​The disadvantages of taking a cold shower

We know that taking a cold shower is a very good way to maintain health. It is not only good for our skin but also can promote our metabolism and blood circulation. It can improve our immune function and the body's disease resistance. Taking a cold shower is a health-preserving effect that many people like to choose, but we should also pay attention to the disadvantages of taking a cold shower.

There are many taboos in taking cold showers. If we do not pay attention to these taboos, taking cold showers will not only fail to play its due health-preserving and health-care effects, but may also have adverse effects.

I was sweating profusely and feeling extremely hot, so of course I wanted to cool down as quickly as possible. Some people take cold showers at this time to relieve the suffering of heat and irritability, which is unscientific. Because, due to the sudden stimulation of cold water, the skin blood vessels immediately contract, the blood circulation resistance increases, the heart and lung burden increases, and at the same time the body's resistance is reduced, potential bacteria and viruses in the human body will take advantage of the opportunity to enter, thus causing disease.

If you like to wash your hair with cold water in the summer, it will cause headaches in the winter or unbearable headaches when you catch a cold. Therefore, you should avoid washing your hair with cold water in summer, and blow dry your hair in time after washing. It is also forbidden to blow cold air directly into the air from electric fans or air conditioners for a long time.

You cannot take a cold shower right after exercising or exercising, because the human body is still in a state of vigorous metabolism, increased heat production, and dilated skin blood vessels. If you take a cold shower immediately at this time, the skin will be stimulated by the cold water, which will cause skin blood vessels to contract through nerve reflexes. As a result, sweating and heat dissipation will be hindered, which will make heat dissipation difficult and increase body temperature. At the same time, the decrease in skin blood flow causes a sudden increase in the amount of blood returning to the heart, which increases the burden on the heart.

Taking cold showers at will in the summer will cause wind, cold and dampness to accumulate in the meridians, making people susceptible to various joint pains and limb numbness, rheumatism, rheumatoid arthritis, joint pain caused by trauma, etc. These rheumatic symptoms often occur in cold weather and disappear in hot weather.

In the summer, you cannot take a cold shower immediately after sweating while working. This is because just after finishing work, the human body is still in a state of vigorous metabolism, increased heat production, and dilated skin blood vessels. If you take a cold shower immediately, the skin will be stimulated by the cold water, which will cause the skin blood vessels to contract. As a result, sweating and heat dissipation will be hindered, which will make heat dissipation difficult and increase body temperature. At the same time, the decrease in skin blood flow causes a sudden increase in the amount of blood returning to the heart, which increases the burden on the heart. After work, muscles become fatigued and tense. If they are exposed to cold at this time, they may cause cramps, and they may also be prone to colds or gastrointestinal spasms.

Due to special physiological reasons, especially for women during menstruation, lactation and pregnancy, the stimulation of cold water when taking a cold shower may cause endocrine disorders, amenorrhea, abdominal pain, and many bacteria may enter the vagina and cause gynecological diseases such as vaginitis, which may have a certain impact on women's future pregnancy and physical health.

Cold water baths are indeed beneficial for healthy people, but they are not suitable for patients with coronary heart disease. Because cold water stimulation can induce angina pectoris or even acute myocardial infarction or sudden death. Clinical studies have shown that the peak incidence of acute myocardial infarction is from November to April of the following year, and the main reason may be related to cold stimulation and sudden climate changes. Because when the patient is exposed to cold stimulation, the body's α-adrenergic receptors are excited, causing contraction of small arteries throughout the body, increased cardiac ejection resistance, and increased myocardial oxygen consumption.

You cannot take a cold shower after drinking, because after drinking and sweating, the glucose in the human body is converted into heat and consumed, which greatly reduces blood sugar levels and lowers body temperature. The alcohol contained in wine can inhibit the normal activity of the liver and hinder the recovery of glucose storage in the body, so that blood sugar cannot be replenished in a timely and effective manner. This can easily lead to symptoms such as dizziness, headache, blurred vision, general weakness, and in severe cases, hyperglycemic coma. Therefore, after drinking and sweating, you should not take a cold shower immediately to avoid dangerous situations that endanger your health.

Above we introduced that taking cold showers has many benefits. Taking cold showers regularly can promote blood circulation and metabolism, and can improve skin immunity.
