The question is, go to the ocean, there are winds, the sea is cooler and the weather is colder. I think also Croatia, Montenegro, but at the expense of a lot of vegetation.
We, too, at one time thought that the heat is easily tolerated in Montenegro. But we arrived at the end of July +38: 001 :. And the vegetation there ... not so much ... Well, depending on where, of course ... The road to the beach (St. Stephen) is an open scorching sun. For an amateur.

In Tunisia on the island of Djerba
24.05.2010, 23:54
I would definitely not advise Djerba - we were in April, as if not in season, and it was hot.
Islands are the safest choice. It's good in Tenerife, but we were in April-May, not hot, a breeze, but swimming is frankly cool. Corfu (Zakynthos, probably the same situation), although it blows from all sides, but even at the end of June is clearly more than 25, although the water 22 is just a miracle. But you can sit out in the shade? If the hotel - we do not have a beach, but a large shady area in the trees - could easily be in the shade all day long.
Maybe Portugal, Madeira?

The question is in the climate in general, and not in the number of degrees - in the southern sea in July-August it is hot everywhere, but in a dry climate the heat is transferred much easier than in a humid one. by the way, even in Turkey, in the Mediterranean Sea, the level of humidity varies greatly, depending on the place - in the Maramaris region, for example, the air is much drier than in the Kemer region. We rested in the summer and there. and there are two big differences. In August, we rested in the village. Sarigerme, near Dalaman - it was hot, but dry, and in the evening it was normal in the room - we didn't even turn on the air conditioner. I highly recommend - Iberotel Sarigerme Park. Only the prices are there - uuuh.

Where have you been in Turkey? Where the humidity is high?
In St. Petersburg, the air humidity is usually also high.
This I mean that you can not stand the strong sun or heat in a humid climate? The drier the air, the easier it is to tolerate high temperatures. And in Central Russia, where there is usually no such humidity as in St. Petersburg, how do you feel at 25 degrees?
In Tenerife, as far as I know, the sun is very active in summer, but the air is dry and easy to breathe.
In Turkey, I was in Alanya in the summer - I was dying from the heat even late in the evening (I don't remember the temperature), in the second half of May I was in Turkey in the Kemer region near the mountains - at temperatures above 28 degrees it was hard especially on the sun, in other countries (Italy, Spain, Bulgaria) was BEFORE giving birth and endured the heat differently than now, because after the birth of a child, for several years now I can not stand the stuffiness and heat, I can not go to the bathhouse and sauna - it is very difficult ...

In Turkey, I was in Alanya in the summer - I was dying from the heat even late in the evening (I don't remember the temperature)
We were in Alanya in July, +42 degrees: 001: nothing remained alive! The 1.5-year-old son endured everything gorgeous, and the adults were helped by cold wine and beer :))
True, in the afternoon we had a quiet hour, somewhere from 13-15.30, the men were asleep, and I went shopping :), I love this business both in the heat and in the cold: 008:
25.05.2010, 16:52
I can hardly stand the heat, in St. Petersburg at more than 25 I hide in the shade
In Turkey, after 11 days at 28-30 degrees (and this is in May) I could no longer be in the sun
I really want to go back to the sea or ocean in the summer ... where to go so that it is not so hard to endure the heat?
Are the islands of Greece suitable? Zakynthos for example? or Tenerife?
where, please advise!: 091 :: 091 :: 091:
I, too, do not stand the heat well. I go on vacation in September to the Crimea or to our coast. The sea is warm, and the weather is already not hot.

Correctly said, apparently I can not stand the heat in a humid climate: ded:
In general, I don’t even know where to go in the summer to breathe easily
Before Turkey, you seem to have also traveled to countries with drier climates.
It seems to me that it is a combination of heat and high humidity.
See dry climate. If Turkey, then only the coast of the Aegean Sea. Greece, primarily the islands, also Halkidiki. Crete, Rhodes - fresh wind, but also very active sun. Corfu, Zakynthos - colder, I don't know by the wind. Halkidiki - there is no particular wind, but there is no stuffiness either, this is Northern Greece, there is a lot of greenery and a mild climate.
