Recent research has shown a correlation between children and adults who have allergies/asthma and also have anxiety disorders. It’s not known if one problem causes the other, or if perhaps they have a similar underlying cause, or if perhaps simply not feeling well adds to one’s stress level.
In my clinical practice, I have observed this relationship for a long time. I can’t explain it either, but I do have some theories. What I notice is that when the body over-reacts to things (in this case, one over-reacts to an “allergen” like pollen, dust or pets), the mind is often over-reactive as well. It fits with my belief that mind and body are not really separate things, just different facets of the whole. As to what causes this correlation, I think inflammation is a likely culprit. After all, if the body has inflammation, so does the brain, and recent theories suggest that inflammation may be a common cause of depression and anxiety. Whichever comes first, I think that the antidote is to calm the system, to add stabilizing measures so that there is less reactivity to any underlying trigger.
