Allergies, one of the few things that makes life really suck at times, it stops you from enjoying the simple things. Living with the fear of a certain flower, animal or fruit isn’t just right, always watching what you touch, eat or smell can be a of a bother, not to mention the life-threatening episodes.
Despite being deathly allergic to simple things in the environment, some people don’t have that problem, they can frolic in the sun and sniff all the flowers they want without being concerned. So how is it that some people have allergies and others don’t?
The Immune System
It’s a pretty good question there are several theories on the matter but it all boils down to the immune system. The immune system is very much like other vital systems in the body, it receives input from the environment, what makes the immune system so special is that it produces an adaptive response from information supplied by the environment.
The immune system is essentially the security system of the body, it scans the body for foreign entities like bacteria, parasites and microorganism and launch attacks to prevent them from causing an infection, it also discards damaged or defective cells. The immune system deals with a foreign entity by creating antibodies that are to be activated when they come in contact with the foreign entity, long story short when an attack is dealt with the immune system remembers, that’s how vaccination works.
How Allergies Work?
Allergies occur when the immune system confuse harmless substances in the environment like pollen or protein found in certain fruits and foods for harmful substances like bacteria. The body attacks the substance and causes a reaction, that’s basically how allergies work.
It’s just the immune system conditioned to attack certain bacteria or pollen. Allergies tend to run in the family so there might be certain genetic factors. Early exposure to bacteria, microbes and other substances that might cause allergic reactions come a long way in developing the immune system. The immune system is exposed to an innumerable number of bacteria, accurate responses are developed and recorded, so exposure in the future can be properly acted upon.
Developed Vs Developing Countries
In developing countries there are lesser recorded cases of allergies. With the lack of advanced sanitation found in developed countries, citizens of those countries are exposed to more bacteria allowing their immune system to evolve and accurately respond to bacteria, pollen, etc.
So basically, in developing countries people there rarely suffer from allergic reactions isn’t that weird, at this point rolling in the mud won’t change much, so don’t do it.
It is irrefutable that exposure to bacteria while in infancy can prevent allergies reactions in the future, but what about the family factor. In several developing countries despite the exposure to bacteria some people still find themselves allergic to certain substances. The family factor is completely unpredictable. So, people have allergies due to either genetic factors or exposure.
