According to the American Academy of Otolaryngology, the nose contains a number of small blood vessels or arterioles, which can be easily broken and result in frequent nosebleeds. We can suffer from nosebleeds at any age, but the American Academy of Otolaryngology reports that they are most common in children between the ages of two and 10 and adults between the age of 50 and 80. The Mayo Clinic reports that you should seek medical assistance if the nosebleed lasts longer than 20 minutes.
Heat, Cold and Dry Climate
Drying out of nasal membranes can lead to anterior nosebleeds, or bleeding from the front of the nose. According to the Mayo Clinic, dry nasal passages are a leading cause of nosebleeds. The American Academy of Otolaryngology reports that these types of nosebleeds are quite common in dry climates or during the winter months when we heat our houses. As a result, nosebleeds can occur in the morning after sleeping all night in the dry air or at night after we have been out in the cold or dry weather. The American Academy of Otolaryngology reports that the drying effects of heat and cold or dry climates causes our nasal membranes to crust, crack and bleed. However, the American Academy of Otolaryngology report that this type of nosebleed can be prevented by applying a light coating of petroleum jelly to the nasal membrane or using an antibiotic ointment and rubbing it on the nasal membrane. This will help to keep your nasal membranes moist and less likely to crack and bleed.
Allergies, Infections and Colds
Sometimes when we have a cold or allergies, our nasal membranes become inflamed and this too can cause nosebleeds at both the morning and night. In addition, when we have a cold we suffer from congested nasal passages and resort to using nasal decongestants, which can irritate and dry the nasal passages. This can also cause nosebleeds, especially if you overuse the nasal decongestants. The excessive blowing of our noses can also cause the thin tissue in our noses to tear and may result in a nosebleed. According to the American Academy of Otolaryngology, allergies and infections can cause itching and this may cause us to pick our noses, which can also cause nose bleeding.
A deviated septum occurs when the partition between our two nasal chambers becomes crooked. According to Merck, a deviated septum can make you more susceptible to nosebleeds. In fact, the Mayo Clinic reports that one symptom of a deviated septum is nosebleeds. The Mayo Clinic also reports that nosebleeds can occur when the surface of your nasal septum becomes dry. Homeopathy for Everyone reports that a deviated septum allows foreign objects to injure the nasal canal and cause nosebleeds. Merck reports that a deviated septum may cause a nasal obstructions, and this can cause infections and injuries to the nasal canal, which lead to excessive nosebleeds. As a result, nosebleeds can occur during the morning or at night.
