Why do I use this particular toothbrush?

Well, it's simple and beautiful. And the bells and whistles that other brushes have are probably pure marketing, they are of no use.

Why this toothpaste?

She smells nice.

Why do I brush my teeth this way?

I'm used to it since childhood.

Why don’t I have interdental brushes, irrigators and other devices for cleaning my teeth?

Hm. Because life is too short for me to waste it on interdental brushes? I don't know, I didn't think about it.

If your answer is approximately the same, then this book is for you. Choosing the wrong toothpaste brings the day closer when your teeth will need treatment. Due to improper hand washing, you are more likely to get ARVI. By defrosting meat incorrectly (at room temperature, not in the refrigerator), you increase the risk of food poisoning. Every day we do many little stupid things of this kind. Simply because we don’t think about it. Simply because we are used to it.

Sometimes the opposite happens. We are afraid of something that is completely harmless (or almost harmless): scale, a microwave oven, or a monitor that supposedly kills our eyesight.

I tried to understand all this from the point of view of evidence-based medicine. Evidence-based medicine is good because it has the tools to provide a reasoned answer to the question “Why?” Why do professional dental societies recommend using fluoride toothpaste? Because in well-conducted studies, this approach has proven effective in preventing tooth decay. If such studies did not exist, then we would know that we know nothing. And this is also good: we would not be fooled by the ardent belief that only a paste with tea tree oil and ground pearls can protect against caries. “Where is your evidence?” - "There is none of them". However, due to the relatively small number of good studies, such verification of information is often unsupportive and leads to some confusion. But it’s still better to know that we don’t know something and come to terms with it than to blindly believe.

Together with Marianna Mirzoyan and Karina Nazaretyan - they are also medical journalists - in January 2016 we started a channel on Telegram (essentially a blog) called “Wet the Mantu”. The title may seem strange, but it has an important message. I think more or less all people who grew up in the USSR and Russia know that the manta sample cannot be wetted. This taboo sits firmly in the head, and few people even think that everything could be different. We want people to question such “well-known facts” and look for evidence. Because in the end it turns out that the mantu sample can be soaked, if you have a sore throat you even need to eat ice cream, and the meat cannot be washed before cooking.

There are not many decent sources with which you can check information. There are practically no of them in Russian, mostly in English, because there is no local medicine - there is world medicine, and the language in which doctors and scientists from all over the world share information is English. All manuals of professional medical societies, all scientific journals that meet strict requirements are in English. Scientific articles are collected in the PubMed.com database. But the fact of publication itself, of course, is not a sign of the quality of the article, and each article must be dealt with separately; this is a rather complex process that requires certain skills. Therefore, in medical practice, the guidelines of professional societies are more often relevant: based on the analysis of scientific articles, experts recommend how to prevent, diagnose, treat, etc. These guidelines can be found on the websites of the professional organizations themselves or on ClinicalKey.com. Useful fact-checked texts about a variety of diseases and conditions can be found at UpToDate.com and Medscape.com. These are all sources for doctors, nurses and journalists. Maybe even for advanced patients. For everyone else, for example, government websites MedlinePlus.gov (USA) and NHS.uk (UK) have been created - the information there is simplified. UpToDate also has a section for patients - uptodate.com/patients. There are other sites, but MedlinePlus works as an aggregator and links to almost everything decent. Using these sources, you can find answers to most questions about health.

I wrote this book based on the sites listed above, and also talked with doctors, looked at what doctors told my foreign colleagues, and checked every fact that seemed obvious. And if, while reading, you come across some strange statement, you can always look in the footnotes and familiarize yourself with the source. Some things you just don't want to believe, and...

“Afisha Daily” publishes the chapter “What to drink,” which talks about the dangers of water filters, the benefits of coffee and the pointlessness of “live yogurt.”