I myself can hardly stand high humidity at high temperatures. At the same time, in Halkidiki, at 33 Celsius, it was quite good for me by the sea, not by the sea - it was hot, but tolerable.
Tenerife has an active sun, but dry air, a very healthy climate.
Tunisia, I think, will do too. Hot but not humid.

In September and October, I know where to go, but the question is where IN SUMMER (June, July, August): ded:

Egypt, there is definitely no heat (and this is in August) compared to Turkey, Cyprus and the Mediterranean in general, Red with a bang!

I was not in Egypt in August, but I would not have dared :) There, of course, the air is dry and there will definitely not be a steam room, but still the sun is something else ...
By the way, I was in mid-June - early July in Cyprus, Ay-Napa and Larnaca. At this time, there is still no high humidity and it breathes well. At the end of July and in August, according to the locals, it is simply tough. Hot, humid and stuffy.
IMHO, August is generally not the best month in terms of rest. Hot, expensive and a lot of people. Europeans have vacations.
We are considering June and July.
25.05.2010, 20:16
We are considering June and July.
I will go to compare the air and water temperatures in Tenerife, Cyprus, Zakynthos and Chaldiniki.
From personal experience, I can say that all these figures do not really give a picture, especially with regard to the temperature of the water. Better to read the reviews.
Tenerife has an ocean, where the water will be the coldest on the list. In Halkidiki (on the inner side of the "fingers") and in Cyprus, the water is warm from mid-June. True, a lot here depends on the weather in spring.
Moreover, although theoretically in Cyprus it should be hotter and the water warmer than in Halkidiki, in practice the water on the beaches of Kassandra and Sithonia seemed to me even warmer than in Ay-Napa in Cyprus. And the warmest water was in Larnaca - generally fresh milk. I compare Ay-Napa and Larnaca on the same trip and even swimming there and there on the same day :)
The air temperature in Cyprus after the 15th of June and until the beginning of July is on average slightly higher than in Halkidiki, but the sun itself in Cyprus is much more active.
It’s not very good to go to Cyprus in July. The degree is increasing, the humidity is also increasing. At the beginning of the month, we felt good there. My friend went to Limassol before me, either in mid-July, or at the end. She said the humidity was high. I myself was preparing to get into the steam room, but nothing happened.
In July it is better to go to Greece.
Earlier, when we just set out on our way to a new life, we endured with a bang the humid tropical climate of Asian countries. This is not only about Thailand, but also about Vietnam, Sri Lanka, Laos and other countries of Southeast Asia.
How we live in hot climates
All my life I loved hot weather, because I was born in Siberia, where in summer the air temperature is usually stable at + 28C + 32C. Having moved to live in Moscow, I did not perceive the Moscow summer in any way and believed that 18-23 degrees is a spring climate, not a summer one.
If the temperature of the skin is higher than the average radiant temperature, the body gives off heat from the radiation to the environment; if it is the other way around, the body receives heat from the environment. Of course, more than once you have noticed that on hot days there is more humidity in the lower atmosphere - this is sweat and the feeling of warmth is higher. Therefore, if the relative humidity is lower, the more sweat evaporates from our skin, and we will feel fresher. However, when the temperature is low, the feeling of coldness also increases if the relative humidity is very high.
As with everything, there is virtue in the middle. Thus, extreme moisture protection is not suitable for health, and humidity values below 20% can cause, for example, respiratory tract infections. On the other hand, humidity above 80% is also not recommended, as mites, fungi and bacteria multiply under these conditions.
Slava, in turn, also turned out to be a thermophilic person and more perceived the heat as a good time for the mood to rise and the soul sang. Well, it's much more pleasant to walk in colored shirts and summer shorts, and not wear 5 pants, wrapped in warm clothes.
All these years of travel, starting from Sri Lanka, we have never stopped loving the heat. Not warm, namely heat +32 +34 degrees.
