According to research from France published in the journal PLoS One, the more you drink beer the body will be more vulnerable to mosquito bites.
Researchers reached that conclusion after testing 43 volunteers aged 20-43 years who were declared hale and hearty.
The volunteer team was then divided into two groups, 25 people were asked to spend 1 liter of beer with 3% alcohol content and the rest were asked to drink plain water in equal portions.
Before drinking anything, they are first asked to remain in a room full of mosquitoes to measure how vulnerable they are usually bitten by mosquitoes.
Afterwards, they were asked to drink (water and beer for each group), and then return to the same room.
The results were found, people who had finished drinking beer were bitten by 47% more mosquitoes than before drinking and than people who only drink water.
About 65% of mosquitoes also react 15 minutes faster to fly toward the body of beer drinkers. Compared to before drinking beer, mosquitoes that fly towards participants are only 35 percent.
Meanwhile, water consumption has no effect on human attractiveness to mosquitoes.
The mosquitoes examined in this study were Anopheles Gambiae mosquitoes that cause malaria in West Africa.
Previously there was one study that examined the effects of being bitten by Aedes mosquitoes after drinking beer.
In addition, there is also a small study from Japan published by the Journal of the American Mosquito Control Association (JAMCA) in 2002.
This study looked at 13 people (men and women) aged 20-58 years to find out how vulnerable they were to be bitten by mosquitoes after drinking beer.
In this case, the researchers tested ethanol levels in sweat, sweat production, and skin temperature before and after drinking 350 ml of beer (with 5.5% alcohol content).
The results are similar. Participants are more easily bitten by more mosquitoes after drinking beer than before.
The team of researchers from France suspected that the breath and body odor typical of beer drinkers invited more mosquitoes to approach.
The smell of breath and the body of beer drinkers also make mosquitoes fly faster to the location of the smell. Researchers from Japan also found the same thing.
In theory, after drinking beer, alcohol is quickly absorbed from the digestive tract and flows into the blood and then metabolized in the liver.
Fifteen minutes is enough time interval for the alcohol content present in the blood, breath, urine, and sweat since the last sip.
However, these two studies found no link between the high ethanol content in sweat, exhaled carbon dioxide levels, and changes in skin temperature after drinking beer with the chance of landing a mosquito on the body.