Daria Sargsyan

Medical journalist, editor of Meduza, co-founder of the telegram channel “Namochi Mantu”

If you don't figure out what kind of water to drink, you can make the wrong choice, and it will definitely lead you to the grave. Heavy metals will settle in the liver and destroy it, chlorine will eat the mucous membranes, and this scale, God, this scale - it is so disgusting that it cannot help but be poison. The water will slowly kill you if you don't figure out how to stay safe. And therefore, life without a water filter is the life of suicide. But - surprise! - there is no filter that would remove “all the bad” and leave “all the good”. “Raw” tap water can be drinkable, but bottled water can lead to diarrhea or stroke. How to figure it out? It's actually simple.

Tap

If you live in St. Petersburg, Adygea, Moscow or Stavropol Territory, then you are very lucky. At least for tap water. At least, this is what he thinks, who named these regions the best in his ranking. Another thing is that water, having passed through the pipes of your house, for which housing and communal services, and not the water utility, are responsible, can change its qualities: the pipes rust, and, in addition to iron salts, bacteria settle in them. There are also seasonal fluctuations in the composition of substances; they mainly become noticeable when snow melts, and water utilities do not always cope well with the increased load. As a result, the water becomes unsafe and sometimes tastes bad. At the same time, without reagents and special equipment, you are not able to determine which filter you need, because you do not know why your water is bad, if it is bad. You can, of course, install an expensive reverse osmosis system, but this way you will remove from the water, among other things, magnesium and calcium, which could still be useful to you, especially if you eat spinach, beans, nuts, etc. If you buy a reverse osmosis system with a mineralizer, then this is an even bigger expense, the meaning of which is not established if there is no water analysis.

That is, the filter must be selected strictly according to the indications. Like medicine. Water analysis is done in much the same way as urine analysis in network laboratories: either you bring the material to the laboratory, or a specialist comes to you for the material (if you plan to make claims to the water utility, it is better to choose the second option). There are different tests, and they mainly differ in the number of indicators that the laboratory checks. The largest ones are usually needed if the water is of dubious origin: for example, it comes from a well. You can also see what deviations Rospotrebnadzor usually finds in your region and select the analysis that examines this problem.

There are several basic methods:

a jug with a carbon filter (does not remove nitrates, bacteria and minerals; depending on the type of filter there are other restrictions);

ion exchange filter (if there is ferric iron or iron bacteria in the water, the filter will deteriorate);

reverse osmosis system (does not remove all organic and inorganic impurities);

distiller (does not remove some volatile organic compounds, pesticides and volatile solvents; bacteria may colonize internal elements of the distiller).

And don't forget to change parts of your cleaning system. For example, after the expiration of its service life, a pitcher filter will begin to wash out everything that it diligently collected From a letter from Vasily Litvinov, a bacteriologist at the independent laboratory “Invitro”.

In a good way, analysis alone cannot be done. The US Environmental Protection Agency should test the water every year for total coliform bacteria, nitrates, solids and pH, especially if the water pipes have been replaced or repaired (it may be better to do this during snow melt, when there is an increased risk of finding something in the water not that). It is also better to check the water if it has an unusual taste, smell or color. The agency advises testing for sulfate, chloride, iron, manganese, hardness and oxidability in this case. And it’s even better to do this every three years, regardless of the circumstances. If for some reason a baby will soon appear in the house, it is better to check the water for nitrates 7–8 months before and in the first six months of the child’s life.

This all most likely applies to cold water - you should not use hot water. Of course it meets the same standards as cold SanPiN 2.1.4.1074–01, but hot water promotes oxidation of pipes and growth in them, that is, its composition is more unpredictable than the composition of cold water.

If you decide to drink tap water but don't like the smell of chlorine, there are several ways to deal with the problem. “Settling: you can simply leave the water in the vessel for several hours so that the chlorine gradually disappears,” explains Igor Buzin, an employee of the Analytical Center of Moscow State University (Moscow). - Boiling: During the boiling process, chlorine quickly leaves the water. Whipping: you can beat the water with a mixer - with forced aeration, the chlorine leaves quite quickly. Jug filter against chlorine - also not bad thing From a letter from Igor Buzin».

