Autumn Cold Allergies Causes
With the coming of autumn cold allergies are triggered due to an increase in the atmosphere of the most troublesome allergens, ie, fungi and molds, said Vivian Moncayo, allergist Angeles Lomas Hospital pediatrician. Rain and humidity of summer used to clean the air of pollen particles in autumn favor the appearance of mold spores, which increase its circulation both in the environment inside the houses, as these remain longer closed to conserve heat, and the air inside of the house is constantly renewed by the use of heating and air conditioning, said in a statement.
He says that for fungi and molds to replicate need to be in a wet environment with a small amount of sunlight. The conditions that occur at this time are ideal for the reproduction of fungal spores within and outside the home. He says that during the early morning is when most spores multiply, so that allergy symptoms may occur with greater intensity at night. Thus, people who are allergic to molds tend to wake more often at night with a stuffy nose, he says. Allergens cause an inflammatory reaction with release of substances such as histamine, which cause congestion, sneezing, itching and runny nose. Most affected are children, and that lack of sleep and rest they need can affect daily functioning, as well as more susceptible to infections.
