Question

Por que o nosso nariz fica entupido quando estamos resfriados?

Answer 1

why does our nose get stuffy when we have a cold

Answer:

Due to dilation of blood vessels in the sinuses of the nose

Explanation:

Often times, we think our nose gets stuffed up due to the excess mucus in times of cold but it is not always so.

We get stuffed due to the body's homeostasis, a drive to internally control and balance the outside environment.

• During cold, blood vessels dilate so as to allow for more inflow of blood.
• Incoming blood brings in more heat to the body parts.
