Porque é que sou mais picado que os outros?

Se bem que o que é verdade na Irlanda pode não o ser aqui e repetindo a notícia para compilar uma lista completa de motivos conhecidos pelos quais algumas pessoas são mais picadas que outras:

Quoting:
"An estimated 10-20 per cent of people are highly attractive to mosquitoes and consistently get bitten more often than their counterparts.


  • Research suggests that mosquitoes are attracted to exhaled carbon dioxide, as well as chemical compounds secreted in skin and sweat, including lactic acid, uric acid, ammonia, steroids, and cholesterol to name a few. 
  • Certain bacterial species that naturally inhabit human skin, e.g. Staphylococcus epidermidis, make individuals more attractive to mosquitoes whilst others e.g. Pseudomonas aeruginosa, appear to have the opposite effect. 
  • Research also suggests that certain blood types are more attractive to mosquitoes than others. A large number of the population secrete saccharides or sugars through the skin dependant on their blood type that mosquitoes are able to sense. 
  • Studies suggest that mosquitoes seem to prefer those with Type O blood and land on skin with Type O blood nearly twice as often as those with Type A.
  • Mosquitoes are also attracted to dark colours such as black and navy blue, as they use vision along with scent to locate their targets. It is best to dress in light colours such as white or pastels to reduce the risk of this.
  • Pregnant women are more susceptible to bites. This is likely due to the fact that they exhale relatively more carbon dioxide and have a higher resting body temperature."
