Lice from nerves myth or reality. Can lice appear from the nerves. Lice from stress: is it lice

This article reveals the essence of such a disease as pediculosis, its causes and methods of treatment. Also here are considered the main types of lice, their life cycle.

1. pubic louse;
2. human louse, the latter of which is divided into head and body louse.

Louse pubis

It has the following properties:

• Gets rid of mosquitoes, cockroaches, rodents, ants, bedbugs
• Safe for children and pets
• Mains powered, no recharging required
• No addictive effect in pests
• Large area of ​​action of the device

Life cycle of head lice

On average, it is believed that the life cycle of head lice is 3-4 weeks (at best - 16 days, at worst - 40 days), during which the louse lays 2-3 hundreds of nits.

At the same time, the life cycle includes several stages of development:

1. Fertilization.
2. laying eggs- nits are attached by the mother to the human hair with a sticky liquid a few centimeters from the scalp, which makes it resistant to shampooing. The duration of this stage is approximately one week.
3. Larva. The nit turns into a larva, which takes from 1 to 10 days, depending on the environmental conditions.
4. Nymph. The larva, having shed its skin, turns into a nymph, which is an insufficiently mature individual. The duration of this stage is a week, during which the nymph sheds two more times and turns into a formed louse.
5. Adult insect - imago has the peculiarity of reproducing and laying eggs two days after its first food sample.

How long does a louse live without a person?

As noted above, the body louse can live without a person for up to 4 days, the head louse - up to 2, and the pubic louse - up to 9 hours. Moreover, their life expectancy is reduced or increased depending on the air temperature.

Stories from our readers!
“We spend the whole summer in the country, there are a lot of mosquitoes, flies and midges. It is impossible for adults or children to be in the house, and even more so on the street. We bought a trap lamp on the advice of neighbors.

We have been using the lamp for over a month. We forgot about flying insects and are often outdoors in the evenings. Very pleased with the result. I recommend to everyone."

Causes of head lice

The main causes of pediculosis infection are:

• Infection from another person
• Non-observance or insufficient observance of the rules of personal hygiene
• Ignorance or neglect of preventive measures
• Frequent change of sexual partners
• The presence of a person in places of high crowding of people during exacerbation of pediculosis (during times of war, hunger strikes, disasters, as well as mass migrations).

Mechanism of head lice infestation

Lice transmission methods

The main method of transmission of lice is contact. This can be contact both directly with the person himself, and with personal items.

For example, infection can occur in the following ways:

• So, head lice crawl from one head to another.
• Pubic lice are transmitted through sexual intercourse.
• Body lice can be contracted through contact with the clothing they live on.
• You can also become infected with head lice through personal hygiene products, such as a comb, hairpin, hat, scarf, and more.

Optimal conditions for the spread of lice

There is an opinion that lice appear only in people living in socially disadvantaged conditions. But this is not so, because most often pediculosis affects well-off children aged 3 to 15 years.

Indeed, for example, in children's institutions, individual lockers are usually not provided, and lice can jump from one clothing to another in a common wardrobe. Moreover, these creatures, despite their small size, are able to overcome distances of up to half a meter.

Lice appears on the head of an adult much less frequently than in children, but when living conditions are the most cramped, which may be in people living in communal apartments, prisons, barracks or barracks, the likelihood of infection with pediculosis increases.

Also among the marginalized society, where there are unsanitary conditions and simply non-compliance with the rules of personal hygiene - an excellent habitat for lice.

Thus, the optimal conditions for the spread of lice for both children and adults are unsanitary conditions, crowding and crowding.

At-risk groups:

1. Children of school and preschool age.
2. Persons who frequently change sexual partners (pediculosis pubis).
3. Persons belonging to disadvantaged strata of society: homeless people, prisoners, drug addicts and alcoholics.
4. Soldiers living in the barracks.
5. Persons living in communal apartments, hotels, marriages.
6. Persons who do not properly follow the rules of personal hygiene.

