Why do Noses bleed?

The nose is the organ for the sense of smell. The nose is the entry point of air leading towards the respiratory system. Although inhaling can be an involuntary act, the ability to smell the inhaled air is the primary function of the nose. The nose has associated structures that facilitates and controls the amount of air to be inhaled. Along with the hairs found within the membranes, just beyond the nostrils, it also acts as a barrier to any unwanted particles or specimens that may potentially enter and harm the lungs. As with the other parts, the nose is in its anatomical position with the desired structure to function fairly with the other parts of the body.

The most common problem encountered with the nose is term epistaxis or most often called, nosebleed. Nosebleeds are common primarily because the nose is rich with blood vessels. Because it aids in humidifying the air that passes through the nose, these blood vessels are located close to the surface. Considering its anatomical location, the nose is always at high risk for trauma or injury that may eventually lead the nose to bleed. Another reason for the nose to bleed is because it is too dry. Dryness occurs when there is an inadequate amount of heat and the ability of air to form moist is not possible. Frequent dryness leads a person to constantly prick one’s nose because of its itchiness. When these two actions are done frequently, a possible nose bleed can happen. With higher recorded incidences during cold seasons, presence of predisposing factors such as hypertension, allergic reactions and infection can be the reason why noses do bleed.

Though many may not take nosebleeds seriously, medical attention is still needed especially if it happens frequently and unexpectedly.
