Hay fever-what is it?
Hay fever is also known as allergic rhinitis. It causes cold like signs and symptoms including a runny nose, condition, itchy eyes, sneezing and sinus pressure. However, even though there are different similarities with common cold, it is not caused by a virus. It is generally happens because of an allergic response to allergens like dust mites, pollen or a pet dander. It not only creates a miserable condition for you, but it also drastically reduces your performance and hampers normal day to day life. It is possible to avoid the triggers that cause hay fever and there are treatments available for it.
Some of the most common signs and symptoms of hay fever are:
- Runny nose and nasal congestion
- Watery, itchy, red eyes (allergic conjunctivitis)
- Itchy nose, roof of mouth or throat
- Swollen, blue-colored skin under the eyes (allergic shiners)
- Postnasal drip
Seasonal factors and triggers
Hay fever signs and symptoms may start or they can worsen at a specific time of year. That is generally done by different types of triggers which cause this problem. Such triggers may include-
- Tree pollen. It is very common during early spring.
- Grass pollen. Grass pollen is common during late spring and summer.
- Ragweed pollen. It is common in fall.
- Dust mites, cockroaches and pet dander. These triggers can be perennial and they can cause disturbance throughout the year. Symptoms caused by dander might worsen in winter, because at that time keep your houses closed.
- Fungi and mold spores from indoor and outdoor can both be seasonal and perennial.
Causes of hay fever
You suffer from (allergic rhinitis) because the immune system starts viewing harmless triggers like inhaled pollen or other allergens as dangerous substances which are invading the body. As a result of that your system overreacts and it triggers your body to release chemicals like histamine and leukotrienes. These substances can inflame the lining of your nasal passages, sinuses and eyelids and can produce the symptoms associated with hay fever.
The symptoms that you see during a hay fever attack are meant to protect your body by expelling the allergen or trapping it, which is done by swelling body areas so that the allergen cannot enter your body. Congestion in the vein in the linings of your sinuses happens and because of that dark circles which are also known as allergic shiners may appear under the eyes.
People who suffer from perennial allergic rhinitis, this may happen throughout the year. If the swelling of your nasal membranes close your sinus drainage openings it may cause sinusitis. Sometimes rhinitis is also associated with nasal polyps which are small and noncancerous growths, and also nosebleeds as they may occur during a hay fever attack.
In most cases, hay fever is often an inherited trait and so it is genetically determined. Most of the patients who suffer from this problem have a parent or sibling who also has allergies. If you already suffer from asthma or eczema, you're more likely to suffer from hay fever.
A fever can result in several other complications. These complications include reduced quality of life, poor sleep, worsening asthma, sinusitis, ear infection in child and adults. Your overall life quality will be drastically affected by hay fever and the symptoms thereby causing other problems as well.
