You’ve just felt a little tickle in your nose, and when you go to wipe it away you discover a trickle of bright red blood. Don’t panic; there are several reasons why nosebleeds occur, and not all of them are serious. To stop a nosebleed, staff at the Mayo Clinic recommend remaining upright to avoid extra blood flow to the veins inside your nose. Lean forward and apply pressure to your nose by pinching your nostrils shut for 10 to 15 minutes. Once the bleeding has stopped, you can apply a small amount of petroleum jelly or antibiotic ointment to the inside of your nose. This will moisturize the area and prevent more bleeding. Knowing the causes of nosebleeds can help you both prevent them and recognize when you might need to contact your doctor.
10. Dry Air
The number one cause of nosebleeds is dry air. A dusty climate, air conditioning, and the use of central heating all can create a dry atmosphere that dries out nasal membranes. If you live in an arid region or find that heating or air conditioning is drying out your home, use a humidifier to replace moisture in the air and keep your nasal lining happy. A dab of antibiotic ointment gently applied to the inside of your nose with a cotton swab at bedtime can also help lubricate your nasal membranes.
9. Nose Picking
If your nasal passages have become dry, it may be tempting to pick at the crust that forms on your membranes. Don’t do it! Keep your nasal membranes moist with an over-the-counter saline spray or gel and keep those fingers away from your nose. Use a humidifier to keep the air in your home moist and prevent drying out your nasal membranes.
