70 million Americans have chronic sleep disorders — but only a fraction ever get properly diagnosed. Many conditions that masquerade as “I just don’t sleep well” have specific, treatable causes. Here’s what chiropractors and sleep specialists want you to know.
The Most Common Sleep Disorders
| Disorder | Prevalence | Key Symptom | Primary Treatment |
|---|---|---|---|
| Insomnia | 30–35% adults | Can’t fall/stay asleep | CBT-I, sleep hygiene, Rx |
| Sleep Apnea | ~30 million | Breathing stops repeatedly | CPAP, positional therapy |
| Restless Leg Syndrome | 7–10% adults | Urge to move legs at night | Iron supplementation, Rx |
| Circadian Rhythm Disorder | ~3% adults | Sleep at wrong times | Light therapy, melatonin |
| Narcolepsy | ~200,000 | Sudden sleep attacks | Stimulants, lifestyle |
Insomnia — The Most Common Sleep Disorder
Insomnia is defined as difficulty initiating or maintaining sleep, or early morning awakening with inability to return to sleep — occurring at least 3 nights per week for at least 3 months (chronic insomnia). It’s the most prevalent sleep disorder and also the most misunderstood.
Two Types of Insomnia
Primary insomnia has no identifiable underlying cause — it’s a condition in itself, typically driven by hyperarousal (the nervous system remaining in a heightened state). Secondary insomnia is caused by another condition: pain, anxiety, depression, medications, or environmental factors. For back and neck pain sufferers, secondary insomnia from pain is extremely common and significantly undertreated.
Evidence-Based Treatments for Insomnia
- CBT-I (Cognitive Behavioral Therapy for Insomnia): The gold-standard first-line treatment. More effective than sleeping pills long-term, with no side effects. Available via therapists, apps (Sleepio, SomRyst), and self-help books.
- Sleep restriction therapy: Counterintuitively, temporarily limiting time in bed consolidates sleep and rebuilds the brain’s sleep drive. Done under guidance of a sleep specialist.
- Stimulus control: Using the bed only for sleep (not reading, TV, phones) rebuilds the mental association between bed and sleep.
- Sleep hygiene: Consistent wake times, dark/cool environment, avoiding caffeine after noon, limiting alcohol (which fragments sleep).
Sleep Apnea — The Silent Epidemic
Obstructive sleep apnea (OSA) occurs when the muscles in the throat relax during sleep, causing the airway to partially or fully collapse. Each apnea event (breathing stoppage) typically lasts 10–30 seconds and can occur hundreds of times per night, fragmenting sleep and depriving the brain and organs of oxygen.
Symptoms of Undiagnosed Sleep Apnea
- Loud snoring (especially with gasping or choking sounds)
- Waking with headaches or dry mouth
- Excessive daytime sleepiness despite adequate time in bed
- Partner reports breathing pauses during sleep
- Difficulty concentrating, memory problems
- Mood changes, depression, irritability
Sleep Apnea and Sleep Position
Sleep position has a dramatic effect on apnea severity. Back sleeping is the worst position for apnea — it allows the tongue and soft palate to fall back and obstruct the airway. Side sleeping reduces apnea events by 50–70% in many patients with positional OSA. An adjustable bed base (elevated head 15–30°) is another highly effective positional intervention.
Restless Leg Syndrome
Restless Leg Syndrome (RLS) causes uncomfortable sensations in the legs — often described as crawling, aching, throbbing, or electrical sensations — that create an irresistible urge to move them. Symptoms are worse at rest and in the evening/night, making sleep onset extremely difficult.
RLS and Iron Deficiency
One of the most important (and frequently missed) connections: iron deficiency, even without full anemia, is strongly associated with RLS. Iron is required for dopamine synthesis in the brain, and dopamine dysregulation is central to RLS. A simple ferritin blood test (serum ferritin, not just hemoglobin) can identify this. Many patients see dramatic improvement in RLS symptoms when ferritin levels are raised above 50–75 ng/mL through supplementation.
How Chiropractic Care Improves Sleep
The connection between chiropractic care and sleep quality is more direct than most people realize. Spinal misalignments can:
- Cause pain that disrupts sleep: The most obvious mechanism — if your back or neck hurts, you wake up when you move or when the pain threshold is exceeded.
- Activate the sympathetic nervous system: Spinal irritation can keep the nervous system in a heightened (fight-or-flight) state, elevating cortisol and making it physiologically harder to fall asleep.
- Affect sleep position: Pain from misalignments often forces patients into protective sleep positions that are suboptimal for their spine, compounding the problem.
A 2017 study published in the Journal of Manipulative and Physiological Therapeutics found that 50% of chiropractic patients reported improved sleep as a secondary benefit of treatment for musculoskeletal pain.

Is Pain Disrupting Your Sleep?
Chronic back and neck pain is one of the most common causes of secondary insomnia. A supportive mattress is often one of the most impactful changes you can make. See our chiropractor-approved picks.
Frequently Asked Questions
What is the most common sleep disorder?
Insomnia is the most common sleep disorder, affecting 30–35% of adults at some point. Chronic insomnia (occurring at least 3 nights per week for 3+ months) affects approximately 10% of adults. Sleep apnea is the second most common, affecting an estimated 30 million Americans — the majority undiagnosed.
Can a chiropractor help with sleep problems?
Yes — particularly when sleep problems are related to pain or nervous system dysregulation. Chiropractic adjustments that reduce spinal pain and nervous system irritation frequently produce improved sleep as a secondary benefit. Studies show up to 50% of chiropractic patients report better sleep quality after treatment. However, chiropractic is not a standalone treatment for primary sleep disorders like insomnia or sleep apnea, which require specialist evaluation.
How do I know if I have sleep apnea?
Common signs include loud snoring, waking with headaches or dry mouth, excessive daytime sleepiness, and a partner reporting that you stop breathing during sleep. The only definitive diagnosis is a sleep study (polysomnography). At-home sleep testing devices, now widely available through primary care physicians, have made diagnosis significantly more accessible. If you suspect sleep apnea, discuss it with your doctor.
