Snoring is mainly caused by obstruction in the air passage when breathing. It can be a result of a plethora of health conditions such as obesity, allergies, or sleep apnea. Some people have it because they have an enlarged palate or tonsil. Although it is not really considered to be a disease, snoring can affect other people who are in the same room with you. And when you wake up, you will feel some sore throat because of repeated restricted breathing throughout the night.
Mouth pieces are now becoming a trend in reducing your tendency to snore. Because the anatomy of your mouth and esophagus directly impacts your sleep, companies have introduced mouth guards that would position your mouth and throat in a way that would stop snoring at night. But you need to consult a dentist to correctly place the mouth piece and avoid swallowing it during sleep. Mouth guards can help relax your palates and throat muscles so you won't snore. There are side effects though such as salivation and jaw pain.
Another product that you might want to consider is the CPAP. It stands for continuous positive airway pressure device which you can wear at night. This device is designed for people who have sleep apnea and who snores a lot when sleeping. It is a mask that you put over your nose and gently pumps air into your air passages in order to solve your snoring problems. The downside is that it is annoying and uncomfortable and can help you lose sleep in the long run.
For a more simple approach to snoring, you can buy nasal strips which are designed to open your airways. These strips may not be effective to some people. You may also consider nasal sprays and throat sprays that would soothe your senses and lubricate the muscles in the throat. Doctors recommend the combo of nasal strips and throat sprays to help curb your snoring. But this may work only for mild cases.
There is also a technique called the Pillar Procedure which can potentially help stop your snoring. In this procedure, small strands of braided rods are stuck into your palate in order to lessen the vibrations of your throat muscles when you snore. But it can lead to discomfort as well as sore throat. Make sure to read the instructions in the label before applying a certain spray or device.
