How about taking a bath with cold water in summer?

Take a cold bath, help blood vessels do gymnastics and enhance immunity.

It is very hot in summer, and many people will take a cold bath to cool off. Taking a cold bath can relieve summer heat and enhance immunity, which is called "vascular gymnastics". After continuous exercise, you can take it not only in summer but also in winter. But taking a cold bath has steps and taboos to avoid causing physical discomfort.

When taking a cold bath, the skin surface will turn white due to the contraction of cold water before 1 to 2 minutes, and blood will flow to the depths of internal organs. But after washing for 2 to 3 minutes, the blood will be redistributed, the blood will flow back to the skin surface, and the skin will gradually turn red. The whole process is like doing vascular gymnastics.

First, get used to taking a cold bath. It's best to start exercising in summer, and take a cold bath in winter when your body can adapt.

Warm up first

Like exercise, you should warm up before taking a cold bath. You can make your body move, or rub it for a few minutes to make your skin a little red and hot, or you can do a massage while rubbing.

It shouldn't take long.

The whole process from taking a cold bath to taking a cold bath can't last too long, 10 minutes or so, and the longest is not more than half an hour. If you often take a cold bath and are in good health, you can use the three-temperature method of alternating cold and hot, and the effect will be better, but you must try it in good health.

Keep warm after washing

In addition to taking a cold bath for a long time, wrap a bath towel or put on a bathrobe immediately after washing, and put on clothes to keep warm immediately to avoid catching a cold.

Rinse the limbs first.

In order to let your body adapt to cold water slowly, you should take a cold shower before soaking. When rushing, you should also pay attention to starting from your hands, feet and limbs for a few minutes, and then rushing to your chest. Don't be too irritating to your body.

You can add essential oil.

It is best not to take a cold bath for more than 5 minutes, and you can add some essential oil when taking a bath. Dr Andy Sun said that he personally likes to add a little mint to completely relax his body. After taking a cold bath at night, he can go to bed immediately and sleep soundly.

If you feel uncomfortable, don't stop.

When taking a cold shower, if you feel shivering with cold, your skin is turning white and dizzy, stop immediately and don't try to be brave.

Pay more attention

Taking a cold bath is good for your health, but not everyone can try it. Don't take a cold bath in the following situations, and it's cold in winter. Unless you are used to taking a cold bath or you are strong, don't try it easily.

Cold bath taboo

hypertension

When you have symptoms of high blood pressure such as neck pain, dizziness and headache, don't take a cold bath, because when you take a cold bath, blood vessels will contract rapidly and your blood pressure will soar.

heart disease

When taking a cold bath, blood rushes to the heart, which will make the heart unable to load. People with poor liver, kidney and lung function are also not suitable for taking a cold bath, because their organs may not be able to load.

Drink wine

After drinking, the skin pores are fully open, and when taking a cold shower, it will shrink rapidly due to cold water, and the impact is too great for the body to bear.

After strenuous exercise

When you engage in strenuous exercise, just like drinking, you will sweat and get hot, so that the pores of your skin will be fully opened, and taking a bath immediately will make your body unbearable.

insufficiency of Qi and Blood

During menstruation, pregnancy and confinement, women are weak, lack of qi and blood, and poor blood circulation, so they are not suitable for taking a cold bath for vascular gymnastics.

I just had enough.

When eating, blood will flow to the stomach to help the food digest. If you take a cold bath immediately, it will make blood flow from the stomach to other internal organs of the body and affect digestion. It takes half an hour to take a cold bath after dinner.

out of sorts

If you have a cold, a fever or any inflammation, you are not feeling well. Because you are weak, you are not suitable for taking a cold bath.

There are many benefits

Not easy to catch a cold

People who often catch a cold and have poor immunity can take more cold baths to increase their cold tolerance and enhance their immunity. In addition, blood will flow to internal organs, which can take out visceral toxins and promote visceral metabolism.

Help sleep and soothe nerves.

Faster heartbeat and dry mouth can lead to autonomic nerve disorder. Taking a cold bath can make the autonomic nerves not excited, which is helpful to sleep and soothe the nerves.

Help digestion.

Taking a cold bath can promote gastrointestinal peristalsis and improve digestive function, but don't take a cold bath within half an hour after meals, so as to avoid the rapid outflow of blood from the stomach and cause indigestion.

The skin is elastic.

Taking a cold bath often can make blood flow to subcutaneous tissue, making skin softer and more elastic.

Is taking a cold bath good for your health? Opinions vary.

My opinion is:

1. When taking a cold bath, the human body will feel cold because of the low water temperature, which will produce a series of stress reactions, such as rapid heartbeat, high blood pressure, muscle contraction and nervous tension. It can not only eliminate fatigue, but also easily cause colds and should be avoided as much as possible. For those friends who are in poor health, they should not bathe in cold water, otherwise their resistance will be poor, and diseases such as colds and fever will be caused by cold stimulation.

In some areas, the climate changes greatly, which makes the flu advance. It is unwise for some friends to take a cold bath as soon as possible. But you can insist on washing your face with cold water for a long time, promote blood circulation, prevent colds and rhinitis, and make your skin more shiny and elastic.

