Why don t mosquito bites hurt in winter?

Mosquitoes secrete saliva when sucking human blood, saliva contains vasodilating and anticoagulant substances, and the blood circulation of human beings is not smooth in the cold conditions of winter, and mosquito sucking should be said to make people in a more "comfortable" state to a certain extent.

In autumn, when the climate gets cold and the temperature drops below 10, mosquitoes will stop breeding and die in large numbers, and very few mosquitoes will survive, and they will hide in a place where they can shelter from the wind and cold, such as in a warmer and more hidden place indoors, such as behind a wardrobe. However, they will avoid hotter places, such as heating, etc. This can not only avoid the harsh winter, but also reduce the rate of metabolism and avoid starvation.

It's kind of like hibernation. How can a half-dead mosquito have the strength to bite someone?

When the mosquito's mouth pierces **, it seems to secrete a small amount of a substance similar to anesthetic.

When mosquitoes reach the winter, their saliva secretion decreases to keep their stamina alive in the winter, so this is the case when the secretion is very small.

Hungry, there seem to be few mosquitoes in winter.

Big brother, it's because you haven't taken a bath for a long time in winter, and it's thicker! == Jokes...

Probably all male mosquitoes, female mosquitoes are breeding.

The mosquitoes are almost dead.

Winters are cold, and sensitivity decreases.

Because you're wearing thick clothes, or it's too cold and painful.

Are there mosquitoes in winter? Even if we're all dressed!

Yes.

In warmer places indoors, mosquitoes will still come out to move. If the temperature is suitable, some adult mosquitoes actually have good "teeth", that is, they can bite. Whether a mosquito bites a person or not is usually closely related to the ambient temperature, and in a warm room, there is a high chance of being bitten by mosquitoes.

In addition, the winter in northern China is relatively cold, which is a veritable winter. And South China is nominally "winter". For them, all year round is no less. As a result, in the winter in the north, as long as the temperature is suitable, it is not without mosquitoes, and they will bite people.

Mosquito habits. Mosquitoes are insects and are ectotherms, and their survival and reproduction are highly dependent on ambient temperature conditions. The suitable temperature for mosquitoes to survive is around 24-35. When the temperature is below 10, mosquitoes are less and less active, or even inactive and enter a state of overwintering.

Although the number of mosquitoes in winter is significantly lower than in other seasons, it does not mean that they are all frozen to death, and most of them are "lurking" for the winter. They produce physiological adaptations that match the seasonal changes in the climate. The weather is warm, and it comes out to reproduce wildly; When it gets cold, find a place to hide and start the "wintering program".

They generally find a suitable place to enter a dormant or diapause state, stop development, reduce energy expenditure, and slow down the metabolism in the body. If you don't eat or move, you will "recuperate" for the warmer weather the following year.

Reasons why some people don't bite mosquitoes include:

1. There are some special smells on the body, which can effectively avoid mosquito bites, and these smells mainly include bay leaves.

Smell, lemongrass oil smell, garlic flavor, lemongrass.

smell, smell of geraniol, etc.

Second, for the elderly who have a relatively slow breathing speed and slow metabolism, it is not easy to cause mosquito bites.

3. Patients with underdeveloped sweat secretion and relatively low body temperature can reduce mosquito bites.

Fourth, people wearing dark clothes can effectively avoid mosquito bites, and patients need to avoid mosquito bites as much as possible in their daily life, which can reduce the damage caused by mosquito bites to the human body.

Mosquitoes aim at their target prey, mainly through several dimensions:

1. Metabolic speed.

Your metabolism is definitely faster than you are now.

2. Body odor. You're milky, I'm a female mosquito, and I'll bite you after hours.

3. Exhale carbon dioxide.

Look at the carbon dioxide you exhale, and I will know if you are a good prey.

4. The smell of stinky feet.

Mosquitoes have a soft spot for smelly socks.

5. Your own immune rejection sensitivity.

You grow up, your skin is thicker, your sensitivity to mosquitoes is greatly reduced, and many times, you get bitten, but you are not as sensitive as you were when you were a child.

6. Prey environment.

If the clothes are all light-colored, mosquitoes will not be very close. Because there is a sense of insecurity about it.

7. You keep turning on mosquito coils.

Or some external factors.

There are several reasons why mosquitoes don't bite

1.Personal odors: Everyone's scent is different, and some people's scents may be less attractive to mosquitoes. This may be related to factors such as your diet, medication use, the composition of your sweat, etc.

3.Blood type: Certain studies have shown that mosquitoes prefer people with a specific blood type. For example, some studies have shown that mosquitoes prefer people with blood type O.

4.Temperature: Mosquitoes prefer warm ones because warm ones are easier to find blood vessels. If your temperature is low, mosquitoes may not bite you easily.

5.Keeping clean: Keeping your body clean and your clothes clean to reduce body odor and odor may reduce the chance of mosquito bites.

