Indoor allergens

Most people with hay fever, asthma or any other outdoor allergic reactions think their home as a heaven as they can escape from allergens. Unfortunately, apartments and houses are harbors for allergens. The inside of the home traps allergens and makes them impossible to avoid them.

  • Although most allergens in the environment trigger symptoms of allergies, dust in the home is the main cause of indoor allergies. What exactly is house dust?
    • House dust varies based on the age and type of the home, the humidity and temperature in home, what all you store in the home, everything ranging from food, clothes to furniture and who lives in your home that is pet, animal, human and plant.
    • Some dust is always present in home irrespective of how thoroughly or how often you clean the house.
    • House dust is an air borne mixture which contains tiny particles of plant material from outdoors and indoors and soil, particles of animal and human dander or skin and hair, mold spores, food particles, fabric fibers, dust mites and insect fragments and their waste and other debris.
    • Although most substances in dust cause allergic reactions, the most important indoor allergens include molds, cockroaches, pet dander and dust mites.
  • Apart from seasonal allergies like hay fever, these indoor allergies can last throughout the year. Indoor allergens can worsen or provoke asthma symptoms, based on the sensitivity of a person.
    • Indoor allergies may worsen in late summers when dust mites are at high amounts in air.
    • Symptoms of allergies are worse during winters when windows are closed and thereby people are shut in with allergens.
    • Opening the windows at nights when mold and outdoor pollen count is high can worsen asthma or allergy symptoms as they settle down in the house.
    • If a person is sensitive to indoor allergens, he will suffer from symptoms until the person is exposed to allergens.
  • Sensitivity to allergens is common and can occur at any age. This is rarely observed in children below 5 years. Elderly people and children in early school experience allergic rhinitis.
