Sleep apnea and insomnia are both sleep disorders that some believe are mutually exclusive or that the presence of one negates the other. However, the reality is that they can, and often, do coexist.
At Bedford Dental Group, we have a track record of providing comprehensive dental care, which extends to treatments and advice related to sleep disorders like sleep apnea. Our expertise is backed by the use of advanced tools and techniques to identify sleep-related issues often evident in dental health.
In this article, we will give clarity on how sleep apnea can contribute to insomnia and a comprehensive understanding of how these two conditions interact. We aim to prompt readers to take proactive steps towards improving their sleep health and overall quality of life after reading this article.
What is Sleep Apnea?

Before going ahead to examine the relationship between insomnia and sleep apnea, let’s look at them individually, starting with sleep apnea.
Sleep apnea is a sleep disorder where one experiences repeated interruptions in breathing during sleep. These interruptions are called apneas. They happen when the airway is partially or completely blocked. This disorder can also happen when the brain fails to send signals to the breathing muscles.
When any of these situations happens, breathing is paused, and it can last from a few seconds to minutes. Now, imagine this happening repeatedly throughout the night.
There are three types of sleep apnea:
- Obstructive Sleep Apnea (OSA): It is the most common type of sleep apnea. It happens when the soft tissue in the back of the throat collapses and closes during sleep. This leads to a physical blockage of the airway.
- Central Sleep Apnea (CSA): This occurs when the brain fails to send signals to the muscles that control breathing. Unlike obstructive sleep apnea, central sleep apnea is not caused by a physical blockage of the airway.
- Complex Sleep Apnea: It is also called mixed sleep apnea. It is a combination of both obstructive and central sleep apnea. It starts typically as OSA and evolves into CSA during treatment.
Loud snoring, abrupt awakenings, fatigue, and morning headaches are some common symptoms of sleep apnea. Other symptoms could be mood change, high blood pressure, difficulty in concentration, etc.
Risk factors for developing sleep apnea include obesity, smoking, high blood pressure, hypertension, etc. Studies show that men are at more risk when it comes to this sleep disorder. Age also comes in as a factor as older adults are more at risk.
It is important to note that not everyone who snores has sleep apnea, and not everyone with sleep apnea smores. That is why making an accurate diagnosis is important.
What is Insomnia?

Now, let’s break down the concept of insomnia. Compared to sleep apnea, insomnia is a more common sleep disorder.
It is a condition characterized by difficulty falling asleep or staying asleep. Insomnia patients usually do not get enough rest, and it affects their ability to function during the day.
They could experience decreased performance in everyday activities, fatigue, mood disturbances, etc. A case of insomnia is more persistent and often affects a person’s quality of life significantly.
Some types of insomnia are:
- Acute Insomnia: It is also known as short-term insomnia. It is typically triggered by stress or a traumatic event. It lasts for a few days to a few weeks.
- Chronic Insomnia: This is long-term insomnia. It occurs at least three nights per week for three months or longer. It can be caused by a variety of factors including chronic stress, pain, or medical conditions.
- Comorbid Insomnia: It occurs alongside another condition, either psychiatric (like depression or anxiety) or medical (such as arthritis or back pain) which either contributes to or exacerbates the insomnia.
- Onset Insomnia: It is a case where one experiences difficulty in falling asleep at the beginning of the night, often due to stress or psychological factors.
- Maintenance Insomnia: It is inability to stay asleep, or waking up too early and not being able to return to sleep. This type of insomnia is often related to underlying health issues or sleep disorders.
Insomnia symptoms can include difficulty falling asleep, staying asleep, waking up during the night, waking up too early, not feeling rested after a night’s sleep, sleep deprivation, excessive daytime sleepiness, etc. Patients with insomnia can also experience irritability, depression, or anxiety.
Causes of insomnia are varied and can include stress, travel, or work schedule. It can also be due to mental health disorders like anxiety and depression. It can also be caused by medical conditions such as asthma, diabetes, or chronic pain.
Insomnia and Sleep Apnea: Cause and Effect Relationship

