How to Stop a Nosebleed
The right way to stop a nosebleed quickly — and why the most common advice (tilting your head back) is wrong.

Nosebleeds are common and almost always harmless. Most stop within 10–20 minutes with the right technique. The key is knowing what not to do.
The Right Technique
1. Sit upright and lean slightly forward.
Not backward. Leaning back causes blood to drain down your throat, which can cause nausea, vomiting, and in large amounts, can be dangerous. Leaning forward lets blood drain out of the nose rather than down the throat.
2. Pinch the soft part of the nose.
Use your thumb and index finger to firmly pinch the soft part of the nose — below the bony bridge. Breathe through your mouth.
3. Hold for 10–15 minutes without releasing.
Don't check every minute to see if it's stopped — this disrupts clotting. Set a timer and wait. Most nosebleeds stop within 10–15 minutes.
4. Release slowly and don't blow your nose immediately.
After 15 minutes, release gently. Avoid blowing your nose for several hours — it can dislodge the clot and restart the bleed.
What Causes Nosebleeds
Dry air — the most common cause. Dry air dries the nasal membranes and causes small blood vessels to crack. More common in winter with indoor heating.
Nose picking or blowing too hard — damages fragile blood vessels at the front of the septum (Kiesselbach's plexus — where most nosebleeds originate).
Trauma — a knock or blow to the nose.
Sinusitis or allergies — inflamed nasal passages with frequent blowing.
Blood thinners — medications like aspirin, warfarin, or ibuprofen taken regularly can make nosebleeds harder to stop.
High blood pressure — not a common direct cause but can make bleeding heavier.
After It Stops
- Don't blow your nose for a few hours
- Apply a thin layer of petroleum jelly (Vaseline) just inside each nostril with a cotton swab — this keeps the membranes moist and helps prevent recurrence
- Stay upright for a few hours; avoid bending over or heavy lifting
Preventing Recurring Nosebleeds
- Use a humidifier in winter
- Apply Vaseline inside the nostrils daily if you get frequent bleeds
- Stay hydrated
- Use a saline nasal spray to keep the nasal membranes moist
- Try not to blow your nose too forcefully
When to Seek Medical Attention
- The bleeding doesn't stop after 20–30 minutes of correct pressure
- Blood is very heavy (soaking through cloths rapidly)
- Bleeding follows a head injury
- You're also coughing or vomiting blood
- You're on blood thinners and the bleed won't stop
- Nosebleeds are frequent and you don't know why (worth a GP check to rule out blood pressure issues or a bleeding disorder)
