Snoring can be pretty disturbing to people who sleep in the company of snorers, as well as to the snorer himself, though she may not realize it. For instance, some snorers have a condition called obstructive sleep apnea. Their airways become obstructed various times while they’re sleeping, and each time this happens the snorer briefly stops breathing.
