Smell Sensitivity Linked to Cough

Study Calls Chemical Sensitivity and Cough Sensitivity Combo A New Disorder

June 13, 2006(WebMD) People who are sensitive to odors also might cough more

easily than others.

 

A new study shows a physical link between chemical sensitivity — or odor

intolerance — and increased cough sensitivity, a condition the researchers

say

should be a newly named disorder.

 

The Swedish scientists included Ã…ke Johansson, M.D., from the department of

lung medicine at Central Hospital in Skövde. They wanted to find out exactly

how chemical sensitivity and cough sensitivity are linked because many

patients who are sensitive to smells also report a variety of nonspecific

symptoms

including " cough " and " pressure across the chest. "

 

To get more specific, the researchers performed capsaicin inhalation tests

on 103 people. Capsaicin is an ingredient in red pepper; when inhaled it can

cause cough by stimulating sensory nerve endings. The number of times a person

coughed during the 10-minute test determined a positive or negative result.

Sixteen people had a positive result.

 

The researchers found patients with odor intolerance " react more strongly …

to provocation with capsaicin inhalation " — 80 percent of those with a

positive inhalation test also had a positive chemical sensitivity score.

 

Study participants' chemical sensitivity scores had been determined by how

they ranked scenarios in a questionnaire, including:

 

# I am easily alerted by odorous/pungent substances.

# At movies, other persons' perfume and aftershave disturb me.

# In public places, I do not mind some smell of cigarette smoke.

# I would not mind living in an apartment that has a weak smell.

 

Because the researchers " regard the capsaicin inhalation provocation as a

fairly objective test, " they say the cough response in odor-sensitive people is

a " physiologically demonstrable disorder. " They call it " airway sensory

hyperreactivity, " or SHR.

 

 

 

The study appears in the June issue of CHEST, the journal of the American

College of Chest Physicians.

Moderator's Note: I think the ideal solution is to make our own food from

scratch. Then we know the ingredients, the quality, etc. because we made it.

" Capsaicin is an ingredient in red pepper "

 

And why is this even being put into our foods? Foods tasted fine

without it! Don't they know people with allergies will react to this

ingredient. I think they know but don't care.
