1. Dry air: Dry air can cause the nasal passages to become dry and irritated, leading to the development of nosebleeds.
2. Trauma: Trauma to the nose, such as a blow to the face or picking the nose aggressively, can cause blood vessels in the nasal passages to rupture and result in anterior epistaxis.
3. Nasal infections: Infections in the nasal passages, such as sinusitis or rhinitis, can cause inflammation and irritation of the blood vessels, leading to nosebleeds.
4. Allergies: Allergic reactions, particularly to environmental allergens like pollen or dust mites, can cause nasal congestion and inflammation, increasing the risk of anterior epistaxis.
5. Medications: Certain medications, such as blood thinners or nasal sprays containing corticosteroids, can increase the likelihood of nosebleeds by interfering with blood clotting or causing nasal dryness.
