What is sleep apnea?
Sleep apnea is a common but serious sleep disorder where your breathing is briefly interrupted when you’re asleep. If you have sleep apnea, you’re probably not aware of these short breathing pauses that occur hundreds of times a night, jolting you out of your natural sleep rhythm. All you know is that you don’t feel as energetic, mentally sharp, or productive during the day as you should do.
The most common type of sleep apnea—obstructive sleep apnea—occurs when the airway is blocked, causing pauses in breathing and loud snoring. Since sleep apnea only occurs while you’re sleeping, you may only discover you have a problem when a bed partner or roommate complains about your snoring. Though you may feel self-conscious about it or tempted to just make light of your snoring, it’s something you shouldn’t ignore. Sleep apnea can take a serious toll on your physical and emotional health.
The chronic sleep deprivation caused by sleep apnea can result in daytime sleepiness, slow reflexes, poor concentration, and an increased risk of accidents. Sleep apnea can cause moodiness, irritability, and even lead to depression, as well as serious physical health problems such as diabetes, heart disease, liver problems, and weight gain. With the right treatment and self-help strategies, however, you can control your snoring and the symptoms of sleep apnea, get your sleep back on track, and feel refreshed and alert during the day.
Types of sleep apnea
- Obstructive sleep apnea is the most common type of sleep apnea. It occurs when the soft tissue in the back of the throat relaxes during sleep and blocks the airway, often causing you to snore loudly.
- Central sleep apnea is a much less common type of sleep apnea that involves the central nervous system, occurring when the brain fails to signal the muscles that control breathing. People with central sleep apnea seldom snore.
- Complex sleep apnea is a combination of obstructive sleep apnea and central sleep apnea.
Signs and symptoms of sleep apnea
It can be tough to identify sleep apnea on your own, since the most prominent symptoms only occur when you’re asleep. But you can get around this difficulty by asking a bed partner to observe your sleep habits, or by recording yourself during sleep. If pauses occur while you snore, and if choking or gasping follows the pauses, these are major warning signs that you have sleep apnea.
Major warning signs
Loud and chronic snoring almost every night
- Choking, snorting, or gasping during sleep
- Pauses in breathing
- Waking up at night feeling short of breath
- Daytime sleepiness and fatigue, no matter how much time you spend in bed
Other warning signs
- Waking up with a dry mouth or sore throat
- Insomnia or nighttime awakenings; restless or fitful sleep
- Going to the bathroom frequently during the night
- Forgetfulness and difficulty concentrating
- Uncharacteristic moodiness, irritability, or depression
- Morning headaches
Is it sleep apnea or just snoring?
Not everyone who snores has sleep apnea, and not everyone who has sleep apnea snores. So how do you tell the difference between normal snoring and a more serious case of sleep apnea?
The biggest telltale sign is how you feel during the day. Normal snoring doesn’t interfere with the quality of your sleep as much as sleep apnea does, so you’re less likely to suffer from extreme fatigue and sleepiness during the day.
Record yourself sleeping or ask your sleep partner to keep track of your snoring, noting how loud and frequent it is, and if you’re gasping, choking, or making other unusual sounds. Even if you don’t have sleep apnea, a snoring problem can get in the way of your bed partner’s rest and affect your own sleep quality and health. However, there are effective solutions to snoring.
See a doctor immediately if you suspect sleep apnea
Sleep apnea can be a potentially serious disorder, so contact a doctor immediately if you spot the warning signs. An official diagnosis of sleep apnea may require seeing a sleep specialist and taking a home- or clinic-based sleep test.
Do you have sleep apnea?
These questions can help you and your physician figure out if you should be tested for sleep apnea.
Interpreting the score:
0 to 5: Low probability of sleep apnea. You’re sleep problems are more likely to be caused by something other than sleep apnea. Consult your doctor for a diagnosis.
6 to 8: It’s uncertain whether you have sleep apnea. You and your doctor should decide the next step based on your medical history.
9 +: You may have sleep apnea. You are a good candidate for a sleep study and should see your doctor immediately

Sleep apnea causes
While anyone can have sleep apnea, you have a higher risk for obstructive sleep apnea if you’re:
- Overweight, male, with a family history of sleep apnea
- Over the age of 50, a smoker, affected by high blood pressure
- Black, Hispanic, or a Pacific Islander
- Someone with a neck circumference greater than 15.75 inches (40 cm)
Other physical attributes that put you at risk for obstructive sleep apnea include a deviated septum, receding chin, or enlarged tonsils or adenoids. Your airway may be blocked or narrowed during sleep simply because your throat muscles tend to relax more than normal. Allergies or other medical conditions that cause nasal congestion and blockage can also contribute to sleep apnea.
