A member asked:

Why would i get dizzy and a headache from blowing my nose?

A doctor has provided 1 answer

Increased head press: Blowing your nose will cause a sudden rise in pressure in the head or "intracranial" pressure. This then, decreases circulating blood volume to the brain as well as stretches its coverings called the "meninges" leading to dizziness and headaches respectively. Or, you may just have a cold! to reduce your discomfort try either blowing your nose with mouth open or do one nostril at a time ; gently.
