What kind of people are mosquitoes willing to bite?

When mosquitoes bite humans, they like people who are rich in cholesterol or vitamin B. This is because only female mosquitoes bite people when they are pregnant. They sting people not only to get protein, but also to get proper cholesterol and vitamin B, so their chemoreceptors are very sensitive to these two objects.

People with high cholesterol are generally obese, so mosquitoes prefer to bite obese people.

Moreover, mosquitoes are more interested in people with obvious body odor, such as people who drink alcohol. After drinking alcohol, alcohol will be decomposed by the kidneys to produce volatile acetaldehyde. Acetaldehyde molecules are very small and will enter the blood through osmosis and circulate to the capillaries of the body. Then it volatilizes through the gap between blood vessels and skin, forming a "wine smell". Because of the strong smell of wine, it will be easier to attract mosquitoes.

Sweating person

If people in the same room sweat a lot and have a strong metabolism, they will also attract mosquitoes. This is because human skin is divided into dermis, epidermis and stratum corneum.

Sweat is excreted to the skin surface through sweat glands in dermis, and the sweat in sweat glands contains some lipid molecules and moisture. After these lipid molecules are excreted by sweat glands, they will be decomposed by microorganisms on the skin surface, and they will produce fragrance in the process of decomposition.

Mosquitoes also prefer people with high blood sugar levels. In ancient Egypt, when people didn't have a good method to repel mosquitoes, Pharaoh would pour honey on the slaves around him and let mosquitoes bite the slaves, thus achieving the effect of repelling mosquitoes for Pharaoh.