Central sleep apnea causes
Like obstructive sleep apnea, central sleep apnea is more common in males and people over the age of 65. However, unlike obstructive sleep apnea, central sleep apnea is often associated with serious illness, such as heart disease, stroke, neurological disease, or spinal or brainstem injury. The first step in treating central sleep apnea is to treat the existing medical conditions that are causing it.
Some people with obstructive sleep apnea can develop central sleep apnea when they’re being treated with positive airway pressure (PAP) devices.
While a diagnosis of sleep apnea can be scary, it is a treatable condition. In fact, there are many things you can do on your own to help, particularly for mild to moderate sleep apnea. Home remedies and lifestyle modifications can go a long way in reducing sleep apnea symptoms. However, they should not replace medical evaluation and treatment.
Lifestyle changes to reduce sleep apnea symptoms
Lose weight. People who are overweight have extra tissue in the back of their throat, which can fall down over the airway and block the flow of air into the lungs while they sleep. Even a small amount of weight loss can open up your throat and improve sleep apnea symptoms.
Quit smoking. Smoking contributes to sleep apnea by increasing inflammation and fluid retention in your throat and upper airway.
Avoid alcohol, sleeping pills, and sedatives, especially before bedtime, because they relax the muscles in the throat and interfere with breathing.
Avoid caffeine and heavy meals within two hours of going to bed.
Maintain regular sleep hours. Sticking to a steady sleep schedule will help you relax and sleep better. Sleep apnea episodes decrease when you get plenty of sleep.
Bedtime tips for preventing sleep apnea
Sleep on your side. Avoid sleeping on your back which makes it more likely for your tongue and soft tissues to obstruct your airway. Some people only experience sleep apnea when sleeping on their back.
The tennis ball trick. To keep yourself from rolling onto your back while you sleep, sew a tennis ball into a pocket on the back of your pajama top. Or wedge a pillow stuffed with tennis balls behind your back.
Prop your head up. Elevate the head of your bed by four to six inches, or elevate your body from the waist up by using a foam wedge or special cervical pillow.
Open your nasal passages at night by using a nasal dilator, saline spray, breathing strips, or a nasal irrigation system (neti pot).
Tighten the muscles that keep the mouth closed. Try chewing gum or holding a pen between your teeth for about 10 minutes before bedtime, or until your jaw starts to ache.
Singing can increase muscle control in the throat and soft palate, reducing snoring and sleep apnea caused by lax muscles.
Playing the didgeridoo (native Australian wind instrument) can strengthen the soft palate and throat, reducing daytime sleepiness and snoring in people with moderate sleep apnea.
Throat and tongue exercises may reduce the severity of sleep apnea by strengthening the muscles in the airway, making them less likely to collapse. It may take several weeks before you start to notice the benefits.
Try these exercises:
- Press your tongue flat against the floor of your mouth and brush top and sides with a toothbrush. Repeat brushing movement five times, three times a day.
- Press the length of your tongue to the roof of your mouth and hold for three minutes a day.
- Place a finger into one side of your mouth. Hold the finger against your cheek while pulling the cheek muscle in at same time. Repeat 10 times, rest, and then alternate sides. Repeat this sequence three times.
- Purse your lips as if to kiss. Hold your lips tightly together and move them up and to the right, then up and to the left 10 times. Repeat this sequence three times.
- Place your lips on a balloon. Take a deep breath through your nose then blow out through your mouth to inflate the balloon as much as possible. Repeat five times without removing balloon from your mouth.
- Gargle with water for five minutes, twice a day.
- Lightly hold your tongue between your teeth. Swallow five times. Repeat this five times a day.Sleep apnea treatment options
If your sleep apnea is moderate to severe, or you’ve tried self-help strategies and lifestyle changes without success, a sleep doctor may help you find an effective treatment. Treatment for sleep apnea has come a long way in recent times, so even if you were unhappy with sleep apnea treatment in the past, you may now find something that works for you.
Treatments for central and complex sleep apnea usually include treating any underlying medical condition causing the apnea, such as a heart or neuromuscular disorder, and using supplemental oxygen and breathing devices while you sleep.
