Symptoms of a dry nose include itching, bleeding and burning. There are a number of reasons a nose becomes dry. Generally, dry nose is just a symptom of another underlying issue. Treatment is not always necessary, but there are several things a person can do to relieve the effects of nasal dryness. The Mayo Clinic warns against prolonged use of petroleum jelly in the nose, but a small amount can be effective in rehydrating the nasal tissues. Other methods of treatment include the use of a humidifier, saline nasal sprays or antihistamine medication to treat allergies.
Breathing
Breathing through the nose is healthy as it helps capture any airborne pathogens that could cause illness. The hairs and mucus inside the nose are just one of the body's natural defenses against such illnesses. Despite being a healthy thing, breathing in hot, dry air can lead to nasal dryness. Cold climates cause frequent use of indoor heating units in order to stay warm. This central heating of the home and workplace can lead to dry air. Hot climates where the air is generally dry can also lead to nasal dryness.
Medications
Medicated nasal sprays, over-the-counter and prescription allergy medications have the potential for side effects, with dry nose being one of them. Unmedicated nasal sprays made with saline solution can be used to combat this type of nasal dryness during allergies or an illness. Replacing a medicated nasal spray with saline spray is recommended. Antihistamine medications work by reducing the body's natural reaction to allergens. This includes limiting sneezing and mucus production in the sinuses.
Picking
Obsessive-compulsive behavior can include unusual focus on germs, such as those found in the nose. A person may feel unclean until the nasal cavities have been rid of mucus. This can lead to frequently picking the nose with the fingers or tissues, which can cause the sensation of dryness. It can also lead to bleeding. The nose should be somewhat lubricated on its own at all times, but blowing too frequently can reduce the natural substances.
Rare Illness
Sjogren's syndrome and keratoconjunctivitis sicca are two rare illnesses with symptoms that include nasal dryness. Sjogren's syndrome is a disorder of the immune system that is characterized by dry eyes and dry mouth, says the Mayo Clinic. The mucus membranes stop producing normal levels of mucus, which can lead to dry nasal passages. Merck Manual explains that keratoconjunctivitis sicca is an illness affecting the eyes and tear ducts, but one possible symptom is dry nose from the lack of fluid secretions by the ducts.