Treatment

Pediculosis requires urgent treatment, since it does not go away on its own, and it is necessary to prevent the development of complications and the further spread of the disease among the environment of an infected person .

There are two types of treatment:

• Medical.
• Treatment with folk remedies.

Medication treatment

There is a variety of forms of release of medications - ointments, shampoos, creams, lotions, solutions, powders, emulsions, aerosols. All of them are chemical preparations and have an insecticidal, that is, antimicrobial effect.

There are also combined preparations and medicines based on vegetable and synthetic mineral oils.

Folk recipes

with the help of folk recipes:

• Garlic gruel;
• hydrogen peroxide;
• cranberry or pomegranate juice;
• a mixture of kerosene and oil;
• vinegar;
• alcohol;
• salt;
• dichlorvos.

Folk remedies, despite the fact that they destroy lice, are not always safe for humans, especially for children. Therefore, they should be avoided or used with extreme caution.

Conclusion

In our article, we answered the question of why lice appear on the head, and how to get rid of them. It should be remembered that it is necessary to follow preventive measures in order to avoid this unpleasant disease.

Experiences on nervous ground, stress can cause certain diseases, but, fortunately, pediculosis is not one of them. Only from nerves, without really any real reasons, insects in your head are unlikely to appear. You don't have to worry about this. The idea of ​​some people that lice and nits can be in the scalp for years, and manifest themselves completely unexpectedly, under some emergency circumstances that entail stress, is absolutely groundless.

In the same way, there is no basis for the opinion that bloodsuckers start in the hair of a person who is not very neat, and his head can often be dirty, untidy. These judgments of a not very progressive part of the population cannot be called otherwise than a myth or fiction. Remember once and for all: lice are transmitted only from person to person. This means that you can become infected with them through personal contact with someone who already has them. Or if you used his comb, put on his hat, sleep on his pillow.

Can lice appear on nerves in an adult?

The child has

Now let's see if lice can appear in a child on a nervous basis? In principle, age is unlikely to matter here. great importance. If a child, just like an adult, is very worried about something and sweats a lot, he is at risk. Of course, if there is a carrier of lice next to him at this moment. Although it should be noted that children sweat much less often than adults, and the smell of sweat is not so pronounced. However, the fact remains: if there is a carrier of lice next to the child, and for some reason he sweats a lot, bloodsuckers can "go" to the smell.

The long-held opinion that all diseases are caused by stress is ready to attribute the appearance of head lice to the same reason. But to assert it as truly true is possible only as a result of one's own ignorance.

It is enough to rely on laboratory studies, the results of which have long been kept secret by no one, as the incompatibility of the nature of stress and the nature of pediculosis becomes obvious.

The factors provoking the occurrence of stress are psychosomatic in nature, and pediculosis is purely hygienic and social. And, knowing this, is it worth arguing about whether it is possible for lice to appear in often nervous, but socially prosperous people? Oddly enough, yes. That's just the reason - not stress at all.

Nervous lice - is it a myth or reality?

What amazing stories about the appearance of lice on a person have not been invented by the people! For example, about the fact that louse eggs, like a virus, are invisibly present in the upper layer of the skin on the head. Allegedly, when a person is in calm state, lice do not remind of themselves. But it is worth living for a long time in a state of nervous overstrain, as insects begin to become more active and bother their carrier.

IN modern society it is impossible to relate to such a theory otherwise than as a myth or a relic from folk signs. After all, people have long noticed one of the obvious signs that appears both with stress and with lice infestation: on a nervous basis, there is almost always a burning desire to scratch your head, and with pediculosis this desire becomes even more intrusive. Therefore, not only in the wilderness, but also in cities, among the educated population, and today many people are looking for the cause of infection with pediculosis in the stresses experienced. Wrong, of course.

On a nervous basis, the scalp can unpleasant to itch and itch, but this is a sign that the immune system is weakened, and it's time to treat the scalp. So dandruff or psoriasis can appear with outwardly clean hair.