Now that we have established that insomnia and sleep apnea are both sleep disorders, it is also important to note that they can influence each other. Sleep apnea is typically characterized by repeated breathing interruptions that can lead to insomnia symptoms.
Sleep apnea usually leads to sleep-disordered breathing, becoming a potential cause of insomnia. Anyone with a sleep-related breathing disorder would agree that it results in poor sleep and limits the rest one can get. All these can cause insomnia.
These sleep disturbances often lead to daytime fatigue and difficulty concentrating once it becomes consistent.
Both sleep apnea and insomnia share common symptoms like daytime fatigue, mood disturbances, and cognitive impairment. This overlap can sometimes make it challenging to immediately distinguish one disorder from the other without a thorough evaluation.
When sleep apnea and insomnia coexist, diagnosing either condition becomes more complex. The overlapping symptoms can mask the underlying causes, leading to misdiagnosis or incomplete treatment. It requires a careful evaluation of sleep patterns, medical history, and lifestyle factors.
Healthcare professionals use various tools for diagnosis, including sleep diaries, questionnaires, physical examinations, and sleep studies like polysomnography. These methods help in identifying the specific characteristics of each disorder.
Bedford Dental Group adopts a comprehensive approach to diagnosing and treating sleep apnea. Understanding the intricate relationship between dental health and sleep disorders, we utilize a blend of dental expertise and sleep medicine treatments to address sleep apnea. Whether it’s CPAP machines, mandibular advancement devices, or lifestyle changes, our dentists can help patients chart the best course of treatment based on their individual needs and lifestyles.
Sleep Apnea Treatment Complications

Treating sleep apnea and insomnia as separate entities can lead to complications. The treatments for one condition may worsen the other.
For example, the use of Continuous Positive Airway Pressure (CPAP) machines can sometimes disturb sleep, potentially worsening insomnia. Conversely, some medications used for insomnia may relax the throat muscles, aggravating obstructive sleep apnea.
Additionally, focusing on only one condition may overlook or inadequately address the coexisting symptoms of the other, leading to incomplete treatment and persistent symptoms.
An effective approach to managing both insomnia and sleep apnea involves integrated treatment strategies that consider the interplay between these conditions. For those using CPAP therapy, ensure to use a comfortable and well-fitting mask. It helps to adjust pressure settings and minimizes discomfort during sleep. You can also consider alternative treatments like oral appliance therapy.
If medications are necessary for insomnia treatment, careful selection and monitoring is necessary. It helps to avoid worsening sleep apnea. Healthcare providers might opt for non-habit-forming medications and closely monitor their effects.
Life Expectancy with Sleep Apnea

When left untreated, severe sleep apnea can have significant long-term health implications that may affect life expectancy. Chronic sleep deprivation and intermittent oxygen deprivation due to sleep apnea can lead to various health issues.
The repeated episodes of low oxygen levels during sleep strain the cardiovascular system. This leads to an increased risk of high blood pressure, heart disease, stroke, etc. Sleep apnea is also a contributing factor to obesity.
The combined effect of both insomnia and sleep apnea leads to a more pronounced impact on cardiovascular health, obesity, and mental well-being. Lifestyle factors play a crucial role in managing and potentially alleviating symptoms of sleep apnea and insomnia.
A balanced diet can help in weight management, which is crucial in reducing the severity of sleep apnea. Avoiding heavy meals, caffeine, and alcohol before bedtime can also improve sleep quality.
Regular physical activity can help reduce the severity of sleep apnea, aid in weight management, and improve sleep quality. Even moderate activities like walking can be beneficial.
High levels of stress can worsen both sleep apnea and insomnia. Techniques such as mindfulness, meditation, yoga, and deep breathing exercises can be effective in managing stress.
Treating Insomnia and Sleep Apnea
Insomnia and sleep apnea share a complex interrelationship. It’s clear that these two sleep disorders often intersect and impact one another.
The overlapping symptoms of these conditions underscore the importance of a professional diagnosis. Accurate diagnosis is crucial as it guides the appropriate and effective treatment strategies. For instance, while CPAP therapy is a standard treatment for sleep apnea, it might not be suitable for someone whose primary issue is insomnia. Similarly, medication used for insomnia might worsen sleep apnea symptoms if not carefully managed.
Comprehensive treatment is key. This involves not only addressing the specific sleep disorder but also considering any underlying factors or co-occurring conditions. Lifestyle modifications, such as diet and exercise, play a vital role in managing both conditions.
If you are experiencing either sleep apnea or insomnia symptoms, or if you suspect you might have both, seek professional medical advice. Remember, addressing these issues is not just about improving sleep — it’s about enhancing your overall health and quality of life.
