Stay calm and sit the person upright, slightly leaning forward. Pinch the soft part of the nose just below the bony bridge for 10–15 minutes without releasing. This helps stop bleeding. Breathe through the mouth and avoid lying down or tilting the head backward—it can cause blood to flow into the throat.
Apply a cold compress to the nose bridge. If bleeding continues beyond 20 minutes, seek medical care. Avoid nose-picking, blowing, or bending over for a few hours after bleeding stops. Common causes include dry air, nose injury, or high blood pressure.