There’s no point in eating scale from the kettle on purpose, but there’s no point in being panicky about it either.

As for boiled water, the kettle does not do anything particularly unacceptable with it. Boiling helps get rid of bacteria, viruses and protozoa, which is very healthy. In principle, many bacteria are not dangerous for humans, and the body can cope with some pathogens quickly and painlessly, but if there is a person at home with a weakened immune system (really weakened - chemotherapy, untreated HIV infection or something equally serious), it is better boil water.

About the scale that everyone is so afraid of, you need to know that it is relatively harmless: it is the deposition of calcium and magnesium carbonates. Some people even specifically buy such substances in tablets: these are antacids, remedies against heartburn. Although, it must be said, when taken regularly they cause side effects, but here, of course, you need to take into account the volumes: it is unlikely that you will have as much calcium carbonate in a mug of tea as in a tablet. That is, you shouldn’t deliberately eat scale from the kettle, but there’s no point in being panicky about it either. “In its pure form, scale has a cream color (with shades),” says Igor Buzin. - If the scale is red or has any other color shades, this means that there are some metals in the water that can color this scale. Thus, iron can color scale in yellow, red and ocher tones, and form veins and spots in it. Well, the rate of scale deposition and its amount will help to roughly estimate the content of hardness salts in the water.” You can boil water as many times as you like. The only consequence of this is a slightly higher concentration of substances present there. But there is nothing to worry about: in 1-3 times the water will not have time to evaporate so much that there is too large a portion of some harmful substance in one mug. To finally calm down, you can measure the volume of water before boiling and after (when the water has cooled) and see that it has changed, to put it mildly, slightly.

Bottled

Bottled water intuitively seems safe: it is probably tested better than the water that flows through pipes. In fact, there are problems with it: “We had to test bottled water more than once; sometimes in such water we actually found microorganisms that should not be in drinking water,” says Vasily Litvinov, a bacteriologist at the independent laboratory Invitro. “In my opinion, this is due to the fact that these products were counterfeit.” Rospotrebnadzor also regularly finds low-quality water, which it reports on its website. That is, if you are categorically not satisfied with tap water, but you like the taste of some bottled water and you plan to cook everything with it, from tea to soup, it may be worth having it analyzed.

In general, the main question is “bottled or tap?” is decided very individually. Perhaps drinking tap water is just more difficult psychologically. Science journalist Elizabeth Royt in her book Bottlemania Elizabeth Royte: Bottlemania. Big business, local springs, and the battle over Americaʼs drinking water. Bloomsbury, 2009 trying to choose a water source. In the end, she decides to drink tap water, albeit after installing a filter (although the analysis showed that there is nothing wrong with the water). “At this point, I have spoken to enough scientists and environmental experts to believe that the Brita (water filter. - Note ed.) has more psychological than physical benefits for me,” admits Royt.

Mineral water

Bottled water can be table water ( mineralization GOST R 54316–2011 less than 1 g/dm3), medical-table (mineralization - from 1 to 10 g/dm3) and medicinal (mineralization - 10–15 g/dm3). The last two terms are, it must be said, misleading. The labels say that mineral water is useful for gastritis, stomach and duodenal ulcers, diseases of the endocrine system, hepatitis, colitis, bronchitis, gout, obesity, etc. - the list seems endless. But try asking about these properties of PubMed mineral water. Or Medscape. Or UpToDate. PubMed will be the most talkative (the rest will simply remain silent). It contains many articles about the healing properties of mineral waters. Only these articles appear in journals like the domestic “Issues of Balneology, Physiotherapy and Physical Therapy.” No Lancet, New England Journal of Medicine, BMJ or any other publication in English (with rare exceptions). “With gastritis and stomach ulcers, mineral waters are practically meaningless,” says gastroenterologist, director and managing partner of the Rassvet clinic, Alexey Paramonov. - They are only slightly effective as a primitive antacid, since they contain soda. In those years when there was nothing effective except soda, the prescription of mineral water was probably adequate. Now, of course, this cannot be treated. Mineral water has also historically been used primarily as a solution of magnesium salts, that is, as a laxative. But modern laxatives, although based on the same concept, are more effective and should be used if necessary.”

