Why Do Some People Get Bitten by Mosquitoes More?

Why Do Some People Get Bitten by Mosquitoes More Often? The Scientific Reasons You Didn’t Know

In summer, many of us notice something strange: while some people remain almost unaffected by mosquito bites, others are constantly targeted by these insects. What is the secret behind this mosquito “preference”? The answer lies in many combined factors.

The role of blood type

Mosquitoes need our blood to reproduce, and it seems they prefer certain blood types. Studies have shown that type O attracts mosquitoes more than types A or B, which explains why some people get bitten more often. Additionally, the skin releases chemical signals that “announce” the blood type, increasing or decreasing attraction.

The invisible trail of carbon dioxide

As we breathe, we release carbon dioxide, which mosquitoes can detect from up to 30 meters away. The more we exhale, the more attractive we become to the insects. That’s why people with higher metabolism or those who exercise become more “tempting” targets.

The smell of sweat and body temperature

Sweat contains substances like lactic acid and ammonia that attract mosquitoes. Also, increased body temperature after intense activity makes the skin more noticeable. This is why exercise or heat raises the chances of getting bitten.

Bacteria living on our skin

Our skin hosts a variety of bacteria, and their type and quantity affect how much mosquitoes are attracted to us. Some bacteria produce odors that insects love, while others may repel them. That’s why some parts of our body are more prone to bites.

Other factors at play

• Flavors and compounds in sweat: New research shows that certain chemicals in sweat can encourage or discourage mosquitoes from biting.

• Beer consumption: One glass of beer seems to increase mosquito attraction, although the reason remains a mystery.

• Pregnancy: Pregnant women exhale more carbon dioxide and have higher body temperature, making them more attractive to mosquitoes.

• The colors we wear: Mosquitoes prefer bright colors like red and black, while they avoid lighter colors like white and blue.

• Genetic factors: Heredity plays a big role in how our body smells to mosquitoes and how attractive we are.

The future of insect repellents

Scientists are working hard to develop new mosquito repellents based on natural mechanisms and modifying skin bacteria. Soon, we might drastically reduce bites, even in mosquito-infested areas.
