Adjustable, Comfortable, Anti Snoring Chin Strap Our Snore Chin Support Strap is a simple, affordable anti-snoring device that is worn across the chin and around the top / back of the head. It is used primarily to treat snoring caused by sleeping with the mouth open. Our exclusive adjustable design is a one-piece, two-strap unit, made of stretchy, comfortable SBR and Nylon. Its fully adjustable so you don't need to worry about purchasing different sizes or the strap to feel to loose or to tight! Our Chin Support Strap assists in keeping the jaw and mouth closed, thus forcing the mouth snorer to breathe through the nasal passages. It can be easily positioned for comfort. An additional benefit is that it greatly reduces dry mouth. How it works The affordable Chin Support Strap keeps the slack jaw closed effectively and keeps the mouth shut during sleep. Thanks to this, the mouth stays closed and this forward position of the jaw reduces the risk of the tongue and throat tissues falling back to block the airways. The end result – there is no snoring. This also encourages the snorer to breathe through the nose. About 80% of snorers are open-mouth snorers, so a Chin Support Strap is often an economical treatment. If you are the type who sleeps with the mouth open, this can prove counterproductive – the air entering your throat through the mask escapes out of the mouth and does not perform the intended function of keeping the airways open. This can actually worsen the sleep apnea and therefore, doctors advise sleep apnea patients who sleep with the mouth open to use a chin strap in combination with CPAP therapy.
