What is the lethal dose for humans? Lethal dose of coffee

Not all of us know that the use of certain products familiar to us can be fatal to humans. These include: alcohol, caffeine, salt, and even water. It is important to observe the measure in everything. It would seem that the human body in a lifetime should have time to adapt to everything, but this is far from the case. One of the most harmful substances, which most people in huge quantities eat every day, without knowing it, is salt.

We are all used to hearing about salt every day, but few of us have thought about what it is, what benefits or harms this substance brings.

Some with full confidence argue that there is a certain lethal dose of salt for humans. It is worth looking into this issue. (or the kind that a person is used to using in food) is a natural mineral substance. Its first extraction was carried out many centuries ago. According to the chemical content, it can be said that salt is sodium chloride in the form of crystals. It includes 60.6% chlorine and 39.4% sodium. Salt is highly soluble in water. Despite the fact that many are inclined to believe that a lethal dose of salt does exist, it is primarily in moderate amounts is the basis of human life.

Properties and functions of salt

Salt, which is habitual for us, is the most important food additive for humans. It is usually sold in powdered form. It happens that in table salt there are some additives that can only change its color and taste, but not the main properties.

Other names for salt: table, stone, food. Or such a chemical name as sodium chloride. In modern production, they began to prepare salt with various additives: iodine, fluorine, magnesium, calcium and others. Many housewives will note one more of her useful property- the use of salt in canning. Thanks to this, vegetables and fruits can be stored in jars. long time and delight us with its taste and benefits on cold winter evenings. Despite the fact that there is an opinion that there is a lethal dose of salt for humans, the substances contained in it are vital for the body. For example, sodium, found in salt, constantly maintains right level osmotic pressure, acid-base balance, water-salt exchange human body. Due to the optimal sodium content, the muscles of the heart, intestines and kidneys work well, nerve endings. Chlorine is also important for the body: it breaks down fats, removes urea, supports the functioning of the central nervous and reproductive systems, and positive influence on bone tissue.

The benefits of salt for the human body

It is important to know that salt is not formed in the human body. It must be supplied in the required quantity from external sources. Salt is completely absorbed small intestine, and is derived using sweat glands, intestines and kidneys. Here it will be relevant to say about a person who can easily occur with excessive loss of water (diarrhea or vomiting). In this case, it is even possible. Therefore, with such a diagnosis, it is urgent to replace the lost balance of water and the salt contained in it. Of course, there is a lethal dose of salt for humans, but a moderate amount of it, eaten, is the main source of chlorine and sodium in the body. If these substances in organs and systems human body becomes insufficient, he has the following symptoms: general weakness, tachycardia, low blood pressure, involuntary muscle contraction, etc.

Is salt used in medicine?

While mankind is "puzzling" over the solution of the question of what is the lethal dose of salt, it is perfectly used for the treatment and prevention of numerous diseases.

Eg, colds the nose can be cured by rinsing it with a solution sodium chloride. This not only helps to moisturize its mucous membrane, but also kills numerous viruses and bacteria that have settled in it. Salt water enemas help a person cope with constipation, as they make the intestines work. In general, table salt stimulates the digestive tract, improving digestion by increasing the production of gastric acid.

Types of table salt

The modern industry engaged in the production of products began to supply salt of unknown brands and types to the markets. Its cost is sometimes significantly overestimated. Is it justified, is such salt useful? And how much can you eat? A lethal dose of salt, whatever it looks like, still exists, so you shouldn’t get carried away especially.

According to the method of extraction, there are several types of salt:

evaporation: extracted from the bowels, then water is evaporated from it;
stone: mined in special quarries with appropriate equipment;
self-planting: such salt itself precipitates, it remains only to be collected;
garden: evaporated naturally at the bottom of salt lakes.

If we talk about the types of salt based on artificial additives to it or special treatments, they distinguish:

dietary - has a rather specific taste;
"Thursday", "Papuan", Himalayan, and many others.

Should food be salted?

There is an opinion that three tablespoons of salt is a lethal dose for a person that can cause irreversible processes in his body. It cannot be said that, having consumed such an amount of this product, one can die, but harming the body, and quite seriously, is easy. And to avoid such disastrous consequences, you need to know normal dose salt for him.

