Chronic Insomnia: When to Get a Sleep Test
Chronic insomnia lasting three or more months is not simply a stress response or a bad habit. It may signal an underlying sleep disorder, including sleep-disordered breathing, that a home sleep test can identify. If you have struggled with sleep for months and nothing has worked, a physician evaluation is the medically appropriate next step.

You have tried everything. Earlier bedtimes. No screens after 9. Melatonin. Still, you cannot sleep. Chronic insomnia affects your concentration, your mood, and your physical health. And it rarely resolves on its own when there is an underlying cause driving it.
Dr. Avinesh Bhar, board-certified sleep physician at Sliiip.com, sees this pattern regularly. Patients spend years managing insomnia symptoms without ever identifying what is causing them. The result is months or years of disrupted sleep and declining health.

Myth vs. Reality
Common Belief | Clinical Reality |
Insomnia is just stress or anxiety | Chronic insomnia lasting more than three months often has a physiological component that behavioral changes alone will not resolve |
Sleep tests are only for people who snore | Sleep-disordered breathing frequently occurs without snoring, especially in women, and is commonly missed in insomnia patients |
Insomnia is not serious enough to see a doctor | Persistent insomnia is associated with increased cardiovascular risk, impaired immune function, and mood disorders |
If I could just relax more, I would sleep | Nocturnal arousal from airway obstruction cannot be resolved through relaxation techniques alone |
What Is Chronic Insomnia?
Chronic insomnia is defined as difficulty falling asleep, staying asleep, or waking too early at least three nights per week for a minimum of three months. It must also cause functional impairment during the day.
Acute insomnia is short-term and typically tied to a specific stressor. Chronic insomnia does not follow that pattern. It persists regardless of what is happening in your life.
Why Chronic Insomnia Requires More Than Lifestyle Changes
Behavioral adjustments help mild sleep difficulties. They do not always address the root cause. When insomnia is chronic, something physiological is often involved.
Sleep-disordered breathing is one of the most common and most overlooked causes. Partial airway obstruction during sleep creates micro-arousals. You may not snore. You may not even know you are waking. But your brain is registering each disruption and preventing you from reaching restorative sleep.
Other physiological contributors include restless legs syndrome, circadian rhythm dysfunction, and neurological hyperarousal. These require clinical evaluation, not just habit changes.
When to Get a Sleep Test for Insomnia
A sleep evaluation is appropriate when insomnia has persisted for three or more months, has not responded to basic sleep hygiene measures, or is accompanied by daytime fatigue, difficulty concentrating, or mood changes.
A home sleep test can be completed in your own bed without a lab visit. Sliiip uses FDA-approved SleepImage and WatchPAT devices. A board-certified sleep physician reviews your results and provides a clinical interpretation within days.
Is It Insomnia or Something Else?
Many people living with undiagnosed sleep disorders believe they simply have insomnia. The symptoms overlap significantly.
Difficulty falling asleep can reflect hyperarousal from disordered breathing. Waking repeatedly at night may be a physiological response to oxygen disruption. Waking unrefreshed is a hallmark sign that sleep architecture is fragmented.
A physician evaluation is the only reliable way to distinguish primary insomnia from insomnia caused by an underlying condition.
The Role of CBT-I in Insomnia Treatment
Cognitive Behavioral Therapy for Insomnia (CBT-I) is the first-line behavioral approach for chronic insomnia. It addresses the thought patterns and behaviors that perpetuate sleeplessness.
CBT-I is effective. But it works best when physiological causes have been ruled out first. Applying CBT-I to insomnia driven by untreated sleep apnea typically yields incomplete results.
Expert Q&A
Q: How do I know if I need a sleep test or just better sleep habits?
If your insomnia has persisted for more than three months and has not responded to basic interventions, a sleep evaluation is medically warranted. Sleep habits matter, but they do not resolve physiological sleep disorders. A home sleep test provides objective data that no behavioral checklist can replicate.

Q: Can chronic insomnia be a sign of sleep apnea?
Yes. A significant percentage of patients with chronic insomnia have undiagnosed sleep-disordered breathing. The connection is frequently missed because these patients do not present with classic snoring. Airway obstruction causes nocturnal arousals the patient interprets as insomnia.

Watch: Should I Do a Sleep Study?
Lifestyle Factors That Affect Chronic Insomnia
- Maintain a consistent wake time seven days per week
- Reserve the bed for sleep only to strengthen the mental association between bed and rest
- Limit caffeine after noon
- Reduce alcohol consumption, which fragments sleep in the second half of the night
- Keep your bedroom below 68 degrees Fahrenheit
- Avoid daytime napping longer than 20 minutes
Lifestyle changes are a useful foundation. They rarely resolve chronic insomnia when an underlying sleep disorder is present.

Frequently Asked Questions
How long does insomnia have to last before it is considered chronic?
Chronic insomnia is defined as sleep difficulty at least three nights per week for three or more months. If this has been your pattern for longer than three months, a clinical evaluation is appropriate.
Can I get a sleep test without seeing a doctor in person?
Yes. Sliiip is a telemedicine sleep medicine practice. You consult with a board-certified sleep physician virtually. If a home sleep test is indicated, the device ships to your home.
What does a home sleep test detect?
A home sleep test measures oxygen levels, breathing patterns, airflow, and physiological signals during sleep. Sliiip uses FDA-approved SleepImage and WatchPAT devices reviewed by board-certified physicians.
Does insurance cover a home sleep test for insomnia?
Sliiip accepts most major insurance plans, Medicare, and Tricare. A Sliiip physician can help determine what coverage may apply in your case.
Is CBT-I effective for chronic insomnia?
CBT-I is the first-line behavioral approach for chronic insomnia and is supported by extensive clinical evidence. It is most effective when underlying physiological causes have been evaluated first.
Can insomnia cause physical health problems?
Chronic insomnia is associated with elevated cardiovascular risk, impaired immune function, metabolic dysregulation, and worsening mood. Persistent insomnia warrants a medical evaluation.
What is the difference between primary and secondary insomnia?
Primary insomnia occurs independently of other conditions. Secondary insomnia is driven by an underlying condition such as sleep-disordered breathing. A physician evaluation is the most reliable way to distinguish between the two.
Does sleep apnea cause insomnia?
Sleep-disordered breathing can present as insomnia, particularly in women and in patients without classic snoring. This is frequently misdiagnosed without a formal sleep evaluation.
