Being bitten by a mosquito when you are just relaxing outside the house or walking around is certainly a little annoying. But when looking around, it turns out that only you are busy scratching bumps while others are calm. Have you ever wondered why mosquitoes sometimes target only certain people?
What causes a person to be bitten more easily by a mosquito?
In fact, there are people who are more attractive to be used as food for mosquitoes. This is mainly related to the component of blood and aroma that is released by one's body.
Even so, one of the main reasons why someone is more susceptible to being bitten by a mosquito is 85% due to genetic factors. Other factors include physical activity, sweat, personal hygiene, even pregnancy, all of which can affect how vulnerable you are to being bitten by a mosquito.
1. Larger body size
One of the things that makes you vulnerable to being bitten by a mosquito is how much carbon dioxide you produce from the breathing process. Carbon dioxide is one component that attracts mosquitoes to come.
This also explains why mosquitoes prefer to bite adults or larger people (both their weight and height) because automatically, larger people will produce more carbon dioxide.
Mosquitoes can smell the carbon dioxide we produce from 50 meters away through a special organ called the maxillary palp.
One reason is still related to the levels of carbon dioxide produced. Pregnant women emit more carbon dioxide than normal people in general.
In addition, the body temperature of pregnant women is usually slightly higher when compared to ordinary people. This invites mosquitoes to approach pregnant women.
3. High cholesterol
Not that mosquitoes will only bite those who have high cholesterol levels in the blood. You might be the type of person who is more efficient in processing cholesterol, so the by-product of cholesterol metabolism is left on the surface of your skin.
This is what invites mosquitoes to land. Not only cholesterol, those who have high steroid levels on the surface of the skin are also more attractive to mosquitoes.
As quoted by WebMD, John Edman, PhD, an entomologist or insect expert from the Entomological Society of America, states that those who produce certain acid components such as uric acid are excessively susceptible to mosquito bites. This is because these substances can trigger the sense of smell of mosquitoes, thus provoking mosquitoes to come.
5. Blood type O
A study published by the Journal of Medical Entomology in 2004 stated that mosquitoes often perch on those who have blood type O. This possibility is two times greater than those with blood type A. While blood type B in the study it's in the middle.
There is no scientific explanation why blood type O is more attractive to mosquitoes. But it turns out that in some people, our blood group can be 'read' by mosquitoes because of the chemical compounds found in our skin.
6. You just exercised
Believe it or not, exercise also makes you very attractive to mosquitoes. This is caused by two things. After exercising, you tend to produce more carbon dioxide because usually someone will breathe more often and faster.
Besides carbon dioxide, another component in your sweat that is produced by sweat glands, lactic acid, also invites mosquitoes to come.
7. You may be more sensitive to mosquito bites
One reason why only you yourself are busy with mosquito bites is because your skin is more sensitive, so maybe other people are also bitten by mosquitoes, but your reaction to mosquito bites is greater than those who do not have sensitive skin.
When someone who has sensitive skin is bitten by a mosquito, the bite can trigger inflammation in the bitten area. The reaction can be more severe, such as bigger bumps or swelling, or unbearable itching.
So even though your friend might also be bitten by a mosquito, but if your skin is sensitive, you will be more quickly aware of mosquito bites, making you conclude that mosquitoes are only after you.
