Infection with head lice, or, scientifically, head lice is considered by many to be something shameful, a sign that a person does not follow the rules of hygiene, does not wash, does not keep himself or his child clean.

However, this approach is completely wrong - it is easier to catch head lice, especially for children, and it is much easier to get rid of it today thanks to a large selection of pharmaceutical drugs. Unfortunately, there is no immunity to head lice, and infection can occur multiple times.

What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>

Let's figure out what lice is and how to deal with it, and at the same time we will try to find out if lice can appear on nerves.

What is a head louse

Head lice (lat.Pediculus humanus capitis) live in the hairline on the head of a person, in his hair, mustache and beard. In addition, they are able to live for up to two days (but not more) without food on personal items (hairbrush, towel, hats).

The length of an adult male is 2-3 mm, females reach a length of 4 mm. After fresh blood has been absorbed, the lice's gray body color changes to red or purple. During the day, the parasite drinks up to 1.2 ml of blood in 2-3 doses.

Unlike body lice, head lice are less dangerous to humans, they are not a carrier of diseases such as typhus. However, itching caused by saliva getting into the wounds leads to irritation, and the likelihood of infections getting through the damaged areas of the scalp increases.

Head lice breed under favorable temperature conditions all year round. An adult female lays up to 100 eggs during her short life of 27-46 days. The entire cycle of development of an ectoparasite from an egg (nit) to an adult insect takes place on the host and lasts about 20 days.

Head lice are wingless insects that can only distinguish light from darkness. Therefore, their main sense organ is the sense of smell. Lice can neither fly nor jump, but they move quite fast: at speeds up to 23 cm / min. Therefore, they are able to quickly change the owner, having moved from the head of a patient with head lice to the head or clothes of an uninfected person.

Lice from nerves myth or reality

Many people believe that head lice can appear on a nervous basis: for the time being, they are either in the form of larvae, or in a dormant state, and when a person is very nervous, they wake up and reproduce.

All this is nothing more than a myth. It has been scientifically proven that lice appear only with direct or indirect contact with a patient with head lice. Direct contact means the contact between the hair of a healthy and sick person, or lice getting on the clothes of a healthy person, from where they quickly find their way to the head. But there is also indirect contact:

  • Using personal belongings of an infected person (hairbrush / brush, towel, headgear, hairpins, etc.):
  • Use of bed linen, in particular, pillows after a patient with head lice;
  • Headrests on public transport and other surfaces that may have lice or nits.

The myth of the appearance of lice on a nervous basis most likely arose due to the fact that stressful situations really cause a variety of diseases, and when a person cannot understand where the lice came from, he assumes that negative experiences caused them. In addition, the symptoms of itching and head lice are very similar.

Parasite eggs

The transmission of parasites is facilitated by being in large groups, mass gatherings of people.

It is easiest to get lice infestation in the subway, sauna, hospital, swimming pool, hairdresser, even in the elevator. The main way lice move is by running, which is why head lice is so easily transmitted.

It is enough to touch the infected head with clean hair.

Often, children who, due to close communication in the children's team, are especially susceptible to this disease, become the source of infection of the whole family with head lice.

However, oddly enough, there is a grain of truth in the connection between the "nervous soil" and the appearance of lice, and it's all about the smell.

From the many nearby candidates for the role of master, they choose those whose smell attracts them the most, and these are people in a state of stress.

Moreover, we are not talking about ordinary experiences, but about situations accompanied by a severe nervous breakdown. Indeed, during a period of severe stress, immunity drops sharply and certain hormones are produced. There is a theory that it is a special smell, the appearance of which is promoted by the release of "stress hormones" - adrenaline, norepinephrine - and attracts lice.

However, the spontaneous appearance of lice in the absence of a carrier is impossible. The susceptibility to infection with head lice lies only in the greater vulnerability of people under stress when they are transmitted from an existing carrier.

Can a child have lice on a nervous basis?

According to statistics, every fifth child in the world has or is sick with head lice. Children are considered a risk group in relation to head lice, since their body is much weaker than an adult, moreover, they are less picky in contacts. However, infestation with head lice in children occurs in the same way as in adults.

The child's body is also not adapted for the hidden habitation of lice, like an adult, so this problem cannot appear only due to stress. Regardless of the patient's age, the answer to the question whether there are lice from nerves is unambiguous - this cannot be.

How to treat head lice in humans

Head lice can be dealt with quickly and efficiently with the correct use of antiparasitic agents, so carefully read the instructions for each drug.

But we will start with folk remedies, which are far from harmless to the body, especially children.

Lice have long been removed with kerosene and vinegar, but they often cause chemical burns to the scalp, especially if the proportions are incorrectly calculated.

If the substance gets on the mucous membrane of the eye, mouth or nose, then the patient is guaranteed serious problems with these organs.

The vapors of kerosene and vinegar are highly toxic, especially for children and pregnant women. Such folk remedies also have a detrimental effect on the hair itself: they change their structure and color.

In this list, we can separately note the ancient remedy for the treatment of head lice - hellebore water. This is an alcoholic tincture of the roots and rhizomes of Lobel's hellebore.

The alkaloids in this solution have a neurotoxic effect on lice and nits. Also, hellebore water has antimicrobial and anti-inflammatory effect. However, it is categorically contraindicated in children under 2.5 years of age, pregnant and lactating women, as it has a teratogenic effect.

Nowadays, there are a number of modern anti-lice preparations in the form of shampoos, aerosols, emulsions, creams. Each such product sold in pharmacies is accompanied by detailed instructions that must be strictly followed, especially given the restrictions regarding children, pregnant and lactating women.

However, when these agents are applied more than three times, the parasites acquire resistance to them. In such cases, it is possible to remove lice only by combing:

  • Hair is well washed, slightly dried.
  • Conditioner is applied to slightly damp hair.
  • Combing is carried out first with a comb with large teeth, then - combs with small teeth (for reliability, cotton wool should be strung on it). Rinse the comb periodically.
  • Dry your hair and repeat the brushing procedure.

An integrated approach is important in the treatment of head lice. It is necessary not only to destroy the adult, but also its eggs - nits. All family members, even if they are not found to have lice, are treated on the same day.

Anti-lice drugs are divided into several subspecies:

  • Medicines containing permethrin - the most famous insecticide;
  • Medicines based on other antiparasitic drugs (fenotrin, fenthion, etc.);
  • Means that envelop and suffocate parasites (with essential oils and dimethicone).
