Learn the Symptoms, Causes, and the Best Ways to Help Yourself or a Loved One
Many people treat snoring as a joke or something they feel embarrassed about. But loud snoring—especially when accompanied by daytime fatigue—may be a sign of sleep apnea, a common disorder in which breathing repeatedly stops and starts as you sleep. Sleep apnea can leave you feeling exhausted during the day, affect your mood and your relationship with your bed partner, and even be dangerous to your health. But there are things you can do to sleep better at night and feel sharper and more energetic during the day. The first step is to overcome any embarrassment you feel about your snoring and learn to recognize the symptoms of sleep apnea.
What is sleep apnea?
Anatomy of a sleep apnea episode
As airflow stops during a sleep apnea episode, the oxygen level in your blood drops. Your brain responds by briefly disturbing your sleep enough to kick start breathing—which often resumes with a gasp or a choking sound. If you have obstructive sleep apnea, you probably won’t remember these awakenings. Most of the time, you’ll stir just enough to tighten your throat muscles and open your windpipe. In central sleep apnea, you may be conscious of your awakenings.
Sleep apnea briefly interrupts your breathing while you’re asleep. These breathing pauses typically last between 10 to 20 seconds and can occur hundreds of times a night, jolting you out of your natural sleep rhythm. As a consequence, you spend more time in light sleep and less time in the deep, restorative sleep you need to be energetic, mentally sharp, and productive the next day. Since sleep apnea only occurs while you’re sleeping, though, many people aren’t aware they have a problem until a bed partner or roommate complains about their snoring. While it can be tempting to make light of your own or someone else’s snoring or to feel self-conscious about your snoring, 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 treatment, however, you can control 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 your 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
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 signs that you have sleep apnea.
|Signs and Symptoms of 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
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. See How to Stop 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.
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.
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.
Exercise regularly. As well as helping you to lose weight, regular exercise can have a major effect on the duration and quality of your sleep. Aerobic and resistance training can help reduce sleep apnea symptoms, while yoga is also good for strengthening the muscles in your airways and improving 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 rest.
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 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 this 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 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.
Treatment options for obstructive sleep apnea include:
- Other breathing devices
- Dental devices
Medications are only available to treat the sleepiness associated with sleep apnea, not the sleep apnea itself.
Option 1: CPAP
Source: Harvard Health Blog
Continuous Positive Airflow Pressure (CPAP) is the most common treatment for moderate to severe obstructive sleep apnea. The CPAP device is a mask-like machine that covers your nose and mouth, providing a constant stream of air that keeps your breathing passages open while you sleep.
If you’ve given up on sleep apnea machines in the past because of discomfort, you owe it to yourself to give them a second look. CPAP technology is constantly being updated and improved, and the new CPAP devices are lighter, quieter, and more comfortable. In many cases, you’ll experience immediate symptom relief and a huge boost in your mental and physical energy.
CPAP tips and troubleshooting
It can take some time to get accustomed to sleeping while wearing a CPAP device. It’s natural to miss sleeping the “old way,” but there are things you can to do make the adjustment easier.
Make sure your CPAP device fits correctly. A correct fit makes a huge difference. Schedule regular appointments with your doctor to check the fit and evaluate your treatment progress.
Ease into it. Start by using your CPAP device for short periods. Use the “ramp” setting to gradually increase air pressure.
Customize the mask, tubing and straps for the right fit. Ask your doctor about soft pads to reduce skin irritation, nasal pillows for nose discomfort, and chinstraps to keep your mouth closed and reduce throat irritation.
Many CPAP devices now come with a built-in humidifier to decrease dryness and skin irritation. Try a special face moisturizer for dry skin.
Try a saline nasal spray or a nasal decongestant for nasal congestion.
Keep your mask, tubing and headgear clean. To ensure maximum comfort and benefit, replace CPAP and humidifier filters regularly and keep the unit clean.
Mask the sound of the CPAP machine. If the sound of the CPAP machine bothers you, place it beneath the bed to reduce the noise and use a sound machine to help you sleep.
Option 2: Other breathing devices
In addition to CPAP, there are other devices that a sleep specialist may recommend for sleep apnea treatment:
Expiratory positive airway pressure (EPAP) single-use devices fit over the nostrils to help keep the airway open and are smaller, less intrusive than CPAP machines and may benefit people with mild-to-moderate obstructive sleep apnea.
Bilevel positive airway pressure (BPAP) devices can be used for those who are unable to adapt to using CPAP, or for central sleep apnea sufferers who need assistance for a weak breathing pattern. This device automatically adjusts the pressure while you're sleeping, providing more pressure when you inhale, less when you exhale. Some BPAP devices also automatically deliver a breath if it detects you haven't taken one for a certain number of seconds.
Adaptive servo-ventilation (ASV) devices can be used for treating central sleep apnea as well as obstructive sleep apnea. The ASV device stores information about your normal breathing pattern and automatically uses airflow pressure to prevent pauses in your breathing while you’re asleep.
Option 3: Dental devices
Most dental devices are acrylic and fit inside your mouth, much like an athletic mouth guard. Others fit around your head and chin to adjust the position of your lower jaw. Two common oral devices are the mandibular repositioning device and the tongue retaining device. These devices open your airway by bringing your lower jaw or your tongue forward during sleep.
Dental devices are only effective for mild to moderate sleep apnea. There are also a number of troubling side effects from using this type of treatment, including soreness, saliva build-up, nausea, and damage or permanent change in position of the jaw, teeth, and mouth.
It’s very important to get fitted by a dentist specializing in sleep apnea, and to see the dentist on a regular basis to monitor any problems and periodically adjust the mouthpiece.
Option 4: Sleep apnea implants
One of the newest treatments for sleep apnea involves the insertion of a pacemaker system that stimulates muscles to keep airways open so you can breathe during sleep. The new treatment has been approved by the FDA in the U.S. for people with moderate to severe obstructive sleep apnea.
Although the technology is relatively new (and expensive), studies suggest it may also benefit people with central sleep apnea.
Option 5: Surgery
If you have exhausted other sleep apnea treatment options, surgery can increase the size of your airway, thus reducing episodes of sleep apnea.
The surgeon may remove tonsils, adenoids, or excess tissue at the back of the throat or inside the nose, reconstruct the jaw to enlarge the upper airway, or implant plastic rods into the soft palate. Surgery carries risks of complications and infections, and in some rare cases, symptoms can become worse after surgery.
Sleep apnea in children
While obstructive sleep apnea can be common in children, it’s not always easy to recognize. In addition to continuous loud snoring, children with sleep apnea may:
- Pause breathing while sleeping, snort, or gasp
- Adopt strange sleeping positions
- Suffer from bedwetting, excessive perspiration at night, or night terrors
- Exhibit daytime sleepiness
- Develop behavioral problems or declining grades
If you suspect sleep apnea in your child, it’s important to consult a pediatrician who specializes in sleep disorders. Left untreated, sleep apnea can affect your child’s learning, mood, growth, and overall health.
Causes and treatment for sleep apnea in children
The most common causes of obstructive sleep apnea in kids are enlarged tonsils and adenoids. A simple adenotonsillectomy to remove the tonsils and adenoids usually corrects the problem. If excess weight is causing your child’s obstructive sleep apnea, there are plenty of ways you can help your child reach and maintain a healthy weight. Your child’s doctor may also recommend using a CPAP or other breathing device.
