Breathing & Dry Mouth

Waking up with a dry mouth, a blocked nose, or snoring loud enough to wake a partner all point to the same underlying issue: something is disrupting how you breathe while you sleep.

For some people it’s mouth breathing caused by nasal congestion. For others it’s the airway partially narrowing or collapsing, which shows up as snoring and, in more serious cases, sleep apnea. Dry indoor air can cause similar symptoms without any breathing problem at all. The right fix depends on which one you’re actually dealing with.
