Only from nerves, without other causes and infection from other people, lice on their heads can not appear. Existing ideas that eggs or lice themselves are dormant in the scalp, while a person is calm, and begin to swarm and cause itching only with nervous excitement, are pseudoscientific myths that are illogical and not confirmed by any studies.
Nevertheless, speculation about how lice on a nervous basis appear are widespread, not only in the provincial area, but also among the urban, well-educated population. This should be treated as a remnant of popular beliefs.
However, the idea of whether lice can appear on the nerves, in some respects even has a connection with science.
I never understood when my grandmother told me where the lice are taken from a man on a nervous basis. No matter how nervous a person is, the lice themselves are insects, and they just will not appear. But at the university, that's exactly what happened. I broke up with my beloved, with scandal and tears, I was very upset, I started my studies, and started. I scratched my head, I sinned on an allergy, I could not sleep, and then I began to detect nits. A couple of times on the pillow found the lice themselves, and I had to go to my parents for a week to poison this muck with kerosene. Now I understand that lice from stress - this is quite real.
How do lice on your head actually appear?
Specialists-parasitologists have long found out how lice on the head and other parts of the body appear. The only way to get lice on a person's head or body is a direct transfer from another person. Usually such infection occurs at close intercourse, kisses, embraces, sexual acts, games, wrestling.
It is also possible to carry lice through hygiene and hair care products - combs, towels, hair bands, hair clips. However, this method is more rare and an important role in the spread of lice does not play.
On a note
The pubic louse can also be transmitted in standing water along the water - all lice are resistant to hypoxia and do not perish in water for two days. There are cases of infection of children with pubic lice in India when swimming on public beaches of rivers in poor areas.
The louse, who spends most of his life on clothes and underwear, can with this clothes and spread, provided that several people wear clothes. Even the head louse can be transmitted through fur caps.
There is an opinion that is not rejected by scientists, that a person in a state of emotional arousal is more attractive to lice. These parasites are guided primarily by the smell, and the nervous person is more active sweat glands and it produces a stronger and stronger flavor.
However, given the inability of lice and their inability to fly, their reaction to the smell of a nervous person can only be explained by their transfer from one host to another, but not a spontaneous appearance. Therefore, even if the dependence of the probability of transmission of lice from the nerves is present, then on the spread of these parasites it affects very little.
The main popular theory of whether lice on a nervous basis can get lunatic is based on the following:
- a quiet person lice and their eggs are dormant in the head, not showing any signs of themselves.
- Lice from stress appear, reacting either to thoughts in the head, or to a constant allocation of sweat, and immediately after the appearance begin to actively eat and bite the person.
Illogical in such a theory a lot.
Firstly, she does not explain how initially lice find themselves in the head and where they come from, nerves. After all, by inheritance they are not transferred, but if they are transferred from another person - why do they stop for a while?
Secondly, today it is known that lice can not starve for more than a few days. Accordingly, a dream in their head for many years is a scientific nonsense.
And, finally, it is not clear what a nervous person turns out to be so much more attractive source of food than a calm one, that on the last lice they can not even actively eat.
On a note
This theory has several options. Among them - the appearance on the head of the cones, in which the lice swarm. Allegedly, even photos of such cones are available. This is also a fiction: lice can not settle under the human skin. However, often another parasite - subcutaneous mites are confused with subcutaneous lice.
Obviously, such theories are peculiar atavisms of the people's picture of the world, which are gradually becoming obsolete. However, because of their existence, many people use the wrong ways to control parasites and even contribute to their spread.
Lice from stress: is it lice?
Another answer to the question, whether lice are from nerves, lies entirely in a different plane: lice from stress are not lice at all, but a common allergy or dermatitis on a nervous basis.
Indeed, the appearance of lice on the nerves can easily be confused with the signs of any skin disease on the head, giving off an itch. For example, psoriasis is characterized by itching with a wave-like intensity of manifestation. Most of all, he gives himself out at moments of emotional arousal. And before an experienced dermatologist accurately diagnoses the disease itself, the patient may feel that he has lice on nerves.
Dermatitis can also appear on the nerves, and lice to them have not the slightest relationship.
Sometimes for the appearance of lice on the nerves of the soil can be taken scabies, the causative agent of which are not lice, but mites. True, scabies are more often localized on the hands and on the body, but mites can also settle on the head. Here they are and live in the skin itself, not showing outside and causing severe itching during their movements. Of course, scabies also does not come from nerves.
To distinguish scabies from lice (infection by lice) can be due to the appearance of itching on that part of the body that is not covered with hair, as well as the absence of nits on the hair and visible points of bites.
In the photo below, traces of the presence of lice are visible - it does not matter, on the nerves of the soil there were combs around the bites or simply from the itching:
In another photo - the hand of a person infected with an itch mite:
However, to find out whether lice can be from nerves, or not, is not enough for a person already suffering from them. He needs specific instructions for action.
How should I be treated with lice?
For whatever reasons the appearance of lice is associated - on a nervous basis or indeed through transmission from another person - treatment should be started immediately.
In especially neglected cases, scalp, bitten and itchy, can be treated with soothing balms or lotions. But the first priority in infecting lice requires the destruction of the parasites themselves. They disappear - the signs of the disease will disappear.
Fighting lice is quite troublesome, but not difficult. Previously, the head of the infected was treated with kerosene and put on it for a few hours. Lice from this perish. Today, for the same purpose, special shampoos with lice poisons, toxic to insects, but harmless to humans, are used.
Sufficiently effective are also special combs against lice, which comb out and adult insects, and nits. However, if using kerosene or insecticide shampoo can get rid of lice in a few hours, then the comb will have to tinker for several days.
To combat pubic lice use special ointments and shampoos. In all cases of controlling lice, shaving of the hair cover is an effective measure, especially in the summer, when the head is exposed to active sunlight.
A few more myths about lice
The myth of how lice appear from nerves is not the only one associated with these parasites. There are still a few surviving beliefs, in which a large number of people believe more willingly than in the facts proved by biologists. For example, many are convinced that lice and nits are different insects. In fact, nits are lice eggs in special shells.
Proving, whether there are lice from nerves, some experts admonishly explain that lice appear from the mud on the very head or in the house. These theories are close to those that professed in ancient Greece, and today science convincingly proves that it is impossible for lice to self-grow from dirt.
There is even a theory that lice are original cancer cells that can appear in the body on nervous soil and die only with the death of the host organism. This tale is as ridiculous as it is terrible. And, finally, the people are very popular with lice . Many healers are convinced that special spells will be enough to rid the sick person of parasites. Obviously, no matter where lice on the body or head come from, it's impossible to drive them out with spells alone.
