Why Am I Having Blood in Snot Only in the Morning?

Finding a little blood in your snot in the morning can be due to mild nasal dryness or irritation that happens overnight and is often not a serious problem.

Explanation

When you sleep, the air in your home might be dry, or you might breathe through your mouth, which can dry out the inside of your nose. This dryness makes the small, delicate blood vessels inside the nose more likely to break, causing a tiny bit of blood to mix with your mucus. Allergies, like those from pollen or dust, can also make the inside of your nose irritated or inflamed. Sometimes, if you blow your nose hard when you wake up, you can cause small blood vessels to break which leads to a small amount of bleeding. High blood pressure or sleep apnea may contribute to nosebleeds but these are less common causes. If the bleeding frequently or is heavy, it's important to talk to a doctor for a more comprehensive evaluation.
