Allergies can be from both the environment or from food. The most common causes of environmental allergies are pollens, but house dust, mites, molds, and tobacco smoke are some other common irritants. Allergies can develop at any age. Irritated eyes, stuffy head, sneezing, headache and drowsiness are allergy symptoms that can many times mimic those of the common cold. To help tell the difference, consider the duration of each of your symptoms.
Colds tend to last seven to ten days, while allergies can go on for weeks.
In addition, look at the type of discharge you produce, many times with allergies the mucus is clear and watery, while it tends to be thick and discolored for colds. Allergists can help you discover what types of things are triggering your allergy symptoms and help you avoid further exposure. Over the counter products can ease symptoms, but many people find prescription medicines more effective and less likely to produce unwanted side effects such as drowsiness. People with allergies tend to be more prone to the effects of respiratory infections, so you will want to see an allergist if you have persistent nasal congestion, a recurrent cough, wheezing, chest congestion, or repeated sinus or ear infections. There are also many herbs that can offer relief from allergies.