It is generally accepted that this is - 1 teaspoon of salt per day (this is approximately 11 grams of sodium chloride). In those countries where the climate is much hotter and less humid, sweating among local residents is increased, the need for a daily dose of salt increases significantly, almost 2 times (25-30 grams per day). Well, now think about how much edible salt per day you use specifically. Most likely, this figure is much higher than the norm, and it can even be referred to as a lethal dose of salt, provided that you suffer from any diseases in which this product is contraindicated. In other words, the person in this case is just slowly killing himself. By the way, the calorie content of salt is reduced, it is close to zero.

Children's body and salt. pregnancy and salt

We have already found out that salt is necessary for the human body. She participates in metabolic processes and vital functions.

Therefore, both the child and the pregnant woman need enough salt. But, here are some minor clarifications:

With established breastfeeding the baby with mother's milk receives the right amount of salt along with other nutrients and vitamins. Therefore, the first complementary foods do not have to be salted. Of course, with the growth of the child, with an increase in the need for minerals salt should be added to his food, but in moderation.
Pregnancy is special condition, in which the body for nine months is responsible for the growth and development of the baby. Therefore, the need for salt in women in interesting position increases significantly. Of course, you need to know the measure, that is, if edema occurs, reduce the amount of sodium chloride consumed. But also completely exclude from your daily diet salt for pregnant women is strictly prohibited.
The lethal dose of table salt for babies and expectant mothers is somewhat different, but it is, so do not give your child a lot of sodium chloride, as an unformed body may not be able to cope with its excretion.

How much salt is detrimental to an adult?

This question has been asked by scientists and physicians around the world for many years, trying to find the most accurate answer to it. So, let's discuss how many tablespoons of salt is a lethal dose for one person? After all, we use it per day in large quantities. Still, it is customary to talk about grams of salt that can harm the human body, and they make up 3 g / kg of weight. That is, if the average person eats a quarter of a pack of table salt (250 g), he will die. Yes it is. Especially if at the same time he did not use the proper amount of liquid. And ate it in one sitting. The pressure will immediately rise, edema will appear, pulmonary and cerebral edema will occur, in short, death you are provided.

salt poisoning

Of course, in this case we are talking about a daily violation in the amount of sodium chloride consumed. People say that 3 tablespoons of salt is a lethal dose. But is it? It is difficult to apply this norm to each specific person, because we all have different weight and growth, and the distribution of all substances used in the body of a single person is different.

Therefore, scientists are inclined to believe that the lethal dose of salt for a person is 3 g / kg of body weight. These norms were obtained by conducting the necessary experiments on rats. Of course, it is difficult to compare animals and humans. Usually the first of them are much easier to be poisoned by salt, since they do not consume the proper amount of water per day. This only worsens the situation that is detrimental to their body. How to understand what happens in our body when an excess amount of salt gets there? Immediately, the pressure rises sharply due to a change in the composition of the blood. The person feels very bad. Dehydration sets in, work is disrupted nervous system. The result of these irreversible consequences: the death of the human body due to insufficient intake of its tissues and organs the right amount oxygen.

Salt is a life-threatening habit

It turns out that the statement “3 tablespoons of salt is a lethal dose” is not entirely true. Therefore, you must calculate this amount specifically for yourself, based on your weight: 3 g per 1 kg of a person's weight. Get used to eating salt in moderation, and then overweight, edema, increased arterial pressure you will never be disturbed.

Remember that in any business it is important to know the measure. This also applies to the use of salt. It is very important for your body, one might say, vital. But its excessive use in the end is capable of destroying a person.

IN modern life it is very important to know the measure. Paracelsus, the founder of modern pharmacology, expressed this very well in his quote “Everything is a poison, everything is a medicine, and both determine the dose.” Any substance in the world has its lethal dose.

