Snoring is a common sleep-related problem that affects millions of people worldwide. While many consider it a harmless nighttime nuisance, frequent snoring can sometimes indicate an underlying health issue. Understanding why people snore , what causes it, and how it can be treated is important for improving sleep quality and overall health. Snoring is the sound of obstructed breathing, which can be caused by some basic factors, such as poor muscle tone, bulky throat tissue, or a long soft palate or uvula, according to Johns Hopkins.
