The primary reason you might "forget" to breathe while awake is that your brain isn't automatically regulating your breathing as it should. In other words, the signals telling your body to breathe aren't being consistently sent. This is often associated with a condition called Congenital Central Hypoventilation Syndrome (CCHS), though other causes can contribute.
Understanding Automatic Breathing
Normally, breathing is an involuntary process controlled by the autonomic nervous system. This means you don't consciously have to think about each breath you take; your brain takes care of it for you.
Congenital Central Hypoventilation Syndrome (CCHS)
- What it is: CCHS is a rare, lifelong condition where the autonomic nervous system fails to properly regulate breathing.
- The Brain's Role: In CCHS, the brain "forgets" to send signals to the respiratory muscles, instructing them to contract and expand the lungs.
- Impact: This can lead to shallow breathing or even periods of apnea (stopping breathing) while awake and especially during sleep.
- Genetic Component: CCHS often has a genetic basis.
Other Potential Causes
While CCHS is a primary consideration, other factors can sometimes contribute to irregular or shallow breathing, making it feel like you're forgetting to breathe:
- Anxiety: Anxiety can lead to hyperventilation (rapid, shallow breathing) or breath-holding, creating a sensation of air hunger.
- Sleep Apnea: Although primarily a sleep disorder, untreated sleep apnea can disrupt breathing patterns even when awake.
- Certain Medications: Some medications can suppress the respiratory drive, making breathing less automatic.
- Neurological Conditions: Conditions affecting the brainstem can impact respiratory control.
- Obesity Hypoventilation Syndrome (OHS): Excess weight can impair lung function and lead to shallow breathing.
What To Do If You Suspect You're Forgetting to Breathe
- Consult a Doctor: This is crucial. Describe your symptoms in detail, including when you notice the breathing irregularities and any other associated symptoms (dizziness, fatigue, headaches).
- Pulmonary Function Tests: Your doctor may order tests to assess your lung function and breathing patterns.
- Sleep Study: A sleep study can help rule out sleep apnea.
- Neurological Evaluation: If other causes are ruled out, a neurological evaluation may be necessary to check for underlying neurological conditions.
In Summary
"Forgetting" to breathe while awake is a serious symptom that requires medical evaluation. While CCHS is a notable cause where the brain fails to send proper breathing signals, other conditions like anxiety, sleep apnea, or certain medications could be contributing factors. Prompt diagnosis and treatment are essential for managing the condition and ensuring adequate oxygen intake.
