fluctuations; a single reading is not conclusive.
