Every time I step outside, mosquitoes attack me immediately. So, why is it some of us always gets bitten while others get away? Well, now it seems scientists have found the answer.
Previous observations seemed to show that larger persons, who tend to produce more CO2, beer drinkers, and pregnant women, were particularly exposed for those flying little devils. Diets have also been suspected as a factor for a long time. However, none of these factors seems to be the reason.
Instead, scientists claim to have found the explanation in a brand new study, writes IFL Science. By using volunteers from a group of female identical and non-identical twins, they could separate the effects from nature and the effects from genes.
The brave volunteers put their hands into a cloud of 20 mosquitos, only separated by a specially designed Plexiglas. The reason was to see if their smell either attracted or repealed the mosquitos.
And the result was stunning: 67% of the differences between humans depend entirely on genes.
So, what’s the explanation?
Some years ago, a similar twin study showed that the smell from our forearm is genetic. And this works both ways; in the way we perceive the scent from other peoples forearms, and the way we produce our own smell. And the mosquitoes work the same way. There’s a big difference between the scents that attracts them and the smells that repels them.
So, the next time you get a mosquito bite that is itching like crazy: don’t blame bad luck or bad insect repellent.
Instead, try to appreciate the fact your genetic composition creates an amazing smell, irresistible for mosquitos.
