Millions of people worldwide suffer from the common yet dangerous condition known as Sleep Apnea. It happens when you stop breathing or if your breathing is very shallow during sleep, causing you to wake up briefly and repeatedly throughout the night.

However, many people are unaware that they have sleep apnea, or they ignore the signs and do not seek treatment. This can have detrimental effects on their health and general well-being, as sleep apnea may raise the chance of several chronic conditions, including diabetes, heart disease, stroke, and excessive blood pressure.

This is why it is essential to understand and manage sleep apnea and to seek professional help if you suspect that you or your loved ones have this condition.

Symptoms of Sleep Apnea

Sleep apnea can cause various symptoms that affect your sleep quality and daily functioning. Loud snoring is the most typical sign of sleep apnea, which can disturb your partner or anyone who shares the bedroom with you. However, not everyone with sleep apnea snores, or all snorers, have obstructive sleep apnea.

Another common symptom is experiencing moments when breathing stops, or you gasp for air during sleep. These episodes can last from a few seconds to a few minutes and occur hundreds of times per night. They may also cause you to momentarily wake up repeatedly, disrupting your sleep cycle and preventing you from getting enough deep and restorative sleep.

Additional signs of sleep apnea are dry lips, headaches, insomnia, hypersomnia, difficulty paying attention, and irritability. These symptoms can result from the lack of oxygen and the poor sleep quality caused by sleep apnea. They can also affect your mood, memory, concentration, productivity, and performance at work or school.

If you experience these symptoms, you should not ignore them or dismiss them as usual signs of ageing or stress. Seek a doctor’s advice and follow the treatment plan suggested by them.

Causes of Obstructive Sleep Apnea (OSA)

The type that occurs most frequently is obstructive sleep apnea (OSA), which happens when something blocks your airway while you sleep. There are numerous potential causes of this, including:

• Excess Weight: Excess weight can put pressure on your throat and chest and cause fat deposits around your neck. It can narrow your airway and make it harder for you to breathe.
• Having a narrow airway: Some people are born with a naturally small or narrow airway or have a lower jaw that is set back. It can make their airway more susceptible to collapse or obstruction.
• Having enlarged tonsils or adenoids: These tissues sit at the back of your throat and behind your nose. They help fight infections but can grow too large and block your airway, especially in children.
• Smoking: Smoking can irritate and inflame your throat and airway and cause them to swell. It can also damage the cilia, the tiny hairs that help clear mucus and debris from your airway. This can increase the likelihood of snoring and sleep apnea.

Central Sleep Apnea (CSA)

Central sleep apnea (CSA) happens when your brain is unable to communicate the appropriate signals to your breathing muscles during the night. There are several possible reasons for this, such as:

• Taking opioid pain medications: Although opioids are potent medications that can reduce pain, they can also affect your breathing. They can slow down your breathing rate and make it shallow. Additionally, they may hinder the brain’s capacity to sense the oxygen level in your blood and adjust your breathing accordingly.
• Heart conditions: Some heart conditions, such as atrial fibrillation or congestive heart failure, can affect blood circulation and oxygen delivery. It can make your brain less responsive to changes in your oxygen level and breathing needs. It may also result in an accumulation of fluid in your lungs, making your breathing irregular.
• Living at high altitudes: When you live or travel to high altitudes, the air is thinner and has less oxygen. It can make your body work harder to get enough oxygen and cause your breathing to become faster and deeper. However, your brain may not adjust to this change and may still signal your breathing muscles to slow down or stop. It can cause central sleep apnea.

Effective Treatments for Sleep Apnea

Several popular sleep apnea treatments include:

• Lifestyle modifications: These are changes you can make in your daily habits and routines, such as losing weight, quitting smoking, sleeping on your side, avoiding alcohol and sedatives, practising good sleep hygiene, and using a humidifier. These changes can help you reduce or eliminate the symptoms and complications of sleep apnea, especially if you have mild or moderate OSA. However, they may not be enough to treat severe or complex cases of sleep apnea and may require advanced intervention.
• CPAP: The acronym CPAP represents Continuous Positive Airway Pressure. It is the most popular and successful sleep apnea treatment, especially for OSA. It entails covering your nose, mouth, or both with a mask connected to a machine that delivers constant air pressure to your airway. This pressure keeps your airway open and prevents it from collapsing or narrowing while you sleep. This way, you can breathe normally and avoid the episodes of stoppage in breathing and the drops in oxygen level.
• Oral appliances: These are devices you wear in your mouth while you sleep, like a tongue-retaining device or a mandibular advancement device (MAD). They function by pushing your tongue or lower jaw forward and creating more space for your airway. Oral appliances are a viable substitute for people who cannot tolerate CPAP therapy or who have mild or moderate OSA. They can also be easier to use, carry, and maintain than CPAP machines.
• Surgery: This treatment involves removing or altering some of the tissues or structures that cause your airway to collapse or narrow while you sleep, such as your tonsils, adenoids, uvula, soft palate, or tongue. Surgery can be a last resort for people who have severe or complex cases of sleep apnea or who have failed to respond to other treatments. Surgery can also be a permanent solution for some people, as it can cure their sleep apnea completely.
• Supplemental oxygen: Supplemental oxygen involves using a device that delivers extra oxygen to your lungs. When you sleep, a nasal cannula or an oxygen mask acts as a supplemental oxygen which helps increase the oxygen level in your blood and prevent the complications of low oxygen, such as high blood pressure, heart disease, or stroke. Supplemental oxygen can be used alone or with other treatments, such as CPAP therapy or oral appliances. It can be a good option for people with low CSA or OSA levels.