Lethal dose of alcohol

Alcohol is, of course, not a vital product, but many people use it quite often, with or without reason. The lethal dose of alcohol for a person is 6-12 grams of alcohol per kilogram of body weight. To make it clear, these are three liter bottles in one, but your own body can save you by dropping toxic substances (vomiting, diarrhea, etc.). But there are curious cases, such as in 2004 in Bulgaria in the city of Plovdiv, a man was hit by a car, 9.4 ppm of ethanol was found in his blood (a lethal dose is considered to be 6 ppm). Here's the paradox, he was hit by a car and there was a lethal dose of alcohol in his blood, and he recovers in a couple of days.

Lethal dose of vitamins

All vitamins can be fatal to humans if consumed in large quantities. Lack and excess of certain vitamins are equally harmful to the body. For example, vitamin A deficiency will lead to increased hair loss, and hypervitaminosis to poisoning. Daily doses of any vitamins in without fail indicated on the packages.

Lethal dose sunlight

For several years now, there has been a trend of abnormal heat in the world, even in the north people are aware of how dangerous the Sun can be. Even in the last century, they thought that the more you are in the Sun, the better. But it has already been proven that excessive exposure to the sun leads to skin defects, decreased sexual function, development oncological diseases and death. The lethal dose in the sun is 8 hours.

lethal dose of nicotine

You think nicotine is found only in tobacco, you are deeply mistaken, it is found in tomatoes, potatoes, bell peppers and eggplants. But the concentration in the products is absolutely not harmful to humans, so do not bother.

Nicotine is a very strong poison. The lethal dose of nicotine for a person is 0.5-1 mg per kilogram of weight, which was more understandable, this is about 100 cigarettes at a time.

lethal dose of salt

No living being can live without salt. Our daily rate salt is only 1.5-4 g. If you do not use salt, then muscles will begin to die, the work of the stomach and heart will be disturbed, as well as the psyche will be disturbed and there will be constant depression. Complete absence salt in the diet will kill a person in 10 days.

Excess salt is also very dangerous. The lethal dose of salt for a person is 250 g. Death will be very painful, as there will be a lot of swelling.

Lethal dose of caffeine

Caffeine is found in coffee, tea, energy drinks and cola. In a small amount, caffeine causes a feeling of cheerfulness and a surge of strength, although after 3 hours this is all replaced by lethargy and fatigue. A lethal dose of caffeine is 10 grams, translated into liters, this is 4.5 liters of coffee.

lethal dose of water

Water is life. Everyone knows it! Nevertheless, she can be poisoned, even if she is spring. Too much water leads to overhydration - this is a violation of all body functions and further death. To achieve this, you need to drink more than 7 liters of water per day. Of course, water poisoning is rare, but it does happen. So in 1995, schoolgirl Lee Bette drank Ecstasy at her own birthday party, and then 7 liters of water and died after 4 hours.

In 2004, in Springville, USA, a mother forced her 5 year old daughter to drink 5 liters of water as punishment. The result is a mother in prison, the child died.

January 2007 radio station KDND in Sacramento, USA holds a competition called "Don't pee - get game console". One participant drank 7.5 liters of water and died two hours later, and the girl who won the competition remained disabled for life. Lawsuit filed against the radio station

Sleep disorders lie in wait for any person, regardless of age. The reasons are different: stress at work or at home, poor performance at school, unhappy love or upcoming life changes. Problems accumulate during the day and in the evening they deprive you of sleep. And then comes the turn sedatives. Let's figure out what is the lethal dose of sleeping pills for a person in tablets, why it is better not to buy medicines without a prescription and whether there is effective medicine without getting used to.

No matter how scary it is to realize, even the popular “No-shpa” can lead to death. An overdose of any drug is dangerous for its consequences. That is why all pharmacists and doctors strongly advise you to remove any drugs away from children and carefully read the instructions.

Over-the-counter products that are directly life threatening in overdose - all sleep products containing active substances: doxylamine succinate, phenobarbital, barbiturates, benzodiazepine. These may be medications:

"Dimedrol";
"Suprastin";
"diazepam";
"Clonazepam";
"ReSlip".

This list may include many other harmless remedies for allergies and colds, as well as tranquilizers. Taking them not according to the scheme, a person may simply not wake up.

