summertime ’s virtually here , which means before long many of us will be disenable through sneezes , coughing , and fidgety eyes . While allergies are a pain in the fanny , they may not be the misguided resistant responses many scientists have believe them to be . In fact , a new theory is emerging which suggests thatthey may have evolvedto protect us .
Many immunologist remember that allergic reaction to everything from peanuts to pollen are just misdirected bodily reply , the type that ’s typically directed at parasites . The result is an attack to spew the body of the non - actual invaders — by sneeze , cough , itching , and everything else that happens in good order before you reach for the Benadryl .
But a researcher from Yale University has a different idea . Ruslan Medzhitovpoints outthat parasites and the substances that induction allergies , called allergen , have nothing in coarse — so why on Earth should the organic structure react in the mode most immunologist intimate ?
alternatively , he thinks that allergies are an evolved trait , which help oneself protect humanity from toxic substances in our surroundings . write in an clause published in Nature , he explains :
“ How do you hold against something you inhale that you do n’t want ? You make mucous secretion . You make a fluid nose , you sneeze , you cough . Or if it ’s on your pelt , by hasten itching , you avoid it or you endeavor to remove it by scratching it . ”
And he ’s got the evidence to back that up . Some allergic response , for instance , seem to degrade and detoxify Snake River and bee venom , while others seem to prevent pests from burn or stinging again . It makes sense that such a response should be preferential evolutionarily .
His argument does n’t needs belie the hygienics hypothesis , which suggests that kids grow up on farms are less likely to develop allergic reaction . That theory rests on a underlying and direct modification in resistant reaction , which trumps the family of supersensitive reactions — so the two ideas can jubilantly coexist .
Whether the hypothesis turns out to be adopted by the total scientific residential area remain to be seen . But in the meantime , take consolation in the fact that your allergy might actually put you at an evolutionary advantage over your non - suffering friends . [ NatureviaScientific American ]
