Many people complain that mosquitoes bite them more than others. The problem worsens in summer with rising temperatures, especially since during this time of year, everyone tends to spend most of their time outdoors, according to a report published in HuffPost. It may seem strange, but mosquitoes do indeed choose some individuals over others, and this feeling is not just an illusion.
Why do mosquitoes bite some people more than others? A range of factors contributes to this. A new study has shown that mosquitoes bite individuals with blood type O+ at twice the rate compared to those with blood type A. According to researchers, this is related to the secretions produced by some people, which particularly attract mosquitoes. Therefore, blood type plays a role in attracting mosquitoes to certain individuals.
There may also be a relationship between the amount of carbon dioxide produced. As carbon dioxide production increases, so does metabolic activity. Genetic factors and other elements that also increase carbon dioxide levels can contribute to attracting mosquitoes. However, what distinguishes humans from things that produce carbon dioxide, such as cars, are secondary indicators like lactic acid produced by the body, which causes muscle contractions during exercise and is secreted through the skin, signaling mosquitoes and guiding them to humans as targets for biting.
Mosquitoes possess other characteristics and features that help them distinguish humans and select them as targets for biting, such as their excellent vision. They can recognize humans by their clothing. Thus, what we wear is crucial in avoiding or attracting mosquitoes. Dark clothing can attract mosquitoes at higher rates, while light clothing attracts fewer.
On the other hand, mosquitoes rely on criteria related to touch when landing on human skin. This is connected to genetic and physiological factors. It appears that some people's bodies are warmer, making them more attractive to mosquitoes, as these insects look for areas where the blood is closer to the skin.
Health and lifestyle factors also play a role:
- Engaging in physical exercise
- Elevated body temperature
- Pregnancy
- Overweight
- Alcohol consumption
All these factors increase metabolic activity and thus make an individual more attractive to mosquitoes. One study even showed that consuming a small amount of alcohol could influence and increase the likelihood of attracting mosquitoes.
How can you avoid mosquitoes?
- Avoid going out during peak times, specifically at dusk and dawn
- Cover your skin when outdoors, especially during peak times and in areas where mosquitoes are abundant
- Use sprays or creams that repel mosquitoes.
