Seasonal allergies occur at certain periods of the year and will be a distress to many people who are allergic. Given below are some of the causes and symptoms of severe seasonal allergy.
Seasonal allergy caused by pollen grains
Many plants, weeds, shrubs and trees release pollen grains for pollination. They may release pollens at various seasons. For this reason, seasonal allergies may be lasting throughout the year in some patients. Most plants release their pollen grains during spring and summer. Pollens are miniature pods released by the plants and trees for pollination and procreation. Pollens may be airborne or insect carried. The human body parts where these pollens cause allergy are the eyes, inside of the nose, lungs and the skin.
Symptoms of seasonal allergy caused by pollens
Pollen grains, when they come into contact with the nose cause runny nose, nasal blockage, breathing difficulty, sneezing, swelling of the nose, wheezing and allergic rhinitis. An infected nose will most probably look reddish. Sometimes a severe nose infection can also spread to the ear. This usually happens in children. Sinus infection can get severe and the person will suffer from headaches as a result.
If a person has asthma, it will increase in severity. When pollens come into contact with the eyes they can cause allergic conjunctivitis which is an allergic condition of the eyelid that covers the retina. The person will have severe watery eyes. He/she also has red-shot eyes and will feel itchy in the eyes. The eyes will also seem reddish, similar in appearance to an infected nose.
Seasonal Allergy Symptoms
Pollens grains can also cause itchiness inside the upper layer of the mouth. The throat will also feel itchy. Some people may complain of coughing. Overall the person might seem irritated. They may also feel less hungry. They will also have difficulty falling asleep.
The skin may turn reddish when pollen lands on allergic skin. Some people may even develop eczema.
Seasonal allergy caused by dust
The amount of dust increases during summer season causing an increase in the suffering of those who are prone to such seasonal changes. Dust remains airborne for most of the summer as the heat and sunshine causes loose earth particles to become airborne. Besides soil, dust also contains natural and artificial fiber, animal dander, dust mites, mould spores, natural and artificial debris, human epidermal secretions, food flecks, insect parts and insect faeces. All these can cause allergic reactions in people prone to allergy.
Symptoms of seasonal allergy caused by dust
Runny nose is the first sign that appears. Other symptoms include sneezing, wheezing and difficult in breathing or rapid breathing. Severe coughing that can last more than a few seconds is almost unavoidable. Eyes will start watering in allergic people. Some people tend to scratch their skin repeatedly which causes redness. And they may feel burning sensation in their skin.
Seasonal allergy caused by nasal polyps
Nasal polyps occur when the inner lining of the nose which contains mucous, gets infected repeatedly. The problem of nasal polyps can get aggravated when allergens like pollen grains and dust stimulate the mucous lining or the inflammatory cells on the inner layer of the nose. This causes swelling of the nasal polyps
Symptoms of seasonal allergy caused by nasal polyps
When stimulated or irritated the nasal polyps swell and increase in size blocking the nose. This forces the patient to breath through the mouth. The person also experiences sneezing and runny nose. When these factors combine, the affected person suffers from a reduction in his/her sense of smell which is accompanied by a reduction in the sense of taste.
Seasonal allergy caused by pollution
Allergens like pollen grains and dust induce allergic asthma with the onset of a seasonal change. Similarly polluted air also plays a role. When the air is thick with vehicle exhaust as well as other forms of air pollution during colder months, it excites the allergic areas in the nose. This leads to allergic asthma. This form of asthma is called Extrinsic Asthma.
Symptoms of seasonal allergy caused by pollution
When a person suffers from allergic asthma, he will have shortness of breath, rapid breathing, wheezing, anxiety, bluishness of the face mostly the lips, frequent coughing and a feeling of the tightening of the chest accompanied with a feeling of pain.