Living Well with Sleep Apnea

Sleep apnea can be challenging, but it does not mean you cannot live a fulfilling life. There are many things that you can do to cope with sleep apnea and improve your quality of life, such as:

• Losing weight: Overweight or obese individuals may benefit from weight loss. Weight loss can help reduce the pressure on your throat and chest and the fat deposits around your neck. It can improve your breathing and reduce the severity of your sleep apnea.
• Quitting smoking: It can be beneficial to stop smoking because it will reduce the inflammation and swelling of your throat and airway and the damage to the cilia. It can improve your airflow and prevent snoring and episodes of stop breathing caused by sleep apnea.
• Sleeping on your side: If you sleep on your back, your tongue, soft palate, or throat muscles can fall back and block your airway. It can worsen your sleep apnea and make you snore louder. Sleeping on your side can help you keep your airway open and prevent obstruction.  
• Avoiding alcohol and sedatives: Alcohol and sedatives can relax your throat and airway muscles and make them more likely to collapse or narrow while you sleep. It can worsen your sleep apnea and make you stop breathing more often. It can also interfere with your brain’s signals to your breathing muscles and make them less responsive to changes in your oxygen level.
• Practising good sleep hygiene: A collection of practices and rituals known as “sleep hygiene” can improve sleep quality and quantity. Some sound sleep hygiene practices include a regular sleep schedule, keeping your bedroom dark, quiet, and comfortable, avoiding caffeine, nicotine, and heavy meals before bed, unwinding and resting, and keeping devices and displays away for at least an hour before sleep.
• Using a humidifier: A humidifier raises the moisture in your room’s air and prevents your nose and throat from drying. It can reduce your airway’s irritation, congestion, and inflammation and improve your breathing and comfort while you sleep. You can incorporate essential oils, like lavender, chamomile, or eucalyptus, into your humidifier to create a soothing and relaxing atmosphere.

Myth: Only older or overweight people have sleep apnea.

Reality: Sleep apnea can affect anyone, regardless of age, gender, or weight. Although sleep apnea is more common in older and overweight people, it can also occur in young and thin people. Even children can have sleep apnea, significantly more so if they have enlarged tonsils or adenoids.

Myth: Snoring is harmless and normal.

Reality: Snoring can indicate a potentially serious problem—the snoring sound results from air flowing through a narrowed or obstructed airway, causing the tissues to vibrate. Therefore it can be a significant reason for sleep apnea, it cannot be ignored but it is also true that people with sleep apnea may have silent pauses in breathing or shallow breathing without making any noise. Therefore, in any case, you should not ignore or dismiss snoring as harmless or normal.

Myth: There is no danger associated with sleep apnea.

Reality: Sleep apnea can have severe consequences for the health and quality of life of a person and increase the risk of various chronic diseases. It can lower the oxygen level in your blood and disrupt the quality and quantity of your sleep. It can affect your mood, memory, concentration, productivity, and performance.

Moreover, sleep apnea can cause or worsen various health problems, such as high blood pressure, diabetes, liver problems, metabolic syndrome, and cardiovascular problems. These issues may result in major side effects such as a heart attack, stroke, or even death. Therefore, you should not underestimate or neglect sleep apnea, and get diagnosed and treated as soon as possible.

Myth: CPAP is the only treatment option for sleep apnea.

Reality: CPAP is the most common and effective treatment option for sleep apnea, but other alternatives are also available, depending on the type and severity of the condition. CPAP therapy can help you improve your sleep quality, daytime alertness, blood pressure, and heart health. However, if you cannot tolerate CPAP therapy or if you have mild or moderate OSA, you may be able to use other treatment options, such as oral appliances, surgery, or supplemental oxygen. These options can also help you improve your breathing and sleep quality.

Myth: Sleep apnea cannot be cured.

Reality: Sleep apnea can be treated and managed, and in some cases, cured, with proper diagnosis and treatment. For example, if enlarged tonsils or adenoids cause sleep apnea, surgery can remove them and fix them; or if fat is the cause of sleep apnea, then decreasing weight can reduce or eliminate the symptoms. However, some cases of sleep apnea may not be curable and require lifelong treatment and management.
