Increased sensitivity to any stimulus is increasingly observed among children and adults. The list of allergens is very large: to determine which one will provoke a negative reaction from the body, you can use skin tests or a blood test. Among the substances that cause allergies, there are five of the most common.

Watery eyes, frequent sneezing and nasal congestion are vivid symptoms of the body's reaction to a weed that blooms in summer or early autumn. The plant is called ragweed, and allergies to it are called hay fever.

A weed with ragged leaves is capable of rapid reproduction. Ragweed is a common source of allergies, especially in children. A single plant can produce up to a million pollen grains per day, or up to a billion during the growing season. The problem is aggravated by the fact that allergenic particles are carried by the wind over long distances: researchers found ragweed pollen several hundred kilometers from the growing zone.

Dust mites

The following common allergens come from the arachnid class. These are microscopic organisms that live in colonies. Dust mites are among the main sources of year-round allergies. Ideally adapted to the temperature and humidity of the home, microorganisms survive on the tiny flakes of skin that people shed every day. One adult is able to "feed" a million individuals per day.

Allergy symptoms are not triggered by the mite itself, but by the protein in the waste. One individual is capable of producing 200 times its body weight. The most suitable place in the house for dust mites is the bedroom, since skin particles remain on the bedding.

Methods for dealing with ticks:

  • Cover the beds and pillows with dust covers with zippers.
  • Wash sheets at a temperature of at least 60 ° C.
  • Equip the vacuum cleaner with special filters. Treat bedding carefully. Vacuum each mattress for at least 20 minutes to minimize allergic reactions to dust mites.
  • Remove items from the room that collect a lot of dust - stuffed animals, heavy curtains, blankets, carpets.

For allergy sufferers, cats, hamsters, dogs or their fur are not dangerous. Substances secreted by the sebaceous glands of domestic animals pose a threat. These components first fall on the wool, from there - on the mucous membranes, human skin. Proteins in the saliva and urine of animals are also considered strong allergens.

Allergies are more often caused by cats that are a lot indoors and constantly lick themselves. Dogs are also a threat, but to a lesser extent. Allergic reactions are caused by proteins in the urine of domestic rodents. These can be guinea pigs, gerbils, mice or rats.


The next common allergens are fungi

What to do to reduce discomfort:

  • Wear a face shield when mowing lawns or raking up rotten leaves.
  • Replace or dry damp mats regularly. Treat surfaces monthly with a solution of household bleach.
  • Keep the humidity in the basement low by raising the temperature.
  • Buy an air conditioner
  • Clean the rubber bands and water drain systems of the refrigerator with detergents. Take out the trash and wash the bucket regularly.


Among plants, it is not only ragweed that causes allergy. The pollen is produced by various grasses and trees, and then spread by the wind.

Dangerous allergens:






Feather grass






Mother and stepmother



When these plants and trees are in bloom, keep windows tightly closed and use an air conditioner
