Scent Triggers Sniff Reflex To Restart Breathing
- Appscent uses scent to trigger a sniff reflex that restarts breathing during sleep events.
- Clinical trials showed severity of sleep apnea can drop by one category after the first night.
Scents Improve Breathing Without Waking Partners
- Scent stimulation can improve breathing without waking nearby sleepers and may deepen REM.
- Appscent positions the product as a 'couples therapy' device addressing snoring and partner sleep quality.
Train Nasal Breathing With Daytime Biofeedback