Air movement also affects the heat sensation. A higher speed causes an unpleasant effect that is difficult to withstand, the more the air temperature is lower. The type of clothing we wear also affects our sense of thermal comfort. We must take into account that the greater the thermal resistance of clothing, the more difficult it is for the body to break away from the generated heat and transfer it to the environment. Thermal comfort is achieved when there is a certain balance between the heat generated by the body, as a result of the need for energy and that which is able to give or receive from the environment.
And even when we lived in Krabi in March, when the hottest season in Thailand is in full swing, not without effort and groaning, it is true, but we could withstand walking from the beach and back, defrosted at + 36C. I remember we were chilled by the realization that when we got to the condo, we would plunge into a cool pool.
That feeling when I got to my pool in 40-degree heat. Photo.
How to get the comfort of your home
We have already seen that there are a number of factors that affect the feeling of thermal comfort, however the fact is that houses two mainly come into play: humidity and temperature. In this case, there is no need to resort to air conditioning or heating, as the thermal sensation should be comfortable. A suitable air conditioning system should create a comfortable indoor climate for most of the occupants in the room, so that the air can be heated in cold weather and cooled in warm weather.
I can't stand the heat in Laos
Only in Laos, whenever we came for a Thai visa, it was very stressful to endure the heat. You walk down the street at your limit. And on the day before last, I managed only halfway from the hotel to the embassy, and we had to go by tuk-tuk. Since 34-36 degrees is still tolerable, but +38 is already something! Even for an organism trained by a hot climate.
With so many healthy eating theories available, it's hard to know which one is most relevant. A Chinese tradition built over thousands of years offers a different approach to today's diets. Sometimes it's hard to figure out what's good for the body, with numerous diets preaching all sorts of theories, for the best way to feed yourself. Thus, the perception of what kind of healthy food really changes at all times. Even if we know all about fat, carbohydrates, proteins, minerals and vitamins, there is always new research that introduces something new and makes previous beliefs obsolete.
It is advisable to go outside in Vientiane closer to sunset. Pictured, Mekong River
Everything is changing
I don’t know how, in just 11 months outside Asia, we lost the habit of tolerating heat easily and naturally. There are thoughts that age affects. I thought that such thoughts would come to me after 40, not after 27. But so far age is the only intelligible explanation.
But what do our bodies need? Using the concepts of traditional medicine, the Chinese have their own approach to healthy eating. This is probably the culture that believes most in the principle of "you are what you eat" - even if they don't always follow this letter. Below we take a look at what concerns food and medicine, and whether these concepts can be applied outside of China.
Compared to Western culture, food and medicine overlap in Chinese culture. For example, watermelon is a food, but it can also have a healing effect on hot days due to its high hydration capacity. Ancient clans of China, from about 200 BC. Some foods have cured disease, others have cured death.
Now I know that the most optimal air temperature for me should be +25 +28, taking into account life in Asia.
Here, literally every degree counts. If in Russia you do not feel much difference between +25 and +27, then in Asia the temperature should rise by one or two degrees, the body immediately gives signals.
Now we try not to go in extreme heat to some sights that need to be reached up the hill. We make rest stops more often. And we hide from the sun on the beach, choosing shade, not sunbathing.
Over time, the philosophy of Chinese medicine has developed. However, there are some foods that the Chinese consider "medicine" rather than "food," as is the case with ginger. However, before using it for treatment, it is necessary to consult a professional, as its ingestion can lead to poor health. The reason for this is that foods have different properties, and each person, one organism, reacts completely differently depending on what enters the body.
In traditional Chinese medicine, foods are categorized into five entities called shiqi: cold, cold, neutral, warm, and warm. The nature of the diet is not determined by its instantaneous temperature, but by the effect that it can have on the body after consumption. Therefore, one of the foundations of Chinese medicine is the preservation of a "neutral" organism.
And just for the sake of a photo, you can climb onto slippery stones and pretend that it’s great for you to lie under the scorching sun. True, it was lucky here, the photo was taken in not hot weather on
I buy new things for sun protection
Recently I got a panama hat, because the hats are uncomfortable, they are blown away, and somehow I am not comfortable in the cap. But a panama hat is a protection for the head and hair from the scorching sun. But the body cannot be protected in any way.
