Being washed by cold water at room temperature makes you feel completely cold, even when the temperature is high in summer.

Taking a cold bath helps blood vessels do gymnastics to enhance immunity

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

When taking a cold shower, the skin surface will turn white due to cold water contraction in the first 1 to 2 minutes, and the blood will flow to the deep internal organs. However, after washing for 2 to 3 minutes, the blood will be redistributed, and 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 is best to take exercise from summer. When your body can adapt, you can take a cold bath in winter.

Warm up first

Just like exercise, you should warm up before taking a cold bath. You can make your body move, or rub your skin with your hands for a few minutes, which will make your skin a little red and hot. You can also do a tendon massage when rubbing.

It should not be too long

The whole process from taking a cold shower to soaking in a cold bath should not be too long, about 1 minutes, and the longest should not exceed half an hour. If you take a cold shower frequently and your health is good, you can adopt the three-warm method of alternating cold and hot, and the effect will be better, but you must try it when your health is good.

keep warm after washing

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

Flush your limbs first

In order to let your body get used to cold water slowly, when you take a cold shower, you should rinse first and then soak. When you rinse, you should also pay attention to washing your hands, feet and limbs for a few minutes before flushing your chest, so as not to be too irritating and your body can't stand it.

essential oil can be added

It is best not to take a cold bath for more than 5 minutes, and some essential oil can be added 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 very well.

don't stop

when taking a cold shower, if you feel cold and shivering, your skin keeps turning white, dizziness and other physical discomfort, stop immediately and don't try to be brave.

Pay more attention to

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 very strong, don't try it easily.

contraindications to cold bath

Hypertension

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

After drinking

After drinking, the pores of the skin are fully open, and when taking a cold shower, it will shrink rapidly due to cold water, which will make the body unbearable.

After strenuous exercise

When engaged in strenuous exercise, just like drinking, you will sweat and get hot, which will make the skin pores fully open and take a shower immediately, which will make your body unbearable.

Deficiency of Qi and Blood

During menstruation, pregnancy and confinement, women are less suitable for taking a cold bath for vascular gymnastics because of their weak body, deficiency of Qi and blood and poor blood circulation.

Just after eating

When eating, blood will flow to the stomach to help the food digest. If you take a cold bath immediately, blood will flow from the stomach to other internal organs of the body, which will affect digestion. You should take a cold bath half an hour after eating.

physical discomfort

cold, fever or any inflammation are unwell, so it is not suitable to take a cold bath because of physical weakness.

There are many benefits

It is 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 the viscera, which can bring visceral toxins out and promote visceral metabolism.

Help sleep and soothe the nerves

Faster heartbeat and dry mouth will lead to autonomic nervous disorder, etc. Taking a cold bath can make autonomic nerves not excited and help sleep and soothe the nerves.

Helps 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 to avoid blood flowing out of the stomach quickly and indigestion.

The skin is elastic

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

is a cold bath good for your health? There are different opinions.

My opinion is:

1. When taking a cold bath, because the water temperature is too low, people will feel cold and produce a series of stress reactions, such as rapid heartbeat, high blood pressure, muscle contraction, nervous tension, etc., which can not only eliminate fatigue, but also easily cause colds, and should be avoided as far as possible. For those friends with poor physical fitness, it is even more impossible to take a bath with cold water, otherwise their resistance is poor, and diseases such as colds and fever will be caused by the stimulation of cold.

2. In some areas, the climate changes greatly, which makes the flu advance. It is not wise for some friends to take a cold bath as early as possible. However, you can persist in 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.

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

precautions for taking a cold bath;

1. Women should never take a cold bath.

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, nervous tension, etc., which can not only eliminate fatigue, but also easily cause colds, and should be avoided as far as possible. Because of its special physiological reasons, especially female friends during menstruation, lactation and pregnancy, the stimulation of cold water will cause female 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 physical health.

2. People with coronary heart disease should never take a cold bath! !

cold water bath can promote the blood circulation of blood vessels all over the 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 colds and other diseases.

cold water bath is really beneficial to healthy people, but it is not suitable for patients with coronary heart disease. Because cold water stimulation can induce angina pectoris and even acute myocardial infarction or sudden death. According to clinical research, the peak of acute myocardial infarction is from November to April of the following year, and its main reasons may be related to cold stimulation and sudden climate change. Because the patient is stimulated by cold, it excites the α -adrenergic receptor of the body, causing the systemic arterioles to contract, increasing the ejection resistance of the heart and increasing the oxygen consumption of the myocardium.

Patients with coronary heart disease have coronary artery lesions, and the 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 cold showers to avoid acute attack of coronary heart disease.

3. Don't take a cold bath after sex

In the process of "sharing a 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, sweat gland pores opening and sweating, and so on. Therefore, after the end of * *, you will feel irritable and thirsty. Some people are eager to drink cold drinks, or take a cold bath to get rid of sweat, which is not good for their health.

Because the blood vessels in the gastrointestinal tract are dilated during sexual life, before the gastrointestinal mucosa congestion returns to normal, the intake of cold drinks will cause the gastrointestinal mucosa to suddenly get cold and suffer certain damage, and even cause gastrointestinal discomfort or colic. By the same token, in the process of * *, the skin blood vessels in 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 flow back to the heart, which will 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 will be stored in the sweat gland and it will be harmful to health.

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

4. Take a cold bath carefully after sweating in summer exercise

You can't take a cold bath immediately after sweating in summer exercise. This is because the temperature is high in summer, and the body produces 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 dilated blood vessels. At this time, if you take a cold bath immediately, your skin will be stimulated by cold water, which will cause skin blood vessels to contract through nerve reflex. As a result, 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.

In addition, when the body changes from a hot environment to a cold environment, it is too late to adapt and adjust, and it is often easy to catch a cold or cause gastrointestinal spasm. Muscle fatigue and tension increase after exercise, and then cold stimulation may also cause cramps. After sweating in summer, you should drink some salt water properly, 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

You can't take a cold shower immediately after working and sweating in summer. This is because at the end of labor, the human body is still in a state of vigorous metabolism, increased heat production and dilated skin blood vessels. If you take a cold bath immediately, the skin will be stimulated by cold water, which will cause the skin blood vessels to contract. As a result, 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.
