What does excessive sweating feel like with obstructive sleep apnoea?

Sweating associated with obstructive sleep apnoea usually happens during sleep, so you may discover it on waking rather than feel the episode begin. Your neck, chest, back, or whole body may feel damp, and your sleepwear or sheets may need changing. The night can include snoring, gasping, choking sounds, repeated awakenings, dry mouth, or morning headache. A bed partner may notice pauses in breathing even when you do not.

During the day, disrupted sleep may leave you unusually tired, irritable, foggy, or less alert. Night sweating has many possible explanations, including a warm bedroom, medicines, infection, or other health conditions. The combination with loud snoring or witnessed breathing pauses deserves a clinical assessment rather than a conclusion based on sweating alone.

Ask a bed partner what they observe and write down waking symptoms, snoring, gasping, and morning headaches. Keep the bedroom comfortably cool, but do not use this alone to explain persistent episodes. Arrange an appointment to discuss whether a sleep assessment is appropriate. If you have been prescribed a sleep-apnoea device, use it as directed and report ongoing symptoms or difficulty tolerating it.

Seek medical advice for repeated night sweats with loud snoring, witnessed pauses, gasping, or significant daytime sleepiness. Avoid driving when you are struggling to stay awake. Get urgent help for severe breathing difficulty, chest pain, blue lips, fainting, or confusion. A clinician can assess breathing during sleep and consider other causes of night sweating.

Could my night sweating be related to disrupted breathing? Should I have a sleep study? What observations should my bed partner record? How can I reduce daytime sleepiness safely?