Warm, warm foods generate heat in the human body - such as beef, coffee, ginger, peppers, and roasts - while cold and cold body temperatures are lower, such as salads, cheese, green tea, and beer. Foods such as oil, rice, pork, and most fish are considered neutral.
A person who has swallowed a lot of hot foods usually feels hot, he or she is in a bad mood all the time, with a swollen tongue, and may be constipated. Those who eat a lot of cold or frozen ingredients have cold feet and hands and may feel weak or have circulatory problems. When this happens, it is recommended that you stop eating one of these foods.
I never thought and almost always laughed at the wrapped up Asians, but while updating my wardrobe, I bought blouses with long sleeves and made of denser material to keep the body temperature, and not let it heat up, as it would be in a regular T-shirt. Of course, I don't always wear them, but I gradually introduce such things into my wardrobe. (cm.)
Like the Western world, the Chinese categorize aromas in five: acidic, bitter, sweet, spicy, and salty. But for them more sensations. In traditional Chinese medicine, every bite in food carries nutrients to the appropriate organs: acid goes to the liver and helps stop sweating and coughing; salt enters the kidneys and can drain, cleanse and soften food masses; bitter foods go to the heart and small intestine and help cool the body and dry out moisture; pepper enters the lungs and colon and stimulates appetite; sweets go to the stomach and spleen and help lubricate the body.
The only moment that even closed clothing will not help is moisture. Still, dry heat and +35 is tolerated 10 times easier than humid and tropical at +30.
We live in Pattaya, here in the summer there is comfortable weather
In Pattaya this summer, like 2 years ago, the temperature is normal. We are here partly for this reason, as we wanted a more comfortable climate conducive to outdoor walks. In Pattaya in the summer you can walk for 2-3 hours on foot along the promenade along the beaches, breathe the sea air, admire the scenery.
Therefore, it is important that each of these aromas are present in the diet. Does this mean that in order to be healthy, you just need to eat neutral foods in all flavors? Not necessary. Food choices are influenced by body physiology, seasons and where you live, says Chang Kei-fat, a practicing physician in Hong Kong. The condition of the body can also be influenced by age and gender. That is, traditional medicine specialists adapt their recommendations to different conditions.
Just as we all have different personalities, we all have unique constitutions. And just as you cannot communicate with everyone in the same way, you cannot feed all bodies with the same food in the same way. The classifications are going through changes in Chinese medicine.
There are quite a lot of sunny days this year, but there are also enough short-term rains. It rains about once every 2-3 days. There are often cloudy days with a breeze and stretched clouds, which is also nice.
Every time we go for a walk, we buy water. I feel thirsty even in the cool, when the temperature is only + 31C
A person with a lot of "moisture and mucus" in their body tends to be overweight, may sweat a lot, and have an oily face. These people also tend to be softer in nature. However, a person with a lot of "dampness and warmth" is usually irritable and often has an oily face with a lot of acne. Both types need different foods to get rid of moisture. This means that sweets that lubricate the body can make things worse.
Each type of food, depending on its nature, can improve or worsen the situation. "There is no substance that is good for everyone," says Guo Jimin, a Beijing native who owns a store in Cologne, Germany. "Many people say that ginger is healthy, but if you are a person with a dry body and a lot of heat in your body, the more ginger tea you drink, the drier your body will be."
But the humidity remains high. And during this period, even in the evening, whatever one may say, you return home wet and run to the shower. And you are wet, not because you sweated from stuffiness or exertion, but because the humidity ate you up in 10 minutes of being outside.
Questions to readers
All the talk about the heat and the climate to what I want to know from you, can you write some advice on dealing with humidity or tricks on how to keep your body cool for a longer time?
It is also necessary to consider both the season and the time of year. For example, spring is usually wetter in China, which means that this season is best to eat foods that can kill moisture in the body, such as corn, beans, and onions. Summers are hot, so it is best to eat foods that can cool the body, such as watermelon and cucumber. Autumn is dry, which means that this season we need food to lubricate our bodies, such as peas and honey. Winter is cold, so it is best to eat hot foods like beef or shrimp.