It is important to know! But not always an overdose of sleeping pills is a fatal outcome. Most often, the patient's receptors for hearing, vision, movement are blocked - he turns into a "vegetable".

Overdose of sleeping pills: death

Is it possible to die from sleeping pills at all, or is it a myth? When combined various conditions, negative prerequisites - perhaps. The risk group includes people with high blood pressure, diseases of cardio-vascular system, with mental lability and CNS disorders.

Possible causes of overdose and poisoning

The first reason is a mistake. An aged patient does not always remember exactly how many pills he took and whether he took at all. As a result, 2-3 doses are drunk, which entails the danger of death.

What other reasons could there be:

A deliberate desire to end the troubles in one's life.
Children who find pills can take a lot of them.
Poisoning due to the fact that drugs are washed down not with water, but with alcohol.
Connection of incompatible drugs.
Bringing a person to murder by poisoning large doses drug.

Attention! It is worth remembering that death can occur even from taking sleeping pills with Aspirin - not every drug interacts with this harmless medicine.

Stages of poisoning and symptoms

Death does not occur immediately, first there is an active poisoning of the body, while the person goes through several stages. Each stage has its own characteristics. Consider all the stages and symptoms:

Increased drowsiness is stage I. Symptoms: inhibited reaction, impaired orientation in space, possible diarrhea, vomiting. At this stage, a person is still contact, can respond to external stimuli.
Superficial coma - stage II, called medium-severe. The patient loses contact with the outside world, consciousness is disturbed, the person stops feeling pain, there is no reaction to stimuli, reflexes are depressed. Often there is hypersalivation leading to aspiration of saliva into the Airways- the patient will choke, while not being able to ask for help.
deep coma - III stage, which is called extremely severe. Here, an overdose of sleeping pills has the most severe consequences: cerebral edema, damage to cortical structures, the absence of all reflexes, respiratory depression, blood pressure decreases, and cardiovascular failure in dynamic progression. If such a patient is not helped, his life is in serious danger.

The last stage is considered terminal - doctors diagnose clinical death, and if the efficiency resuscitation small, then biological death.

List of consequences

An overdose of drugs does not always lead to death, much more dangerous consequences with which a person may have to live on. Let's talk about them in more detail.

So, the consequences of an excessive dose of sleeping pills:

If you take sleeping pills constantly, addiction occurs. And this leads to the following consequences:

Insomnia. The patient gets used to a constant dose of drugs and no longer sleeps without them.
Stress arising from the lack of night rest. This leads to instability of the psycho-emotional background, which leads to nervous disorders. varying degrees gravity.
Aggression. This is a symptom that also develops against the background of insomnia.
Decreased activity, mental skills. A person is faced with the fact that he does not succeed in things with which he previously coped with ease. It also causes bloating negative emotions and leads to dangerous consequences.
Death. IN medical practice enough occasions when a person taking an evening sedative drug didn't wake up in the morning.

Attention! It must be understood that the consequences of excessive use of sleeping pills can be: destruction of blood circulation and death of the lobes of the brain, irreversible changes in the network of blood vessels, life-support organs, hypertension, myocardial infarction, strokes and other unpleasant diseases.

Fatal outcome: what should be the dose

So, how many sleeping pills do you need to take to die? It depends on the type of drug, age, individual features patient. For some types, one tablet will work, while for others you will have to drink a handful of pills.

Attention! According to statistics, death is possible if you drink a 4-fold dose. Also death inevitable when the drug is taken by a person drinking alcohol. A teenager under 14 years old, a patient over 65 years old with high blood pressure can drink the medicine in the indicated dose, but get not sleep, but death. The child, due to an unformed immune response and rapid absorption, old man due to exacerbation of cardiovascular disease.

Fatal overdose: certain types of drugs

What happens if you drink a lot sleeping pills Are there drugs that are lethal? Yes. The list of dangerous drugs is quite wide. We list the main types:

"Donormil". A drug with a small list of contraindications. The lethal dose is 10 capsules, but the amount is calculated individually. For some patients, a dose of 3 pills is enough if washed down with alcohol.
Melaxen. A high dose is considered to be 4 times the norm - this is a pack of 10 tablets.
"Phenazepam". The strongest tranquilizer. A dose of 10 mg leads to death.
Zoloft. New generation antidepressant. When the dose is exceeded by 5-6 times, severe poisoning, and when washed down with alcohol - death.

