What do night sweats feel like with Obstructive Sleep Apnoea?

Sweating may happen during sleep when repeated pauses in breathing trigger brief stress responses and disrupted sleep. You might wake hot, clammy or thirsty, sometimes with a dry mouth or morning headache. A partner may notice loud snoring, choking sounds or pauses in breathing. Daytime sleepiness, poor concentration and irritability can follow broken sleep. These clues can occur for other reasons too, and night sweats on their own do not establish Obstructive Sleep Apnoea.

Ask someone who sleeps nearby whether they have noticed snoring, gasping or breathing pauses. Write down morning symptoms and whether sweating occurs alongside restless sleep. Arrange an appointment if the pattern repeats, especially if you feel sleepy while driving or working. A clinician can review your symptoms and may arrange a sleep assessment. Do not drive when you are too sleepy to stay alert.

Seek prompt advice for persistent daytime sleepiness, repeated choking awakenings, or breathing pauses witnessed during sleep. Get urgent help for severe breathlessness while awake, chest pain, fainting or blue lips. If you already use a breathing device and symptoms are returning, contact your sleep-care team for advice rather than changing settings yourself.

Ask whether your symptoms warrant a sleep study, what information a bed partner should record, and how to reduce safety risks from daytime drowsiness. Ask how treatment choices might affect sweating, snoring and morning symptoms.
