5 of the Most Common Causes of Nosebleeds

Have you ever had a nosebleed for what seemed like no good reason at all? There are a handful of common causes for nosebleeds, including trauma, allergies, and even the taboo act of picking your nose. Here are some things you should know so that you can attempt to avoid nosebleeds in the future.

Epistaxis, or a nosebleed, is a common occurrence and for the most part is of little to no concern to most people. Though blood running from the nose can be a frightening experience, especially for a first-timer or a young child, most nose bleeds will resolve on their own. Knowing the more common causes of nosebleeds can help subdue fears and make the nosebleed more tolerable.


Trauma directly to the nose or head area can result in a nosebleed. Trauma to the head that results in a nosebleed should be evaluated by a doctor as soon as possible. Trauma to the nose should also be evaluated, but trauma directly to the nose is usually more easily recognized as the cause of the nosebleed. The use of helmets and proper gear, especially when participating in sports, can help reduce the chances of trauma and nosebleeds.


Living in a house or being in a room where the air is particularly dry can result in a nosebleed. This is because the tissues become dry and eventually they can crack open, resulting in bleeding. Fortunately, this is easily remedied by using a humidifier or a vaporizer to help add additional needed humidity to the dry air.


Allergies can cause serious irritation to the nasal cavity. Constantly blowing your nose, rubbing the nose or constant drainage and irritation can result in a nosebleed. Again, much like with other causes of nosebleeds, an allergy-induced nosebleed will typically resolve on its on or with treatment of the allergies.

Blowing Your Nose

In some instances, a person can suffer from a nosebleed simply because they blew their nose too hard. This is because blowing too hard can irritate the nasal cavity and even cause some of the small blood vessels within the nose to burst, resulting in the nosebleed. Again, much like with any nosebleed, this type of nosebleed tends to resolve itself.

Picking at the Nose

Though it's regarded as a taboo behavior, it's not that uncommon for people to pick their noses, especially when in private. Unfortunately, picking too often or being an aggressive picker can result in a nosebleed. However, as with the majority of nosebleeds, nosebleeds causing by picking at the nose typically resolve themselves.

90 percent of all nosebleeds are the result of some type of issue with the anterior (front) area of the nose. Fortunately, these types of nosebleeds are not considered a serious medical issue and as noted earlier, all tend to resolve themselves. However, nosebleeds that become more frequent or don't stop should be evaluated by a doctor to see if another underlying cause is present.

Antihistamines, Hay Fever and Allergy Medication

Taking an antihistamine for colds, hay fever or allergies can also dry the inside of the nose. This is why it seems some people get a bloody nose right after having a cold, from taking all of those cold medicines to dry up a runny nose.

Ask your pharmacist if there are any allergy or cold medications that will not dry up the nose.

High Blood Pressure

Sometimes bloody noses can be caused by high blood pressure. Have your blood pressure checked so you can be sure. If you do find out you have blood pressure, you can take steps to lower your blood pressure.

Thinning of the Blood

Blood thinner medications can also cause bloody noses. This can cause fear in the person, since blood thinners can cause a bloody nose to take longer to stop.

There are other reasons for thinning of the blood other than medications. Drinking alcohol for a long period of time can also thin the blood.

Some medications other than blood thinners can also cause thinning of the blood, such as aspirin and NSAIDs can also thin the blood.

Also, some supplements also cause the blood to thin. Supplements like fish oil, and magnesium. Just make sure to not overdo certain supplements.

How to Keep the Nose Moist

There is one product that is excellent to keep the nose cavity moist. It is called Ayr (pronounced Air), saline nasal gel with aloe vera.

Some say that using petroleum jelly or Vaseline is good, but in reality, it is not very good to use. First of all, it is a petroleum product and it can actually inhibit breathing through the nose.

Using a humidifier in the house as mentioned above, and if you don’t have one, you can boil water on the stove which will add moisture to your home.
