Can changing your pillow improve sleep apnea?

Research indicates that if a pillow can raise the height of the head in the center while lowering the height on both sides, thus creating a unique mountain shape, it can effectively increase the proportion of people sleeping on their side at night, thereby improving the phenomenon of breathing apnea and reducing the frequency of snoring.

However, pillows have no effect on treating sleep apnea. Therefore, choosing a suitable pillow may improve the symptoms, but it is more important to seek help from a professional doctor, follow the doctor's advice, and actively treat the condition.

(The book "Buying a Good Pillow" mentions that sleeping on your side helps keep your airway clear, but adjusting the pillow to the appropriate height also makes it less likely for you to experience breathing apnea when sleeping on your back.)
