Does hyperthyroidism cause difficulty sleeping?

Hyperthyroidism may make it difficult to fall asleep, cause repeated waking, or leave you feeling unrefreshed. A racing heartbeat, warmth, sweating, tremor, restlessness, and persistent thoughts can keep the nervous system activated at bedtime. Sleep loss can then increase daytime irritability and make concentration harder. Difficulty sleeping alone does not identify the cause: stress, pain, irregular routines, caffeine, medicines, and other health conditions can produce a similar pattern.

Keep a steady sleep and wake routine and give yourself a cooler, quiet bedroom. Limit caffeine later in the day and avoid vigorous exercise close to bedtime if it makes your heart race. Write down when sleep trouble began, how often you wake, and whether you notice tremor, sweating, weight change, or palpitations. Book a clinical assessment if symptoms persist; thyroid blood tests can help determine whether thyroid activity is contributing.

Get urgent help if poor sleep occurs with chest pain, fainting, severe breathlessness, confusion, or a very fast or irregular heartbeat. Seek prompt assessment for severe agitation, high fever, or rapidly worsening symptoms. Make a routine appointment when sleep difficulty is ongoing, affects daily functioning, or comes with weight loss, heat intolerance, diarrhoea, or a neck swelling.

Could thyroid activity be contributing to my sleep pattern? Which tests or examinations are appropriate? Could my medicines or stimulants be affecting sleep, and what should I do if palpitations become more noticeable?