In conclusion, being bitten by a mosquito is related to a variety of factors such as an individual's physique, clothing, and surroundings.

There could be many reasons why mosquitoes don't bite you, and here are some possible explanations:

1.Physiological factors: Mosquito bites are a way for them to get nutrients, and they are more inclined to bite certain types of people.

For example, people with higher cholesterol or blood sugar levels tend to be more susceptible to mosquito bites. Therefore, if you have low cholesterol or blood sugar levels, you may be less likely to be bitten by mosquitoes.

2.Temperature factor: Mosquito activity is also lower in areas with cooler temperatures, so if you're in a cooler area, you're likely to be less likely to be bitten by mosquitoes.

3.Avoid bites: If you take some bite-avoiding behaviors, such as using insect repellent, wearing long-sleeved clothing, or choosing early morning or evening when you are outdoors, you may reduce your chances of being bitten by Nakon mosquitoes.

4.Mosquito species: Different species of mosquitoes have different biting preferences, some may prefer to bite people, while others prefer to bite other animals. So, if there are different mosquito species in the area you live in, there may be some species that bite humans less.

5.Personal odor: Mosquitoes are sensitive to certain odors vary, so if you don't have an attractive scent to mosquitoes, you may be less likely to be bitten by mosquitoes.

6.Genetic factors: Studies have shown that some people's genes may make them less susceptible to mosquito bites and therefore less likely to be bitten by mosquitoes.

In conclusion, there could be a variety of reasons why mosquitoes don't bite you, but it can also be temporary. When we are outdoors, there are still some things we need to do to protect ourselves from mosquito bites.

It is very likely that because of the low cholesterol infiltration content and vitamin B levels in the body, mosquitoes will look for the target through the smell and exhaled carbon dioxide, and the lack of mosquito bites may be due to the need to pay attention to personal hygiene in daily life, ** There is no abnormal smell of cherry blossoms, in addition, if you wear light white clothes when you are in the cold, you can effectively reduce the situation of mosquito bites. Medical analysis can be seen, in fact, the probability of being bitten by mosquitoes and the content of cholesterol in the human blood has a certain relationship, through the analysis, you can understand that the blood cholesterol content is relatively high and people with low cholesterol content in the blood compared with the probability of being bitten by mosquitoes, in addition, the probability of being bitten by mosquitoes is also related to the sweat secreted by the human body. Then it is rare to be bitten by mosquitoes.

Because the room is warm enough and there are eggs left in the room. Mosquitoes lay eggs before the weather gets cold, and only some of these eggs will freeze to death, and the rest will only need to be hatched at the right temperature, and generally develop from larvae to adults in 10 days. So, as long as the temperature in the room is right in winter, there will also be mosquitoes.

In winter, if the local symptoms are not serious, only redness and swelling, accompanied by itching, there is no need to deal with it; If the local symptoms are more severe, such as itching and erythema, blisters often appear, or erosions, it is recommended to seek medical attention in time for further **.

Precautions for eliminating mosquitoes in winter.

Many residents still retain the old idea of choosing canned insecticidal aerosols to kill mosquitoes, as soon as they are sprayed, the smell is very strong, and mosquitoes will die immediately if they come into contact with it. But aerosol insecticides are a symptom but not a cure, kill a batch will come again, never kill, if only rely on aerosol insecticides to open the way, not only can not kill mosquitoes, long-term use, their own body will also be harmed. In particular, it is more harmful to children, and long-term use will increase the chance of leukemia in children.

The general treatment method is to drain the water in the gutter so that the mosquitoes no longer have a breeding ground and the mosquito larvae will not be present. Adult mosquitoes, directly use insecticides to kill and eliminate adult mosquitoes; Taking such measures can greatly reduce the mosquito base to prevent mosquito infestation in the coming year.

The reason why mosquitoes do not bite is that the sweat secreted by the human body in summer contains "trimethylamine", which is easy to attract mosquito bites.

If you wear dark blue or brown clothing, you are more likely to be bitten by mosquitoes. So in the summer you should wear light-colored clothes.

Indoor flower arrangement can also repel mosquitoes. Before dusk, put one or two pots of mosquito repellent grass or blooming jasmine, Milan, cordyceps, seven-mile, fly plum or rose, evening primrose indoors, and plant one or two tomatoes in indoor pots. Run away because mosquitoes can't tolerate the smell of these flowers.

Ignite a few pieces of dried orange or orange peel indoors and mosquitoes will flee in a hurry.

Mosquitoes belong to the family of insects of the order Diptera, and there are about 3,000 species in the world. It is a small flying insect with stinging and sucking mouthparts. Usually females feed on blood, while males suck the sap of plants.

Blood-sucking female mosquitoes are intermediate hosts for other pathogens such as dengue, malaria, yellow fever, filariasis, Japanese encephalitis, etc. Mosquitoes are found on all continents except Antarctica. Among them, the genera Anopheles, Aedes and Culex are the most famous.
