There is always one . That person who , no matter what , always come back from spending a affectionate summer even sitting outside covered in mosquito bites . Whilethere is some grounds to suggestthat people are really bad at knowing whether or not they are the unlucky ones , there are thing that can increase your likeliness of getting bitten . Although there is wad of anecdotic evidence from multitude about what influences the small critters to bite , from feed garlic to having “ sweet ” stemma , there are some expression that have been proven by science to truly increase your chances .
Blood Type
Unfortunately , not all of the causes are something you could actually do something about . Take blood type , for model . One study has foundthat while those who have blood case group O coursing through their vein are more probable to get a less than friendly sojourn from a mosquito than other rakehell types , they ’re only more attractive to the insects when compare with those with blood character A. They found that a particular kale see in blood type O was attractive to the mosquitoes , though once a mosquito has pick its fair game , it ’s unlikely profligate type will make much difference .
Carbon Dioxide
Another thing that we all have to do is breathe , and this is n’t great if you ’re trying to avoid the vexing little biters . When homing in on their target area , all mosquito species will use something called a maxillary palp to smell out the carbon paper dioxide you ’re exhaling . Mixed with the host ’s consistence odor and both moleculeshave been observe toinduce a take - off and sustained flight of the insects . It is for this rationality that people who take a breath out more , including big people and grownup , tend to get bitten more than those who exhale less .
Lactic acid
The pesky piddling insects are not only searching for atomic number 6 dioxide , they are also on the lookout for other marker too . One of these , it seems , is lactic acid . Research has shownthat icteric fever mosquitoes are significantly more attracted to those who have more lactic acid on their hide , even making those who were less “ attractive ” to the insects more attractive . This , in addition to an step-up in body temperature , could go some way to help explain why those who have just exercised seem more potential to get bite .
maternity
The previous movement could also be related to why it seems that significant women are more likely to receive itchy ruddy bites . One studyfound that women in the late stage of pregnancy give forth 21 pct more breather – admit that crucial carbon dioxide – when compared to non - pregnant charwoman . Another reason could be link to the fact that gestation increases blood catamenia to the skin , which means that on ordinary they run at around 0.7 ° speed of light warmer than normal , making them easier for heating plant - seeking insect to find .
Beer
This one is a little litigious . Whilea study has antecedently foundthat by drinking as trivial as 350ml of 5.5 pct beer the act of mosquitos on the volunteer ’s skin importantly increased , it was only a very limited report of 13 people . Not only that , but it does n’t inevitably mean that the insects then move on to fertilize on them , and the researchers even go on to say that they found no correlation between the amount on ethanol detect in the sweat and the amount of beer really consumed . So while it could be a factor , it is a far from ensconce topic .
