HOW WE HELP: Our anti-snoring chin straps help alleviate the problem of open-mouth snoring and sleep apnae by supporting your chin during sleep, restricting the inflow of air into your throat, reducing throat vibration and thus reducing snoring frequency. By keeping the mouth closed, our anti snoring chin strap prevents the over-relaxation and the closure of upper airway, makes sure that the body takes in enough oxygen during sleep. Of course, you'll get better sleep, and so will your partner.
