Types of Allergens

Types of Allergens
There are various types of allergens which could trigger an allergic reaction which require medical attention by a health care provider or other physician. Following are the top 6 most common types of allergens:

Ragweed:

This is named after the ragged shape of its leaves. This is one of the most common plant allergen. A single ragweed plant can produce millions of pollen grains in a day and billions during their growth. Unlike other seasonal allergens, this ragweed starts pollinating in the late summer, that is around mid August and it continues till heavy frost. 75% of people who suffer from pollen allergy are allergic to ragweed also. People with allergic reaction to ragweed may also develop symptoms if they eat banana and cantaloupe. Sunflower seeds, honey and chamomile tea which contain pollen may rarely trigger intense reactions, like anaphylactic shock.

Dust mites:

Dust mites are ugly are microscopic organs. These may cause allergies round the year. According to researches, nearly 20 million Americans suffer from this allergic reaction. These can easily adapt to the humidity and temperature of a typical home and can survive on tiny skin flakes of a person which he sheds every day. Typically an adult can shed enough flakes for feeding a million dust mites.

A protein present in the waste product of dust mite is the primary cause of dust mite allergy. A single dust time can produce 200 times its body weight in its waste. Bedroom is the primary repository for dust mites.

Mold:

Molds such as mildew are fungi that reproduce by releasing spores into atmosphere. Mold allergies are common in mid summer to fall, which are caused by molds which grow on the rotting logs, composts piles and falling leaves. Symptoms of mold allergy may develop round the year.

Animal Dander:

Even though most people with pet allergies think that animal fur is the main culprit, it is not. According to the researches, proteins are the allergens which are secreted by the oil glands in the skin of the pet and also shed in the dander. Proteins in urine and saliva are potent allergens.if a substance that carries protein dries, it becomes an airborne. Cats cause more allergies than the dogs. Proteins in the pet’s urine like rats, mice, guinea pigs and gerbils can also trigger allergic reactions.

Allergic reactions of pets may not occur immediately, in fact it takes about 2 or more years to develop symptoms. Furniture, air and carpet can harbor allergens for several months even after removing pet from house. If you are allergic to pets, make sure that the previous owners or tenants didn’t have pets.

Tree Pollen:

Nearly 100 varieties of trees cause allergic reaction. The most common culprits include willow, walnut, wattle, Ti, poplar, plane, pine, olive, oak, mulberry, myrtle, maple, hickory, heath, hazel, elm, Western red cedar, Japanese cedar, cypress, chestnut, birch, beech, ash and alder.

In tree season, try to keep the windows and ventilators closed and use air conditioners instead of attic fans or windows. Many people are allergic to a particular species, while some people are allergic to several members of a family. Some of them include:

  • Cedar
  • Juniper
  • Oak
  • Birch
  • Beech
  • Alder

While planting trees, make sure that you choose varieties that do not cause allergies. Some of them include: redwood trees, redbud, plum, pear, palm, fir, fig, dogwood, crape myrtle and catalpa.

Grass Pollen:

Lacking the beautiful and showy flowers which attract insects for pollinating them. Grass depends on wind for spreading the pollen. Although 1,200 or species of grass in the North America, only 20 grasses cause allergies. Following are the most common types of grass allergies:

  • Timothy grass
  • June grass
  • Sweet vernal grass
  • Johnson grass
  • Salt grass
  • Fescue grass
  • Redtop grass
  • Bermuda grass
  • Perennial rye grass

If your lawn contains one or more of these grasses, you must wear a mask or have some other person to mow the lawn for reducing the amount of pollen you inhale. You must also ensure that you mow the grass very short such that you prevent seeds. You must also choose other types of grasses for reducing the discomfort caused by these grasses during the summer season. You must consider doing outdoor activities late in the evening, when the concentrations of pollen are low and after a short rain or when there is mild breeze. After mowing, you must take a shower and change the outfits and leave the shoes at door for reducing the contact with the clinging pollen.