Mineral water with high calcium content may reduce the effect of some medications or cause side effects

Separately, I would like to talk about Borjomi and the role of this mineral water in nephrology - to answer an important question: is it too late to drink Borjomi when your kidneys have failed? And also: will Borjomi help people whose kidneys have not yet failed, but the process has begun? Could Borjomi be a remedy to prevent any kidney disease? People with chronic kidney failure have severe restrictions on mineral intake. Borjomi is a medicinal table water with a high sodium content, so people with such problems should only drink it very carefully. Moreover, modern medicine does not believe that regular consumption of mineral water, especially with a large amount of sodium, is a prevention of kidney disease. So it’s never too late to drink Borjomi (but not too early), moderate consumption of Borjomi should not be accompanied by value judgments at all.

Mineral water (especially medicinal and medicinal water) can be a good source of calcium and magnesium (it contains more of them than tap water). Arriving with water, they are fine. But keep in mind that mineral water with a high calcium content can weaken the effect of some medications or provoke side effects (for example, thiazide diuretics and... Another thing is that along with calcium and magnesium, mineral water still contains the same sodium. A lot of sodium. Also sodium, which is most dangerous in the compound NaCl, which is salt, which is “white death". An adult should eat no more than 2.3 g of sodium per day (this is approximately 5.75 g of salt). It can enter the body with medicinal mineral water much more, and this is simply harmful if a person has high blood pressure, kidney or heart failure.

As for sparkling water, it is not clear whether there is any threat from it. The main concerns among doctors were related to the health of tooth enamel and osteoporosis (decreased bone density), but it must be said that little research has been carried out. In the first case, the summary is: probably sparkling water, but maybe it’s harmful. In the second, there was no reason to recommend that postmenopausal women (they have a particularly increased risk of developing osteoporosis) drink sparkling water; teenagers simply should not drink too much sweet sparkling water. And the British National Health Service generally encourages anyone who does not like still water to drink water with. In people with gastroesophageal reflux disease (often manifested by heartburn), sparkling water sometimes causes a flare-up. It is better for such patients. As do people with and frequent.

Detox water and melt water

And, closing the topic of water, let’s talk about water with unique properties, beneficial energy and healing powers, as they inexplicably write in the gloss. If you don't know what detox water is, then congratulations. But in general, this is water into which lemons, cucumbers, mint and anything else “organic, rich in vitamins and antioxidants” are placed, cooled and drunk, thinking that all these plants have given useful substances to the water and now the water, with their help, flushes out toxins from the body (and this is with zero calories). That is, it is assumed that the lemon, simply being in cold water, without any special physical impact, gave up “only what is useful”, and this “useful” went to fight with toxins (which ones exactly are not specified). This cannot be said to be valid and logical statements. It should be noted that the main popularizers of this method of healing are not doctors, but, for example, one of the Kardashian sisters and her.

A healthy diet can include 400 mg of caffeine per day (that's about 3-5 cups of coffee)

The fascination with melt water also falls into the same amazing category. It is believed that if water is frozen and then thawed, it acquires new magical properties. Fans of melt water emphasize the peculiarities of its molecular structure and the fact that there is no “harmful deuterium” in melt water. Deuterium is “heavy” water; in the hydrogen nucleus of this water there is a neutron, which makes the molecule heavier. Molecules of “heavy” water are also present in small quantities () in “light” water. But you can’t get rid of deuterium by freezing/thawing: this requires much more complex ones.

As for the special structure of water after melting, science knows nothing about the possibility of structuring water at its own discretion, although the question is.

