Why do mosquitoes bite some people more than others?

If when you are with a group of people, mosquitoes only bite you and not others, surely you have wondered what you have done to have such bad luck.Science explains it to you!

Popular legend says that mosquitoes bite people with the sweetest blood , but this has nothing to do with reality.Mosquitoes bite some people more than others by different causes.

Carbon dioxide

According to a study published by Nature, mosquitoes have olfactory cells called CPA neurons , which are capable of detecting the amount of carbon dioxide we emit, one of the main factors that they take into account when selecting their victims.

A human being generates every day around of a kilogram of CO2 , and every time you exhale, about 13 times per minute, it produces more than one hundred milligrams, although the exact amount depends on the metabolism, diet and physical exercise performed by the person in question.

For mosquitoes, a greater amount of carbon dioxide means that there is a lot of fresh blood to that attack, therefore, select the people who emit more CO2.

Why do mosquitoes bite some people more than others?

With age, these amounts increase, being smaller in children, although the queens in CO2 emission are the pregnant , especially in their last stage where they can produce up to 21% more carbon dioxide .

Sweat and smell at feet

The same CPA neurons can also detect the odors of human skin, to choose the people who give off the ones that attract them most.

Among them lactic acid, which we emit when breathing and sweating, and which is It is more present in the taller people and in pregnant women.

Therefore, sweat is another element that attracts the most mosquitoes.If we have just exercised or it is very hot and we are sweating, we will multiply our chances of receiving bites.

In fact, sweat on summer nights is the main reason why we get ached while we sleep.Experts advise taking a shower before bedtime to avoid bites.

Why do mosquitoes bite some people more than others?

Another of the scents of mosquito favorites, scientists at Wageningen University in the Netherlands have shown , is the smell of feet , which, in addition, is the favorite of the 'Anopheles gambiae', the transmitter of malaria, so we must monitor our hygiene.

Genet ica

A study by James Logan and the London School of Hygiene and Tropical Medicine, highlighted that the fact that we attract more mosquitoes is conditioned to the molecules that form our own body odor.

While there are some people who produce natural repellents, others have an odor that inevitably attracts mosquitoes to them.

Blood group

The 'Journal of Medical Entomology' published an investigation in which it was found that mosquitoes bite people twice with blood type O that those who have blood from group A.

Why do mosquitoes bite some people more than others?

On the other hand, the people of the blood group B are located in the intermediate zone between both in terms of number of bites.

Cer veza

Although it seems incredible, a study that was released in the 'Journal of the American Mosquito Control Association', proved that if you drink beer is more likely Let the mosquitoes go to you if you don't.

How to avoid mosquitoes?

To avoid mosquitoes, we can buy some antimicrobial plants , such as sage, which acts as a repellent, or rub our skin with eucalyptus, cumin, thyme or cinnamon that usually deter them.

It is also convenient not to use perfume or colognes, especially with sweet and floral smells, or use creams or lotions containing lactic acid.

So you know, try to maintain your body hygiene without perfumes or lotions and control yourself when it comes to beer to manage to keep as far away Possible to mosquitoes.

Will there be a Mega Tsunami in Hawaii?

The possibility of a mega tsunami in Hawaii does not seem to be pulled by the hair, if we consider that most of these catastrophes occur precisely in the Pacific Ocean, and that in the last 12 years we have had at least 3 big tsunamis : the one from Malaysia in 2004, the one from Chile in 2010 and the one from Japan in 2011. Will there be a Mega Tsunami in Hawaii? If you are a reader from Science Daily Online and you live in Hawaii do not panic, apparently the possibility that a mega tsunami hits the Hawaiian archipelago in the next 50 years is only 3%, and this information is derived from a study of 5 years by researchers at the University of Hawaii at Manoa (UHM), which began just shortly after the 9.0 earthquake that shook Japan in 2011, and was followed by an even more devastating tsunami. The Investi gators evaluated the behavior of the different plates and tectonic faults that cause earthquakes and tsunamis in the Pacific, as well as the behavior of some large tsunami...

The incredible Feynman technique. Understand anything in 4 steps

Richard Feynman, Nobel Prize in Physics, author of valuable scientific works, including the theory of quantum electrodynamics, was also recognized for his magnificent ability to explain from the most complex to the simplest , in such a simple way that any individual would understand. Behind that there is a methodology that guarantees learning on any subject, in only 4 steps.It is the Feynman technique, a mental model created by the “ great explainer ”, with whom he was able to succeed during his years of academic training at Princeton University.In later years, this same tool made him a great scientific disseminator by getting audiences unfamiliar to his branch to attend the message with absolute clarity. Understand anything in 4 steps with the Feynman technique What are you interested in learning? Is there any matter that arouses curiosity in you and about which you think you have a certain domain?

Here we go! 6 facts about Einstein that you surely do not know 1.Its authorship on the theory of relativity was debated The theory of relativity was full of accusations of plagiarism by German scientist David Hilbert and his supporters, because Hilbert claimed that it was he who had first discovered the theory and that Einstein had taken all the credit .In his defense, Einstein I affirm that it was Hilbert who had copied some of his documents. At the beginning it was thought that every scientist had discovered the theory by his side, but that was until it was discovered that, in fact, Hilbert had stolen some documents of Einstein without giving him any credit.

Scientists say that this woman has the perfect body and her secret is in a part that nobody expected

Although what is attractive to each person is completely subjective, scientists have determined the measurements and proportions of the perfect female body and if that were not enough, they have found a perfect example of this standard in Kelly Brook, a British model, actress and TV presenter, whose curves have won him the admiration of many. Science supports him: this woman has the perfect body.Find out where the secret is. Although they say that beauty is in the eye of the observer, science believes that the model, actress and TV presenter Kelly Brook is still the possessor the most perfect figure of the world. The researchers at the University of Texas have again checked their data several years ago and decided that the Kent girl is perfect in almost every way.They conducted another study and found that the model born in Rochester, now 32, has the "perfect figure". Specifically it has a height of 1.68 and measures 99-63-91 in bust, weight and hips. The s...