In a globalized world, it's easy to find off-season products. However, Chinese traditions suggest that this is not the best way to feed ourselves, as seasonal foods provide us with the nourishment we need in a particular season. A similar concept exists in the Western world.
How do you handle the heat? Do you think that age really gives results such as heat intolerance? Maybe you know cities in Asia where the temperature is no more than 25-28 degrees during the day, at least 2-3 months. Maybe there are such cities in Thailand? Except Chiang Mai.
I would like to note right away that due to the heat and humidity, we are not going to leave Asia and return to Russia yet. You can relax on this score
The weather in one place also affects food choices. For example, Guo cites Sichuan Province, China. "The climate there is very humid and cold, so the people of Sichuan love spicy food because it makes it easier to sweat and thus removes moisture from the body." Guo adds that if people from temperate regions eat too much spicy food, the body temperature also gets too high, which is not very healthy.
But then, what is healthy and what should be avoided? According to traditional Chinese medicine, all food is nutritious, and as long as a healthy person does not overeat one food, nothing is harmful to health. Chinese philosophers always recommend to find the "middle earth", i.e. avoid extremes. According to the traditions of the Asian country, it is also very important not to overeat and consume foods with a moderate temperature, while avoiding overloading the digestive organs.
Now we would be eager to go somewhere on an expedition to or even to Antarctica for temperature diversity
On hot days, a person loses about 3-4 liters of fluid. The summer heat has already been felt by residents of some cities, and many remember the abnormal heat of past years. According to the promises of weather forecasters, this year the summer will be even richer for long hot days. And this means that we will again have to succumb to the stuffiness, in search of a breath of saving coolness. But how to learn to survive in the heat and feel comfortable when the scale on the thermometer goes off scale.
In the end, it's all about balance. There is a Chinese saying, "Five grains provide nutrition." Five vegetables provide replenishment. This means that a balanced diet, in which foods are consumed in appropriate combinations according to their essence and tastes, is able to provide the human body with what it needs.
How Lack of Sleep Affects Your Health Recent research shows that a little sleep has a large effect on a person's overall well-being, regardless of habits such as smoking, drinking or stress. Find out what research is talking about the topic.
Why is it so difficult to endure the heat?
For a person living in a temperate climate, the most optimal temperature conditions in summer are in the range of 18-24 degrees Celsius. If the air temperature exceeds 25 degrees, then the human body feels. And despite the fact that this is considered moderate heat stress, a person in the heat may experience changes in emotional activity, a decrease in attention and performance, and increased drowsiness.
What is the optimal home temperature? There is no clear answer to this question. Another is the warm tolerance of our body in summer and winter. During the summer months, when the windows are hot, our bodies become accustomed to higher temperatures. Reverse - winter, when the body tolerates the cold better.
The answer to this question also depends on the type of room. The temperature in the bedrooms should be lower than in the living room, because sleeping in a room that is too warm does not provide enough rest. As in the bedroom, also in the kitchen, the amount of heat supplied can be reduced, as it is additionally heated during cooking.
If the air temperature approaches +30 degrees and above, then there is a risk of overheating of the body. At the same time, in such heat, first of all, the cardiovascular system suffers: blood pressure rises - this is how the vessels react to overheating when the body tries to adapt the thermoregulation system by expanding the vessels so that they give off more heat.
Fact! "Dry" heat is more easily tolerated, while "wet" heat puts additional stress on the body. Indeed, in conditions of high humidity, heat exchange is more difficult, it is more difficult for a person to sweat, an additional load on the cardiac systems appears.
The heart rate and respiration rate also increases - these are compensatory mechanisms that are designed to enhance heat exchange. In fact, the body reacts to heat in the same way it does to exercise. Moreover: in the heat, the kidneys and joints suffer (due to dehydration, salts begin to crystallize in the kidneys, on the surface of the joints), nodes form in the thyroid gland, and the risk of thrombus formation increases due to thickening of the blood.
How to endure hot days easier?
Heat is less tolerated in cities than in villages or outdoors. After all, additional heat rises from the hot asphalt, harmful substances evaporate. Therefore, if possible, try to hide from the heat in a park or forest. And if you react to the summer heat with a deterioration in well-being, you need to help the body survive it.