There are still a huge number of types of water with amazing properties that have not been confirmed by science, but at the time of writing this book, detox water and melt water have become fashionable.

Coffee

Coffee has long had a bad reputation. And although research results regularly turned out to be either for him or against him, caution always won. But now - attention! shock! sensation! - the study of an unrealistic body of work on the effects of coffee on the body led to the fact that the advantages officially outweighed and coffee ceased to be a “bad guy”. The 2015–2020 Dietary Guidelines for Americans states that a healthy diet can include 400 mg of caffeine per day (that's about 3-5 cups of coffee). It used to be that coffee was a terrible diuretic. A recent meta-analysis found that caffeine consumption increases urine volume, and such drinks can even be consumed by athletes during training. And to finally clear the reputation of coffee: no special recommendations for drinking coffee by people with arterial hypertension. It raises blood pressure slightly (by 10 mm Hg), not for long, and only in those people who rarely drink coffee.

Tea

Tea is probably the least controversial of all the liquids that a person can pour into himself every day. There are many studies that claim that tea protects against Alzheimer's disease, helps fight cancer and promotes weight loss. But none of these or any other similar ideas have a serious scientific basis - the studies from which such conclusions are drawn are not of sufficient quality to recommend that everyone drink several cups of tea a day.

When it comes to tea, you need to be careful when a person drinks herbal teas every day. First, their health effects are poorly understood. Secondly, the quality and safety of herbal remedies is much less controlled than the quality of drugs. Thirdly, herbs may well interact with the medications you take and cause unpleasant reactions. Therefore, if you really like some herbal tea, read about it at least on the website of the American National Center for Complementary and Integrative Medicine - nccih.nih.gov and check its compatibility with the medications you are taking.

Juice, fruit drink and smoothies

Juice, fruit drink and smoothies - it would seem that it could be healthier. But no. Those juices and fruit drinks that are sold in packages often have added sugar, which is not very healthy if a person wants to consume a decent amount of carbohydrates per day. Smoothies and freshly squeezed juices can also have excess sugar - even not added: one glass of freshly squeezed orange juice will take at least 3-4 citrus fruits. Could you eat that much at a time over and over again? Very doubtful. But if you choose between smoothies and juices, then, of course, smoothies are better: at least they contain fiber, which should be included in a healthy diet.

Now, attention, grapefruit juice lovers. This is one of the most hated juices by doctors. It changes the effect of statins, nifedipine, amiodarone, cyclosporine and many others. If you drink grapefruit juice and take any medications, check to see if you are harming yourself.

Milk and yoghurts

If you don't have lactose intolerance Not all lactose intolerant people know this. To find out if you have this disorder, drink a glass of milk. If your stomach hurts, gases begin to form actively, or diarrhea begins, you most likely have lactose intolerance. Lactose intolerance: Clinical manifestations, diagnosis, and management, milk in the diet is. It is high in protein, calcium, vitamin D and potassium. Choosing pasteurized or “live and real”, which lives for a few days, is a matter of taste and risk assessment. Pasteurized milk is definitely something that comes out of a cow and has not had anything special done to it other than pasteurization, i.e. heating. UHT “The word “sterilized” is still preserved in people’s memory. These are also higher temperatures, but the technology is somewhat different, and the taste changed significantly - a boiling taste and caramel from burnt lactose appeared. Then they created modern technology, without these defects. The word “ultra-pasteurization” was coined for ultra-high-temperature processing precisely for the purpose of separating it from the old “sterilization” and getting rid of negative connotations” - from a letter from Maxim Melnikov, deputy director for economics and finance of the Voshchazhnikovo agricultural enterprise, which supplies milk to Danone. , "Umalat" and "Valio".- this is the one that was heated to higher temperatures, but for a shorter period of time. There is no reason to call such milk "unnatural" Unnatural - in the sense that it was not produced by someone else's body.. If manipulations were carried out with this milk that seriously changed the composition, it would be called differently - for example, a dairy product. Temperature treatment is needed to destroy bacteria, and after it the milk can be stored from several days to several months. Exactly how much depends on various factors. The fact is that after processing, bacteria still remain in the milk, albeit in small quantities. They cannot cause any disease in humans, but due to their reproduction, milk can spoil. It is also important that no new bacteria get into the milk (the quality of the equipment and organization of processes is responsible for this) and that there is very good packaging that will not allow the remaining bacteria to multiply and will not allow ultraviolet radiation spoil the taste of milk From a letter from Maxim Melnikov.. Ultra-pasteurized, for example, is packaged under aseptic conditions in complex packaging, thanks to which it can be stored for months. Pasteurized milk can live up to 21 days, but for this, as Maxim Melnikov, Deputy Director for Economics and Finance of the Voshchazhnikovo agricultural enterprise, explains, “high purity of the product must be ensured throughout the entire chain: very good milk (“low bacterial contamination”, “low somatics”), good transportation (high-quality milk tankers, properly washed), good processing equipment, good (“aseptic”) packaging equipment, good packaging, cold logistics to the store, cold shelf in the store.”

