What causes a sensation of suffocation during sleep?

In general, a sensation of suffocation during sleep may be related to improper sleeping posture, being overweight or obese, anxiety and stress, bronchial asthma, obstructive sleep apnea hypopnea syndrome, and other factors. If discomfort occurs, it is recommended to seek medical attention promptly. A detailed analysis is as follows:

1. Improper Sleeping Posture

When sleeping in the supine position, the base of the tongue tends to fall backward, compressing the airway entrance and causing breathing difficulties, which may lead to a feeling of suffocation. It is recommended to try sleeping on your side, and use pillows to support the upper body to reduce posterior displacement of the tongue.

2. Being Overweight or Obese

Excessive body fat may cause laxity and prolapse of soft tissues in the upper respiratory tract, leading to airway narrowing during sleep and resulting in a sensation of suffocation. Losing weight through a balanced diet and moderate exercise can help improve airway patency.

3. Anxiety and Stress

Negative emotions such as anxiety and excessive stress may trigger sympathetic nervous system activation, increasing respiratory rate and causing hyperventilation, thereby inducing a sensation of suffocation during sleep. Learning relaxation techniques such as deep breathing, meditation, and yoga may help alleviate anxiety.

4. Bronchial Asthma

Bronchial asthma is often associated with genetic factors, infections, medications, and others. Patients may experience increased vagal nerve activity and heightened airway reactivity at night, leading to symptoms such as wheezing and a sensation of suffocation during sleep, often accompanied by coughing and sputum production. Treatment may include medications such as budesonide inhalation aerosol, montelukast sodium tablets, and salmeterol fluticasone propionate inhalation powder, used as directed by a physician.

5. Obstructive Sleep Apnea Hypopnea Syndrome

This condition is commonly caused by factors such as nasal turbinate hypertrophy, tonsillar hypertrophy, and posterior displacement of the tongue base, resulting in upper airway narrowing or collapse and causing the aforementioned symptoms. Additional symptoms often include snoring and daytime sleepiness. Medications such as aminophylline tablets, atorvastatin calcium tablets, and medroxyprogesterone acetate tablets may be used under medical guidance for treatment.

During sleep, ensure good ventilation in the bedroom, maintain suitable temperature and humidity, and avoid consuming stimulants such as alcohol, tobacco, and caffeine, all of which can help improve sleep quality.
