Beyond CPAP: Uncovering the Roots of Sleep Apnea
Is CPAP Restoring Health—or Simply Managing the Symptoms?
Sleep apnea affects millions of people worldwide, many of whom rely on CPAP machines each night to maintain steady breathing and achieve deeper rest. If that’s you, maybe you’ve noticed improvements in energy since starting CPAP therapy. Or perhaps it’s simply become part of your nightly routine… even if you still wake up tired, congested, or foggy.
Here’s the question few people stop to consider:
Is CPAP addressing the root causes of sleep apnea, or is it simply managing the symptoms?
In this article, we’ll explore what sleep apnea really is, how CPAP therapy works, and why some researchers are raising questions about whether CPAP may interfere with the body’s natural healing processes. As always, we share this perspective with compassion and respect. Our goal is not judgment, but rather to uncover the deeper drivers of sleep apnea so that true healing becomes possible.
What Is Sleep Apnea? Symptoms, Types, and Risks
Sleep apnea is a condition in which breathing repeatedly stops and starts during sleep, interrupting the body’s natural repair and recovery. There are three main types:
Obstructive Sleep Apnea (OSA): The airway collapses or becomes physically blocked, preventing airflow
Central Sleep Apnea (CSA): The brain fails to send proper signals to the muscles that control breathing
Complex (Mixed) Sleep Apnea: A combination of both obstructive and central causes
In obstructive sleep apnea (OSA), the airway collapses or becomes blocked during sleep, disrupting airflow and oxygen levels.
Common symptoms include loud snoring, gasping or choking during sleep, unrefreshing sleep, morning headaches, daytime fatigue, brain fog, and—in some cases—elevated blood pressure, cardiovascular strain, or mood disturbances.
But here’s the key point from a functional medicine perspective:
Sleep apnea itself isn’t the root cause—it’s a downstream symptom of deeper physiological dysfunction.
The Real Drivers of Sleep Apnea
Sleep apnea is often described as a mechanical issue—extra tissue in the airway, a weak tongue, or poor sleep posture. But these are surface-level expressions. The deeper drivers of sleep apnea begin at the cellular level, inside your mitochondria, the tiny energy factories that fuel every cell.
A 3D-rendered mitochondrion: These cellular powerhouses are responsible for generating the energy that powers your breathing rhythm.
How Mitochondrial Energy Fuels the Brainstem’s Breathing Signals
Your brainstem (especially the pre-Bötzinger complex) acts as the pacemaker for your breath during sleep. It constantly monitors carbon dioxide (CO₂) levels and signals your diaphragm to contract or relax. This process depends on ATP, the energy currency made by your mitochondria.
When mitochondrial function is impaired:
The brainstem becomes sluggish
Breathing rhythm breaks down
Apnea occurs—not just from airway collapse, but because the brain fails to send the signal
How Weak Cellular Energy Leads to Collapsed Airways
Your tongue, throat, and diaphragm all rely on mitochondrial energy to maintain muscle tone and responsiveness. During sleep, when muscles naturally relax, mitochondria help keep them just firm enough to prevent collapse.
When mitochondria are underpowered:
Airway muscles lose tone
The throat collapses during deep sleep
Oxygen levels drop, triggering gasping or choking awakenings
Think of it like this:
A fully charged battery (healthy mitochondria) powers your airway muscles to stay open
A drained battery (dysfunctional mitochondria) lets everything go slack
The CO₂ Signalling Breakdown: Why Oxygen Isn’t the Whole Story
Here’s a key insight: sleep apnea isn’t just about oxygen, it’s about carbon dioxide.
Your body takes its next breath not because oxygen is low, but because CO₂ has risen enough to trigger the brain to act.
When mitochondria shift from efficient energy production (oxidative phosphorylation) to a backup mode (glycolysis), the result is:
Less CO₂ being produced
Weaker breathing signals sent to the brain
Longer pauses between breaths
Oxygen paradoxically rising, but without proper respiration
This breakdown in cellular communication helps explain why some people don’t improve with CPAP. The issue isn’t purely mechanical—it’s metabolic and neurological.

Circadian Rhythm Disruption & Sleep Apnea
Mitochondria don’t just make energy, they keep time. They rely on circadian cues like sunlight, temperature changes, and melatonin to function optimally. Getting morning sunlight exposure is one of the simplest ways to anchor your sleep cycle (read more on the power of sunlight here).
If you:
Miss morning sunlight
Stay up late under blue light
Sleep surrounded by electromagnetic fields (EMFs)
…your mitochondria lose their rhythm. And when that happens, the autonomic nervous system and diaphragm fall out of sync, raising your risk for sleep apnea.
CPAP for Sleep Apnea: What It Helps and What It Misses
CPAP (Continuous Positive Airway Pressure) remains the gold-standard treatment for moderate to severe sleep apnea. The machine delivers a steady stream of pressurized air to keep the airway open during sleep.
CPAP gives short‑term relief but doesn’t always restore sleep rhythm.