Easy death from sleeping pills: truth or fiction

Let's just say that dying always hurts. Regardless, the capsule is taken potent agent, which was washed down with alcohol or the drug was drunk in a large dose.

Complications are determined only by the type of drug components. In some cases, before death, a person feels suffocation, high pressure"pounds" in whiskey, profuse vomiting and diarrhea spoil " beautiful picture" of death. Let's add here convulsions, convulsions that fetter the body and do not allow to move, breaking consciousness. Only then comes a hypnotic sleep, leading to a coma, and then death.

Emergency life saving

If one of the relatives or friends takes dangerous drug, you need to keep track of how much the person drank the medicine. It is especially important to control the dosage in older people who are prone to forgetfulness. It would be useful to learn the symptoms that indicate that the drug has been drunk a lot.

In any case, without calling the brigade emergency care not enough. It is important to remember the name of the medicines and not throw away the packages from under the products, so that doctors can start detoxification as soon as possible and minimize strong negative effect from poisoning.

First steps at home

While the ambulance is on the way, a number of independent measures should be taken. In particular, if a person started using sleeping pills 30 minutes ago and is still conscious, you need to:

give as much water as possible to drink;
induce vomiting;
give sorbents (activated carbon);
pour sweet strong tea or milk.

If a person is unconscious, the algorithm of actions:

open your mouth and check for pills - a large number of impossible to swallow immediately;
if there are signs of breathing, palpitations, put the patient on his side;
vomiting has begun, you need to make sure that the respiratory organs are not clogged.

Needed in cardiac arrest indirect massage. You need to know it if there is a seriously ill person in the house, whose treatment is carried out with injections or sleeping pills.

chances of survival

At timely assistance the result of poisoning may be reversible. It is only important that the right doctor or person who knows what should be done is nearby. With all other factors, there is also a chance to survive, however, severe brain damage and internal organs respond with a series of diseases, mental disorders and other troubles.

Attention! The consequence of poisoning with sleeping pills is not always death, most often it is disabled carriage, immobility or degradation mental abilities. This is what you need to think about before you eat a handful of pills at a time - not all drug products lead to instant death, more fatal consequences can occur.

Overdose prevention: important rules

In order not to die from sleeping pills, it is necessary to carefully study the instructions for use, where interactions with other drugs are written. The rules for preventing fatal outcomes are simple: limit access to medicines for children and the elderly with nervous disorders and strictly control the dose of the drug.

Conclusion

Sleeping pill poisoning is a serious condition that requires urgent health care. Every minute is important, the defeat may not lead to death, but to the development of complications of an irreversible nature.

And, of course, you should not lull yourself immediately with strong compounds. For example, the drug "Persen" has won excellent reviews, has few contraindications and helps with intermittent insomnia. If sleep disturbances are caused by single shocks, the day has passed hard and there is a blockage at work - do not rush to drink sleeping pills. There are safe homeopathic remedies, herbal preparations to help solve your sleep problem.

In our life, it is very important to observe moderation and proper concentration in everything. This was very accurately expressed by one of the founders of modern pharmacology, Paracelsus (1493 - 1541) in his famous phrase: “Everything is poison, everything is medicine; both are determined by the dose. Absolutely every substance, even the most indispensable and necessary for the continuation of life, has its own lethal dose, which, moreover, is not so great.

