Why do we sweat?

The body can be considered a constantly working "furnace". The food we consume is the "fuel" that the body "burns". Every day, 2500 calories are used in this process in the body. They are enough to bring 23 liters of water to a boil! What happens to all this heat in the body? If there were no temperature regulators in the body, we would probably feel like steam boilers. But it is known that our body temperature does not rise (unless we are sick), but stays at an average of 37 degrees Celsius.

Sweating is one of the ways to keep our "furnace" at a normal temperature. Our body temperature is regulated by a center in the brain known as the "temperature center". It consists of three parts: control center, heating center and cooling center.

Imagine that the temperature of the blood drops for some reason. Then the heating center is taken to work. At his command, special glands begin to release more chemicals for combustion, muscles and liver - to spend more "fuel", and soon our internal temperature rises. And if the body temperature, on the contrary, rises for some reason? Then the cooling center comes into operation. The process of oxidation, or combustion of fuel, slows down. And then another important thing happens. The pores on the skin expand so that excess heat can escape and sweat evaporates more easily.

As the liquid evaporates, it absorbs heat. For example, we feel cool after taking a bath, as the water that comes into contact with our warm skin quickly evaporates and cools us down. So sweating is part of the body's cooling process.

Sweat is like a shower that irrigates the body from within. The fluid flows out through millions of tiny holes in the skin in the form of tiny droplets. And these tiny droplets can evaporate very quickly and cool the body when needed.

On days of high humidity, we suffer because the water from our skin cannot easily evaporate. So we use fans to disperse the humid air and make it easier for our sweat to evaporate.

Random interesting fact from the Great Encyclopedia:

Where are the highest and where are the lowest places on the territory of the former USSR?

The highest point in Russia is the Elbrus peak, 5560 meters high, north of the Main Caucasian Range. On the territory of the USSR, the peak of Communism in Tajikistan (7495 meters) rose the highest, and the lowest point was the Karagie depression in Kazakhstan (134 meters below sea level) to the east of the Caspian Sea. The highest point in Ukraine is Mount Hoverla in the Carpathians (2061 meters), the lowest point is the Arabat Spit at sea level. In Russia, the shore of the Caspian Sea is located below all, which is 26 meters below the level of the world ocean.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Wheat breeding has led to a decrease in its resistance 02.01.2019

Food security is largely determined by the yield of major crops. Climate change leads to changes in the weather, and, as a result, the variability of the harvest and food prices, and hence their availability. Uncertainty that food will be affordable causes waves of migration and political instability. To date, breeding methods can ensure a sufficient level of wheat yield in the current climatic conditions, but the climate is changing and many popular varieties may become underproductive.

Helena Kahiluoto of the Lappeenranta University of Technology and colleagues from other European universities analyzed wheat yield data from nine countries - Finland, Denmark, Germany, Belgium, the Czech Republic, France, Slovakia, Italy and Spain. The full data set consisted of almost 11 thousand numbers - the amount of wheat harvested per hectare, to which data on temperature, humidity, time and other parameters were compared. The scientists used data from 991 varieties of winter, spring and durum wheat grown between 1991 and 2014 in 636 locations in nine countries, as well as weather data from their growing areas in eight countries. At the first stage of the study, scientists chose climate change factors that have the greatest impact on crops (humidity, minimum temperatures at different times of the year, temperature changes). They then quantified the impact of climatic factors on crop yields.

The reason for the poor adaptation of plants to climate change, according to scientists, is a decrease in genetic diversity. Selection in favor of a few desired characteristics of the culture impoverishes the gene pool due to the disappearance of screened alleles. The genetic diversity of wheat began to decline after the 1990s. Researchers attribute this decline to an increase in the number of small-scale wheat producers. Increasing competition forced us to shorten the production cycle without wasting time on technological improvements.
