Unveiling the Mystery: Delving into the Common Causes of Nosebleeds

Nosebleeds, medically known as epistaxis, are a common health problem affecting a wide range of the population. Often benign and not serious, it mainly occurs when the blood vessels inside the nose rupture. Various factors can trigger this condition, some of which are relatively minor, while others can be a sign of more serious health problems.

Climatic and environmental factors

Dry air and low humidity

One of the main causes of nosebleeds is exposure to a dry environment. Whether it’s cold, dry winter air or prolonged use of heating or air conditioning, these conditions can dry out the mucous membranes in the nose, making them more fragile and prone to bleeding.

Temperature changes

Sudden temperature variations between the heated interior and the cold exterior can also alter the resistance of nasal blood vessels, promoting the occurrence of bleeding.

Anatomical and physiological reasons

Hair fragility

Due to the richness of the capillary network in the anterior region of the nose, this area, called the Kiesselbach Locus, is particularly vulnerable to hemorrhages. In some people, innate capillary fragility can explain repeated episodes of nosebleeds.

Nasal deformities

Anatomical abnormalities such as a deviated nasal septum increase the risk of bleeding due to altered airflow and localized drying of the mucous membranes.

Medical and pathological explanations

High blood pressure

Individuals with hypertension are more likely to experience epistaxis, as increased blood pressure can cause fragile vessels to rupture.

Coagulation disorders

Bleeding disorders, such as hemophilia or taking anticoagulant medications, increase the risk of prolonged or recurring nosebleeds by affecting the ability of blood to clot normally.

Respiratory infections

Infections such as colds or sinusitis can lead to inflammation and irritation of the nasal mucous membranes, which predisposes to bleeding.

Lifestyle habits and drug use

Inappropriate nasal maneuvers

It is common for bleeding to result from everyday actions such as blowing your nose too forcefully or picking your nose. These actions can damage the nasal mucosa and cause bleeding.

Drug use

The use of drugs, especially those that are inhaled through the nose such as cocaine, can cause significant damage to the nasal walls and significant bleeding.

The consequences of modern life

Atmospheric pollution

Pollution can irritate the nasal mucosa and contributes to the increase in cases of nosebleeds, especially in urban areas with high air pollution.

Technology and radiation

Although less obvious, exposure to electromagnetic fields from electronic devices is sometimes mentioned as a factor that can influence the health of the mucous membranes.

Solutions and treatment

Treating a nosebleed usually involves simple measures like sitting up, tilting your head forward slightly, and pinching your nose to stop the blood flow. To prevent their occurrence, it is advisable to maintain good humidification of the nasal passages with seawater-based sprays and to avoid irritants. Any underlying cause, such as hypertension or a bleeding disorder, should also be treated in collaboration with a healthcare professional.


New studies continue to seek to better understand and treat epistaxis more effectively. Advances in the medical field and improvements in environmental quality of life are constantly evolving avenues that could help reduce the incidence of nosebleeds.

Adequate management of the underlying causes as well as education and awareness on the right actions to adopt are essential to limit the risk of epistaxis and its possible complications.

Knowing how to recognize the different factors contributing to nosebleeds is essential to adopt adequate preventive measures and to intervene appropriately when they occur. A thorough understanding of the common causes of epistaxis and the adoption of preventive behaviors can significantly reduce the frequency and severity of these incidents.

The nose, with its complex structure and essential function, requires attention and care. Therefore, when symptoms such as nosebleeds appear, do not hesitate to consult a healthcare professional to obtain a precise diagnosis and an appropriate treatment plan, best guaranteeing the maintenance of good nasal health.