Since a large amount of fluid is lost on hot days, its deficiency needs to be replenished. But not with sweet water, kvass or beer, as we used to do, but with ordinary drinking water. Water should be drunk often, but little by little, in order to constantly maintain its balance in the body. At air temperatures above +30 degrees, you must drink at least half a liter of water per hour - about a glass every 20 minutes.
Since potassium and sodium are washed out of the body in the heat, you should drink slightly salted water - it normalizes the balance, reduces evaporation and retains fluid in the body. It is enough to put two or three grains of salt in a glass. You can also acidify the water - add a few drops of lemon juice or toss in a piece of lemon, or add a little citric acid.
Remember a few simple rules to help you survive in the heat:
- Replenish your fluid deficit by drinking a glass of regular still water every 20 minutes.
- Don't go outside without a hat.
- Be sure to protect your eyes with sunglasses.
- Get out of town or out into the countryside more often.
- Eat less sugary, salty and spicy foods, and don't overload your stomach.
- Eat fresh fruits and vegetables to support immunity and reduce intoxication.
- Avoid spirits, coffee, tea, or other caffeinated beverages to avoid running to the toilet more often than usual and thus further increasing dehydration.
- It is good to drink whey in the heat - it saturates the body with trace elements that are excreted from the body along with sweat.
- Drink also compotes, fruit drinks, compotes. They saturate the body with vitamins, trace elements, antioxidants and normalize the acid-base balance in the body.
- Mint tea will help a lot in the heat, since menthol has a slight cooling effect.
- And you can also cheer up if you moisten the back of your head, neck, armpits or popliteal folds with water or wet wipes - in a word, areas where blood vessels are close to the skin. It will cool and refresh you!
Who is it dangerous to be in the sun?
Being under the sun, in general, is harmful to everyone, since ultraviolet, like radiation, has the ability to accumulate in the human body and manifest itself later - the skin will age faster, tumors, cancer may occur, and internal organs of a person may hurt. Ultraviolet radiation also works in the shade, reflecting off asphalt, water or windows. Therefore, everyone, without exception, needs to be protected from the sun's rays.
However, there are population groups for whom the heat is deadly: hypertensive patients, elderly people, children. People who have many moles on their bodies are also at risk. Indeed, under the influence of ultraviolet light, a mole can develop into a malignant tumor. It is dangerous to be in the sun and for those who have chronic diseases and fair skin - they are more likely to get burned.
From 10 to 16 o'clock, ultraviolet rays are especially aggressive, therefore, at this time, being in the sun is strictly prohibited for all categories of the population. The solar radiation that a person receives while walking down the street is quite enough to provide the body with the necessary amount of vitamin D.
On hot days, a person loses about 3-4 liters of fluid. The summer heat has already been felt by residents of some cities, and many remember the abnormal heat of past years.

It is dangerous to be in the sun and for those who have chronic diseases and fair skin - they are more likely to get burned.
Children under two years old are strictly prohibited from being in the sun, because children's skin is two to three times thinner than that of adults.
From 10 to 16 o'clock, ultraviolet rays are especially aggressive, therefore, at this time, being in the sun is strictly prohibited for all categories of the population. The solar radiation that a person receives while walking down the street is quite enough to provide the body with the necessary amount of vitamin D.
The weather conditions that have been established in recent days in most of the European territory of Russia have caused abnormal heat and heat. One after another, there are weather reports, which report that another temperature record has been broken in this or that city, which had lasted tens, or even a hundred years, before that. However, until a certain time, the heat does not give us much discomfort. Even at high air temperatures, you can feel quite well. At what point does the hot weather become unbearably stuffy, and the heat begins to squeeze life out of us? Why in the equatorial regions of the Earth the air temperature of +20 ° C or even less seems oppressive, and in the subtropical and tropical deserts of North Africa, Arabia and Mexico, the temperature of the order of +35 ... + 45 ° C is not yet accompanied by a feeling of stuffiness?

