You likely get a bloody nose in the morning because the inside of your nose becomes dry, causing blood vessels to crack and bleed.
Why Dryness Leads to Nosebleeds
The nasal passages are lined with a delicate mucous membrane that keeps the area moist. When this membrane dries out, the blood vessels just beneath the surface become vulnerable. Several factors contribute to this dryness:
- Low Humidity: Dry air, especially during winter months or in climates with low humidity, can quickly dry out the nasal passages.
- Sleeping with Your Mouth Open: Breathing through your mouth while sleeping bypasses the nasal passages' natural humidifying function, leading to dryness.
- Nasal Congestion and Decongestants: Colds, allergies, or sinus infections can cause nasal congestion. Decongestant medications, while relieving congestion, can also dry out the nasal passages.
- Irritants: Exposure to irritants like smoke, dust, or chemical fumes can irritate and dry out the nasal lining.
- Nasal Picking: This common habit can injure the delicate blood vessels in the nose.
When It Happens at Night
You may wake up with a bloody nose because these drying effects are often exacerbated during sleep:
- Prolonged Exposure: The nasal passages are exposed to dry air for a longer, uninterrupted period overnight.
- Nasal Breathing: If you breathe mainly through your nose while asleep, the air passing through the nasal passages can further contribute to dryness.
How to Prevent Morning Nosebleeds
Here are some steps you can take to prevent bloody noses in the morning:
- Humidify Your Bedroom: Use a humidifier to add moisture to the air, especially during dry seasons.
- Saline Nasal Spray or Gel: Apply a saline nasal spray or gel before bed to keep the nasal passages moist.
- Avoid Picking Your Nose: Resist the urge to pick your nose, as this can damage the delicate blood vessels.
- Stay Hydrated: Drink plenty of fluids to keep your mucous membranes hydrated.
- Petroleum Jelly: Apply a small amount of petroleum jelly (like Vaseline) to the inside of your nostrils with a cotton swab before bed. Be careful to apply it gently and not too far up the nose.
If nosebleeds are frequent, severe, or accompanied by other symptoms (such as difficulty breathing or excessive bleeding), consult a doctor.
