Snoring is very common and can be caused by many different things. About 45% of normal adults snore at least sometimes. People who snore may be the topic of jokes at family picnics but snoring is actually pretty serious business. First, it's very loud and disruptive. A snoring spouse often keeps the other person from a good quality of sleep, which could lead to having to sleep in separate bedrooms.
Not only is snoring annoying, but 75% of people who snore have obstructive sleep apnea which is caused when breathing is disrupted during sleep for short periods. DSA increases the risk of heart disease. You should go see your doctor if you or your spouse snores to see if there is a larger underlying cause.
