fever

Snot is not pleasant, specially if it runs down your face. But it is also very useful. It helps us to not get sick.

Have you ever had a runny nose?

Sometimes our ears hurt. Have you ever had earache? It’s very painful, isn’t it? And somebody’s bound to have said at some time that you had otitis.

Otitis is an infection caused by a virus or bacteria that gets into the middle ear from the nose or throat via the Eustachian tube. However, otitis can also affect the inner ear.

Your body temperature is usually between 36.5 and 37 degrees centigrade. When this temperature goes over 37.8º or a bit more, you have a fever.

Our body is at a temperature between 35.8ºC and 37.2ºC. Sometimes, this temperature goes up. When it goes above 37.8ºC, we say that we have a fever.

Snot is a thick, gooey, sticky substance produced in some parts of our body. Poses no risk to your health, but it may be annoying.
