Holding in a sneeze can have certain effects on the body. Sneezing is a self-protection mechanism of the human body, helping to clear foreign bodies or irritants from the nasal cavity. When we hold in a sneeze, it may cause some potential harm to the body. Firstly, holding in a sneeze leads to a sudden increase in pressure in the nasal cavity and ears. During a sneeze, the speed of airflow can reach 160 kilometers per hour, and holding it in is like exerting a huge pressure on the nasal cavity and ears. This pressure can cause eardrum damage and even eardrum perforation in extreme cases. Imagine forcefully pinching the outlet of a water hose; the water has nowhere to go, and pressure builds up inside the hose, potentially damaging it. Secondly, holding in a sneeze may cause sinus problems. Sinuses are air-filled cavities in the head. When sneezing, the pressure inside the sinuses temporarily rises, and if the sneeze is held in, the pressure cannot be released, potentially leading to sinusitis or exacerbating existing sinus issues. It's like a fully loaded truck being forced to stop suddenly while climbing a hill, increasing the burden. Additionally, holding in a sneeze can adversely affect blood vessels. Holding in a sneeze increases intracranial pressure, raising the risk of blood vessel rupture, especially for those with hypertension or fragile blood vessels. In such cases, it may cause small blood vessels in the eyes or brain to rupture, leading to bleeding. To avoid these potential risks, it is recommended not to hold in sneezes. If you are concerned about the loud sound or droplets affecting others, gently cover your mouth and nose with a tissue or your elbow to maintain hygiene and avoid harm to your body. Remember, sneezing is a natural physiological reaction, and letting it happen naturally is the healthiest choice. By taking these simple measures, you can protect both yourself and others better.
