When experiencing a nosebleed, many people instinctively tilt their head backward, believing this prevents blood from flowing out. However, this approach is not only unscientific but can also be risky. Tilting the head back causes blood to flow backward into the throat and possibly be swallowed into the stomach, which may irritate the stomach lining—leading to nausea or vomiting—and obscure the true severity of the bleeding, delaying proper assessment and treatment.The correct method is to sit upright or lean slightly forward, pinch the soft part of the nose (the nostrils) firmly for about 10–15 minutes, and breathe through the mouth. This allows blood to drain safely out through the front of the nose, preventing aspiration or swallowing. Applying a cold compress to the forehead or bridge of the nose can also help constrict blood vessels and stop the bleeding. If bleeding persists for more than 20 minutes or recurs frequently, seek medical attention promptly.It’s especially important for children and older adults to avoid tilting the head back during a nosebleed. Knowing the proper first-aid technique not only helps control bleeding effectively but also prevents potential complications and ensures better health and safety.
流鼻血时，很多人第一反应是仰头，认为这样可以防止血液流出。然而，这种做法其实并不科学，甚至可能带来风险。仰头会使鼻腔内的血液倒流入咽喉，进而被吞咽进入胃部，不仅可能刺激胃黏膜引起恶心或呕吐，还可能掩盖出血的真实情况，延误判断和处理。正确的处理方式是：保持身体直立或略微前倾，用手指捏住鼻翼（软骨部分）约10-15分钟，同时用嘴呼吸。这样可以让血液从前鼻孔自然流出，避免误吸或吞咽。此外，可在额头或鼻梁处冷敷，帮助血管收缩止血。若鼻血持续超过20分钟仍未止住，或频繁反复发作，应及时就医。特别提醒儿童和老年人，更应避免仰头止血。掌握科学的止血方法，不仅能有效控制出血，还能预防并发症，保障健康安全。
