Is there a link between aromas and having a tight neck and breathing issues?

I know someone who's experiencing that and I wanted to know more if there is some linkage between aromas (i.e. minty aroma from toothpaste and fragrance from shampoos) and having a tightening effect around the neck region and having heavy breathing.

Could someone provide me with their opinions and or credible sources? Solutions?

Could it be that the person I know is just overthinking (i.e. psychologically-induced panic attacks)?

This person is a young adult, female, and moderately active. Recently, she's also been told to avoid wheat in terms of dietary needs.

Are these conditions somehow affecting her immune system or are they two separate issues? If so, any solutions or feedback is greatly appreciated.

It's just baffling to me and I really want to help her get better.
