The Ohio State University does a study to show how stress affects allergies.

Researchers set out to show what happens to hay fever sufferers under stress. First they exposed them to the allergens.
Clinical Psychologist, Janice Kiecolt Glaser, PhD explains what happened next, " To stress these people what we did was bring them into the laboratory and tell them they had five minutes to prepare a speech about why they were the best person for a particular job and then they delivered it to a panel of two or three people."

Researchers compared the size of the wheals --or hive-like reactions-- before, during and after stress. The size of the wheals didn't change with people who were not stressed, but if people were moderately anxious it was about 75% bigger. If they were really anxious, it was about 200% bigger. It doubled in size.
Researchers say the impact can last.

According to Ronald Glaser, PhD, professor of molecular virology, immunology and medical genetics, "Stress affects allergies at least two different ways. There's an early event, acute and up to 24 hours, or late phase response."

It's well documented that stress impacts the immune system.

As a Chiropractor I strongly believe the impact "STRESS" can have on peoples bodies. Chiropractors adjust or manipulate the spine to remove stress from the nervous system and in turn restore joint mechanics, flexiblity, decrease pain, and improve nervous system function. For those that disagree that Chiropractors can improve nervous system function, well look at this article and think if we can remove stress from the spine will that not inturn remove those stresses from our nerves that come down through and out the spine? Just as this article suggest stress affects many conditions that cause or exacerbate 80% of illness according to the AMA.
