According to a study conducted in Brazil by researchers at the Federal University of São Paulo (UNIFESP) with participants from the São Paulo Epidemiological Sleep Study (EPISONO 2018), people with hypothyroidism experience more frequent and severe obstructive sleep apnea (OSA). The results also indicated that patients receiving hormone replacement therapy for thyroid dysfunction slept longer and spent more time in deep sleep.