The thing is that the feeling of stuffiness depends on a combination of various meteorological characteristics: atmospheric circulation, air mass, solar radiation, cloudiness, wind speed, air temperature and humidity. In this case, the main reason for the occurrence of stuffiness is a certain combination of indicators of air temperature and relative humidity. Relative humidity is the percentage ratio of the actual amount of water vapor to the maximum possible content in the air at a given temperature. Relative humidity equal to 100% means that the air is saturated with moisture as much as possible and at this temperature it can no longer accept additional amount of water vapor. At 100% humidity, a person may have a feeling of stuffiness even at an air temperature in the shade of +16 ° C. Whereas at a temperature of +26 ° C and a relative humidity of 50%, a person will feel quite comfortable. Thus, the lower the relative humidity of the air, the easier it is to tolerate hot weather. That is why in the arid regions of the Earth, such as the Sahara Desert, the air temperature of about + 40 ° C at very low values of relative humidity (less than 20%) does not cause a feeling of stuffiness. In Europe, for example, at a humidity of 60-80%, this sensation arises already at temperatures of +20 ... + 25 ° C. In equatorial latitudes, where the relative humidity exceeds 80%, the temperature, even about +20 ° C, is poorly tolerated.

In general, thermal comfort arises when such meteorological conditions develop under which the body's thermoregulation experiences the least stress. When comfortable, the average surface temperature of the skin is 31-33 ° C. The physiological response to overheating is to increase the body's release of heat through radiation, convection and evaporation. When radiated, heat is released in the form of electromagnetic waves in the infrared range. When the air temperature rises, infrared (thermal) radiation from the surface of the body decreases, and when the ambient temperature reaches the temperature of the skin, radiation becomes impossible. As for convection, the body's heat transfer occurs through turbulent mixing, that is, the air in contact with the skin heats up, becomes less dense, rises, and colder and heavier air takes its place. In this case, the higher the speed of movement of air flows, the more intense the heat transfer. This is why the wind enhances turbulent heat transfer and reduces the feeling of discomfort and stuffiness. For convection to occur, it is required that the surface of the body flows around air with a lower temperature than the skin itself.

As soon as the air temperature exceeds 31-33 ° C, evaporation remains the only way to transfer heat. At elevated temperatures, the overheating of the body is compensated for by increased sweating, and the heat spent on evaporating sweat, as a result of which the body cools. However, in conditions of high humidity and calm weather, sweat does not have time to evaporate from the surface of the skin and begins to “pour out like hail” even at a relatively low air temperature. It is this state of the organism that is characteristic of the phenomenon of stuffiness.

An interesting fact is that the inhabitants of the tropics have significantly more sweat glands than the inhabitants of temperate latitudes. This makes it easier for Africans to tolerate the hot and humid climate of equatorial Africa than visiting Europeans, who need months, and sometimes years, to fully acclimatize. After all, a person cannot change the weather conditions! Some consolation is the fact that with the help of ventilation systems, air conditioners and dehumidifiers, you can make your stay in the room more comfortable. True, here you should know when to stop, because too dry air negatively affects your well-being.
The fact is that in hot weather a person sweats intensely (the body strives for thermoregulation). In dry air, sweat evaporates quickly, which leads to a decrease in body temperature. In humid air, sweat does not evaporate so quickly. And since excess energy is not drained from the body, the body overheats. In addition, it is more difficult to breathe in humid air, the air is filled with a large number of infectious agents, and there is a “steam room” effect.
A bit of physics
Let's go consistently. Evaporation is a process when the molecules of a body (in this case, water) acquire a speed sufficient to detach from the mass. We can say that molecules leave (evaporate) with the greatest speed (energy).
This means that they take with them part of the body's energy and the body cools down a little. You've probably noticed that after getting out of the water, it gets cooler the higher the air temperature. This happens because evaporation is faster, and the evaporated molecules carry away body heat. That is, the higher the ambient temperature, the more intense the evaporation, the more the body cools, from the surface of which evaporation takes place.
