9. Atmospheric Pressure Changes
Sinuses are air-filled cavity located in the head. So when the air pressure drops, the air that is inside the sinuses will want to exit, which triggers pain in the nose.
Under normal conditions, the nasal passages will open up allowing the air to freely move in and out in the event of air pressure changes. However, if there is already an issue with the upper respiratory system or sinus cavities, then this can be a problem. For those with pre-existing sinus disease, any change in the atmospheric pressure can make the condition even worse and this can lead to pain in the sinus.
