Nosebleeds or in medical language called epistaxis, is bleeding from the nose that can occur at any age, both children and adults. Nosebleeds can be caused by things other than illness. Examples include a dry nose, picking your nose, or an injury. The most common causes of nosebleeds are dry air conditions and the habit of picking your nose. Both of these can cause the fine blood vessels in the nose to burst, causing bleeding. In addition to the two causes above, there are several factors that can increase the risk of nosebleeds, namely allergies. Nosebleeds that occur due to being too tired can also be considered normal. This happens because in the nasal mucosa there are small blood vessels that are fragile. When our condition is tired, the blood vessels in the nose become easily ruptured. These nosebleeds are generally harmless. However, you still need to be careful because nosebleeds may indicate the presence of certain diseases. Some of the symptoms to watch out for include nosebleeds that last more than 30 minutes. Sitting up straight, leaning slightly forward, and closing both holes by pinching your nose for 5 to 10 minutes can help stop nosebleeds. This process can be repeated to help stop the nosebleed.
