Nosebleed First Aid: How to Stop a Nosebleed, What Not to Do and When to Get Help

Quick answer: sit upright and lean slightly forward, not back. Pinch the soft part of the nose, just below the bony bridge, firmly closed with your thumb and finger, and hold steady pressure for 10 to 15 minutes without letting go to check. Breathe through your mouth and spit out any blood rather than swallowing it. Get emergency care if bleeding lasts longer than about 20 minutes despite pressure, follows a head or face injury, is very heavy, causes trouble breathing, or happens in someone taking blood thinners.

Nosebleeds look alarming, especially on a white shirt or a child’s pillow, but most are minor and stop with the right first aid. They are especially common in winter, when heating systems dry out indoor air, and city apartments with radiators can be some of the driest places around.

The catch is that the most familiar advice, tipping the head back, is wrong. This guide covers the steps recommended by medical sources, what to avoid, how to prevent repeat nosebleeds at home and when a nosebleed becomes an emergency. It belongs to our apartment emergency kit and preparedness guide.

This article is general safety information, not medical advice. Call 911 in an emergency and contact a health care provider about frequent or severe nosebleeds.

Why Nosebleeds Happen

The inside of the nose is lined with many small blood vessels close to the surface, which makes them easy to break. ENT Health explains that most nosebleeds start in the front part of the nose, from vessels on the wall between the nostrils. These are called anterior nosebleeds and are usually easy to control at home.

Common triggers listed by MedlinePlus and ENT Health include:

• Dry air, especially from indoor heating in winter
• Picking or rubbing the nose
• Blowing the nose hard
• Colds, sinus infections and allergies
• A blow to the nose
• Some medications, such as blood thinners and some nasal sprays
• Irritants such as smoke or chemical fumes

Less often, a nosebleed starts deeper in the back of the nose. These posterior nosebleeds are more common in older adults, can be heavier and may need medical treatment.

How to Stop a Nosebleed: Step by Step

These steps match guidance from MedlinePlus, ENT Health and the American Red Cross.

1. Stay calm and sit down. Sitting lowers the chance of fainting and makes the next steps easier.
2. Lean slightly forward. Keep the head level or tipped a little forward so blood runs out of the nose, not down the throat.
3. Pinch the soft part of the nose. Use your thumb and index finger to press both nostrils together firmly, just below the hard bony bridge. Pinching the bony part does not help.
4. Hold pressure for 10 to 15 minutes. Use a clock or timer. Do not let go to check whether it has stopped, since that can restart the bleeding.
5. Breathe through your mouth.
6. Spit out blood. Swallowed blood can cause nausea and vomiting.
7. Use a cold compress if you like. A cool cloth or a wrapped ice pack on the bridge of the nose or cheeks may help some people, though pressure is the main treatment.
8. Check after 10 to 15 minutes. If it is still bleeding, repeat firm pressure for another 10 to 15 minutes.

Why not tilt the head back?

Tipping the head back does not stop the bleeding. It only sends blood down the throat, where it can be swallowed, cause vomiting or, in rare cases, be inhaled. Leaning forward lets you see whether the bleeding is slowing and keeps the airway clear.

Should you stuff the nose with tissue?

Medical sources focus on pinching rather than packing. Stuffing tissue or cotton into the nose can pull off the clot when it is removed and restart the bleeding. Hold a tissue or cloth under the nose to catch drips while you pinch.

After the Bleeding Stops

A fresh clot is fragile for the first hours and days. ENT Health and MedlinePlus suggest:

• Do not blow, pick or rub the nose for several hours, and blow gently for the next few days.
• Avoid bending over, heavy lifting and straining for the rest of the day.
• Avoid very hot drinks and hot showers for a few hours, since heat widens blood vessels.
• Keep the head higher than the heart when resting.
• Sneeze with your mouth open if you can.

If bleeding restarts, sit, lean forward and apply pressure again.

When to Get Emergency Care

Call 911 or go to an emergency department if:

• The bleeding does not stop after about 20 minutes of steady pressure
• The nosebleed follows a head injury, a fall, a car crash or a blow to the face
• The bleeding is very heavy or blood is pouring down the throat
• The person has trouble breathing
• The person feels faint, dizzy or very weak, or looks pale and clammy
• The person takes blood-thinning medication and the bleeding is heavy or prolonged
• A young infant has a nosebleed

After a head injury, also watch for confusion, vomiting or worsening headache, and see our guide to head injury and concussion warning signs. A broken nose may look crooked or swollen and needs medical evaluation.

See a provider soon if

• Nosebleeds happen often, such as several times a week
• You bruise easily or bleed heavily from small cuts
• Nosebleeds started after beginning a new medication
• There is a blockage, crusting or a growth in the nose
• You have high blood pressure that is not well controlled

A provider can look inside the nose, check for causes and, if needed, seal a problem vessel.

Nosebleeds in Children

HealthyChildren.org from the American Academy of Pediatrics notes that nosebleeds are common in children, often from nose picking or dry air, and most are harmless. The same steps work for kids:

• Have the child sit up and lean forward.
• Pinch the soft part of the nose for 10 minutes, timed by the clock.
• Comfort the child and encourage breathing through the mouth.
• Discourage picking afterward; trimming fingernails helps.

