Just As I Thought…

And just as millions of allergy sufferers and physicians have thought for years.

A new study shows that even slight stress and anxiety can substantially worsen a person’s allergic reaction to some routine allergens.

Moreover, the added impact of stress and anxiety seem to linger, causing the second day of a stressed person’s allergy attack to be much worse.  [...]

“The wheals on a person who was moderately anxious because of the experiment were 75 percent larger after the experiment, compared to that same person’s response on the day when they were not stressed,” Kiecolt-Glaser said, signifying a stronger reaction.

“But people who were highly anxious had wheals that were twice as big after they were stressed compared to their response when they were not stressed.  Moreover, these same people were four times more likely to have a stronger reaction to the skin test one day later after the stress,” she said.

This next-day change – labeled a “late-phase reaction” – is important because it signals an ongoing and strengthening response to the allergens, and even suggests that sufferers may react strongly to other stimuli that previously hadn’t caused them to develop an allergic reaction.  [...]

The researchers also measured levels of stress hormones called catecholamines and they were elevated as well.

He suggests that the raised levels of these compounds [including interleukin-6 and other cytokines] are to blame for the residual effects seen in the late-phase reaction.

“What’s interesting about this is that it shows that being stressed can cause a person’s allergies to worsen the next day,” she explained.

“This is clinically important for patients since most of what we do to treat allergies is to take antihistimines to control the symptoms – runny nose, watery, itchy eyes, and congestion.

“Antihistimines don’t deal with those symptoms on the next day.
