Allergies are caused by over reaction of our body to different stimuli. But what are the real causes of allergies? And what are the indications of having allergies?
Some scientists are not sure of the real reason behind the question why people are having allergies. They said that allergies originated thousand years ago and until today, they do exist. Scientists also believe that allergies can be inherited from our parents, like for example, if a parent has an allergy on something, maybe his or her children are more likely to develop the same allergies.
But leaving the historical aspect, exposure to allergens is the real reason that triggers allergies, especially when one has a weak immune system. Common allergens are pollens from tress, weeds and grasses, house dust, saliva excreted by our pets, smoke from cigarettes, molds, cockroaches and dust mites. And also having some risk factors can also contribute in having allergies. Viral infection and pregnancy are some of the risk factor but absence of having these does not assured us of that we are safe from having allergies.
Some symptoms of having an allergy are very common to others. These indications are; often sneezing, having clogged nose, coughing, itchy eyes, skin and throat, having a dark circles under your eyes or commonly known as allergic shiners, watery eyes and conjunctivitis. But if symptoms are becoming more perilous, you need to consult your physician to have a medication.
There are a number of ways to prevent them but the best ways is by having a clean and garbage free environment and for your assurance and safety, by having allergy shots, because one should not suffer just because of these irritation that can be prevented.