For winter swimmers who insist on exercising all the year round, there needs to be a process of learning and adapting, which needs to be persisted all the year round. However, the cold water bath movement must be gradual: in autumn, the temperature gradually decreases, and the human body gradually adapts to the cold cold water, so that in late autumn and winter, the cold water bath will not feel too cold. The "step by step" of cold water bath should also include "from local to whole body", "from high to low" of water temperature and "from short to long" of bathing time.

Precautions for taking a cold bath;

1. Women shouldn't take cold showers.

When taking a cold bath, because the water temperature is too low, the human body will feel cold and produce a series of stress reactions, such as rapid heartbeat, high blood pressure, muscle contraction and nervous tension. It can not only eliminate fatigue, but also easily cause colds and should be avoided as much as possible. Because of its special physiological reasons, especially when female friends are in menstruation, lactation and pregnancy, the stimulation of cold water will cause endocrine disorders, amenorrhea and abdominal pain, and many bacteria will also enter the vagina to cause gynecological diseases such as vaginitis, which will seriously affect women's future pregnancy and health.

2. People with coronary heart disease should not take a cold bath! !

Cold water bath can promote the blood circulation of blood vessels in the whole body and enhance the opening and closing function of skin pores. Long-term adherence to cold water bath can improve the cold resistance of the body, thus helping to prevent diseases such as colds.

Cold bath is really good for healthy people, but it is not suitable for patients with coronary heart disease. Because cold water stimulation can induce angina pectoris, even acute myocardial infarction or sudden death. According to clinical research, the peak of acute myocardial infarction is from 1 1 to April of the following year, and the main reasons may be related to cold stimulation and sudden climate change. Because the patient is stimulated by cold, the α adrenergic receptor of the body is excited, the arterioles of the whole body are contracted, the ejection resistance of the heart is increased, and the oxygen consumption of the myocardium is increased.

Coronary artery disease in patients with coronary heart disease, coronary blood flow can not be increased accordingly, which eventually leads to myocardial ischemia and angina pectoris.

Therefore, patients with coronary heart disease should pay special attention to cold and warmth in cold season, and avoid taking a cold bath to avoid an acute attack of coronary heart disease.

3. Don't take a cold bath in after making love.

In the process of "sharing the same bed", the blood circulation of the whole body is accelerated, which is manifested by increased blood pressure, accelerated heartbeat, enhanced gastrointestinal peristalsis, flushing of the skin, opening of sweat gland pores and sweating. Therefore, after * * is over, you will feel irritable and thirsty. Some people are eager to drink cold drinks or take a cold bath to sweat, which is not good for their health.

Because during sexual life, the blood vessels in the gastrointestinal tract are dilated, drinking cold drinks will suddenly damage the gastrointestinal mucosa and even cause gastrointestinal discomfort or colic before the congestion of the gastrointestinal mucosa returns to normal. Similarly, in the process of * *, the skin blood vessels of the whole body are also congested and dilated, and the pores of sweat glands are in an open state of perspiration. At this time, if the skin is blown by cool wind or bathed in cold water, the blood vessels of the skin will suddenly contract, so that a large amount of blood will return to the heart and increase the burden on the heart; At the same time, it will also cause the sweat gland drainage hole to suddenly close, so that sweat is stored in the sweat gland, which is harmful to health.

If you feel thirsty, you might as well drink a little warm water first. After sexual intercourse 1 hour or so, after the blood circulation of various organs of the body returns to normal, it is advisable to take a cold bath.

4. Take a cold shower carefully after sweating in summer.

After sweating in summer, you can't take a cold bath immediately. This is because the temperature is high in summer and the body generates more heat during exercise. Sweat evaporation and skin vasodilation are important ways to dissipate heat.

At the end of exercise, the human body is still in a state of vigorous metabolism, increased heat production and vasodilation of the skin. At this time, if the skin is immediately stimulated by cold water, the blood vessels of the skin will contract through nerve reflex, which will hinder perspiration and heat dissipation, but it will make heat dissipation difficult and body temperature rise. At the same time, the decrease of skin blood flow suddenly increases the blood flow back to the heart, which will increase the burden on the heart.

There is also the body from the hot environment into the cold environment, too late to adapt to the adjustment, often easy to catch a cold or cause gastrointestinal cramps. Muscle fatigue and tension increase after exercise, and then cold stimulation may also cause cramps. Drink some salt water properly after sweating in summer, then rest for about 1 hour, do some preparatory activities and take a cold bath. If conditions permit, it is best to take a warm bath.

5. Take a cold shower carefully after work.

After sweating in summer, you can't take a cold bath immediately. This is because at the end of labor, the human body is still in a state of vigorous metabolism, increased thermogenesis and vasodilation of the skin. If you take a cold bath immediately, your skin will be stimulated by cold water, which will cause the skin blood vessels to contract. In this way, sweating and heat dissipation will be blocked, but it will make heat dissipation difficult and body temperature rise. At the same time, the decrease of skin blood flow suddenly increases the blood flow back to the heart, which will increase the burden on the heart. Muscle fatigue and tension increase after work, and then cold stimulation may also cause cramps, colds or gastrointestinal spasms.
