Mosquitoes seem to bite some people more than others, even when everyone is in the same place at the same time, with the same amount of exposed skin.
Mosquitoes can spread diseases like malaria, Zika, and dengue fever and scientists have been investigating the various factors that may make some people more attractive to mosquitoes.
According to the scientists, these are the seven reasons mosquitoes will bite some people than the others
1. Blood type
Mosquitos find some blood types more desirable than others; research indicates that mosquitoes may prefer individuals with blood type O than other blood types. People with different blood types have different sets of specific proteins (antigens) on the surface of their red blood cells and blood type is inherited from the parents.
There are four different blood types.Since blood type antigens can be found in the saliva and tears of secretors, it may be possible that mosquitoes can sense these antigens as they approach a person. Adult mosquitoes survive on nectar for nourishment, but females rely on the protein in human blood for egg production.
Research has found that different species have preferences for different blood types. For instance, the Aedes albopictus mosquito favors type O blood, while the Anopheles gambiae favors type AB.
2. Colour
Mosquitoes use their eyes to target victims. Research shows wearing dark colors (green, black, and red) makes it easier to spot.it is better to opt for softer colors like pastels, beige, or even white instead.
3. Carbon dioxide
Human being release carbon dioxide when we exhale, leaving a trail of carbon dioxide that a mosquito can follow. An increase in carbon dioxide in the air can alert a mosquito that a possible host is close by. Larger people exhale more, so they’re more likely to attract mosquitoes.
Mosquitoes can sense carbon dioxide from a significant distance. In addition, they can see humans from a distance of 5 to 15 meters (about 16 to 49 feet). These two cues help them track humans down and because we exhale carbon dioxide through the nose and mouth, mosquitoes are especially attracted to the head.
4. Heat and Sweat
Mosquitoes have a nose for other scents as well. It can sniff out lactic acid, ammonia, and other compounds emitted in sweat. Strenuous exercise increases the buildup of lactic acid and heat in the body. In addition, genetic factors affect the “odour profile,” which can affect how attractive humans are to mosquitoes. These things make it easier for mosquitoes to find some people than others.
5. Skin
Bacteria on the skin can also affect body odour. The skin is naturally teeming with microscopic life. Bacteria mixed with sweat create a distinct fragrance.
Research has shown that the types and number of bacteria on a person’s skin can play a role in attracting mosquitoes. The bacteria factor could also explain why some mosquitoes are drawn to ankles and feet, an especially ripe spot for bacteri
6. Pregnancy
It turns out that pregnancy attracts some mosquito species. A study in Africa found that twice as many mosquitoes gravitated towards pregnant people compared to non-pregnant people. This is because pregnant women release more carbon dioxide and have a higher body temperature.
7. Alcohol
Research found out that mosquitoes may be more attracted to people who have been drinking and researchers found that significantly more mosquitoes flew toward participants who had drunk one liter of beer than participants who had drunk a liter of water.