Infection with lice can be confidently ascertained only if, during a visual examination of the head, translucent nit eggs are visible on the hair in the form of small grains, as if glued to the hair. There are a lot of them, but running insects are visible on the scalp with the naked eye? Probably, with such a neglected physical condition, the head cannot help but itch!

The results of numerous medical supervision And scientific research they confidently say one thing: only on nervous grounds, lice do not appear and even the connection between these phenomena cannot be proved. It's time to part with this wild myth and turn to the social causes of pediculosis.

Causes of lice

The only possible way of infection with pediculosis is physical contact with its carrier. For this to happen, at least the contact of infected hair with healthy hair is necessary. This happens very quickly during games, wrestling, sexual intercourse, involving the close embrace of partners. It is not at all necessary to communicate with or be a homeless person in order to catch lice (as some are sure).

Lice are often found in their hair (or in their loved ones) and socially prosperous citizens. It is enough just to go to public transport at rush hour, huddled side by side with a "pediculosis" passenger. The risk group, first of all, includes those who wear long flowing hair: it is easy to hurt anyone with them and imperceptibly to themselves.

Fans of trying on other people's clothes, hats, changing towels should also be seriously wary. All foreign objects that are in close contact with the head can help lice.

You should not sin on domestic animals, from which supposedly lice can pass to humans. This is impossible just because the insects that live in animal hair live only in it, and the human head louse, accordingly, does not pass to animals.

If a child from a prosperous family after a vacation in a country camp needs treatment for pediculosis, this means that elementary hygiene standards were not observed in the detachment. Children not trained in the rules of care own body, easily use other people's combs, change hair ties or hairpins, change unwashed costumes and hats, fur props during theatrical performances. Should we be surprised at the appearance of lice after this?

Lice can stay in water for a long time, which is why infestations in public pools are so common. If lovers of swimming there against all the rules enter the water without a swimming cap, then there is no guarantee that they will not catch lice while swimming. It is impossible to know for sure if there were any "pediculosis" among the previous visitors to the pool.

Speaking of pubic or body lice, one should pay attention to the peculiarities of their name, in which lies the reason for their occurrence on the human body. Pubic lice can be infected from contact with a sexual partner who is a carrier of this trouble, or by swimming in stagnant open ponds with stale water. The clothes louse lives on unwashed, dusty things and clothes that are in close contact with the body.

Thus, the spontaneous "genesis" of lice on the human body without close physical contact with the carrier is unthinkable!

How to protect yourself from lice?

To protect yourself from pediculosis once and for all, you need to follow the basic rules of personal hygiene:

1. Do not give your personal belongings (towels, hairpins and hair ties, hats, hats, baseball caps and similar headwear, underpants) into the wrong hands and do not use other things that are in close contact with the body.
2. Do not go to bed on a pillow if there is a pillowcase on it after a stranger (for example, in a hotel or after an overnight guest).
3. Do not allow your hair to come into contact with strangers, keep them in a tidy condition (put them in a smooth hairstyle or wear a shorter haircut, do not be in in public places simple-haired).
4. Swim in the pool, protecting your head with a special cap. Do not swim in dirty natural waters.
5. Keep clothing and personal items clean and tidy.

If these simple rules are strictly observed, then you can not be afraid of infection with lice. And, of course, those who are prone to nervous strain should not be afraid of this scourge. In the twenty-first century, it is strange to follow popular speculation and neglect the advice of experts.

Theories of appearance are different, but they are all far from the truth. This should be understood by everyone who has such a problem. Scientists have long explored this fact and identified all the causes of lice and stress among these reasons is not.

A child, just like an adult, cannot develop lice from stress. The following are the reasons why a child can become infected with head lice.

From what lice appear on the head - the causes of the appearance of lice in humans

The main causes of pediculosis infection are:

• Use common subjects hygiene. One comb for two, especially for kindergartens, schools and camps. When using a pillow, when children often change places, using one towel, wearing someone else's clothes, hats. In this way adults and nits are transmitted.
• Close physical contact. In this way, you can get infected everywhere. Most often these are kindergartens and schools, children often play with each other in close contact.
• You can pick up such insects when visiting public saunas or baths, in cheap hotels and even in transport, especially during rush hour.

