Stopping breathing occurs due to airway obstruction, neurological issues, or sleep disorders disrupting normal respiratory function.
The Mechanics Behind Breathing and What Causes It to Stop
Breathing is an automatic process controlled by the brainstem, specifically the medulla oblongata and pons. These areas constantly monitor carbon dioxide and oxygen levels in the blood, adjusting the respiratory rate accordingly. When everything functions normally, air flows freely through the nose or mouth, down the trachea, into the lungs where oxygen enters the bloodstream, and carbon dioxide is expelled.
However, when breathing suddenly stops or pauses, it’s usually because something interrupts this smooth process. The causes can be broadly divided into mechanical obstructions in the airway, neurological malfunctions affecting respiratory control, or conditions that alter muscle function needed for breathing.
Understanding why you stop breathing requires looking at how these systems can fail. For instance, a blocked airway physically prevents air from reaching your lungs. On the other hand, neurological disorders might stop your brain from signaling your muscles to breathe properly. Each cause presents distinct symptoms and risks.
Common Causes of Breathing Cessation
Obstructive Causes
One of the most common reasons people stop breathing temporarily is airway obstruction. This can happen during sleep (obstructive sleep apnea), choking on food or foreign objects, or swelling from allergic reactions (anaphylaxis). In obstructive sleep apnea (OSA), throat muscles relax too much during sleep causing the airway to collapse partially or completely.
This leads to repeated episodes where breathing halts for 10 seconds or more multiple times an hour. The brain senses low oxygen levels and briefly wakes you up to reopen the airway. This cycle disrupts restful sleep and can cause daytime fatigue and other health issues.
Choking is an acute emergency where food or other objects block airflow suddenly. It requires immediate intervention like the Heimlich maneuver to clear the obstruction.
Neurological Causes
Breathing depends on signals sent from your brain to respiratory muscles like the diaphragm. If this communication breaks down due to stroke, traumatic brain injury, or diseases such as amyotrophic lateral sclerosis (ALS), breathing may stop involuntarily.
Central sleep apnea differs from obstructive types in that it’s caused by a failure of brain signals rather than physical blockage. The brain simply forgets or fails to send commands to breathe regularly during sleep.
Brainstem tumors or infections can also impair respiratory centers leading to irregular breathing patterns or apnea episodes.
Muscle and Nerve Disorders
The diaphragm and intercostal muscles are essential for lung expansion during inhalation. Conditions like muscular dystrophy or spinal cord injuries can weaken these muscles or sever nerve connections causing inadequate ventilation.
Without strong muscle contractions pulling air into lungs efficiently, oxygen levels drop rapidly leading to hypoxia if untreated.
Sleep Apnea: A Major Contributor to Stopping Breathing
Sleep apnea affects millions worldwide but often goes undiagnosed. It’s characterized by repetitive pauses in breathing during sleep lasting 10 seconds or longer with partial or complete blockage of airflow.
There are two main types:
- Obstructive Sleep Apnea (OSA): Caused by relaxation of throat muscles blocking airflow.
- Central Sleep Apnea (CSA): Caused by failure of brain respiratory centers.
Symptoms include loud snoring, gasping for air during sleep, excessive daytime tiredness, morning headaches, and difficulty concentrating. Untreated sleep apnea increases risks of hypertension, heart disease, stroke, diabetes, and even sudden death during sleep.
Doctors diagnose it through overnight polysomnography tests that record breathing patterns, oxygen levels, heart rate, and brain activity while sleeping.
Treatment varies depending on severity but often includes:
- Continuous positive airway pressure (CPAP) machines that keep airways open with steady airflow pressure.
- Oral appliances that reposition the jaw.
- Lifestyle changes such as weight loss and avoiding alcohol before bedtime.
- Surgical interventions in severe cases.
Neurological Disorders Impacting Breathing
Certain neurological conditions directly affect your ability to maintain regular breaths:
- Stroke: Damage to brain areas controlling respiration may cause irregular breathing patterns like Cheyne-Stokes respiration—a cycle of deep breaths followed by apnea.
- Amyotrophic Lateral Sclerosis (ALS): Progressive loss of motor neurons weakens respiratory muscles over time leading to respiratory failure.
- Brainstem Tumors: These can press on vital respiratory centers disrupting normal function.
- CNS Infections: Encephalitis or meningitis can inflame brain tissue affecting respiration control.
In these cases, mechanical ventilation support might be necessary when spontaneous breathing becomes inadequate.
The Role of Anxiety and Panic Attacks in Breathing Irregularities
Although not a direct cause of stopping breathing completely, anxiety disorders can trigger hyperventilation—rapid shallow breaths that disrupt normal oxygen-carbon dioxide balance in blood. This may cause sensations of breathlessness or choking but usually doesn’t result in full cessation of breath unless severe panic attacks induce temporary paralysis of chest muscles.
Understanding this distinction helps avoid unnecessary panic while addressing underlying psychological triggers effectively through therapy and medication if needed.
