Coughing is a self-protection mechanism that helps remove foreign bodies, secretions, and pathogens from the respiratory tract. Sputum, on the other hand, is a common accompaniment to coughing, which is essentially a collection of respiratory secretions and may contain germs, dust, or other foreign bodies. Many people unconsciously swallow phlegm when coughing, but whether this act will cause harm to the body is a concern for many people. This article will detail the potential impact of this behavior and how to deal with it.
1. Composition and function of phlegm Sputum is mainly composed of water, mucus, cell debris, proteins, immune cells and possible pathogens. Normally, phlegm is part of the respiratory defense mechanism by helping to keep the respiratory tract moist and trapping and eliminating inhaled tiny particles and pathogens.
2. Potential risks of swallowing phlegmWhen sputum contains pathogens such as bacteria and viruses, swallowing sputum may bring these pathogens into the digestive tract. Although stomach acid kills most pathogens, some pathogens can still survive in the gut and even cause infection. In addition, if the sputum contains a large amount of harmful substances or irritating substances, long-term ingestion may cause irritation or slight damage to the mucosa of the digestive tract.
3. Assessing the effects of phlegm ingestionFor healthy adults, occasional phlegm ingestion usually does not cause significant harm to the body. A healthy person's digestive system is strong enough to handle these extra burdens. However, for people with weakened immunity, such as the elderly, chronically ill people, or immunosuppressed people, ingesting phlegm containing the pathogen may increase the risk of infection.
4. How to properly deal with cough and phlegm.
Stay hydrated: Drinking enough water can help thin your phlegm, making it easier to cough up.
Use steam or a humidifier: Steam can help open the airways, relieve coughing, and reduce the viscosity of phlegm.
Avoid irritants: Tobacco smoke, air pollution, and strong odors can all irritate the respiratory tract and increase phlegm volume.
Consult a doctor: If cough and phlegm persist or are accompanied by other symptoms, seek medical attention promptly.
Overall, swallowing phlegm occasionally does not cause serious harm to most people, but long-term or frequent ingestion of phlegm containing pathogens may have adverse health effects. Therefore, it is very important to maintain good respiratory hygiene and proper handling of cough and phlegm to maintain overall health. If you have any questions about your cough or phlegm, it's best to consult a medical professional for personalized advice and**.
