Causes of Allergy.
Allergy occurs when the immune system of a person reacts to substances that are harmless to most people in the environment, known as allergens, these substances are found in dust mites, pets, pollen, insects, ticks, moulds, foods, and some medicines.
Allergies actually occur when your body’s immune system reacts to a foreign substance like pollen, bee venom, or pet dander, or a food that most people don’t react to, your immune system produces antimicrobial substances, your immune system makes antibodies when you have allergies.
That actually identify a specific allergen as harmful, even if it’s not, the reaction of your immune system can inflame your skin, sinuses, airways, or digestive system when you come into contact with the allergen.
Symptoms of allergy include itchy eyes and skin, sneezing, congestion of the nose, wheezing, and rash. Seasonal allergies are caused by grass, weed, tree or mold pollen. Allergies to cat and dog dander are common, allergies to foods include peanut or milk.
While allergies may develop at any age, there is a genetic risk of developing allergies. It’s related to your allergy family history. If none of the parents are allergic, allergy chances are around 15%, if one parent is allergic, the risk increases to 30% and if both are allergic, the risk exceeds 60%.

Trees are responsible for most seasonal allergies in the springtime. birch is one of the most common offenders in northern latitudes, reacting to its pollen by many people with hay fever. cedar, alder, horse chestnut, willow, and poplar are other allergic trees in North America, pollen is the largest spring allergy trigger,
These tiny grains are released into the air by trees, grasses and weeds to fertilize other plants, they send the haywire of the body’s defenses when they get into the nose of someone who is allergic.
There is no cure, but you can take steps from medication to household habits to curb springtime allergies.
Summer allergies are usually caused by grass and weed pollen.
Spring’s over, but you’re still stopped, sniffing, and sneezing, pollen is the biggest culprit, trees are usually made by late spring with their pollen-fest. this leaves grasses and weeds to cause allergies in the summer.
The largest allergy triggers in fall are ragweed, mold and dust mites. ragweed is the Fall’s largest allergy trigger. Although it usually begins to release pollen in August with cool nights and hot days, it can last through September and October, approximately 75 percent of people allergic to spring plants also have ragweed reactions.
If you have indoor allergies such as mold and dust mites, if you spend more time inside, you may notice more symptoms during the winter.
