Nosebleeds are a common occurrence, and may indicate a severe medical condition. The rupture of the blood vessels within the front and back of the nose can cause such bleeding. These blood vessels are very tender and, thus, bleed easily.
There are two kinds of nose bleeds: namely anterior and posterior nosebleeds.
An anterior nosebleed occurs when the blood vessels at the front of the nose break or rupture, giving rise to bleeding. A posterior nosebleed is when the rupture takes place in a deeper part of the nose. The latter is more dangerous because blood can flow down the back of the throat.
Some of the causes of nose bleeding are:
- Trauma to the face, such as a punch on the face
- Repeated bouts of nose picking or irritation can also cause nosebleed
- Although rare, inability of the blood to clot can also cause the nose to bleed
- High blood pressure can also be a contributing factor
According to some people, cold can cause your nose to bleed. This holds true to an extent. Among the many reasons that can cause the nosebleed, summers serve as one.
This is because:
- Summer months are dry and hot, both of which are bad for your nose. The protective coating of mucus present within the nasal cavity can get dry due to low humidity in the hot months. The loss of the mucus causes your nasal cavity to be prone to dryness, leading to subsequent bleeding.
- The heat also has another damaging effect, as summers tend to intensify allergy, and an allergic reaction can cause nosebleeds.
Washing your nose with cool water and avoiding being subjected to direct sunlight may help to prevent nosebleeds. If you wish to discuss about any specific problem, you can consult an Ent Specialist.
