There are three varieties hot water treatment: Finnish sauna (temperature of 70-110 degrees Celsius, humidity 10-15%), Turkish bath (the temperature no higher than 50 degrees Celsius and humidity near 100 percent) and steam room (60-70 degrees Celsius with a humidity of 90%).It turns out, coming to the bath, we are exposed to temperatures that are theoretically supposed to make our blood curdle. Her normal temperature is 32 to 38 degrees is a more accurate value depends on the individual characteristics of the organism and the place where the blood is. For example, in the capillaries on the skin surface it is colder, but in the internal organs the hot. In the armpit of its value in a healthy person is equal to 36.6 degrees. When the temperature begins the process of blood clotting, irreversibly changes its structure. Simply put, it is cooked when the thermometer shows more than 42-43 degrees.

Heats up in the bath our body through the skin facing the «hot» molecules. In fact, temperature is an analogue of kinetic energy; meaning that we invest in the concept of «hot» or «cold» implies a more or less rapid movement of the molecules.

The correlation between temperature and the kinetic energy is easy to understand if you look at steam and ice. In the first case can be seen active movement (of course, not of individual molecules, and their combination), and second, it seems to us that the frozen water is immobile. Actually it’s not, but our eye does not catch such a small movement.

There is a simple formula for conversion of temperature into energy.

To the left is the kinetic energy, which is a measure of the movement of all physical bodies. k is the Boltzmann’s constant and T is the temperature directly in Kelvin. To put it in Celsius, enough to take away 273. From the school course we remember another formula that you can calculate kinetic energy.

From this we can deduce a formula to calculate the speed of the water molecules depending on temperature.

The mass of the water molecules is approximately 3×10⁻2⁶ pounds. These data are enough to calculate the speed of water molecules in each type of bath. Get in the Turkish Hamam molecules «run» at a speed of 667 meters per second, in the Russian bath 689 meters per second, and in the Finnish sauna 717 meters per second. It seems that the difference is small, but our skin cells is kept very small range of speeds of molecules, in particular water. And if you go beyond it, the skin starts to break, because the molecules that make up the surface of cells that take over part of the energy of each water molecule, with which the «touch». They also begin to move faster and more aggressively — so we get burns.

Planinata the artist imagines the molecules of water in the process partytake way, a larger number of water molecules leads to faster heating of the body. Of course, the air is not only water vapor, it still contains nitrogen, oxygen, carbon dioxide, argon, helium, krypton. But these substances are volatile gases and practically does not remain on the skin, so I can’t give her your energy. Now I understand why in a hot Finnish sauna is so dry and in the wet Turkish bath, the temperature is low.

Sweat at 98-99% consists of water molecules, and one to two percent fall on the organic and mineral substances. On the surface of the body it is excreted with the sweat glands. Water molecules are moving, going at the same time in drops on the skin. This is due to the relations between the molecules. While in drop, they move erratically — some faster, others more slowly, sometimes crashing into each other. And the more heat, the faster they are worn. This system-drop can be compared with the peacefully grazing herd — older horses is that from time to time take a step to search for a new feed, the more young people communicate and lightly play with each other, but frisky foals are so full of energy that sometimes run away from the herd. And most fast (hot) molecules «break free» from the accumulation of their own kind, thus reducing the total kinetic energy. And if you remember the above formula is logical that falls the temperature drops.

And in the humid air sweat can not evaporate fast enough, it prevents a strong flow of «hot» molecules from the saturated air water. This is our heat tolerance — seasoned travelers know that the same temperature is easier to endure in the wilderness (in the shadow, of course) than in the rainforest.
