Tired All the Time? Your Breathing Could Be To Blame
Feeling Exhausted No Matter How Much You Rest?
You’re not alone—and the reason might surprise you.
If you constantly feel drained, mentally foggy, or wiped out after even light activity, your breathing patterns—not just your sleep or workload—could be playing a major role. According to new research published in Frontiers in Medicine, a large number of people with chronic fatigue syndrome (CFS) have undiagnosed breathing abnormalities that may be silently worsening their symptoms.
And the most concerning part? Many don’t even realize they’re breathing incorrectly.
What Is Chronic Fatigue Syndrome (CFS)?
Chronic fatigue syndrome is a complex condition marked by persistent, unexplained exhaustion, brain fog, poor concentration, and a worsening of symptoms after physical or mental effort—a phenomenon known as post-exertional malaise.
For years, patients have reported shortness of breath and dizziness, but the exact cause remained unclear. This new research sheds light on a hidden piece of the puzzle.
The Hidden Breathing Problem Researchers Found
Scientists studied 57 people with chronic fatigue syndrome and compared them with 25 healthy individuals of similar age and activity level. Participants underwent cardiopulmonary exercise testing over two days, during which their breathing patterns, oxygen use, heart rate, and blood pressure were closely monitored.
Key finding:
71% of people with chronic fatigue showed abnormal breathing patterns, compared to just a handful of healthy participants.
These abnormalities included:
- Dysfunctional breathing
- Hyperventilation
- Or a combination of both
Importantly, oxygen uptake (VO₂ max) was normal, meaning fatigue wasn’t due to poor oxygen delivery—but rather how breathing was being controlled.
What Is Dysfunctional Breathing?
Dysfunctional breathing isn’t always obvious and can happen even at rest. It may include:
- Breathing too fast or too deeply
- Frequent sighing
- Chest-dominant breathing instead of diaphragm use
- Poor coordination between chest and abdominal muscles
- Forceful exhalation using abdominal muscles
Because these patterns often develop subconsciously, many people are completely unaware they’re doing it.
Why This Makes Fatigue Worse
Both dysfunctional breathing and hyperventilation can trigger symptoms that closely mimic—or worsen—chronic fatigue, such as:
- Dizziness
- Brain fog
- Shortness of breath
- Heart palpitations
- Chest discomfort
- Anxiety
- Extreme tiredness
When these breathing issues occur together, symptoms often intensify—especially after exertion.
Researchers believe this may be linked to dysautonomia, a nervous system disorder common in CFS that affects heart rate, blood pressure, and breathing regulation.
The Dysautonomia Connection (Simple Explanation)
In many CFS patients, the autonomic nervous system doesn’t regulate bodily functions properly. This can lead to:
- Increased heart rate when standing
- Irregular breathing
- Over-breathing (hyperventilation)
- Rapid fatigue
In short, the body stays stuck in a low-level “stress response,” even when resting.
Can Breathing Be Retrained?
The encouraging news: yes, potentially.
While more studies are needed, researchers suggest that addressing breathing dysfunction could ease symptoms for some patients.
Possible supportive approaches include:
- Gentle yoga with breath awareness
- Low-impact activities like swimming
- Biofeedback using CO₂ monitoring
- Breathing retraining to encourage slower, shallower, controlled breaths
These techniques aim to restore natural breathing rhythm and reduce unnecessary over-breathing.
Why This Research Matters
For years, chronic fatigue patients have struggled with symptoms that felt invisible or unexplained. This study validates a real, measurable physiological issue that may finally open doors to new treatment strategies.
As Dr. Benjamin Natelson from Icahn School of Medicine notes, identifying these breathing abnormalities could lead to meaningful symptom relief—and a better quality of life.
The Bottom Line
If you’re constantly tired and nothing seems to help, it might be time to pay attention to how you breathe—not just how much you sleep. Hidden breathing dysfunction could be silently draining your energy.
Sometimes, healing starts with something as simple—and powerful—as a breath.
