[FACT OR FAKE #27] Mosquitoes Prefer Some People's Blood Over Others
Do Mosquitoes Really Prefer Some People More Than Others?
The short answer is yes. Mosquitoes do exhibit blood-sucking preferences, say the experts.yahoo.net
New research explains mosquitoes’ apparent selectivity. An estimated 20 percent of people are “especially delicious” to mosquitoes. They are bitten more often than others.washingtonpost.com
But it's not dinner they're sucking out of you. Female mosquitoes -- males do not bite people -- need human blood to develop fertile eggs. And apparently, not just anyone's will do.universityherald.com
Why Is It So?
One Of The Main Factor Is Blood Type
Carbon Dioxide Too Happens To Be One Of The Reasons Involved
One of the key ways mosquitoes locate their targets is by smelling the carbon dioxide emitted in their breath—they use an organ called a maxillary palp to do this, and can detect carbon dioxide from as far as 164 feet away.smithsonianmag.com
As a result, people who simply exhale more of the gas over time—generally, larger people—have been shown to attract more mosquitoes than others.huffingtonpost.com
This is one of the reasons why children get bit less often than adults, on the whole.yahoo.net
Exercise and Metabolism Plays Another Factor. In Other Words, If You Love Working Out, Mosquitoes Will Love Sucking Your Blood Out.
In addition to carbon dioxide, mosquitoes find victims at closer range by smelling the lactic acid, uric acid, ammonia and other substances expelled via their sweat, and are also attracted to people with higher body temperatures.universityherald.com
Because strenuous exercise increases the buildup of lactic acid and heat in your body, it likely makes you stand out to the insects. Meanwhile, genetic factors influence the amount of uric acid and other substances naturally emitted by each person, making some people more easily found by mosquitos than others.smithsonianmag.com
And If You Are Expecting, Beware. Because Mosquitoes Are More Attracted Towards Pregnant Women.
Moms-to-be get bitten about twice as often as women who aren’t pregnant, increasing their risk for bug-borne diseases, according to a study conducted in Gambia.yahoo.net
This is likely a result of the fact the unfortunate confluence of two factors: They exhale about 21 percent more carbon dioxide and are on average about 1.26 degrees Fahrenheit warmer than others.smithsonianmag.com
Mosquitoes, Like Vampires, Prefer Dark Clothes
This one might seem absurd, but mosquitoes use vision (along with scent) to locate humans, so wearing colors that stand out may make you easier to find.smithsonianmag.com
In one study comparing the appeal of various hues to mosquitoes, the researchers reported the following results: black (most attractive); red (very attractive); grey and blue (neutral); khaki, green, light khaki, and yellow (less attractive).yahoo.net
Also, If You Like To Drink Beer, Be Careful There
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.webmd.com
No one has been able to pinpoint why drinking beer makes people more attractive to mosquitoes.washingtonpost.com
Some have theorized that the elevation in body temperature and the amount of ethanol in sweat may play a role, but neither theory has panned out. Still, it appears that even a 12-ounce bottle is enough to do the trick.wsj.com
How Can You Avoid Getting Bitten?
Female mosquitoes are driven to bite you as they need a blood meal to complete their reproductive cycle and produce fertile eggs, which takes a huge boost of protein. To reduce the chances of being bitten, wash with an antibacterial soap to reduce the volume of mosquito-attracting bacteria on your skin.thedailybeast.com
Avoid the outdoors at dawn and dusk, when mosquitoes are most active. Set up an outdoor fan to shoo bugs away. And wear long trousers and shirts if it's not too hot.wsj.com
Experts also suggests spraying your clothing with repellent that contains DEET, a chemical that acts to confuse the mosquito's olfactory receptors.yahoo.net
