Here’s what many people don’t realize: chronic insomnia can exist on its own, or it can signal something else entirely. Obstructive sleep apnea, for instance, often masquerades as insomnia. What feels like an inability to sleep may actually be repeated breathing interruptions pulling you out of rest. That’s why accurate diagnosis matters—and why some people find relief only after pursuing proper sleep apnea treatment rather than standard insomnia therapies.
What Makes Insomnia “Chronic”?
Not all insomnia is the same. Acute insomnia is short-term—usually triggered by stress, travel, or a difficult life event. It typically resolves within days or weeks once the triggering situation passes.
Chronic insomnia is different. It persists for three months or longer, occurs at least three nights per week, and continues despite having adequate time and opportunity to sleep. The problem isn’t your schedule or environment. Something deeper is interfering with your ability to rest.
Doctors further classify chronic insomnia as either primary or secondary. Primary insomnia develops without an obvious underlying cause—the sleep difficulty is the main issue. Secondary insomnia, on the other hand, stems from something else: a medical problem, psychiatric disorder, medication side effect, or another sleep disorder entirely.
Getting this distinction right matters because treating secondary insomnia means targeting its root cause, not just the sleeplessness itself.
What Are the Most Common Signs of Chronic Insomnia?
Chronic insomnia shows up in predictable patterns. At night, you might experience:
- Lying awake for 30 minutes or more before falling asleep
- Waking multiple times throughout the night
- Waking far too early and being unable to drift back to sleep
- Sleep that feels shallow, fragmented, or unrefreshing
The daytime consequences are equally telling. People with chronic insomnia often report persistent fatigue despite spending enough time in bed. Concentration suffers. Memory becomes unreliable. Irritability, anxiety, and low mood become constant companions. Work performance declines. Relationships feel the strain.
For a formal diagnosis, these symptoms must cause significant distress or impair daily functioning. Occasional rough nights don’t qualify—but months of disrupted sleep that affect your life certainly do.
What Causes Chronic Insomnia in Most People?
So what creates chronic insomnia in the first place? Rarely does a single culprit act alone. Multiple factors typically converge to create and maintain the problem.
Psychological factors rank among the most common culprits. Stress, anxiety, and depression all disrupt sleep architecture. Perhaps more insidiously, many people develop learned sleep anxiety—worrying so much about not sleeping that the worry itself prevents rest.
Medical issues frequently contribute as well. Chronic pain makes comfortable sleep nearly impossible. Asthma, heartburn, and neurological problems interrupt rest. Hormonal shifts during menopause or thyroid imbalances alter sleep patterns significantly.
Lifestyle and environmental factors play a substantial role. Irregular sleep schedules confuse your body’s internal clock. Caffeine consumed after early afternoon, alcohol before bed, and nicotine use all fragment sleep. Blue light from screens suppresses melatonin production. An uncomfortable mattress or noisy environment makes quality rest difficult.
Certain medications can trigger or worsen insomnia, including some antidepressants, stimulants, corticosteroids, and blood pressure medications.
Finally, other sleep disorders—particularly obstructive sleep apnea and restless leg syndrome—often produce symptoms that look exactly like chronic insomnia.
How Are Chronic Insomnia and Sleep Apnea Connected?
This connection deserves special attention because it’s frequently overlooked.
COMISA (comorbid insomnia and sleep apnea) represents the most common combination of co-occurring sleep problems. The statistics are striking: approximately 30-50% of people with obstructive sleep apnea also report chronic insomnia symptoms. Conversely, up to 40% of those diagnosed with chronic insomnia have undiagnosed sleep apnea.
The relationship runs both ways. Sleep apnea causes repeated micro-awakenings throughout the night as breathing stops and restarts. You may never fully wake up, yet these interruptions fragment sleep and leave you feeling unrested—a sensation indistinguishable from insomnia. Meanwhile, chronic insomnia increases physiological arousal, which can potentially worsen apnea severity.
This overlap creates real problems for treatment. Standard insomnia approaches like sleep restriction can be problematic (even dangerous) if sleep apnea is actually driving the symptoms.
The health stakes are serious. Research from Flinders University found that people with both sleep apnea and insomnia face a 47% higher mortality risk compared to those without either disorder. They’re twice as likely to develop high blood pressure and 70% more likely to have cardiovascular disease.
If your insomnia continues despite lifestyle changes and behavioral interventions, a sleep study may reveal a breathing-related cause that standard treatments won’t touch.
Treatment Options That Actually Work
Once you know what you’re dealing with, effective treatment becomes possible. The approach depends on the type and underlying cause of your sleep difficulties.
Cognitive Behavioral Therapy for Insomnia (CBT-I)
Sleep medicine guidelines consistently recommend CBT-I as the first-line treatment for chronic insomnia. This structured program—typically lasting six to eight weeks—tackles the behavioral and thought patterns that keep poor sleep going.
CBT-I includes sleep restriction (limiting time in bed to match actual sleep time), stimulus control (rebuilding the bed-sleep association), cognitive restructuring (challenging unhelpful beliefs about sleep), and relaxation techniques. It can be delivered in person, through telehealth, or via validated digital programs.
Unlike sleeping pills, CBT-I targets the maintenance factors that sustain insomnia long after the original trigger has disappeared.
Sleep Hygiene Fundamentals
Basic sleep practices support any treatment approach:
- Maintain consistent wake and sleep times, including weekends
- Keep your bedroom cool, dark, and quiet
- Avoid caffeine after early afternoon and limit alcohol before bed
- Exercise regularly, but not within five hours of bedtime
- Create a wind-down routine that signals your body to prepare for rest
Medication Considerations
Sleep medications can provide short-term relief but carry meaningful drawbacks. Dependence develops with regular use. Effectiveness diminishes over time. Side effects can impair next-day functioning.
When medications are appropriate, they work best alongside behavioral approaches rather than as standalone solutions. Melatonin supplements, despite their popularity, lack strong evidence for treating chronic insomnia specifically.
Addressing Underlying Conditions
When a medical or psychiatric issue contributes to insomnia, treating that problem often improves sleep significantly.
This principle is especially relevant for sleep apnea. When breathing interruptions are fragmenting your rest, no amount of sleep hygiene or cognitive therapy will solve the problem. Treatments like CPAP or neurostimulation therapy can resolve both the breathing disorder and the insomnia symptoms simultaneously—because they address what’s actually happening during sleep.
How Do You Start Taking Sleep Problems Seriously?
Chronic insomnia affects energy, mood, health, and daily functioning—but it responds to treatment. Taking your sleep struggles seriously, recognizing that multiple factors may be involved, and pursuing proper evaluation can change everything.
If months of poor sleep have become your norm, they don’t have to stay that way. Effective solutions exist, and often the key is simply knowing where to look.
