Allergies



There are many things you can be allergic to - affecting your physical and emotional bodies. You can be allergic to people, places, and things, and may not recognize what they are. It's all about trial and error and finding out exactly what's creating symptoms in your body. There are former allergens - and now as we are discovering each year - new ones as the environment changes. It is also important to know the difference between allergies and colds or flu. In the world of self-help and awareness, it would seem that most of us are becoming therapists and doctors as we search for ways to improve our lives.

What are you allergic to? It's that time of the year allergies - both old and new - reshape people's daily lives and sleeping patterns.

Out in Gilbert, Arizona my daughter Tracy reports local residents are faced with this situation ... Many residents have relocated there from other parts of the country bringing various trees and plants along to make it feel more like home than the desert. Pollen from those plants now conflict with local plant life and create all sorts of new allergens.

My neighbor Jack, 75, told me that he no longer feels comfortable taking his morning walk around the park across the street because of the pollens.




Common Symptoms of Allergies







Allergy is a hypersensitivity disorder of the immune system. Allergic reactions occur to normally harmless environmental substances known as allergens; these reactions are acquired, predictable, and rapid. Strictly, allergy is one of four forms of hypersensitivity and is called type I (or immediate) hypersensitivity.

It is characterized by excessive activation of certain white blood cells called mast cells and basophils by a type of antibody known as IgE, resulting in an extreme inflammatory response. Common allergic reactions include eczema, hives, hay fever, asthma attacks, food allergies, and reactions to the venom of stinging insects such as wasps and bees.

Mild allergies like hay fever are highly prevalent in the human population and cause symptoms such as allergic conjunctivitis, itchiness, and runny nose. Allergies can play a major role in conditions such as asthma. In some people, severe allergies to environmental or dietary allergens or to medication may result in life-threatening anaphylactic reactions.

A variety of tests now exist to diagnose allergic conditions; these include testing the skin for responses to known allergens or analyzing the blood for the presence and levels of allergen-specific IgE. Treatments for allergies include allergen avoidance, use of anti-histamines, steroids or other oral medications, immunotherapy to desensitize the response to allergen, and targeted therapy.

DNA markers link season of birth, allergy risk   Science Daily - March 21, 2016

The season a person is born in influences a wide range of things: from risk of allergic disease, to height and lifespan. Yet little is known about how a one-time exposure like the season of birth has such lasting effects. Researchers have now discovered specific markers on DNA that link the season of birth to risk of allergy in later life.

  Where do allergies come from?   CNN - March 26, 2013

Scientists know what causes allergies. When particles of pollen, pet dander or certain types of food enter our bodies, they're called antigens. If your body has a sensitivity to that particle, it mistakes the harmless element for a dangerous invader, according to the American Academy of Allergy, Asthma and Immunology. The particle then becomes what we call an allergen, although a sensitivity to a substance alone doesn't guarantee you will develop an allergy. Allergens cause your body to produce Immunoglobulin E, or IgE, antibodies. Antibodies are used to identify and destroy dangerous invaders. Unfortunately, IgE antibodies also release histamine and other chemicals that can create an allergic reaction. But what causes one person to become sensitive to these indiscriminate antigens floating through the air, while another sails through life with dry eyes and clear sinuses? Scientists aren't exactly sure, but they have a few ideas.
