A nosebleed, also known as epistaxis, occurs when there is bleeding from the blood vessels in the nose. It can be caused by a variety of factors such as dry air, picking or blowing the nose too hard, trauma to the nose, or underlying medical conditions. Nosebleeds are typically not serious and can be easily treated at home by applying pressure to the nose and tilting the head forward. However, in some cases, medical attention may be needed if the bleeding is severe or recurrent.
