How are hot springs formed?

1. The formation of hot springs can generally be divided into two types.

2. One is formed by magma inside the earth's crust, or produced by volcanic eruptions. In the dead and alive mountainous areas where volcanic activity has occurred, the surface is uplifted by the movement of the crustal plates, and there is still uncooled magma under the ground, which will continuously release a large amount of heat energy. Due to the concentration of heat from this type of heat source, as long as there are porous water-bearing rock layers nearby, they will not only be heated to become high-temperature hot water, but most of them will boil into steam. Most of them are sulfate springs.

3. The second is formed by the infiltration cycle of surface water. That is to say, when rain falls to the surface and penetrates downward, it penetrates into the aquifer deep in the earth's crust to form groundwater (sandstone, conglomerate, volcanic rock, these good aquifers). Groundwater is heated by the geothermal heat below and becomes hot water. Most deep hot water contains gas, mainly carbon dioxide. When the temperature of hot water rises, if there is a dense, impermeable rock layer blocking the way, the pressure will become higher and higher, so that the hot water and steam are in a high-pressure state, and they will rush up as soon as there is a crack.

Why does hot springs keep your skin from wrinkling?

The skin tends to wrinkle when soaked in water for a long time because the concentration of epidermal cell fluid is greater than that of water. Over time, water will flow to the direction of greater concentration. At this time, epidermal cells absorb water and swell. The squeezing between cells will cause the epidermis to bulge upward and wrinkle. Hot spring water contains a large amount of mineral components, and the osmotic pressure is not much different from that of body fluids, so it is not easy to cause the skin to absorb water and wrinkle.

How to wash the swimsuit that turns yellow after soaking in hot springs

1. When entering the shower room, rinse the swimsuit with warm running water, shake off the water and put it into a clean plastic bag. Because the water in the swimming pool contains chlorine and the sea water contains salt. When you get home, do not use the washing machine to wash it. Instead, take it out of the bag quickly. Do not use washing powder or soap to wash it. Instead, use one or two drops of shampoo, shower gel and mild detergent to rinse it gently.

2. After rinsing, put a drop of Jinsong softener in it and soak it for a while. Note that you should not wring or rub the swimsuit hard, but squeeze the water with your hands, or shake it. It is better to wipe it with a clean towel.

3. Drying: Hang the swimsuit in the shade like a towel. Do not use a clip to hold a corner to dry it. The swimsuit should not be exposed directly to the sun. It is okay in winter because the radiation is not so strong. But be careful not to get cold, which will also cause great damage to the swimsuit.
