Mosquito season is in full swing. A lucky few people seem immune to the bites of the pesky insects. Others cant seem to avoid them.
New research explains mosquitoes apparent selectivity. According to an article in Smithsonian magazine, an estimated 20 percent of people are especially delicious to mosquitoes.
Why? A number of factors are at play. Chief among them is blood type. Type O is at the top of the list. Also, about 85 percent of people secrete a chemical signal that indicates their blood type; these secretors are more prone to bites regardless of their blood type.
Another factor is the amount of carbon dioxide people emit when they breathe. Larger people exhale more of the gas, which may explain why adults tend to get bitten more than children. Pregnancy, which increases body temperature and carbon dioxide emission, may also increase the likelihood of bites.
And if youre enjoying a beer at a barbecue, you may have made yourself a mosquito target. No one has been able to pinpoint why.
