Nosebleeds are common in children, especially between the ages of 3 and 10. While they can seem alarming, most bloody noses in kids are not serious and are caused by something as simple as dry air or mild nasal irritation. However, there are times when a nosebleed may signal an underlying issue. Understanding when to be concerned about a nosebleed and what steps to take can help keep your child safe and comfortable.

what causes nosebleeds in children?

Most childhood nosebleeds start in the front (anterior) of the nose, where the blood vessels are more sensitive. Here are the most frequent causes:

• Dry air and nose-picking: These are the most common triggers. Heated indoor air during the winter months can dry out the nasal lining, leading to crusts that itch. When a child picks their nose, it can cause these crusts to break and bleed.
• Common colds and allergies: A stuffy or runny nose can cause frequent blowing, which irritates nasal tissues. Decongestants and antihistamines used to treat allergies can also dry out the nasal membranes, making bleeding more likely.
• Infections: Conditions like sinus infections or a sore throat and nose bleed combination may lead to nasal irritation. In some cases, you may even see a bloody nose with strep throat or nosebleeds when sick with viral infections.
• Injury: A blow to the nose, such as during sports or a fall, can cause a bloody nose. While most are minor, any injury with prolonged bleeding (longer than 10 minutes) or additional symptoms should be evaluated.
• Environmental irritants: Smoke, strong odors or chemical fumes can inflame the nasal passages, increasing the risk of bleeding.

toddler nose bleeding and infant nosebleeds

It’s not unusual to see toddler nose bleeding episodes during the dry winter months or when they have a cold. These are usually not dangerous. However, nose bleeding in infants is much less common and should always be evaluated. Babies have very delicate nasal passages, and bleeding could be linked to trauma, a foreign object or an underlying medical condition.

If your infant has a bloody nose, contact your pediatrician to determine the appropriate next steps.

nosebleeds in teenagers

Nosebleeds in teenagers may be caused by the same triggers as in younger children, such as dry air or nasal irritation. However, hormonal changes, stress or even medication use (like acne treatments) can also contribute. Teens who participate in sports may also experience nosebleeds from physical contact or injury.

If your teen has nosebleeds randomly or they occur during sleep, it’s worth discussing these episodes with a healthcare provider to rule out underlying issues.

symptoms to watch for in nosebleeds

Nosebleeds usually stop on their own within a few minutes. However, certain symptoms may indicate something more serious:

• Nosebleed does not stop after 5 to 10 minutes of firm pressure.
• Recurring nosebleed episodes or nosebleeds that happen frequently and without a clear cause.
• Bleeding from both nostrils at the same time.
• Child nosebleeds while sleeping, especially if it happens often.
• Nosebleeds accompanied by other concerning signs such as fatigue, bruising or weight loss.
• Family history of bleeding or clotting disorders.

If your child has any of these signs, it’s important to speak with your pediatrician or seek medical attention.

how to prevent nosebleeds

Many nosebleeds can be prevented with simple strategies:

• Use a humidifier in your child’s bedroom to keep nasal passages moist, especially in the winter.
• Apply saline nasal spray or gel to the inside of the nose daily.
• Keep fingernails trimmed to reduce the risk of scratching delicate nasal tissue.
• Encourage kids to avoid nose-picking and gently blow their nose.
• Use protective gear during sports to avoid injury to the face or nose.

These preventive measures are especially helpful for children who experience nosebleeds when sick or those prone to seasonal allergies.

treatments for nosebleeds

Here’s how to handle a nosebleed at home:

1. Stay calm and reassure your child.
2. Have them sit up and lean slightly forward (not back).
3. Pinch the soft part of their nose (just below the bridge) and hold for 5–10 minutes without letting go.
4. Place a cold compress on the bridge of the nose to help constrict blood vessels.

Do not let your child lie down or tilt their head back—this can cause blood to run down the throat, which may lead to coughing or vomiting.

In rare cases, further treatment might be required. A pediatric ENT specialist may recommend nasal cautery (sealing the blood vessels) or additional testing if an underlying condition is suspected.

when is a nosebleed serious?

Nosebleeds become more serious when:

• They don’t stop after 10 minutes of firm pressure
• They’re accompanied by frequent headaches, facial pain or vision changes
• Your child has other unexplained bruising or bleeding
• There’s difficulty breathing through the nose between episodes
• Nosebleeds are happening more often, such as daily or multiple times per week

If any of these situations arise, contact your child’s healthcare provider or seek care from a pediatric ENT specialist.

how long should nosebleeds last?

Most nosebleeds stop within 5 to 10 minutes with firm pressure. If the bleeding continues beyond that time or restarts shortly after stopping, it’s a good idea to get medical help. Persistent or prolonged nosebleeds could indicate an underlying condition that needs treatment.
