Does drinking alcohol attract mosquitoes to bite?

Drinking alcohol may attract mosquitoes to bite. This is primarily because, after alcohol is metabolized into acetaldehyde in the body, acetaldehyde has the effect of dilating capillaries, leading to increased sweat gland secretion through the skin, which may alter body odor or exhalation, making an individual more attractive to mosquitoes. Additionally, increased blood alcohol concentration and elevated body temperature after alcohol consumption may also contribute to attracting mosquito bites. Although the exact mechanism is not yet fully understood, multiple studies and observations indicate that people who consume alcohol may indeed be more susceptible to mosquito bites. Therefore, during summer months or in environments with many mosquitoes, it is recommended to pay attention to personal protection after drinking alcohol to reduce the risk of mosquito bites.
