If mosquitoes always seem to feast on you while your friend goes untouched, it is not your imagination, and science explains why. The first thing that draws them in is carbon dioxide, the gas you exhale, and people with a higher metabolic rate give off more of it, which is why the pregnant, the physically active, and anyone who has had a beer become mosquito magnets. Next comes your personal scent, since the sweat compounds like lactic acid and the bacteria living on your skin create a body odor that some people simply broadcast more strongly. Genetics play a big role too, as studies of twins show, and blood type may matter a little, with some research finding mosquitoes prefer Type O. Body heat and even dark-colored clothing help them zero in for the final landing. The frustrating truth is you cannot change much of your natural chemistry, but you can fight back by using an EPA-approved repellent like DEET, wearing lighter colors, and clearing standing water where they breed. So if you are the family's designated mosquito magnet, blame your biology. Follow for more science that explains everyday mysteries, and share this with your itchiest friend. #Mosquitoes #SummerSafety #ScienceExplained
