What Is It?
Sleep apnea is a disorder that causes people to stop breathing for short periods during sleep. These periods are called apneas. Apneas usually last between 10 and 30 seconds. In severe cases, apneas can happen many hundreds of times each night. People with untreated sleep apnea are more likely to develop high blood pressure.
Apneas disrupt a person's ability to get a good night's sleep, making them less alert during the day. This can lead to accidents. People with untreated sleep apnea are up to seven times more likely to be involved in motor vehicle accidents.
