If you feel as if every mosquito in a 50-mile radius has you locked in its sights, while your friends are rarely bitten, you could be right. Up to 20 percent of us are highly alluring to mosquitoes—and scientists have discovered some surprising reasons.
“Both your metabolism and your unique body chemistry—which is as distinctive as a fingerprint—play an important role in determining whether or not you’re a mosquito magnet,” says University of Florida entomology professor Dr. Phil Koehler. “Also, there’s evidence that your degree of attractiveness to mosquitoes can change over time.”
Here are some intriguing discoveries about why some of us are particularly tasty targets for the tiny vampires:
Mosquitos prefer blood type O
In their quest for a meal, mosquitoes are nearly twice as likely to land on people with type 0 blood than those with type A, according to a Japanese study. Indeed, the biting pests consider type 0 more delectable than any other blood type, the researchers reported. Most people secrete substances that allow mosquitoes to identify blood type before they bite.
Beer drinkers beware
Swigging just one bottle of beer can significantly boost your risk of being bitten, according to a study published in Journal of the American Mosquito Control Association. The researchers reported that, “Mosquito landing on volunteers significantly increased after beer ingestion compared with before ingestion.”