Call the child’s doctor if nosebleeds happen frequently, if bleeding is hard to stop, or if the child bruises easily. Seek emergency care if bleeding will not stop after 10 to 20 minutes of pressure, if the nosebleed follows a hard blow to the head, or if a child under 2 has a nosebleed without a clear cause. If a young child may have put an object in the nose, have it checked rather than trying to remove it yourself.

Nosebleeds and Blood Thinners

People who take anticoagulants or antiplatelet medicines may bleed longer from any small injury, including a nosebleed. Do not stop or skip these medications on your own because of a nosebleed. Apply pressure as described, and call the prescribing provider or seek care if the bleeding is heavy, prolonged or frequent. Keep a current medication list in your emergency kit so responders know what you take.

Preventing Nosebleeds in a Dry Apartment

Winter heating can drop indoor humidity sharply. ENT Health and MedlinePlus suggest a few steps:

• Use a humidifier in the bedroom during the heating season. Clean it as the manufacturer directs to prevent mold and bacteria growth.
• Use saline nasal spray or gel to keep the inside of the nose moist.
• Apply a thin layer of petroleum jelly or a water-based nasal gel just inside the nostrils, if your provider agrees.
• Avoid picking the nose, and keep children’s nails short.
• Blow gently, one nostril at a time.
• Avoid smoking and secondhand smoke, which dry and irritate the nose.
• Drink enough fluids to stay hydrated.

Radiators and overheated units

Many older apartment buildings run steam heat that tenants cannot easily adjust. A small humidifier, a bowl of water near the radiator and keeping bedroom doors closed to hold in humidity can all help. If your apartment is overheated to the point of discomfort, check your city’s heat rules and talk to building management.

Helping Someone Else With a Nosebleed

When you are helping a coworker, a neighbor or a stranger, the steps are the same, with a few additions:

• Put on gloves if you have them, or have the person pinch their own nose while you coach them.
• Give them something to catch the blood, such as a towel, a bowl or a stack of paper towels.
• Time the pressure for them. People tend to let go early; say when 10 minutes have passed.
• Watch for signs of feeling faint, such as pale, sweaty skin or dizziness. If they feel faint, help them sit lower or lie on their side with the head slightly raised, and keep pressure on the nose.
• Ask about medications and injuries. Blood thinners or a recent fall change the plan toward getting medical care sooner.
• Clean up safely. Wash your hands after helping and wipe surfaces with a household disinfectant.

Nosebleeds During Emergencies

Some disaster conditions make nosebleeds more likely. Smoke from wildfires or building fires irritates the lining of the nose, and dry air during long power outages in cold weather, when people run space heaters, can do the same. Protect your airway with a well-fitting mask rated for particles when outdoor air quality is poor, keep saline spray in your emergency kit and drink enough water.

If a nosebleed happens when emergency services are stretched, such as during a major storm, the home steps still work for most bleeds. Save 911 for the warning signs listed above, and if you cannot get through, keep applying firm pressure and try again.

Myths About Nosebleeds

Several popular remedies do not help. Home remedies such as putting ice down the back of the neck or pinching the top of the nose between the eyes are not part of the first aid steps that MedlinePlus, ENT Health or the Red Cross recommend. Lying flat makes things worse by sending blood into the throat. Firm, steady pressure on the soft part of the nose while leaning forward is the method medical sources recommend.

Quick Reference: Do and Do Not

Do	Do not
Sit up and lean slightly forward	Tilt the head back or lie flat
Pinch the soft part of the nose firmly	Pinch the bony bridge
Hold for 10 to 15 minutes by the clock	Let go every minute to check
Breathe through the mouth and spit out blood	Swallow blood
Rest and avoid straining afterward	Blow or pick the nose for several hours
Get help if bleeding lasts about 20 minutes	Wait it out for an hour

Supplies to Keep on Hand

Your small apartment first aid kit probably has most of these already:

• Tissues and soft cloths
• Disposable gloves, for helping someone else
• A cold pack
• Saline nasal spray or gel
• A timer or clock you can see
• A current medication list for each household member

Frequently Asked Questions

Should you tilt your head back for a nosebleed?

No. Lean slightly forward so blood does not run down the throat, and pinch the soft part of the nose.

How long should I pinch my nose?

Hold firm pressure for 10 to 15 minutes without letting go to check. Repeat once if bleeding continues.

When is a nosebleed an emergency?

When it lasts more than about 20 minutes despite pressure, follows a head or face injury, is very heavy, causes trouble breathing or occurs in someone on blood thinners with heavy bleeding.

Why do I get nosebleeds in winter?

Indoor heating dries the air and the lining of the nose, making small blood vessels more likely to crack and bleed. A humidifier and saline spray can help.

Are frequent nosebleeds in kids a concern?

Most are harmless and caused by dry air or nose picking, but talk to the child’s doctor if they happen often, are hard to stop or come with easy bruising.

The Bottom Line

To stop a nosebleed, sit up, lean forward and pinch the soft part of the nose firmly for 10 to 15 minutes without checking. Spit out blood, rest afterward and avoid blowing the nose for a while. Keep apartment air moist in winter to prevent repeat bleeds, and get emergency care for bleeding that will not stop, heavy bleeding, trouble breathing or a nosebleed after a head injury.
