It is not recommended to use a chin strap for snoring without a CPAP mask. By itself, a chin strap or snore guard is an ineffective and potentially dangerous way to prevent snoring. Instead, you may be able to naturally prevent snoring through a few lifestyle changes. Maintaining a healthy weight, sleeping on your back, getting enough sleep (usually 7 to 9 hours), and regularly breathing through your nose have been known to reduce snoring. However, if these methods do not work, you may need to seek further help from a doctor or sleep scientist.
