There are over 300 patients filed for anti-snoring devices. Here is a list of some with their rationale. Evidence for most of these devices are lacking, so I will introduce them in general terms. I do not endorse any product introduced.
The Snore Ball
The concept of the snore ball is to force the snorer to sleep on his or her side. It was invented over 100 years ago and there are multiple versions now available. If you are someone who only snores when on your back, it may be something to consider. Sleeping on the side may force someone to close their mouth and may help prevent the tongue and palate from narrowing the airway.
You can make your own snore ball by sewing a pocket in the back of their night shirt which is large enough to place a ping-pong ball or golf wiffle ball.
Snore Pillows
There are many ‘snore pillows’ now available. Some of them suggest they stop snoring by extending the neck, stretching the tissue in the throat so it is stiffer. Others are designed to force someone to sleep on their side, similar to the snore ball concept. There is no good evidence that either of these methods work, although the pillows which encourage you to sleep on your side, are getting better reviews.
Snore Collars
Snore collars are designed to try to keep the mouth closed and neck extended. The idea is that it also stretches the tissues of the neck, making them stiffer and reducing snoring. They also report it helps keep the tongue forward. Again, I am unaware of any solid evidence, however there are multiple testimonials.
Nasal Dilators
This category includes both nasal strips and internal dilators. These open the nasal valve area (where most airway resistance occurs) to encourage nasal breathing. Nasal strips stick to the skin of the nose, pulling it outwards and improving nasal airflow.
Nasal dilators are re-usable devices inserted into the nostrils. There are multiple dilators available, some just open the nostrils, while others are inserted deeper into the nose to open the nasal valve area. This can provide even better nasal airflow and improve snoring if nasal obstruction is the cause. The Max-Air Nose Cones are an example of these.
Throat Sprays
Throat sprays deliver natural lubricating oils to the back of the throat. This is marketed as being able to reduce the throat tissues ability to stick to each other and therefore to reduce vibration (snoring). There have been some contradictory studies on how effective this is. Properly done studies do not show any significant impact. Using them too frequently can cause throat irritation and worsening of snoring.