If you are healthy, then there is no evidence that you need “live yogurt”

There is milk that doesn't last long but, according to some people, has a better taste. It is usually pasteurized, but its shelf life is no more than five days. For some reason, such milk is usually called “natural” and contrasted with that which can be stored for months. But in reality, this is just milk that has been pasteurized using inferior equipment and bottled in simpler and cheaper packaging. Short-lived milk can also be “raw,” that is, not thermally processed. By technical regulations Technical Regulations of the Customs Union “On the safety of milk and dairy products” (TR CU 033/2013) its manufacturer/seller is obliged to warn the buyer that milk must be boiled before use: a cow you are unfamiliar with may be a source of E. coli, salmonella and much more.

The main question regarding liquid yoghurts is with or without probiotics? And here you need to understand very well why you may need probiotics. If you are healthy, then there is no evidence that “live yogurt” is. Probiotics (and not all of them - yes, they are different) have shown effectiveness only in certain diseases. At the same time, after transportation and then waiting for the buyer, the yogurt may no longer contain at least some decent . And we must, of course, remember that yogurt is far from the best form of delivering probiotics: capsules, which dissolve only in the intestines and do not allow bacteria to pass through the horror of hydrochloric acid, are clearly more reliable.

Cola and other sweet drinks

Despite the fact that these are “all chemicals,” the biggest evil in them is not the ingredients with unpronounceable names, but carbohydrates. Carbohydrates themselves are good and healthy. But not in excess. And it’s better that they come in the company of useful substances like vitamins or minerals. Otherwise, it will turn out that you consumed calories, but everything else necessary for the normal functioning of the body did not, and food with these very vitamins and minerals in the required quantity no longer fits.

Alcohol

Considering alcohol as the main source of fluid is risky. But still, doctors approve of periodic moderate consumption because of the risk of developing cardiovascular disease (although this cannot be said to be recommended: if you don’t drink, you don’t need to start, they say). When drinking alcohol, there are two things to keep in mind: the amount of calories and the amount of alcohol. It must be said that the norm of alcohol consumption in different countries is How much to drink? Eight glasses a day? According to this logic, both a 100-kilogram Egyptian resident who worked in a rocking chair and a miniature Swede who lay on the sofa all day should drink two liters of water. Of course, the mandatory 8 glasses of clean water a day is not true and has nothing to do with a healthy lifestyle. The body is quite happy with any other form of fluid intake - even meat and pizza (yes, there is some liquid there). In favor of plain water, specialists from the American Mayo Clinic cite only “<она>no calories, inexpensive and easily accessible.” If you are hoping to detect the famous “hidden dehydration” by counting what you eat and drink, then you are in vain: you will learn about a lack of fluid from your body (we call this signal thirst), the alert system works well for almost everyone. Problems may only arise in older people: with age, the mechanism of thirst worsens. So you will know about your dehydration, and there can be no “hidden dehydration”.

