What are the advantages and disadvantages of taking a cold bath in summer?

In hot summer, in addition to blowing air conditioners and eating popsicles to cool off, many people also choose to drink cold water to cool down physically. When they came out, they were sweating profusely. It's uncomfortable to take a cold bath at this time, but do you know what are the advantages and disadvantages of taking a cold bath in summer?

For some people with good physique, taking a cold bath can really play a role in strengthening the body:

First, promote blood circulation.

When the human body comes into contact with cold water, blood vessels contract when it is cold. At this time, blood will flow to our internal organs. When our body adapts to this water temperature, blood will flow back to the skin surface. This process can improve blood circulation and blood quality.

Second, promote digestion.

When blood flows to our internal organs or deep tissues, the metabolic capacity of our internal organs will be enhanced, the blood circulation in abdominal cavity will be accelerated, and the function of gastrointestinal tract will become more active, thus stimulating our digestive system and improving our absorption capacity.

Third, regulate emotions.

Cold water can activate the sympathetic nerve in our body and raise the level of adrenaline. These hormones can increase the contractility of our heart and make our heart beat faster, thus producing a feeling of "refreshing".

? Fourth, reduce the chance of arteriosclerosis.

In the process of taking a cold bath, our blood vessels will suddenly contract, so that the elasticity of blood vessels can be exercised through one contraction after another. If the blood vessels do not exercise for a long time, they may become hardened, so proper cold water bath can prevent cardiovascular diseases, such as hypertension and coronary heart disease, to some extent.

But not everyone is suitable for taking a cold bath. For example, people suffering from hypertension, coronary heart disease, acute hepatitis, tuberculosis and rheumatoid arthritis are not suitable for taking a cold bath, which may easily lead to aggravation of their illness and be harmful to their health. In addition, it is not advisable to take a cold bath after drinking, eating, fasting and strenuous exercise, which may easily lead to diseases. For women, it is not suitable to take a cold bath during menstruation or postpartum.

In addition, people with relatively cold constitution often take a cold bath, which will easily lead to the invasion of dampness and aggravate the moisture in their bodies. People with bad spleen and stomach will wash cold water more, and spleen dampness will be aggravated.

For normal people, taking a cold bath has the following disadvantages:

? First, it is easy to cause diarrhea.

In the process of taking a cold bath, cold water will stimulate our abdomen. Once the abdomen gets cold, it will lead to vasoconstriction and spasm of our gastrointestinal tract, which will lead to diarrhea.

? Second, it causes skin diseases.

You know, the temperature of our skin itself is actually relatively high. If we are suddenly stimulated by cold water, our pores will shrink, so the oil and sweat hidden in the pores will not be cleaned in time. Long-term cold bath can induce a series of skin diseases.

? Third, it causes joint pain.

When we take a cold shower, the water temperature itself is relatively low, which easily leads to moisture entering the body. If you take a cold bath for a long time, it will easily lead to joint pain, which is not conducive to your health.

Therefore, if you want to avoid accidents, you need to take the right cold bath:

First of all, ensure that the water temperature is from high to the end. When washing, rinse with hot water first, and then slowly reduce the temperature of the bath water until the temperature is within your acceptable range. Don't take a cold bath as soon as you get up.

Second, don't take a bath for too long. It is recommended to take a cold bath for two or three minutes at first. When your body's adaptability becomes stronger and you have a certain endurance, you can extend it slightly, but it should not exceed 15 minutes.

Third, in the process of washing, first wash the limbs to let the body have an adaptation process, then drain the body with cold water to adapt the chest and backup to the water temperature, and finally rinse the whole body.

Fourth, it is best to take a cold bath in summer, because the body surface temperature is relatively high in summer, and the adaptability to cold water is relatively strong, and accidents are not easy to occur.
