Introduction
1. Excessive internal heat (“shang huo”) is a major cause of epistaxis (nosebleeds). In particular, most people today maintain irregular daily routines, and staying up late has become commonplace—over time, this can lead to excessive liver fire.
2. Fragile nasal mucosa can also cause unexplained nosebleeds. Especially in dry weather, when nasal humidity is insufficient, the nasal mucosa may become damaged and fissured, resulting in congestion and subsequently triggering bleeding.
Nosebleeds (epistaxis) are a very common physiological phenomenon in daily life. Although not a serious illness, frequent nosebleeds can harm the body. So, what causes recurrent nosebleeds?
Causes of Frequent Nosebleeds
1. Excess internal heat (“fire”) is a major cause of nosebleeds. Nowadays, most people maintain irregular daily routines, and staying up late has become commonplace. Prolonged sleep deprivation may lead to liver fire.
2. Fragile nasal mucosa can also trigger unexplained nosebleeds. Especially during dry weather, insufficient humidity in the nasal cavity may damage and crack the mucosa, causing congestion and subsequent bleeding.
3. External trauma to the nose. For example, patients with allergic rhinitis often experience nasal discomfort during flare-ups. If intense itching occurs, habitual nose-picking with fingernails can easily tear the nasal mucosa, resulting in bleeding.
4. Sinusitis or nasal tumors.
If you experience recurrent nosebleeds, it is advisable to visit a hospital for blood tests—including a complete blood count (CBC) and coagulation function assessment—to check for thrombocytopenia or prolonged clotting time. If both tests yield normal results, consult an otolaryngologist (ENT specialist) for a thorough examination of the nasal cavity to assess for structural abnormalities—such as deviated nasal septum—that may contribute to epistaxis.
When a nosebleed occurs, gently pinch the soft part of the nose (the nasal bridge) with both hands and hold for several minutes. You should observe noticeable hemostasis within one to two minutes. Alternatively, applying a cold towel (soaked in cold water) to the forehead may also help control bleeding. We hope this information proves helpful. Wishing you good health and happiness!
