What causes nose bleeding due to cold

The main cause of nosebleeds during a cold is typically the swelling of blood vessels due to inflammation and decongestion. Cold symptoms often lead to a runny nose, which can irritate the delicate membranes in the nasal passages. This irritation can cause the blood vessels to become more fragile and prone to rupture, resulting in a nosebleed. Additionally, the dryness of the air during colder weather can also contribute to nosebleeds. The dryness can make the membranes in the nose more prone to cracking and bleeding. To prevent nosebleeds during a cold, it is important to stay hydrated, use a humidifier to add moisture to the air, and avoid picking or blowing your nose excessively. If a nosebleed occurs, it is important to remain calm and apply pressure to the affected area to stop the bleeding. If the bleeding persists or is severe, it is recommended to seek medical attention immediately.
