Sleep problems are among the most common health complaints in the United States. According to the Centers for Disease Control and Prevention (CDC), nearly one in three adults doesn’t get enough sleep. Two of the most frequent culprits are sleep apnea and insomnia, distinct disorders that require different types of care.
At Prima CARE, our board-certified sleep medicine specialists in Fall River, MA, diagnose and treat a full range of sleep disorders, helping patients restore healthy sleep and improve their quality of life. Through sleep studies, advanced treatment options, and ongoing care, we provide the expertise and support needed to get to the root of sleep issues.
If you’re unsure whether your sleep struggles stem from insomnia, sleep apnea, or both, understanding their differences is the first step toward better rest and better health.
Understanding Sleep Apnea vs. Insomnia
While both conditions cause poor sleep, their origins are very different.
- Sleep apnea is a breathing-related disorder that causes pauses or interruptions in breathing during sleep.
- Insomnia, on the other hand, is a sleep initiation or maintenance problem, where a person has trouble falling asleep or staying asleep despite having the opportunity to rest.
Recognizing the difference between sleep apnea and insomnia helps patients get proper evaluation and treatment instead of relying on short-term remedies.
Key Symptoms That Differentiate Sleep Apnea from Insomnia
Sleep Apnea Symptoms
Sleep apnea often goes unnoticed because it occurs while you’re asleep. Common signs include:
- Loud, chronic snoring
- Pauses in breathing or gasping for air during sleep
- Morning headaches or dry mouth
- Daytime fatigue or irritability
- Poor concentration or memory problems
Sleep apnea symptoms in women may present differently. Instead of loud snoring, women may experience more subtle signs such as insomnia-like wakefulness, fatigue, and anxiety during the day. These differences often lead to underdiagnosis.
Insomnia Symptoms
Insomnia feels more conscious; you know you can’t sleep. Common signs include:
- Difficulty falling asleep or staying asleep
- Waking up too early and being unable to go back to sleep
- Feeling unrefreshed in the morning
- Daytime drowsiness, low energy, or mood swings
- Anxiety about not sleeping
While insomnia can sometimes be a symptom of sleep apnea, it is usually linked to stress, anxiety, caffeine intake, irregular sleep habits, or underlying medical conditions.
Common Causes of Each Sleep Disorder
What Causes Sleep Apnea?
Sleep apnea is usually classified as:
- Obstructive Sleep Apnea (OSA): The most common type, caused by airway blockage due to relaxed throat muscles.
- Central Sleep Apnea: A brain signal issue that prevents the body from breathing properly during sleep.
- Complex Sleep Apnea: A combination of both types.
Risk factors include obesity, family history, smoking, nasal congestion, and certain medical conditions like hypertension or diabetes.
What Causes Insomnia?
Insomnia can develop suddenly or gradually and may be short-term or chronic. Common causes include:
- Stress and mental health conditions, such as anxiety or depression
- Poor sleep habits or inconsistent schedules
- Excess caffeine, alcohol, or nicotine use
- Medications or hormonal changes
- Chronic pain or illness
Some individuals experience both; sleep apnea can disrupt rest and lead to insomnia-like symptoms, creating a cycle of exhaustion.
Can Insomnia Cause Sleep Apnea?
While insomnia itself doesn’t directly cause sleep apnea, the two conditions can coexist. People who struggle to fall asleep may also experience undiagnosed sleep apnea that prevents deep, restorative sleep. Treating one without addressing the other can make symptoms persist.
If you regularly feel tired even after sleeping or experience both breathing disruptions and difficulty sleeping, it’s important to undergo a comprehensive sleep evaluation.
Treatment Options for Sleep Apnea vs. Insomnia
Sleep Apnea Treatment
Sleep apnea is highly treatable once diagnosed. At Prima CARE’s Sleep Disorders Center, treatment plans are customized based on the type and severity of apnea. Options include:
- CPAP (Continuous Positive Airway Pressure) therapy: Keeps airways open using gentle air pressure.
- Oral appliance therapy: A comfortable, dentist-fitted device that repositions the jaw to improve airflow—ideal for mild to moderate cases.
- Lifestyle modifications: Weight management, positional therapy, and avoiding alcohol or sedatives before bed.
Insomnia Treatment
Insomnia treatment focuses on identifying and correcting underlying causes. Effective strategies include:
- Cognitive Behavioral Therapy for Insomnia (CBT-I): A structured program that helps change negative sleep thoughts and habits.
- Sleep hygiene education: Consistent sleep schedules, minimizing screen time, and creating a calm bedtime routine.
- Relaxation techniques: Deep breathing, mindfulness, or meditation to reduce nighttime stress.
- Medication (if needed): Short-term sleep aids may be prescribed, but are typically a last resort.
At Prima CARE, our sleep specialists work closely with behavioral health providers and primary care physicians to address both physical and psychological contributors to poor sleep.
How Untreated Sleep Disorders Impact Health
Chronic sleep loss doesn’t just affect how you feel; it affects nearly every organ system. Untreated sleep apnea can increase the risk of heart disease, high blood pressure, diabetes, and stroke, while persistent insomnia can contribute to anxiety, depression, weakened immunity, and weight gain.
Sleep is a cornerstone of overall health. By addressing these issues early, patients can dramatically improve their long-term wellness and quality of life.

Frequently Asked Questions
What’s the difference between sleep apnea and insomnia?
Sleep apnea causes repeated breathing interruptions during sleep, while insomnia involves difficulty falling asleep, staying asleep, or waking too early.
Can insomnia cause sleep apnea?
Not directly, but both can occur together. When this happens, poor rest and fatigue often worsen until both conditions are properly treated.
What are common sleep apnea symptoms in women?
Women may notice subtler signs such as fatigue, insomnia, mood changes, or morning headaches rather than loud snoring or gasping.
How is sleep apnea treated?
Treatment depends on the cause and severity. Options may include airway-support devices, oral appliances, or lifestyle changes to improve breathing and sleep quality. A sleep specialist can help determine the most effective plan.
When should I see a doctor for sleep problems?
If you have persistent sleep difficulties, loud snoring, or fatigue that lasts longer than two weeks, it’s best to schedule a sleep evaluation to identify the cause.