Short-Term Benefits of CPAP
Fewer apneic episodes
Less snoring
A sense of deeper, more restful sleep
For many, CPAP provides quick symptom relief. But symptom relief is not the same as root-cause healing. Long-term use may carry unintended consequences, especially if underlying dysfunction is left unaddressed.
Potential Risks & Long-Term Limitations of CPAP
Over-Oxygenation and Oxidative Stress
Mitochondria are designed to function within precise oxygen ranges. Too much oxygen without proper electron flow leads to inflammation and free radical damage—a form of oxidative stress that disrupts energy production. We’ve written more about supporting mitochondria and reducing this stress in our Spring Mitochondrial Recharge article.Disrupted Nitric Oxide (NO) Production
CPAP often encourages mouth breathing, bypassing the nasal passages where nitric oxide is produced. Nitric oxide plays a critical role in vascular health, immune defense, and keeping blood vessels open and resilient.Cranial Nerve and Vagal Tone Disruption
Continuous mask pressure across the face may subtly affect cranial nerve signalling, including the vagus nerve which regulates digestion, heart rhythm, and the body’s rest-and-repair state.EMF Exposure and Melatonin Suppression
CPAP machines emit low-level electromagnetic fields (EMFs). Some research suggests EMFs may interfere with mitochondrial function and reduce melatonin production, a hormone essential for circadian rhythm and sleep quality.A False Sense of Security
Feeling “better” with CPAP doesn’t always mean the body is healing. Inflammation, circadian disruption, and mitochondrial stress may continue beneath the surface leaving the root causes unresolved.

The Great Oxygen Paradox
“If oxygen were always helpful, why do mitochondria have systems to restrict it?”
We’ve been taught that oxygen is always beneficial. But oxygen, while essential, is also a potent oxidizer—it can heal, and it can harm.
Neurosurgeon and quantum biologist Dr. Jack Kruse calls this the “Great Oxygen Paradox.”
Here’s the nuance:
Your mitochondria use oxygen at the end of the electron transport chain to produce ATP (the body’s usable energy.) But when this chain is disrupted (by poor circadian rhythm cues, chronic inflammation, or mitochondrial dysfunction) oxygen builds up without being efficiently used.
The result?
Oxidative stress
Accelerated cellular aging
Depleted energy
This is the paradox: more oxygen doesn’t always mean more energy. It also helps explain why some patients feel immediate relief with CPAP… yet continue to wake up tired, inflamed, or foggy.
Natural & Functional Therapies to Address Sleep Apnea Root Causes
Instead of forcing the body to breathe mechanically, what if we restored its natural rhythm? Functional medicine focuses on building resilience at the cellular and neurological level so the body remembers how to breathe on its own.
Here are key strategies that support mitochondrial health, circadian alignment, and airway tone:
Nasal Breathing Retraining
Techniques like Buteyko breathing, mouth taping, and even humming help retrain the nervous system to default to nasal breathing. This improves oxygen efficiency and increases nitric oxide production.
Cold Exposure & Grounding
Simple practices like cold showers or barefoot time outdoors help regulate vagal tone, reduce inflammation, and improve cellular oxygen sensing.
Myofunctional Airway Exercises
Targeted exercises for the tongue, jaw, and airway muscles improve muscle tone and prevent collapse during sleep, reducing obstructive events without relying solely on a machine.
Morning Sunlight
Early exposure to natural light anchors circadian rhythm, helping restore healthy sleep architecture and natural breathing patterns at night.
Mineral Repletion
Key nutrients such as retinol (vitamin A), magnesium, copper, and B vitamins are essential for mitochondrial energy production and repair. Without them, breathing regulation falters.
Red & Infrared Light Therapy
Targeted light therapy recharges mitochondrial function and supports melatonin production, which improves sleep depth and circadian balance.
Sleep Is a Mitochondrial Process
If you’re using CPAP, this isn’t about blame or fear. CPAP may have been a lifeline—and for many, it truly is. But surviving is not the same as thriving.
Sleep apnea is your mitochondria’s way of saying: “I’m tired.”
The good news? Your body is designed to heal when given the right inputs—light, breath, minerals, and rhythm.
You don’t just need more oxygen. You need more energy. And that energy starts at the cellular level.
FAQ: Sleep Apnea & CPAP
-
CPAP reduces symptoms by keeping your airway open, but it doesn’t address the underlying causes like mitochondrial dysfunction, circadian rhythm disruption, or airway muscle tone. Looking deeper means aiming for healing, not just management.
-
Yes. Many therapies—such as nasal breathing retraining, airway exercises, mineral support, and circadian light exposure—can be added alongside CPAP. Over time, these strategies may reduce your dependence on the machine while improving overall health.
-
Absolutely. Because sleep apnea disrupts oxygen balance, mitochondrial energy, and circadian rhythm, it often shows up as fatigue, weight challenges, brain fog, or even mood disturbances. Treating the root cause can improve much more than sleep.
