Nosebleeds are common due to the location of the nose on the face, and the large amount of blood vessels in the nose. The most common causes of nosebleeds are drying of the nasal membranes and nose picking (digital trauma), which can be prevented with proper lubrication of the nasal passages and not picking the nose.

Excessive sneezing from hay fever can damage tissues in the nose, and repeated sneezing and nose-blowing could rupture blood vessels, which would cause a nosebleed. Nasal spray used to treat hay fever symptoms could also cause a nosebleed, as the chemicals can sometimes be quite harsh.

If your nose is hit or if it is scratched inside, the vessels may break and cause your nose to bleed. The most common cause is “picking” the nose. If a blood vessel inside your child's nose is very close to the surface, blowing the nose too hard or picking the nose may make it bleed.

Blood may come out of your nostrils, but blood can also leak into your throat. This type of nosebleed can be serious. It may be caused by injuries to your nose, but may also be caused by high blood pressure or other conditions.

Nosebleeds can occur spontaneously when the nasal membranes dry out and crack. This is common in dry climates, or during the winter months when the air is dry and warm from household heaters.

Usually a nosebleed from both nostrils is due to a heavy flow from one nostril; the blood has just backed up and overflown into the other. If blood drips down the back of the throat into the stomach you may spit up or vomit blood. Excessive blood loss can cause a feeling of dizziness, light-headedness and fainting.

In these cases, a nosebleed isn't directly caused by the stress you feel, though the two things may appear connected. Instead, it's caused by the situation that also caused the anxiety. Hypertension, or high blood pressure, has been suggested as a trigger for nosebleeds.

Nosebleeds are most often caused by local trauma but can also be caused by foreign bodies, nasal or sinus infections, and prolonged inhalation of dry air. Tumors and vascular malformations are also potential causes of nosebleeds, but they are rare. Spontaneous nosebleeds are fairly common, especially in children.

Heavy alcohol use Drinking heavily can contribute to the risk of nocturnal nosebleeds in two ways. First, alcohol interferes with the activity of the blood's platelets, which are the cells that cause blood to clot.

An injury to the nose can rupture blood vessels in and around the septum where there is both bone and cartilage. As the blood clots to stop the bleeding, it forms a hematoma. Hematomas in most other areas of the body are usually reabsorbed over time, much as happens to a bruise.

A person's nose can turn red because of changes in the surface of the skin or the blood vessels. When the skin is irritated or inflamed, the nose can look temporarily red. Blood vessels in the nose can also swell or break open, creating a red or swollen appearance.

The most common cause of nosebleeds is dry air. Dry air can be caused by hot, low-humidity climates or heated indoor air. Both environments cause the nasal membrane (the delicate tissue inside your nose) to dry out and become crusty or cracked and more likely to bleed when rubbed or picked or when blowing your nose.
