Causes

 Over inhalation of dry air. This dries the blood vessels in the

nostrils and they break.

 Over blowing or one’s nose with cold. This over strains the

blood vessels in the nostrils and they break.

 Taking foods one’s body is allergic to.

 Taking medications for a long time (aspirin, garlic, ginger). It

prevents normal blood clotting and instead thins the blood.

First Aid

 Pinch the upper side of the nostrils.

 Encourage the victim to breathe through the mouth to pre-

vent over straining the blood vessels. ►

 Keep the head of the victim higher than the level of the

heart.

 Put ice wrapped in a towel on the nose and chick to make

the lining of blood vessels in the nostrils moist.

Do not make the causality to lean back because it allows blood

to flow back to the throat which may cause vomiting or irrita-

tion.

Prevention

 Keeping the nostrils moist

en the lining of blood vessels.
