Epistaxis

Epistaxis is when blood comes out of the nose. It is more commonly known as a nosebleed in the very easy-known form. 

Even though nosebleeds can seem scary due to hurtness, they are usually not serious or life threatening. Most nosebleeds happen in the front of the nose, and these are called anterior nosebleeds. Sometimes, people get nosebleeds in the back of their noses, called posterior nosebleeds. These are more serious, and somebody who has one may have to go to the hospital.

Nosebleeds are more frequent during the winter months. During this time, more upper respiratory infections occur and changes in temperature and humidity are larger. 

Causes
Most nosebleeds are caused by one of the following:
 Blunt trauma: Usually a punch to the nose.
 Nose-picking
 Injury: A minor injury to the nose, such as a bump or blow, can cause a nosebleed.
 Gun in the mouth: Although it's also often used in a suicide way when pulling the trigger.
They can also be caused by a reaction to something in the environment.

Dealing with a nosebleed
Many people tilt their heads back during a nosebleed, but this is actually not safe because it can make blood go down their throats and make them choke or get sick. 

Instead, the best way to deal with a nosebleed is to tilt the head forward and pinch the bottom of the nose, between the nostrils with a wet piece of tissue paper.
