Common cold: The common cold is an infection caused by a virus known as 'rhinovirus' affecting your nose and throat (upper respiratory tract). Children younger than six years of age are at the most significant risk of colds, but healthy adults can also be affected to have 2-3 colds annually. In most cases, cold symptoms are recovered within a week or ten days. However, symptoms might last longer in people who smoke or are exposed to allergens like dust, pollutants, etc. Common cold symptoms might include stuffy or runny nose, sore throat, cough, congestion, mild body pain or a mild headache, sneezing, low-grade fever, and feeling unwell (malaise). In some cases, the discharge from your nose may become thicker and yellow or green, which does not indicate a bacterial infection. If you observe these symptoms, immediately contact your doctor.

Allergies: This is a condition that occurs when allergy-causing agents known as 'allergens' attacks our body, thereby causing symptoms like redness, stuffy nose, watery eyes, excess mucus formation, airways irritation, itchy and watery nasal passage/throat. During the allergic condition, our body secretes a lot of chemical messengers called 'histamines', which in turn cause all these allergic symptoms. Allergies can be caused due to various chemicals, air pollutants, dust, pollen grains of plants, pet danders, hairs and multiple medicines.
