طبيبة تحذر: كتم العطس قد يؤدي إلى تلف الرئتين ومضاعفات خطيرة – أخبار حياة

Suppressing a sneeze may seem like a matter of social etiquette, but medical professionals warn that obstructing the body’s natural reflex can lead to significant physiological trauma. When you force a sneeze to stop—typically by pinching the nose and closing the mouth—the high-pressure air that would normally be expelled is redirected internally, potentially causing injuries ranging from ruptured eardrums to rare but serious damage to the lungs and throat.

As a physician, I often emphasize that sneezing is a vital protective mechanism designed to clear the upper respiratory tract of irritants, such as dust, pollen, or pathogens. According to the National Center for Biotechnology Information, a sneeze can generate air velocities exceeding 100 miles per hour. When this kinetic energy is trapped within the pharynx, the resulting pressure surge must dissipate somewhere, often finding the path of least resistance through the Eustachian tubes, the sinuses, or the esophagus.

Risks Associated with Suppressed Sneezes

The most immediate risks of holding in a sneeze involve the delicate structures of the head and neck. Otolaryngologists have documented cases where the sudden spike in pressure causes a perforation of the tympanic membrane, commonly known as a ruptured eardrum. Because the Eustachian tubes connect the middle ear to the back of the throat, the pressure surge can force air and bacteria into the ear canal, leading to infection or structural damage.

Beyond the ears, there is a risk of barotrauma to the sinuses. The intense pressure can force mucus or debris into the sinus cavities, potentially triggering a secondary sinus infection. In rare, documented instances, such as those reported in the BMJ Case Reports, patients have suffered spontaneous rupture of the pharynx—a condition where the soft tissues in the throat tear under the force of the redirected air. This is a medical emergency that requires immediate intervention to prevent life-threatening complications, such as mediastinitis, which is an inflammation of the central chest cavity.

Potential Impact on the Lungs and Blood Vessels

While reports of direct lung damage from a suppressed sneeze are exceptionally rare, the mechanics of the maneuver warrant caution. The pressure spike can cause a transient increase in intrathoracic pressure, which may briefly affect blood flow to the heart. For individuals with underlying cardiovascular conditions or those with pre-existing lung issues like emphysema, the sudden stress on the chest cavity is ill-advised.

Furthermore, the pressure surge can cause small blood vessels in the eyes or face to rupture, leading to subconjunctival hemorrhaging—the appearance of blood on the white part of the eye. While often harmless, these incidents serve as a physical reminder of the sheer force involved in a sneeze. The American Lung Association consistently highlights the importance of maintaining clear, unobstructed airways to ensure proper respiratory function and to prevent unnecessary trauma to the delicate mucosal linings of the throat and lungs.

Maintaining Proper Hygiene and Safety

The solution to avoiding these complications is to allow the sneeze to occur naturally while practicing good hygiene. The goal is to contain the aerosolized particles—which can travel several meters—without creating internal pressure traps.

• Use a tissue: Always cover your nose and mouth with a disposable tissue to capture droplets.
• The “elbow” technique: If a tissue is unavailable, sneeze into the crook of your elbow. This prevents the spread of pathogens while keeping your hands clean.
• Avoid pinching: Never pinch your nose or hold your mouth shut during a sneeze.
• Hand hygiene: Wash your hands thoroughly with soap and water for at least 20 seconds immediately after sneezing to reduce the transmission of viruses.

For those interested in further information on respiratory health and infection control, the World Health Organization provides comprehensive guidelines on respiratory etiquette. By respecting your body’s natural reflexes, you protect not only your own health but also the health of those around you.

If you experience persistent pain in the ear, throat, or chest following a forceful sneeze, it is advisable to consult a healthcare provider for an evaluation.