But the intensity of evaporation also depends on the humidity of the air. At a certain humidity, the number of evaporated and condensed molecules (that is, returning to the surface of the body, bringing energy with them) becomes the same, the system is in dynamic equilibrium and the body gives off almost no heat. With a decrease in the humidity of the environment, the number of evaporated molecules begins to exceed the number of condensed ones, which means that the body cools down faster. And the lower the humidity of the environment, the more intense the evaporation and the greater the proportion of evaporated molecules, and, therefore, the more intensively the body is cooled.
How to survive the heat without harm to your health?
Rule # 1: In hot and hot weather, try to stay in as little direct sunlight as possible
And also in rooms where there is no regular rapid exchange of air inside, and the air temperature rises above the ambient temperature outside. Many people spend hot times indoors, so it is important that indoor air circulation is constant and regular.
Rule # 2: Maintain Good Air Circulation In The Heat Where You Spend Your Time
To improve air circulation, use hair dryers and fans that can be attached to the ceiling (often chandeliers are sold with fans and such chandeliers are appropriate to have in the summer) or on a tripod in a place where air exchange is not difficult. Try to keep the interior doors open so that air can circulate from one room to the next. Remember that cold air is heavier, so it is always cooler on the lower floors of the house and in the basement than on the upper ones. If you do not use basement rooms, then keep the door to the basement room tightly closed to prevent cool air from leaking out. In the evening, when the heat subsides, open all the windows or at least the vents and try to keep them open until morning. Close the windows when the sun rises, and use blackout curtains and blinds to prevent the building from heating up.
Rule # 3: Build Your Cooling System
In the absence of a portable or central air conditioner, indoor air can be cooled using “household appliances”. For example, place a portable fan running in front of a bowl, saucepan, or box filled with ice cubes. Since the refrigerator in your home works anyway, use a freezer to make ice. If there is no ice, use cold tap water.
Dry heat, when the air humidity is low, is more tolerated than heat when the humidity is high. However, too low humidity leads to dry skin, poor body heat exchange, damage to the upper respiratory tract. Modern air conditioners, especially of centralized type, are equipped with an automatic air humidification system, which allows maintaining the humidity in the room in a comfortable zone. Portable humidifiers can help people who don't have or older air conditioners in their home.
Rule # 4: Don't overload your digestive system with copious amounts of food
Many people complain of poor appetite in hot weather, however, they consume huge amounts of food, including meat and fats. It is important to remember that assimilation of fats and proteins produces more energy, which can lead to the so-called "metabolic shock" in an elevated environment.
It is desirable to give preference to vegetables and fruits, preferably raw. Heat can be a good period of fasting days and losing a few extra pounds. The main thing is that this loss does not turn into a "disease" and does not go beyond healthy weight loss (no more than 3-4% of body weight per month). Try to eat food cold, in small portions, so more often. Acceptance of flour and sweet products should be limited.
Thin people tolerate heat much more easily than overweight people, so take care of a healthy, normal body weight beforehand. The fuller a person is, the less is the ratio of skin surface area to weight, so heat exchange is slowed down and impaired.
Some medications can decrease or increase heat tolerance, so it is important to talk to your doctor about changing medications, changing the dose, or stopping them if this does not harm your overall health or aggravate the treatment of the disease.
Rule # 5: Avoid alcoholic beverages and alcohol in hot weather
It is important to limit the intake of products containing caffeine, as well as those that provoke high urine production (diuretics, both natural and synthetic) and have dehydrating properties. For example, apple cider vinegar and a number of medicinal herbs can lead to rapid dehydration.
Rule # 6: Use the Cooling Properties of Water
In addition to drinking enough water internally, take advantage of the cooling properties of water by taking cool showers. Even a foot bath in cool water can significantly relieve stress and create a feeling of freshness in hot weather. It is enough to pour some cool (but not cold) water into a bowl or basin and hold your feet in it for 5-10 minutes. Use wet towels and sheets to cover your shoulders, back, and entire body in hot weather.
Since the air in the room is often dry in hot weather, use special portable humidifiers. You can also place a bucket or bowl of water in the room, or fill a container bottle with water and sprinkle water periodically to humidify the air in this way.