The Impact of Respiratory Diseases on Breathing Pauses
Chronic lung diseases such as chronic obstructive pulmonary disease (COPD), asthma attacks, pneumonia, and pulmonary embolism all interfere with normal airflow mechanics causing difficulty maintaining continuous breaths. Severe exacerbations may lead to hypoventilation where insufficient air reaches alveoli resulting in low oxygen saturation.
Patients with advanced lung disease often experience episodes where they feel unable to catch their breath fully—sometimes mistaken for “stopping breathing.” Medical intervention focuses on improving lung function with bronchodilators, steroids, oxygen therapy or even mechanical ventilation when necessary.
A Closer Look at Apnea Events: Duration & Frequency Table
| Type of Apnea Event | Duration Range (seconds) | Frequency per Hour (Average) |
|---|---|---|
| Mild Obstructive Sleep Apnea | 10 – 20 seconds | 5 – 15 events/hour |
| Moderate Obstructive Sleep Apnea | 10 – 30 seconds | 15 – 30 events/hour |
| Severe Obstructive Sleep Apnea | >30 seconds possible; up to 60 seconds reported | >30 events/hour; sometimes exceeding 60 events/hour |
| Central Sleep Apnea Events | 10 – 40 seconds typical; longer possible in rare cases | Varies widely; often fewer than obstructive types but significant impact when present |
This table outlines typical durations and frequencies seen clinically in different types of apnea events. Longer duration events carry higher risk due to prolonged oxygen deprivation leading to cardiovascular strain and cognitive impairment over time.
The Immediate Risks When You Stop Breathing Suddenly
Sudden cessation of breath triggers rapid drops in blood oxygen levels called hypoxemia while carbon dioxide builds up causing hypercapnia. These changes strain vital organs:
- The Brain: Oxygen deprivation damages neurons within minutes causing confusion, loss of consciousness or permanent injury if prolonged.
- The Heart: Hypoxia stresses cardiac tissue contributing to arrhythmias and increasing risk for heart attacks.
- The Lungs: Repeated apneas cause inflammation weakening lung tissue over time worsening overall function.
In emergencies such as choking or severe allergic reactions stopping breathing entirely without intervention leads quickly to death within minutes due to irreversible organ damage from lack of oxygen supply.
Treatment Approaches for Stopping Breathing Episodes
Managing episodes where you stop breathing depends entirely on underlying causes:
- If caused by obstruction:
Immediate clearing techniques include Heimlich maneuver for choking; epinephrine injections for allergic swelling; CPAP devices during sleep apnea episodes maintain airway patency continuously preventing collapse.
- If neurological:
Treatment targets underlying disease progression with medications controlling symptoms plus supportive care including ventilator assistance if necessary.
- If muscle weakness related:
Physical therapy aimed at strengthening respiratory muscles combined with mechanical ventilation support prolongs survival.
Lifestyle modifications such as weight management reduce severity especially in obstructive causes by decreasing fat deposits around upper airway structures improving airflow.
Lifestyle Factors That Influence Your Breathing Health Daily
Breathing quality reflects overall health status influenced heavily by daily habits:
- Avoid smoking which damages lung tissue irreversibly leading to chronic obstructive pulmonary disease increasing risk for apneas.
- Avoid excessive alcohol intake before bed since it relaxes throat muscles worsening obstructive apnea severity.
- Avoid sedatives unless prescribed carefully as they depress central nervous system reducing respiratory drive further risking central apneas.
Regular exercise improves cardiovascular fitness supporting efficient oxygen delivery while strengthening respiratory muscles reducing fatigue.
Maintaining a healthy weight alleviates pressure on diaphragm facilitating easier chest expansion.
Sleeping on one’s side rather than back prevents gravity-induced airway collapse common in supine positions.

Frequently Asked Questions
Why do I stop breathing during sleep?
Stopping breathing during sleep is often caused by obstructive sleep apnea, where throat muscles relax and block the airway. This leads to repeated pauses in breathing, disrupting sleep and lowering oxygen levels, which can cause fatigue and other health problems.
Why do I stop breathing when choking?
Choking occurs when food or a foreign object blocks your airway, preventing air from reaching your lungs. This sudden obstruction requires immediate action, such as the Heimlich maneuver, to clear the airway and restore normal breathing.
Why do I stop breathing due to neurological issues?
Neurological problems like stroke or brain injury can disrupt signals from the brain to respiratory muscles. When these signals fail, your body may stop sending commands to breathe, causing involuntary pauses or cessation of breathing.
Why do I stop breathing because of muscle function problems?
Certain conditions affect the muscles involved in breathing, such as the diaphragm. When muscle function is impaired by disease or injury, it can lead to difficulty maintaining normal respiration and cause you to stop breathing temporarily.
Why do I stop breathing even if my airway is clear?
If your airway is clear but you still stop breathing, it may be due to central sleep apnea or neurological disorders. These conditions affect the brain’s ability to regulate respiratory rhythm rather than a physical blockage of airflow.
