Hot water can dilate blood vessels and lower blood pressure; Cold water constricts blood vessels. In this way, alternating hot and cold water repeatedly, contracting one by one, is equivalent to massaging blood vessels. This kind of massage is almost more effective than letting anyone press it outside, because it is performed all over the body at the same time.
Many people will think, how to take a bath with cold water in winter? Isn't it easy to catch a cold and have a fever? It's very cold. How can you stand it?
The first thing to emphasize is that this place is alternating with cold water and hot water. Wash in cold water for one minute, then in hot water for one minute. It takes less time to wash cold water like this.
In addition, it is not a cold bath that will cause a cold and fever, because only bacteria and viruses will make the body cold and have a fever. Some people say that you will catch a cold after a cold bath because he did something that made you catch a cold after a bath. For example, blow the air conditioner immediately after taking a shower, because in the air-conditioned room, it is basically closed and there will be many bacteria; Just after taking a shower, all the organs of the body are open, so it is easy to be infected by bacteria and viruses. But as long as you pay a little attention, it doesn't matter
Besides, some people say they are afraid of the cold. In fact, first of all, you are afraid. With the idea of being afraid of cold, it will definitely be cold. Because you were taught never to take a cold bath in winter, because it's too cold.
So you are born with the idea of being afraid of cold, which will make your body very sensitive. In the cold winter, cold water itself stimulates blood vessels to some extent, and then you stimulate it with this fear, not the cold. So, you have to tell yourself that this is good for your health. Just get used to it.
If you get into the habit of taking cold and hot baths, the benefits are simply too much. Can make your joint microcirculation unobstructed. Microcirculation is the easiest place for human body to accumulate garbage, but this contraction can squeeze out the garbage at the microcirculation of blood vessels. Therefore, hot and cold water bath is a good method for arthritis and various inflammations.
Because it can promote blood circulation, it also has special effects on patients with hypertension. It can speed up the blood flow with high blood viscosity, make the blood flow slow, and thus lower blood pressure. In addition, hot and cold water bath also has a good effect on cerebral hemorrhage.
Hot and cold water bath is helpful for the rehabilitation of almost any disease. As long as the habit is formed, the cold resistance will be enhanced, so that you can wear less clothes in winter.
In developed countries in Europe and America, many people almost wear skirts or a pair of thin pants when they go out in winter, but in China, such people are rarely found; Because of physical differences, I am wrapped in a thick down jacket, but the thick down jacket wraps the sub-health body that may get sick at any time.
Cold, pore contraction, vasoconstriction, high blood pressure, enhanced blood circulation, improved blood supply to surrounding tissues, increased blood supply to the brain, and increased blood obtained by internal organs;
Heat, pore dilation, vasodilation, blood pressure drop, blood supply slow down, blood flows to skin appearance, visceral ischemia, skin blood flow increase, and improve the health of skin, mucosa and external tissues.
A cold is an indescribable medicine; Heat is another good medicine.
Except for a cold, no medicine, nutrition, medical technology or regimen in the world can achieve the effect that a cold can achieve in an instant.
That effect is amazing. Blood is transported from the skin surface to the visceral center; In an instant, all internal organs increase blood supply, blood vessels contract and circulation improves. Heat transfers blood and transports it to the outside of skin and mucous membrane.
I (Lin Haifeng) bathe alternately in hot and cold all year round. You can try it enthusiastically, and I believe you will love it.
Exercise is to improve blood circulation, and alternating hot and cold bathing is the most effective and free way to improve blood circulation.
