Question

Explain why it is sometimes difficult to smell things when you have stuffy nose. Need answers asap​

Answer 1

Because the air or the smell won’t come inside if its a stuffy nose

Answer 2

When one has a cold, flu or sinusitis, there is swelling and a lot more mucous in the nose. The mucous and swelling in the nose prevents the smell (odorant) from reaching the top of the nasal cavity. Hence the smell never reaches the smell nerves and the nerves are not stimulated.
