The Top Sinus Allergy Causes

Sinus cavities, though they are located in the head, open up in the nasal passages for free exchange of air and mucus. This is how the sinus allergy causes come into play, enter the nasal cavity and often cause sinusitis.

Sinus allergy causes can be many and varied. It can range from the pollen of flowers, dust, dirt, pollution etc. These sinus allergy cause the nasal cavity to become blocked. When the mucus cannot flow freely anymore, it becomes stuck inside the nasal cavity and that becomes a perfect breeding ground for allergies.

Pollen, a powdery substance released in the air by flowers is the most common cause for allergies. All sinus allergies causes center around the pollen and therefore spring is the worse time for sufferers. As the air is unusually dry in spring and the pollination season also starts, the pollen is carried easily by the dry breeze. This way it enters the body with the air we breathe. For those who are prone to sinus allergies the trouble begins at this stage. The body perceives of these sinus allergy causes as harmful substances and produces histamine to tackle their effects. The histamine causes itching in the eyes and a runny nose.

Some people have been seen to come down with allergies when they come in contact with animals like dogs or cats. For such individuals the sinus allergy causes lie in the micro-organisms that are present in the fur of these animals. Again it's not that the sinus allergy causes are common for everyone, while some people fall seriously unwell when exposed to pollen or animals, others do not feel a thing. However for people who have an allergy to animal furs, the body reacts in the same way as it does with pollen and a case of sinusitis is soon in full swing.

Sinus allergy causes, whether it is pollen, animal fur, mold or dust is in most cases within ones sphere of control. Though there is not much that you can do to keep the pollen from coming in with the air, repeatedly cleaning the house often rids it of the other potential causes like mold and dust. Environmental triggers are the sinus allergy causes therefore try as much as possible to keep control on them. As long as the immediate surroundings of a person prone to sinusitis are clean, there are fewer chances of sinus allergy causes wrecking havoc on his or her system.

The answer to the riddle of why certain sinus allergy causes harm some people while leaving others unaffected lies in the hereditary make up of people. It is generally seen that people whose parents suffered from allergy of a certain type are predisposed towards them. Even unlikely sources like milk and milk products act as sinus allergy causes in some people with such hereditary make-up and can make them sick.

Once the diagnosis of what causes allergy is a person is done effectively, allergy causes can be controlled or even removed to restore normal breathing and life to the sufferers.
