Mouth breathing at night is more than a detail. Anyone who constantly breathes through their mouth often wakes up with a dry throat, is more likely to snore and feels less rested. The cause is often - but not always - a nose that doesn't let in enough air at night.

What happens when you breathe through your mouth?

The nose filters, humidifies and warms the air. If it fails, untreated room air flows through the mouth:

  • Mucous membranes dry out
  • Throat scratches in the morning
  • Snoring noises may increase
  • Sleep seems more superficial

More basics: Why nasal breathing is more important than you think.

What nasal plasters can do - and what they can't

A nasal plaster forces Don't let yourself breathe through your nose. It eases them by lifting the nostrils. For many people, this is enough to allow them to breathe through their nose longer at night - especially if the blockage is mechanical and narrow, not deep anatomical.

It is not a substitute for treatment for sleep apnea or severe respiratory diseases.
