Mouth Tape
Nasal breathing overnight isn't a biohack. It's how you were designed to sleep.
When you breathe through your mouth at night, your body absorbs up to 20% less oxygen — silently, all night, every night. The result: hundreds of micro-arousals your brain registers but you never remember. Cortisol stays elevated. You wake up eight hours later wondering why you're exhausted. CHORDAQ Mouth Tape redirects airflow nasally. More nitric oxide. Stable blood oxygen. Fewer interruptions your nervous system counts as threats.
HRV improvement within 7 nights — or simply, wake up rested
Not suitable for use with diagnosed untreated sleep apnea, severe nasal congestion, or any condition restricting nasal breathing. When in doubt, consult your doctor first.
