Nosebleed: Why Not to Tilt Your Head Back, and What Works Instead

When your nose bleeds, sit down, lean forward and pinch the soft part of your nose for 10–15 minutes without letting go. Tilting your head back does not stop the bleeding: the blood runs into your throat, you swallow it and may be sick, and some can go down the wrong way. Steady pressure is usually all that is needed.

When to see a doctor

Now — emergency (UK, NHS: go to A&E or call 999): the bleeding has not stopped after 10–15 minutes of continuous pressure; it seems very heavy or spurts; you swallow so much blood that you vomit; you find it hard to breathe; you feel weak or dizzy, turn pale or pass out; the nosebleed started after a blow to the head or face. Do not drive yourself (NHS). In the US, the American Red Cross likewise advises calling 911 for heavy or gushing bleeding, bleeding after a head or neck injury, or bleeding that has not stopped after 15 minutes of pressure. In the EU, call 112.

Today: you take a blood thinner and a nosebleed is hard to stop — contact the doctor who prescribes it quickly, and do not stop the medicine on your own. If the bleeding was heavy, do not take the next dose until a doctor has seen you, and do not put that visit off (AAO-HNS patient guide, US). If it will not stop with pressure, that is the emergency tier above.

Routine: nosebleeds that keep coming back — for example, several times a month (IFRC); signs of anaemia or a known bleeding disorder; any nosebleed in a child under 2 (NHS; IFRC).

What is happening

Where the blood comes from. Most nosebleeds start in a web of small vessels at the front of the wall between the nostrils (MedlinePlus). The usual triggers are nose picking, blowing too hard, dry air and a dried-out lining, and injury; blood thinners such as warfarin and other anticoagulants, clopidogrel and aspirin make bleeding more likely (NHS; MedlinePlus). Children aged about 2 to 10 get nosebleeds especially often, most often from a finger in the nose (NHS inform; IFRC).

Why pinching the soft part works. Pressing the lower, soft third of the nose, just above the nostrils, squeezes that area of vessels shut. IFRC calls this pressure "the only first aid intervention needed in most cases". The bony bridge higher up is the wrong place to press (NHS; St John Ambulance).

Why not head back. "Tilting the head backward causes blood to flow into the throat, which can lead to nausea, vomiting" (IFRC, 2025). Blood can also get into the airway and make you choke (St John Ambulance; British Red Cross). Lying down is not a better option: staying upright lowers the pressure in the vessels of the nose (NHS inform), and MedlinePlus says plainly that lying down with a nosebleed is not recommended.

How strong the evidence is. Every guideline advises sitting and leaning forward, but no studies have compared positions; the advice rests on expert consensus (IFRC, 2025). The ideal pressing time has not been studied either — the one clinical trial used 15 minutes.

Blood pressure. People with high blood pressure have nosebleeds more often, but no source shows that a single nosebleed is "caused by pressure". Frequent nosebleeds are a reason to check your blood pressure.

What to do

Sit down and lean forward, mouth open, breathing through your mouth.
Pinch the soft part of the nose firmly with thumb and finger and hold for 10–15 minutes by the clock. Do not let go early to check.
Spit out blood that reaches your throat rather than swallowing it.
Cold is optional. The NHS says an ice pack on the bridge of the nose may help but the evidence is weak; IFRC 2025 does not recommend cold as first aid. Pressure is what counts.
Do not stuff the nose with cotton wool or gauze (MedlinePlus). Packing the nose is a hospital procedure (NHS).
For 24 hours after it stops (NHS): do not blow or pick your nose, do not pull off scabs, avoid hot drinks, alcohol and strenuous exercise, and do not lie flat.

Myths to drop: head back; lying down; ice on the back of the neck — tests on volunteers found little or no effect of cold on the forehead or neck on blood flow in the nose (ILCOR scoping review, 2021).

When this is not the case

Blood thinners. Do not stop them on your own; for bleeding that is not life-threatening, doctors first treat the nosebleed rather than stopping the drug (AAO-HNS guideline, 2020).
Nasal sprays. If a doctor has advised a spray for nosebleeds, use it as they said. Frequent use of decongestant sprays can itself cause nosebleeds (NHS inform; MedlinePlus) — see what actually helps with a cold.
After a blow to the head, also check the signs of concussion.