Lethal dose of alcohol

Alcohol, of course, is not vital necessary product nutrition, but many people love to use it as such, often completely forgetting about every measure. A single lethal dose for humans ranges from 4 to 12 grams. pure alcohol per kilogram of weight. Also, for an adult male, the presence of 5-6 ppm of ethanol in the blood will be a lethal concentration (1 ppm of a substance means that 1 ml of this substance contains 1 liter of liquid). Such a concentration can be achieved by drinking about 3 bottles of vodka in one sitting (unless, of course, the body’s natural defense works in the form of an urgent discharge of excess poisonous substance by all possible ways). But there are also funny cases. For example, in 2004, in a hospital in the Bulgarian city of Plovdiv, 9.14 ppm of ethanol was found in the blood of a pedestrian hit by a car. The test was repeated several times, and all the time a concentration many times higher than the lethal concentration was obtained. The most interesting thing is that the unusual patient soon recovered. Despite its toxicity, ethanol can be used as an antidote for poisoning with other alcohols (for example, methanol or ethylene glycol).

lethal dose of vitamin

Absolutely all essential vitamins for life are terrible poisons if consumed without measure. Sometimes both a deficiency and an excess of a particular vitamin leads to very similar external manifestations. For example, beriberi and vitamin A hypervitaminosis will have dry, rough skin And increased prolapse hair. The amounts of vitamins in which they are vital, as a rule, are very small, and the excess of these concentrations leads either to acute or to chronic poisoning. The doses in which vitamins can be taken are necessarily indicated on the packages of the drug, because in order to kill or very seriously injure yourself, one or two pharmacy packages are enough.

lethal dose of sunlight

After several years of regularly recurring “heat-waves,” even northerners know how dangerous the Sun can be. From the beginning of the 20th century, until about the 80s, it was generally accepted that the more time you spend in the Sun, the healthier you will be. But now it is already known for sure that excessive exposure to the Sun leads not only to purely external skin defects, but also to such “long-term” consequences as accelerated aging, decreased sexual function and the development of cancer (insufficient exposure to the Sun is also fraught with absolutely the same consequences).

Sunstroke is an extremely dangerous condition, it develops suddenly, and the mortality rate reaches 30%. Therefore, if being in the open sun, a person begins to feel unwell, it is better to play it safe and try to go into the shade.

lethal dose of nicotine

Nicotine is not only found in tobacco. There is quite a lot of it in potatoes, and in tomatoes, eggplants and greens. bell peppers. True, the nicotine contained in these plants does not cause harm due to its insufficient concentration.

Nicotine is the strongest poison not only for all warm-blooded animals, but even for insects. Sensitivity to nicotine different types animals is very different: for example, rats die when receiving 50 mg per kilogram of body weight, 5.9 mg is enough for mice, and for humans, a fatal dose is 0.5-1 mg per kilogram of body weight (for comparison, the lethal dose of the famous potassium cyanide is 1 .7 mg per kilogram of body weight). When smoking, most of the nicotine in the cigarette is simply burned off and converted into a less toxic poison. To kill yourself immediately, and not gradually, you need to smoke about a hundred cigarettes in one sitting.

lethal dose of table salt

No living being can live without salt. But daily requirement of this substance is extremely small - only 1.5-4 g. If the body experiences a chronic lack of salt, then bone destruction and muscle death begin, the work of the heart and stomach is disrupted, severe depression develops and others mental illness. The complete absence of salt in food (although this situation rarely occurs) can kill in about 10 days.

Excess salt is no less dangerous than its lack. The fact that "salt is a white poison" when there is too much of it has been known to everyone for a long time. For a person, a lethal dose is a single intake of about 250 g of salt. Death in this case will be very difficult, since you will have to die from numerous edema.

Lethal dose of caffeine

Caffeine is found in coffee, tea, cola and many other plants. In small doses, it causes a surge of strength and a feeling of cheerfulness, which, however, after 3-6 hours are replaced by increased fatigue, lethargy and depression. A lethal dose for a person is 10 grams of pure caffeine (provided that all of it enters the bloodstream). That is, in order to poison yourself to death, for example, with a good Italian espresso, you will need not only to drink about 4.5 liters of this excellent drink at a time, but also to thoroughly absorb all the caffeine that it contains.

lethal dose of water

Water is the basis of life. Everyone knows this. Nevertheless, you can not only drown in water - you can also get poisoned by it, moreover, absolutely clean, drinking water if you drink too much. If the body has received too much water, a state of hyperhydration occurs, leading to a violation of the water-salt metabolism, numerous disorders of all body systems and death. To achieve this state, you need to drink about 7 liters of water during the day.

