The difference between hot springs and hot springs. How to distinguish real and fake hot springs?

Many people like to soak in hot springs in winter, and there are many possibilities for hot spring bathing, such as the types of hot springs and the various curative effects and possibilities of hot spring bathing. What everyone is most concerned about now is which of the two different types of hot springs and hot springs is better and how to distinguish them.

How to distinguish between real and fake hot springs

At present, there are many hot springs, large and small, and there are also many "fake hot springs". Experts say that not just "a mouthful of hot water" has health benefits. my country's "Standards for Classification of Medical Mineral Springs" stipulates that hot springs contain a certain concentration of minerals (more than 1g of soluble solids per liter of water) and special gases (such as carbon dioxide, hydrogen sulfide, radon, etc.). ), and a certain amount of chemical components (such as iron, bromine, fluorine, etc.) can have a medical and health care effect on the human body.

Some "fake hot springs" come from mountain springs or groundwater. The hot spring water boiled from this water source may also be rich in minerals and have certain health effects. Of course, the mineral content and composition of the water must also be analyzed. Some hotels simply boil tap water to use as hot spring water. This kind of fake hot spring has no health care function. It just takes a warm bath, which can at most relieve stress and relieve fatigue.

There are 4 ways to distinguish real hot springs from fake ones:

First, real hot springs have a slight smell of hydrogen sulfide, which is the smell of rotten eggs;

Second, real hot spring water feels greasy on the body;

Third, people can feel obvious buoyancy when soaking in real hot springs;

Fourth, soaking fingers in hot springs The skin will not wrinkle in the water.

What is a hot spring?

Mine water that gushes naturally from the ground or is collected artificially and has a water temperature of 25°C and does not contain minerals (including macroelements and trace elements) that are harmful to human health. . Mineral water below 25 but containing minerals beneficial to the human body is also considered a hot spring.

The pH value of hot spring water

The pH value of hot spring water depends on the ratio and concentration of anions and cations contained in the hot spring water. It can be seen in hot spring water with a pH value of 2 to 9, but Generally speaking, neutral hot springs with a pH value of 6 to 8.5, weakly acidic or weakly alkaline hot springs are less irritating to the human body and are more common.

Hot springs

Hot springs are groundwater outcrops with spring water temperatures above 45°C but below the boiling point of local surface water. Generally divided into two types: submarine hot springs and terrestrial hot springs.

Hydrothermal vents

Deep sea hydrothermal vents are generally distributed in volcanic belts at the edges of plates. In fact, they are a bit like volcanoes themselves. The seawater that seeps into the earth's crust is heated by the lava close to the surface, dissolves and carries many minerals, and gushes out from the hot spring mouth. Typical sulfide hot springs, the minerals in them will form black chimneys at the vents, which can be as high as ten floors, constantly emitting black smoke. There are many crab-like and shell-like creatures on and around the chimney walls, as if everyone is vying to live closer to the black chimney. In 1977, when scientists first discovered hot springs in the deep sea, they saw such a strange sight. If you hadn't seen it with your own eyes, it would be hard to believe that there is such a group of life on the seabed in the dark. It is not bathing in the sun, but the black smoke coming out of the "big chimney".
