An allergy is a sensitivity disorder of the human's immune system. Allergic reactions occur when the person's immune system responds to normally harmless substances in the environment. You may notice some symptoms whenever you're immune will respond to allergens- the substances that cause allergy.

There are various types of allergy. You may catch allergy by dust or pollutants and even by eating certain foods that do not suit you. Your body may take some time to adapt those foods.  You may notice light fever, itchiness on skin, redness on skin, coughing, sneezing, red eyes and even eczema. Insects and wasps may also cause allergy.

Asthma is a chronic disease that is also caused by allergy. It occurs when your immune system is not strong enough to tackle the foreign dust particles coming in contact with the body.

Allergies can also be hereditary. They may also erupt due to gender and race. But hereditary allergies play the most significant role.

Asthma is a disorder that causes the airways of lungs to swell and narrow. It leads to shortness of breath, chest tightness and coughing. Allergens play a major role in triggering up asthma.

Common asthma triggers include:

• Animals (pet hair);

• Dust particles;

• Changes in weather (most often cold weather)

• Chemicals in the air or in food;

• Exercise;

• Mold;

• Pollen;

• Respiratory infections, such as the common cold;

• Strong emotions (stress);

• Tobacco smoke.