Lice Symptoms

It is almost impossible to determine where the lice came from, the period of incubation and living in a new hair is about two weeks, after another two weeks the female will begin to lay eggs. If a nit appears in the hair, a person is not able to feel it, it is very small, only after about three weeks you can feel it under your fingers.

Characteristic signs of pediculosis:

• Rash on back of neck, bite marks.
• The appearance of nits in the hair, especially behind the ears and on the neck, are yellowish crumbs 1 mm in size that are well attached to the hair.
• The main symptom of pediculosis is itching. Lice secrete a secret from the salivary glands, which, when bitten, does not allow blood to clot quickly, this irritation and causes itching.

Pediculosis is often confused with other diseases that cause itchy scalp. These diseases include psoriasis, dermatitis, allergies and neurosis. Consider their symptoms to remember the differences.

Psoriasis

Itching appears with severe stress and quickly passes, the disease has an undulating course. If the patient does not yet know his natural diagnosis, he may have a suspicion of pediculosis.

Dermatitis

Dermatitis is not related to such insects, it is accompanied by peeling and itching of the scalp. This disease is not transmitted.

Allergy

Allergies can appear during times of stress and are accompanied by itching, which is the main cause of insects.

Neurosis

On a nervous basis, a person can simply scratch his head, and because of this, it seems that lice have attacked.

If you find any signs in yourself or your child, even remotely resembling pediculosis, you should immediately examine the head and consult a specialist.

Science has proven that the immune system suffers from human nervous experiences. Negative emotions weaken the immune system, the body is not able to actively resist the development of bacteria and viruses. environment to suppress their development. A person becomes defenseless against the attack of various diseases. Scientists rightly believe that stress is a provocateur of the activation of the development of cancer cells. Are there lice from nerves, can negative feelings and experiences become a source of pediculosis, let's try to figure it out.

There is an opinion that pediculosis can appear from stress

Educational program about pediculosis

Among the myths about the relationship between the state of emotional burnout of a person and defeat nervous people Pediculosis can be divided into the following versions:

The scientific approach suggests that a person who is faced with pediculosis should know the following truths:

Ways of infection

• physical contact (when hugging, joint activities, games, various types of wrestling, kissing, visiting crowded places, contact in public transport);
• common use of things and household items (towels, combs, hairpins, hats, clothes) can also become a source of infection not only for head lice, but also for body lice;
• when swimming in stagnant reservoirs, hygiene procedures cause charging;
• may appear after visiting public baths, saunas, staying in cheap hotels with low level compliance with sanitary standards.

In children from 4 to 12 years old, pediculosis is more often diagnosed. They appear in them not from nerves, but because this age is characterized by the most active tactile contacts with peers, which contributes to the active transmission of the pathogen and more frequent cases of infection.

Based on the reliability of the arguments about the illogicality that lice can start from nerves, one must still find out why such versions and myths appear.

The only logical explanation is the assumption that the patient is being misdiagnosed. Often, skin diseases such as dermatitis, allergies and psoriasis, accompanied by redness, severe itching, are mistaken for head lice. Treatment in such cases can be chosen incorrectly, and it aggravates the patient's situation.

Transmission of head lice through contact with a patient with head lice

Lice breeding

They reproduce actively. Individuals capable of reproduction appear as early as two and a half weeks after the nits have been deposited. Even under adverse conditions, after a month, the newly appeared louse is able to actively reproduce offspring.

The reality should be stated that 50–60 days after the colonization of even one individual, a whole population of lice, regardless of whether a person is under stress or not, will inhabit the human body.

Choice of treatment

The right decision in the choice of treatment is to consult a doctor. Lice do not disappear on their own. It is necessary to start treatment immediately. There are many modern tools. The dermatologist will help to eliminate the problem by prescribing the necessary drug.

Opinions about whether lice can appear from stress have nothing to do with a scientific approach to the problem, so they are absurd and far from the truth. Scientists have never found evidence to support whether there can be lice from nerves.
