Many people snore in their sleep.
However, some snorers actually stop breathing while sleeping for 30 or more seconds, several times during the night.
This condition is called obstructive sleep apnea (OSA), a life-threatening sleep breathing disorder, and has the following signs:
In addition obstructive apnea, there is another type of apnea syndrome called central sleep apnea.
By contrast, a person with central apnea doesn't make any sound while sleeping. He just stops breathing because the brain forgets to send breathing signals for a couple of seconds.
For more info about obstructive apnea signs, see Symptoms of Sleep Apnea.
Many healthy people stop breathing while sleeping for a second or two.
However, when a person stops breathing during sleep for more than 10 seconds, the situation is abnormal and becomes an apnea episode, also called:
At the beginning of this video you will actually see and hear when a patient stopped breathing while sleeping. If you have obstructive sleep apnea, you will understand how do you sound in sleep:
Severe sleep apnea patients can stop breathing during sleep for up to almost 2 minutes! After this pause, he briefly wakes up gasping and snorting for air, without knowing it.
Some of the patients with sleep apnea wake up during sleep and think they have another problem, such as insomnia or nightmares. Others will think that they are just fine with their sleep and they get mad when someone tells them to stop snoring.
If you know such a person, a good idea is to video-record him with an infrared camera when he's asleep. He might cool down and take measures when he will see how he's breathing stops in sleep for such a long period of time.
There is one more problem in people with sleep apnea: they stop breathing in sleep more than once! In fact, they have many apnea episode, like 200 times per night, and even 900 times per night in most severe cases!
Now, try to stop breathing for 60 seconds (if you can...), then breathe normally for 60 seconds, and hold your breath for another 60 seconds. Can you do this 200 times? Imagine how would you feel in the morning after a full night of apnea events:

Your brain knows that if you stop breathing for more than 2 or 3 minutes and you don't start to breathe again, you can die.
These awakening episodes will save your life, but they do disturb your sleep and cause excessive daytime sleepiness.
Unfortunately, sleep apnea can cause so much damage to your body that some people can even die from it.

The upper pharyngeal airway (the tube from your throat) has 2 purposes:
When used for swallowing, the pharynx has to be relaxed to carry the food. When used for breathing, it has to remain an open and rigid tube like the trachea.
These functions are possible only by having floppy and collapsible muscular tube that is also capable of being held open rigidly by dilator muscles.
However, during sleep, all these muscles relax, so we do normally have some pharyngeal narrowing.
Some people start to snore if the airway is too narrow.
In obstructive apnea, the pharyngeal airway collapses during sleep until is blocking the airway completely.
The are two main causes for these collapses:
Here are some examples of anatomical abnormalities:
Most often the bed partner is the one who triggers the alarm. He or she reports loud snoring, breathing interruptions, or both during your sleep.
A sleep study is necessary to discover if you really have sleep apnea, or other sleep disorders, how severe is it, and the most effective treatment.
Sometimes you can diagnose sleep apnea at home; however, only a sleep study can confirm this.
More strategies for diagnosing sleep apnea:
Fortunately, there are many options to treat sleep apnea, from the most effective but expensive ones, to alternative solutions:
Bottom line... Most of the time you will not remember stop breathing while sleeping. In this case, your bed partner is maybe your only hope in saving your life and your relationship.