The next time you brush your teeth, try asking yourself about each action: “Why am I doing this?” My answers six months ago looked like this:

Why do I use this particular toothbrush?

Well, it's simple and beautiful. And the bells and whistles that other brushes have are probably pure marketing, they are of no use.

Why this toothpaste?

She smells nice.

Why do I brush my teeth this way?

I'm used to it since childhood.

Why don’t I have interdental brushes, irrigators and other devices for cleaning my teeth?

Hm. Because life is too short for me to waste it on interdental brushes? I don't know, I didn't think about it.

Sometimes the opposite happens. We are afraid of something that is completely harmless (or almost harmless): scale, a microwave oven, or a monitor that supposedly kills our eyesight.

Every day we do hundreds of stupid things - in the kitchen, in the bathroom, in the bedroom and at the desk. For some reason, we forcefully rub ourselves with a washcloth, buy orthopedic mattresses and are afraid of going blind from constantly working at the computer. From this book you will learn how to live according to science and not die prematurely. Debunking myths on every page! - We don’t need antibacterial soap - But we need to choose toothpaste wisely, otherwise we’ll have to treat our teeth later - Because of improper hand washing, we get ARVI more often - Water filters can harm us - The toilet seat is cleaner than it seems, but the carpet is not very - It’s a terrible pity, but kissing pets is still not worth it. Medical journalist Daria Sargsyan tried to understand our everyday behavior from the point of view of evidence-based medicine: what is good for us, what is absolutely not, and what makes no sense at all. “Why is this and not otherwise?” is her favorite question. This is the third, expanded and corrected, edition of the book. Science does not stand still, scientists continue their research and publish new articles, so Daria re-checked all the facts, refreshed scientific information and rewrote the chapter “About Air”. Let this book become your desk book, and also be studied in life safety classes, distributed in medical institutions, passed from hand to hand and help you live. About the author Daria Sargsyan is a medical journalist, popularizer of evidence-based medicine, editor of the Meduza publication and co-founder of the multi-thousand telegram channel “Namochi Mantu”. Reviews The book is worth reading not so much as an instruction on whether tap water is dangerous and whether it is possible to do without a filter; Is scale in a kettle dangerous? Is it harmful to drink five cups of coffee a day (spoiler: it’s not harmful) - how much as a therapy for urban fears: it turns out that so many of the things that we are so hysterically afraid of are actually not at all scary. In general, read Sargsyan more and listen to the Internet less. Lisa Birger, literary critic Drawing on hundreds of studies, Dasha explains how to wash your hands, brush your teeth, protect yourself from STDs, how to eat, drink and sleep. The book really describes the ideal (as the current development of science understands it) to which we must strive in order to reduce the risks of health problems. I would be glad if this book was rewritten and reprinted every few years in accordance with the latest data. Fedor Katasonov, pediatrician, author of the popular telegram channel "Fediatrics" 3rd edition, corrected and expanded.

Every day we do hundreds of stupid things - in the kitchen, in the bathroom, in the bedroom and at the desk. For some reason, we effortlessly rub ourselves with a washcloth, buy orthopedic mattresses and are afraid of going blind from constant work at the computer. From this book you will learn how to live according to science and not die prematurely. Debunking myths on every page!

We don't need antibacterial soap

But you need to choose the paste wisely, otherwise you will have to treat your teeth later

Due to improper hand washing, we are more likely to get ARVI

Water filters can harm us

The toilet seat is cleaner than it looks, but the carpet, not so much

It's a terrible pity, but you still shouldn't kiss pets

Medical journalist Daria Sargsyan tried to understand our everyday behavior from the point of view of evidence-based medicine: what benefits us, what absolutely does not, and what makes no sense at all. “Why is this and not otherwise?” is her favorite question.

Tap