Water poisoning is rare, but it does happen sometimes. For example, victims water poisoning become soldiers after grueling crosses in the heat. But there are also curious cases - for example, the English schoolgirl Lee Bett in November 1995, celebrating her 18th birthday, first took Ecstasy, and then drank 7 liters of water in just an hour and a half. Death came within 4 hours.

In June 2002, in the US city of Springville, a mother forced her 4-year-old daughter to drink almost 4 liters of water as punishment. The child died and the mother went to prison.

In January 2007, radio station KDND in Sacramento, California ran a surprisingly stupid contest called Hold Your Wee for a Wii. One of the participants in this competition, Jennifer Strange, who drank 7.5 liters of water, died without reaching the final. And the winner of the competition (Lucy Davidson) became seriously ill. As a result, relatives filed multimillion-dollar lawsuits against the radio station and won them.

lethal dose of electricity

There is no need to warn about the dangers of household electricity - almost everyone who uses electrical appliances sooner or later gets the opportunity to own experience learn that an electrical discharge can be very unpleasant. Get highly painful blow current in our time is possible, even without using any devices. This happens especially often in winter, when the air in the apartments is dried up by central heating, and sparks fall from clothes and hair with every movement. If the strength of the current passing through the human body current exceeds 1 mA, then this already causes a very discomfort. D.C 60 mA or 300-500 mA alternating power can lead to a malfunction of the heart (or restore the work of a just stopped heart).

To kill a person with an electric chair, a voltage of 2700 V and a current of 5 A are used. The voltage is turned on twice for minutes with a break of 10 seconds. It's usually enough to kill yourself. strong man. But on October 16, 1985, it took 5 such blows to execute William Wendyver.

Lethal dose of mosquitoes

A female mosquito, if not disturbed, can suck about 5 mg of blood from a person. For a person, the loss of about 2.5 liters of blood is fatal. It turns out that about half a million mosquitoes can “seize to death” a person. But in this case, most likely, death will occur much earlier from a reaction to the saliva of mosquitoes, which they inject during a bite (it is their saliva that causes itching, swelling and other reactions).

In order to die, it is not necessary to be a victim of a murderer or a suicide, it is enough to consume a lethal dose of any substance. Any substance can be dangerous for a person, even water, of which it, in fact, consists.

Alcohol

6-12 grams of alcohol per kilogram of human weight will be enough for the heart to stop. For the average man weighing 75 kg. - this is 0.67 liters of pure alcohol or 1.5 liters of vodka. However human body unique enough that you'd rather vomit than die.

In 2004, in Bulgaria (the city of Plovdiv), 9.4 ppm of alcohol was found in the blood of a man who was hit by a car. It is believed that 6 ppm is a lethal dose.

Sun

The sun can lead to skin defects, reduced sexual function and the development of other diseases. Bottom line: it is dangerous to stay under the open sun for a long time. So, for example, in order to die, it is enough to stay under the open sun without clothes for 8 hours.

Nicotine

Nicotine is not only cigarettes, it is also potatoes, tomatoes and eggplants, but there is not so much of it in the lower that it is deadly harmful. The lethal dose for humans is 0.5-1 mg. per 1 kg. weight. For the average person, that's 100 cigarettes at a time.

Without salt we will die, however daily dose- 1.5-4 grams, no more. Without salt, muscles will begin to die and the work of the heart will be disrupted. Absolutely without salt, a person can live 10 days. But if you eat 250 grams of salt at a time, then the whole body will swell and the person will die - it will be long and painful.

Caffeine

It is found in coffee, tea, energy drinks and cola. Caffeine gives an instant boost of energy, although the body begins to consume it from its reserves, and after 3-4 hours you will be tired and want to sleep. 10 grams of caffeine will kill a person, which is about 4.5 liters of coffee.

In Springville, USA in 2004, a mother forced her daughter to drink 5 liters of water as punishment for some misdeed. The result is deplorable. And in 2007, radio station KDND (Sacramento, USA) held an action under the slogan “Don’t pee - get game console". One participant drank 7.5 liters of water and died 2 hours later. And the winner remained disabled for life. The company was successfully sued.
