Allergy is a hyperactive response by the immune system to harmless substances like dust, pollen, etc. Most common symptoms of allergy are sneezing, runny nose, cough, itchy eyes, post nasal drip, swollen eyelids, dark circles under the eyes, etc.
What Causes Allergy?
Allergy is not caused due to virus as the common cold is. The allergens like pollen, dust cause the immune system of the body to release Immunoglobulin E and histamines into the nasal passage which causes the allergy symptoms like runny nose, sneezing, etc. Some people are also allergic to food or certain medications. Environmental conditions, pollution are the key factors that cause allergic reaction.
Although allergy is common in children, people can develop allergies at any age. A person is more likely to develop allergy if their family has prior history of allergy in parents or siblings.It is better to identify what causes the allergy and take steps to avoid them. Allergies caused due to pollen or dust can be avoided by cleaning the house frequently, washing your hair often as some pollen might stick to your hair, cleaning the pets often, using air purifiers in the house.
There Are Some Home Remedies For Allergy Cold And Cough:
Saline solution helps thin the mucus in nasal passage and also helps remove the irritant responsible for the allergic reaction. Put a drop of nasal saline solution in each nostril 2 or 3 times a day. Repeat if necessary.
Onion And Garlic:
Onion and Garlic contain quercetin, a compound that may prevent the body from producing histamine. During an allergic reaction, the immune system of our body releases a chemical called histamine, which causes mucus secretion and other allergic effects.
Green tea contains an antioxidant called EGCG that reduces production of histamine and immunoglobulin E that causes allergy symptoms. Take 2 to 3 cups of green tea every day for relief.
Vitamin C is a natural antihistamine. Citrus fruits, papaya, strawberries, pineapple are excellent sources of vitamin C. The normal dosage of Vitamin C depends on age and health condition. It is better to consult with a doctor to decide the right dosage.
