What could be causing frequent nosebleeds recently?

Generally, frequent nosebleeds recently may be caused by factors such as dry air, excessive stress, internal heat ("shanghuo"), rhinitis, or high blood pressure. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analysis is as follows:

1. Dry Air: Dry conditions can accelerate evaporation of moisture from the nasal mucosa, making local blood vessels more prone to rupture and bleeding. It is advisable to maintain indoor humidity by using a humidifier or regularly opening windows for ventilation.

2. Excessive Stress: High stress levels may lead to hormonal imbalances, affecting normal function of nasal blood vessels and causing nosebleeds, possibly accompanied by nasal dryness. It is recommended to learn emotional regulation techniques and reduce stress through relaxation activities such as deep breathing exercises or yoga.

3. Internal Heat ("Shanghuo"): This may be related to dry weather or insufficient water intake. "Shanghuo" can cause dryness of the nasal mucosa and increased fragility of capillaries, making them more likely to rupture and bleed. Patients are advised to follow medical advice and use medications such as Tianwang Buxin Dan, Niuhuang Qingfei Pian, or Yangyin Qingfei Wan for treatment.

4. Rhinitis: Usually caused by air pollution or prolonged inhalation of irritants. In patients with rhinitis, the nasal mucosa may become swollen and congested, leading to erosion or ulceration, which increases the risk of blood vessel rupture and bleeding. It is recommended that patients use medications such as Biyan Pian, Biyuan Tongqiao Keli, or Qianbai Biyan Pian under medical supervision to improve symptoms.

5. Hypertension: Often associated with arteriosclerosis or significant emotional fluctuations. In hypertensive patients, elevated blood pressure may cause rupture of arteries in the nasal cavity, resulting in localized bleeding. Patients should strictly follow medical advice and take antihypertensive medications such as bisoprolol fumarate tablets, verapamil hydrochloride tablets, or ramipril tablets to manage their condition.

In daily life, it is recommended to maintain a light diet and increase intake of vitamin-rich foods—such as apples, cucumbers, and tomatoes—to strengthen the resistance of the nasal mucosa and support recovery.
