The second you lose consciousness
your body defaults to whatever breathing
pattern it knows. For most that's
mouth breathing. No amount of willpower
changes what happens while you're asleep.
Mewism seals your mouth before you lose
control — so your body has no choice
but to breathe through your nose
all night long.

Nasal breathing produces nitric
oxide — a molecule that widens blood
vessels, increases oxygen delivery and
kills airborne bacteria. When you mouth
breathe you bypass this entirely.
Every night you sleep with your mouth
open you miss out on 8 hours of nitric
oxide production. Mewism ensures your
nose does the work it was designed to do.

Chronic mouth breathing during
sleep relaxes the jaw, elongates facial
muscles and works against your facial
structure for 8 hours straight.
It happens every night without you
knowing. Sealing your mouth with Mewism
forces your jaw to stay engaged and
your airway to function the way it
was designed — while you sleep.

Studies suggest the majority of
adults mouth breathe during sleep without
realising it. Dry mouth in the morning,
poor sleep quality and low energy are
all signs. One strip of Mewism before
bed is the simplest intervention
available. No routine changes.
No effort. Just seal and sleep.
